Refluks u niemowląt
Etiologia i przyczyny

Refluks żołądkowo-przełykowy (GER) u niemowląt jest zjawiskiem fizjologicznym wynikającym głównie z niedojrzałości dolnego zwieracza przełyku (LES) oraz specyficznej anatomii niemowlęcia, w tym rozwarty kąt Hisa i krótszy przełyk. Głównym mechanizmem patofizjologicznym jest przemijające rozluźnienie LES (tLESR), odpowiadające za 94% epizodów refluksu. Czynniki takie jak dieta płynna, pozycja leżąca, niedojrzałość układu pokarmowego oraz techniki karmienia (np. przekarmianie, aerofagia) zwiększają ryzyko wystąpienia refluksu. Refluks u niemowląt zwykle pojawia się między 2-3 tygodniem życia, osiąga szczyt w 4-5 miesiącu, a około 90% dzieci wyrasta z niego przed ukończeniem 12 miesiąca życia, co wiąże się z dojrzewaniem LES, wydłużeniem przełyku oraz wprowadzeniem pokarmów stałych.

Etologia refluksu u niemowląt

Refluks żołądkowo-przełykowy (GER) to częste zjawisko u niemowląt, charakteryzujące się cofaniem się treści żołądkowej do przełyku, a niekiedy również do jamy ustnej lub nosa. W przeciwieństwie do choroby refluksowej przełyku (GERD), która powoduje powtarzające się, dokuczliwe objawy lub prowadzi do powikłań, zwykły refluks (GER) jest procesem fizjologicznym i normalnym u zdrowych niemowląt, który zazwyczaj nie powoduje dyskomfortu ani uszkodzeń przełyku12.

Przyczyny fizjologiczne

Istnieje kilka czynników fizjologicznych, które przyczyniają się do występowania refluksu u niemowląt:

Niedojrzały dolny zwieracz przełyku (LES) – Główną przyczyną refluksu u niemowląt jest niedojrzałość lub słabe napięcie dolnego zwieracza przełyku. Ten pierścień mięśniowy, funkcjonujący jak jednokierunkowy zawór między przełykiem a żołądkiem, u niemowląt nie jest jeszcze w pełni rozwinięty. W rezultacie zwieracz może się nieprawidłowo rozluźniać lub otwierać, gdy nie powinien, pozwalając treści żołądkowej na cofanie się do przełyku345.

Przemijające rozluźnienie dolnego zwieracza przełyku (tLESR) – Jest to obecnie uważane za główny mechanizm refluksu żołądkowo-przełykowego, odpowiadający za 94% epizodów refluksu u dzieci i dorosłych. Polega na nagłym spadku ciśnienia w LES do poziomu ciśnienia wewnątrzżołądkowego, niezwiązanym z przełykaniem i o stosunkowo dłuższym czasie trwania niż rozluźnienie wywołane przełknięciem6.

Anatomia niemowlęca – U niemowląt kąt Hisa (utworzony przez przełyk i oś żołądka) jest rozwarty, co zmniejsza skuteczność bariery przeciwrefluksowej. Ten kąt zmniejsza się w miarę rozwoju niemowlęcia7. Ponadto niemowlęta mają krótszy przełyk i mniejsze żołądki, co zwiększa prawdopodobieństwo wystąpienia refluksu8.

Dieta płynna – Niemowlęta spożywają względnie dużą objętość płynów w porównaniu do swojej wielkości, co zwiększa ryzyko przepełnienia żołądka i refluksu9. Ponadto dieta oparta wyłącznie na mleku czy formule jest również czynnikiem predysponującym10.

Pozycja pozioma – Niemowlęta spędzają większość czasu w pozycji leżącej, co eliminuje korzystny wpływ grawitacji pomagający utrzymać treść żołądka na miejscu1112.

Niedojrzały układ pokarmowy – Ogólna niedojrzałość układu trawiennego niemowlęcia, w tym zdolności do koordynacji procesów trawiennych, przyczynia się do występowania refluksu13.

Przyczyny patologiczne

W niektórych przypadkach refluks może być objawem poważniejszych schorzeń:

Przepuklina rozworu przełykowego – Jest to stan, w którym część żołądka przemieszcza się przez otwór w przeponie do klatki piersiowej. Przepuklina rozworu przełykowego znacząco zwiększa ryzyko GERD u niemowląt1415.

Alergie i nietolerancje pokarmowe – Alergia na białko mleka krowiego jest najczęstszą przyczyną nietolerancji pokarmowej prowadzącej do refluksu u niemowląt. Badania wykazały związek między refluksem a alergią na białko mleka krowiego, a objawy obu schorzeń mogą się pokrywać. Usunięcie alergenu z diety karmiącej matki lub zmiana mieszanki na hydrolizowaną może zmniejszyć stan zapalny i sprawić, że refluks stanie się fizjologiczny i bezbolesny161718.

Gastropareza – Opóźnione opróżnianie żołądka (gastropareza) prowadzi do utrzymywania się pokarmu w żołądku przez dłuższy czas, co powoduje utrzymywanie się wysokiego ciśnienia w żołądku i predysponuje do refluksu1920.

Zwężenie odźwiernika – Zwężenie odźwiernika to stan, w którym mięsień odźwiernika (znajdujący się na końcu żołądka) staje się pogrubiały i zwężony, co blokuje przejście pokarmu z żołądka do jelita cienkiego. Może to prowadzić do nasilenia refluksu ze względu na zwiększone ciśnienie wewnątrz żołądka2122.

Eozynofilowe zapalenie przełyku – Jest to stan, w którym określony typ białych krwinek (eozynofile) gromadzi się w wyściółce przełyku, powodując jej uszkodzenie. Chociaż przyczyna nie jest w pełni jasna, badania wykazały silny związek między alergią pokarmową a eozynofilowym zapaleniem przełyku2324.

Zaburzenia neurologiczne – Zaburzenia wpływające na mózg lub układ nerwowy, takie jak mózgowe porażenie dziecięce, mogą zwiększać ryzyko refluksu poprzez wpływ na koordynację mięśni uczestniczących w trawieniu, w tym znajdujących się wokół LES2526.

Zespół Sandifer – Ten rzadki stan charakteryzuje się epizodami skręcania i wyginania szyi i pleców, przypominającymi drgawki. Jest to rzadko spotykana konsekwencja GERD2728.

Sposób karmienia niemowlęcia może znacząco wpływać na występowanie refluksu:

Przekarmianie – Karmienie niemowlęcia zbyt dużą ilością pokarmu naraz może powodować refluks. Nadmierna podaż pokarmu wywiera zbyt duży nacisk na LES, co sprzyja ulewaniu2930.

Aerofagia – Połykanie powietrza podczas karmienia może prowadzić do gromadzenia się gazu w żołądku, co zwiększa ciśnienie i powoduje otwieranie się zwieracza przełyku. Gdy powietrze wraca, mleko również się wydostaje. Nieprawidłowy chwyt piersi, trudności z kontrolą przepływu pokarmu czy niewłaściwe techniki karmienia mogą powodować nadmierne połykanie powietrza31.

Pozycja podczas karmienia – Niewłaściwa pozycja podczas karmienia piersią lub butelką może przyczyniać się do refluksu u niemowląt. Podobnie, układanie dziecka w pozycji poziomej natychmiast po karmieniu zwiększa ryzyko refluksu3233.

Częstotliwość karmienia – Niemowlęta są zaprojektowane do częstego spożywania małych ilości pokarmu. Dziecko karmione co trzy godziny musi wypijać dwa razy więcej przy każdym karmieniu niż dziecko karmione co półtorej godziny, co może prowadzić do przepełnienia żołądka34.

Czynniki ryzyka

Niektóre czynniki zwiększają prawdopodobieństwo wystąpienia GERD u niemowląt:

  • Wcześniactwo lub niska masa urodzeniowa3536
  • Zaburzenia neurologiczne, takie jak mózgowe porażenie dziecięce3738
  • Mukowiscydoza3940
  • Padaczka41
  • Wrodzone zaburzenia przełyku, w tym wcześniejsza operacja korekcyjna atrezji przełyku4243
  • Astma4445
  • Otyłość4647
  • Rodzinny wywiad refluksu4849
  • Ekspozycja na dym tytoniowy i kofeinę5051
  • Nieprawidłowy mikrobiom jelitowy52

Czynniki środowiskowe

Na występowanie refluksu u niemowląt mogą wpływać również czynniki związane ze środowiskiem i stylem opieki:

Fizyczna separacja między rodzicem a dzieckiem – Niemowlę jest skrajnie niedojrzałe po urodzeniu, a jego układ nerwowy w dużej mierze polega na regulacji przez dorosłych. Jeśli dziecko nie ma kontaktu z dorosłym, trawienie nie działa optymalnie. Separacja może powodować stres i prowadzić do wymiotów oraz płaczu53.

Ekspozycja na dym tytoniowy i kofeinę – Palenie papierosów (jako bierne palenie) i kofeina (w napojach lub mleku matki) rozluźniają dolny zwieracz przełyku, co sprzyja refluksowi. Ponadto, kofeina i nikotyna stymulują produkcję kwasu, więc każdy refluks, który występuje, jest bardziej kwaśny54.

Czynniki dietetyczne u matki karmiącej piersią – Niektóre produkty spożywcze spożywane przez matkę mogą wpływać na napięcie mięśniowe dolnego zwieracza przełyku niemowlęcia, powodując jego dłuższe otwarcie niż normalnie. Obejmują one m.in. czekoladę, napoje gazowane i produkty wysokotłuszczowe5556.

Przebieg kliniczny refluksu u niemowląt

Refluks u niemowląt zwykle zaczyna się około 2-3 tygodnia życia i osiąga szczyt między 4 a 5 miesiącem życia57. Większość przypadków refluksu ulega poprawie wraz z wiekiem dziecka, ponieważ:

  • Zwieracz przełyku dojrzewa i staje się silniejszy58
  • Niemowlę zaczyna spędzać więcej czasu w pozycji pionowej59
  • Wprowadzane są pokarmy stałe, co zmniejsza ilość ulewania60
  • Przełyk wydłuża się61

Około 90% niemowląt wyrasta z refluksu przed ukończeniem pierwszego roku życia, przy czym największa poprawa następuje około 8-10 miesiąca życia, gdy niemowlę zaczyna siedzieć w pozycji wyprostowanej62. Prawie wszystkie przypadki GER ustępują do 18 miesiąca życia lub wcześniej63.

Warto podkreślić, że choć refluks jest powszechny wśród zdrowych niemowląt i zazwyczaj nie powoduje problemów z przyrostem masy ciała, mogą wystąpić przypadki, gdy przybiera on formę choroby refluksowej przełyku (GERD). GERD występuje, gdy refluks powoduje powtarzające się objawy, które są dokuczliwe lub prowadzą do powikłań64.

Powikłania refluksu

O ile zwykły refluks (GER) nie powoduje powikłań, GERD może prowadzić do:

  • Opóźnień w normalnym przyroście masy ciała i wzrostu65
  • Refluksowego zapalenia przełyku66
  • Zwężenia przełyku67
  • Przełyku Barretta68
  • Problemów oddechowych, w tym nawracającego zapalenia płuc, świszczącego oddechu, chrypki6970
  • Dysfunkcji trąbki Eustachiusza, prowadzącej do nawracających infekcji ucha lub utrzymującego się płynu w uchu środkowym71
  • Objawów zapalenia zatok72
  • Trudności w karmieniu i odmowy jedzenia73

W skrajnie rzadkich przypadkach, u niemowląt z refluksem mogą występować epizody bezdechu, które mogą zagrażać życiu74.

Podsumowanie

Refluks u niemowląt jest powszechnym zjawiskiem fizjologicznym, wynikającym przede wszystkim z niedojrzałości dolnego zwieracza przełyku oraz anatomii niemowlęcia. Głównym mechanizmem refluksu jest przemijające rozluźnienie dolnego zwieracza przełyku, odpowiadające za większość epizodów refluksu. Na występowanie refluksu wpływa również dieta płynna niemowląt, ich pozycja leżąca oraz ogólna niedojrzałość układu trawiennego.

Choć większość przypadków refluksu ustępuje samoistnie wraz z dojrzewaniem niemowlęcia, niektóre czynniki predysponujące, takie jak alergie pokarmowe, przepuklina rozworu przełykowego czy zaburzenia neurologiczne, mogą przyczyniać się do rozwoju choroby refluksowej przełyku (GERD), która wymaga interwencji medycznej.

Zrozumienie etiologii refluksu u niemowląt jest kluczowe dla właściwego postępowania terapeutycznego i rozróżnienia między normalnym procesem fizjologicznym a stanem patologicznym wymagającym leczenia. Większość niemowląt wyrasta z refluksu do czasu ukończenia pierwszego roku życia, gdy zwieracz przełyku dojrzewa, a dziecko zaczyna przyjmować więcej pokarmów stałych i spędzać więcej czasu w pozycji pionowej.

    https://www.uptodate.com/contents/gastroesophageal-reflux-in-infants
    Gastroesophageal reflux (GER) is a normal physiologic process that occurs in healthy infants, children, and adults. Most episodes are brief and do not cause symptoms or esophageal injury or result in other complications. In contrast, gastroesophageal reflux disease (GERD) occurs when the reflux episodes are associated with complications such as esophagitis or poor weight gain. The range of symptoms and complications of GERD in children vary with the age of the child. […] Several terms related to gastroesophageal reflux are used inconsistently in the literature and in clinical practice. In this topic review, we will use the terms as follows: Gastroesophageal reflux (GER) – Refers to the passage of gastric contents into the esophagus. Uncomplicated GER – Specifies that the reflux is the normal physiologic process of frequent regurgitation and does not have pathologic consequences; this is sometimes called „simple” reflux.

    https://llli.org/news/why-infant-reflux-matters/
    If you have a new baby, it is likely you’ve heard about reflux or gastro-esophageal reflux disease (GERD). Many mothers worry about whether their baby could have GERD if they are crying or unsettled. You may know other babies who are on medication for reflux. Are large numbers of babies really producing excess acid? It is common that many symptoms attributed to reflux are signs of a feeding issue, and have non-medical solutions. […] Reflux, or gastro-esophageal reflux, is common and physiologically normal. It describes the passage of any gastric contents into the esophagus. Each time we burp, we reflux. Reflux happens to us all frequently. The word “reflux” however, has become confused with GERD (reflux disease). It has become associated with a baby who is vomiting, posseting (regurgitating milk after feeding), waking frequently, wanting to be held often, or not wanting to lie alone. Western society has started to confuse reflux with other issues and behaviors.

    There is a muscle (the lower esophageal sphincter) that acts as a valve between the esophagus and stomach. […] In babies who have reflux, the lower esophageal sphincter muscle is not fully developed and lets the stomach contents back up the esophagus. […] In babies who have GERD, the sphincter muscle becomes weak or relaxes when it shouldn’t.
  • #4 Reflux in Babies: Signs & Treatment
    https://my.clevelandclinic.org/health/diseases/reflux-in-babies
    Reflux happens when the muscular valve that connects your babys esophagus and stomach isnt fully developed or opens when it shouldnt. This valve is a ring-shaped muscle called the lower esophageal sphincter. It relaxes to let food travel from your babys esophagus to their stomach. It then tightens to prevent food from traveling back up. This muscle, like all of your babys muscles, is still developing during your babys first year. So, it might not stay shut as well as it will later on. […] Researchers do know that GERD is more likely to affect babies and children who: Have a hiatal hernia. Have disorders affecting their brain or nervous system. Have cystic fibrosis. Have epilepsy. Are born with conditions affecting their esophagus. Have asthma. Are born early (premature birth). […] Symptoms of GERD in babies include: Spitting up and/or vomiting, which may be forceful. Discomfort or irritability, which may involve crying or arching of the back during feedings. Refusal to nurse or drink from the bottle. Not gaining weight or growing. Vomiting blood. Difficulty swallowing. Cough. Wheezing. Noisy breathing (stridor). Hoarseness. […] GER doesn’t cause complications. However, GERD may lead to: Delays in normal weight gain and growth. Reflux esophagitis. Esophageal strictures. Barretts esophagus. Respiratory problems.

    Gastroesophageal reflux (GER) occurs when contents that have gone down to the stomach come back up into the esophagus. […] For some babies, their LES muscle doesnt close or opens when it shouldnt. […] If there is a problem with the LES, milk or formula and stomach juices (acid) can come back up into the esophagus and may be vomited. This can irritate the esophagus and may cause pain.

    Transient lower esophageal sphincter relaxation (tLESR) – This is currently believed to be the main mechanism of gastroesophageal reflux, accounting for 94% of reflux episodes in children and adults; poor basal LES tone was previously thought to be a cause. […] Chronic LES laxity: Reflux is facilitated when an increase in intraabdominal pressure occurs. […] The major mechanism in infants and children has now been demonstrated to involve increases in tLESRs. […] Gastroesophageal reflux has been associated with significant respiratory symptoms in infants and children. […] An association between gastroesophageal reflux and delayed gastric emptying is recognized.

    https://emedicine.medscape.com/article/930029-overview
    In pediatric gastroesophageal reflux disease (GERD), immaturity of lower esophageal sphincter function is manifested by frequent transient lower esophageal relaxations, which result in retrograde flow of gastric contents into the esophagus. […] The causes and risk factors for gastroesophageal reflux in children are frequently multifactorial. […] Anatomic factors that predispose to gastroesophageal reflux include the following: The angle of His (made by the esophagus and the axis of the stomach) is obtuse in newborns but decreases as infants develop; this ensures a more effective barrier against gastroesophageal reflux. […] Resistance to gastric outflow raises intragastric pressure and leads to reflux and vomiting; examples include gastroparesis, gastric outlet obstruction, and pyloric stenosis.
  • #8 Understanding Reflux in Babies | Children’s Health
    https://www.childrens.com/health-wellness/understanding-reflux-in-babies
    Reflux can be normal in babies, explains Dr. Llanos Chea. Reflux happens in babies because they have a shorter esophagus and smaller stomachs. […] Normal reflux in babies can be caused by the following: Baby’s small anatomy, such as a small stomach and short esophagus; Being overfed; Changing position, such as lying down right after feeding; Not burping enough after a feed. […] If your baby is showing any of the signs of GERD, there’s a possibility that they have an underlying health condition that’s causing the symptoms. […] If lifestyle modifications aren’t enough to control your baby’s reflux symptoms, the next treatment course is typically trying to thicken their feeds. Doing so may decrease reflux symptoms, decrease regurgitation, and increase baby’s weight gain. […] If your baby doesn’t improve using lifestyle modifications or with thickened feeds, your pediatrician will likely refer your baby to a pediatric GI doctor. From there, the GI doctor will typically perform testing to determine if your baby has an underlying health condition that could be causing the reflux symptoms.

    This protective layer prevents micro-organisms from invading the body through these mucous membranes. […] A baby who spits up gets extra protection, first when the milk goes down to the stomach, and again when he spits it up. […] Babies consume a large volume of milk compared to their size. […] This is likely a protective mechanism if a baby has too much milk at once. […] Studies have shown a link between reflux and having an allergy or intolerance to cows milk protein. […] If a mother tries removing dairy products or other known allergens from her diet, the symptoms of reflux will improve if food sensitivity is involved. […] Reflux is sometimes attributed to an immature or undeveloped sphincter muscle a ring of muscle between the stomach and the oesophagus (food pipe) preventing spillage of the stomach contents.
  • #10 Infant reflux | Beacon Health System
    https://www.beaconhealthsystem.org/library/diseases-and-conditions/infant-reflux?content_id=CON-20157204
    If the muscle between the esophagus and the stomach relaxes when the stomach is full, food might flow up the baby’s esophagus. The muscle is called the lower esophageal sphincter. […] In infants, the ring of muscle between the esophagus and the stomach is not yet fully developed. This muscle is called the lower esophageal sphincter, also known as LES. When the LES is not fully developed, it allows stomach contents to flow back up into the esophagus. Over time, the LES typically matures. It opens when a baby swallows and remains tightly closed at other times, keeping stomach contents where they belong. […] Sometimes, infant reflux can be caused by more-serious conditions, such as: GERD. The reflux has enough acid to irritate and damage the lining of the esophagus. […] Some factors that contribute to infant reflux are common in babies and often can’t be avoided. These include lying flat most of the time and being fed an almost completely liquid diet.

    In infants, gastroesophageal reflux (GER) commonly causes […] Experts think several factors lead to GER in infants. For example, in the first 6 months of life, infants spend much of their time lying down and do not have a fully developed esophagus and lower esophageal sphincter. […] Experts are still studying why some infants develop GERD a condition in which GER causes repeated symptoms that are bothersome or leads to complications. Several different factors may play a role. […] Infants are more likely to have GERD if they have certain health conditions, including being born prematurely […] conditions that affect the lungs, such as cystic fibrosis […] conditions that affect the nervous system, such as cerebral palsy […] hiatal hernia, a condition in which the opening in the diaphragm lets the upper part of the stomach move up into the chest […] previous surgery to correct esophageal atresia, a type of birth defect.

    https://www.merckmanuals.com/home/children-s-health-issues/gastrointestinal-disorders-in-children/gastroesophageal-reflux-in-children
    Reflux may be caused by the infants position during feeding; overfeeding; exposure to caffeine, nicotine, and cigarette smoke; a food intolerance or allergy; or an abnormality of the digestive tract. […] Healthy infants have reflux for many reasons. The circular band of muscle at the junction of the esophagus and stomach (the lower esophageal sphincter) normally keeps stomach contents from entering the esophagus. In infants, this muscle may be underdeveloped, or it may relax at inappropriate times, allowing stomach contents to move backward (reflux) into the esophagus. Being held flat during feeding or lying down after feeding promotes reflux because gravity is no longer able to help keep material in the stomach from flowing back up the esophagus. Overfeeding and chronic lung diseases predispose infants to reflux because they increase pressure in the stomach. Cigarette smoke (as secondhand smoke) and caffeine (in beverages or breast milk) relax the lower esophageal sphincter, allowing reflux to occur more readily. Caffeine and nicotine (in breast milk) also stimulate acid production, so any reflux that does occur is more acidic.

    Gastroesophageal reflux happens because of a problem with the ring of muscle at the end of the esophagus. The ring of muscle is called the lower esophageal sphincter. It acts like a one-way valve between the esophagus and the stomach. When your child swallows, the valve lets food pass into the stomach. If the valve is weak, stomach contents can flow back up into the esophagus. […] In babies, this problem happens because the digestive tract is still growing.

    Gastroesophageal reflux is defined as the passage of stomach contents into the esophagus with or without accompanied regurgitation (spitting up) and vomiting. […] The lower esophageal sphincter is the primary barrier to gastroesophageal reflux. Most reflux events are caused by transient lower esophageal sphincter relaxation triggered by postprandial gastric distention. […] The following conditions are associated with increased risk of GERD (listed from highest to lowest odds ratio): hiatal hernia (including congenital diaphragmatic hernia), neurodevelopmental disorders, cystic fibrosis, epilepsy, congenital esophageal disorders, asthma, and prematurity. […] Obesity and parental history of reflux may also be risk factors for GERD in children. […] The diagnosis of gastroesophageal reflux and GERD should be based primarily on history and physical examination findings because other diagnostic tests have not shown superior accuracy.

    4. Low milk intake – Poor weight gain is sometimes diagnosed as “silent reflux” but the most common cause of poor weight gain is lack of milk. When the flow of milk is slow, it is very common for a baby to arch, pull on and off the breast and cry in frustration. Resolution would be to increase milk supply and ensure baby is drinking effectively. […] 5. Allergies/intolerances – When reflux occurs in healthy babies, it is generally painless. Babies are on a milk diet (which neutralizes acid) and the esophagus has a number of defense mechanisms against acidity, so spitting up is usually comfortable or only mildly upsetting for the baby. A minority of babies, however, do become very distressed when refluxing. Allergies can cause inflammation within the body, and cause pain where a non-allergic baby would experience none. Removing the allergen in the breastfeeding parent’s diet allows the inflammation to resolve and for the reflux to become normal physiologic, pain-free reflux again.

    In a few babies, reflux causes complications, such as irritation or damage to the esophagus, asthma, or recurrent pneumonia. In these cases, the condition is called gastroesophageal reflux disease, or „GERD.” This only occurs in a small percentage of babies who spit up frequently. […] Some babies with problematic reflux may also be sensitive to cow’s milk. The challenge is that the symptoms of cow’s milk protein intolerance (CMPI; sometimes called cow’s milk allergy, although this is not a true allergy) may mimic the symptoms of reflux.

    The most common cause of GERD in infants is similar to that of GERD in older children and adults: The lower esophageal sphincter (LES) fails to prevent reflux of gastric contents into the esophagus. […] LES pressure may transiently decrease spontaneously (inappropriate relaxation), which is the most common cause of reflux, or after exposure to agents such as cigarette smoke or caffeine (in beverages or breast milk). […] Other causes include food allergies, most commonly cow’s milk protein allergy. A less common cause is gastroparesis (delayed emptying of the stomach), in which food remains in the stomach for a longer period of time, maintaining a high gastric pressure that predisposes to reflux. […] Infants with GERD do require treatment, typically beginning with conservative measures. […] Acid suppression with a proton pump inhibitor or H2 blocker may help infants with significant GERD.

[…] Some studies have shown that reducing intake of milk and eggs may help, though more research is needed to determine how much this affects the condition. […] Certain foods may be causing acid reflux, depending on your infants age. […] Gastroparesis is a disorder that causes the stomach to take longer to empty. […] A hiatal hernia is a condition in which part of the stomach sticks through an opening in the diaphragm. […] Positioning especially during and after feeding is a frequently overlooked cause of acid reflux in infants. […] Feeding your little one too much at once can cause acid reflux. […] An oversupply of food can put too much pressure on the LES, which will cause your infant to spit up.

    Gastroesophageal reflux (GER) or acid reflux is a common digestive disorder in infants where stomach contents flow back up into the esophagus, causing discomfort and sometimes spitting up. […] The exact cause of acid reflux in babies is not always clear, but several factors may contribute to it, including: Having an immature lower esophageal sphincter (this allows stomach contents to flow back into the esophagus), Overfeeding or too much swallowed air during regular feedings, Having a weak or relaxed diaphragm muscle, Eating too rapidly during feedings, Food sensitivities or food allergies. […] Sometimes, an underlying medical condition may also contribute to acid reflux in babies, such as a neurological disorder or metabolic condition. […] In some cases, infant reflux can be caused by the following: GERD: Also referred to as gastroesophageal reflux disease, a more severe form of GER. It is a chronic condition in which the stomach contents go back (reflux) into the esophagus, causing symptoms such as chest pain, heartburn, and difficulty swallowing.

    In infants, the ring of muscle between the esophagus and the stomach is not yet fully developed. This muscle is called the lower esophageal sphincter (LES). When the LES is not fully developed, it allows stomach contents to flow back up into the esophagus. Over time, the LES typically matures. It opens when your baby swallows and remains tightly closed at other times, keeping stomach contents where they belong. […] Sometimes, infant reflux can be caused by more-serious conditions, such as: […] GERD. The reflux has enough acid to irritate and damage the lining of the esophagus. […] Pyloric stenosis. A muscular valve allows food to leave the stomach and enter the small intestine as part of digestion. In pyloric stenosis, the valve thickens and becomes larger than it should. The thickened valve then traps food in the stomach and blocks it from entering the small intestine.

    What are the causes of the symptoms often associated with reflux? […] 1. Normal baby physiology – Babies have little core strength and many spend a lot of time horizontal. They have a liquid diet and can have an immature valve closing the top of the stomach, so it is leaky. […] 2. Too much milk too quickly – Babies are designed to drink small amounts frequently. A baby feeding every three hours needs to drink twice as much at each feed as a baby drinking every one hour and a half. Overfilling the stomach causes it to stretch, loosening the valve at the top of the stomach – allowing the overflow to escape. Frequent feeding can reduce reflux episodes. […] 3. Aerophagia – This just means swallowing air. A baby who is gulping or spluttering may be taking in more air than they should. A poor latch, scheduled feeds, oral restrictions or difficulty managing flow can all cause excess air to be swallowed. The stomach valve will then open to allow it to escape. As air comes back up, milk escapes too. Correcting the feeding issue so that air isn’t swallowed can reduce or eliminate reflux.

    Most of the time, reflux in babies is due to a poorly coordinated gastrointestinal tract. Many infants with GERD are otherwise healthy; however, some infants can have problems affecting their nerves, brain, or muscles. According to the National Digestive Diseases Information Clearinghouse, a child’s immature digestive system is usually to blame and most infants grow out of the condition by their first birthday. […] In older children, the causes of GERD are often the same as those seen in adults. Also, an older child is at increased risk for GERD if they experienced it as a baby. Anything that causes the muscular valve between the stomach and esophagus (the lower esophageal sphincter, or LES) to relax, or anything that increases the pressure below the LES, can cause GERD. […] Certain factors also may contribute to GERD, including obesity, overeating, eating spicy or fried foods, drinking caffeine, carbonation, and specific medications. There also appears to be an inherited component to GERD, as it is more common in some families than in others.

    Reflux may be caused by the infants position during feeding; overfeeding; exposure to caffeine, nicotine, and cigarette smoke; a food intolerance or allergy; or an abnormality of the digestive tract. […] Healthy infants have reflux for many reasons. The circular band of muscle at the junction of the esophagus and stomach (the lower esophageal sphincter) normally keeps stomach contents from entering the esophagus. In infants, this muscle may be underdeveloped, or it may relax at inappropriate times, allowing stomach contents to move backward (reflux) into the esophagus. Being held flat during feeding or lying down after feeding promotes reflux because gravity is no longer able to help keep material in the stomach from flowing back up the esophagus. Overfeeding and chronic lung diseases predispose infants to reflux because they increase pressure in the stomach. Cigarette smoke (as secondhand smoke) and caffeine (in beverages or breast milk) relax the lower esophageal sphincter, allowing reflux to occur more readily. Caffeine and nicotine (in breast milk) also stimulate acid production, so any reflux that does occur is more acidic.

    Reflux may be caused by the infants position during feeding; overfeeding; exposure to caffeine, nicotine, and cigarette smoke; a food intolerance or allergy; or an abnormality of the digestive tract. […] Healthy infants have reflux for many reasons. The circular band of muscle at the junction of the esophagus and stomach (the lower esophageal sphincter) normally keeps stomach contents from entering the esophagus. In infants, this muscle may be underdeveloped, or it may relax at inappropriate times, allowing stomach contents to move backward (reflux) into the esophagus. Being held flat during feeding or lying down after feeding promotes reflux because gravity is no longer able to help keep material in the stomach from flowing back up the esophagus. Overfeeding and chronic lung diseases predispose infants to reflux because they increase pressure in the stomach. Cigarette smoke (as secondhand smoke) and caffeine (in beverages or breast milk) relax the lower esophageal sphincter, allowing reflux to occur more readily. Caffeine and nicotine (in breast milk) also stimulate acid production, so any reflux that does occur is more acidic.

    https://choc.org/programs-services/gastroenterology/gerd/
    Gastroesophageal reflux disease (GERD) in kids is usually caused by immaturity of the LES that results in weakness of the muscle. However, certain foods, medications, developmental disorders and underlying diseases can also cause GERD in children. […] Some foods seem to affect the muscle tone of the lower esophageal sphincter (LES), allowing it to stay open longer than normal. These include, but are not limited to: Chocolate, Carbonated drinks, High-fat foods. […] The following conditions may increase the likelihood of your child developing GERD: Birth defects, Premature birth, Down syndrome, Cerebral palsy, Head injury, Food allergies, Obesity, Exposure to tobacco smoke, Narrow or short esophagus, Eosinophilic esophagitis. […] Eosinophilic esophagitis also known as EoE, is a disease in which eosinophils (allergy cells) build up in the lining of the esophagus. Although the cause is not clear, research has shown a strong connection between food allergies and EoE. Environmental allergens may also play a role in this disease but more research is needed. Many patients with EoE also experience gastroesophageal reflux disease (GERD).

    The body naturally makes acid, says Dr. Porto. And it makes more once we are eating and chewing. If you’re eating a high acid diet, you’re introducing more acid in addition to that. […] Culprits could include tomatoes (including ketchup), citrus fruits, and spicy foods. Anything that’s carbonated or caffeinated can also cause the esophageal sphincter to remain open.

    GER usually begins at about 2 to 3 weeks of age and peaks between 4 to 5 months old. […] What are the causes of GER? […] Babies may spit up if their stomach is full or their position is changed abruptly, especially after a feeding. […] When it is not fully developed or opens at the wrong time, the stomach contents move back or „reflux” into the esophagus. […] In older children, diet can play more of a role. Large meals and highly acidic or spicy meals can lead to increased GER symptoms. […] GER is also more common in children with overweight or obesity.

    Reflux is common in babies and causes no pain or problems with weight gain in most babies. […] In some cases, medications may help if your baby has a medical condition known as gastro-oesophageal reflux disease (GORD). […] This is common in babies because the muscle at the top of the stomach is not yet strong enough to keep food down. […] Reflux in babies gets better with time as: They start to eat solids. They learn to sit up. The ring of muscle at the top of their stomach gets stronger. […] Although it seems logical that reflux might cause babies to cry, studies show that reflux medications do not improve crying in most babies. […] Gastro-oesphageal reflux disease (GORD) is different to reflux. GORD is a medical condition that needs to be diagnosed by a doctor and affects small numbers of babies who have frequent vomiting AND other symptoms like: choking, coughing or wheezing during feeds, vomiting up blood, distress during feeds or refusal to feed, poor weight gain or weight loss.

  • #64 Gastroesophageal Reflux (GER) in Babies (for Parents) | Nemours KidsHealth
    https://kidshealth.org/en/parents/ger-babies.html
    Gastroesophageal reflux (GER), or reflux, is when food and acid from the stomach go back up into the esophagus and sometimes out the mouth or nose. […] A ring of muscle (the lower esophageal sphincter) separates the esophagus from the stomach. Reflux symptoms happen if this ring relaxes at the wrong time or doesn’t close as it should. This lets stomach contents flow backward into the esophagus, into the back of the throat, and sometimes out the mouth or nose. […] Reflux that happens a lot; causes problems like poor growth, vomiting, or damage to the esophagus; or lasts past a baby’s first birthday is called GERD (gastroesophageal reflux disease).

    Reflux happens when the muscular valve that connects your babys esophagus and stomach isnt fully developed or opens when it shouldnt. This valve is a ring-shaped muscle called the lower esophageal sphincter. It relaxes to let food travel from your babys esophagus to their stomach. It then tightens to prevent food from traveling back up. This muscle, like all of your babys muscles, is still developing during your babys first year. So, it might not stay shut as well as it will later on. […] Researchers do know that GERD is more likely to affect babies and children who: Have a hiatal hernia. Have disorders affecting their brain or nervous system. Have cystic fibrosis. Have epilepsy. Are born with conditions affecting their esophagus. Have asthma. Are born early (premature birth). […] Symptoms of GERD in babies include: Spitting up and/or vomiting, which may be forceful. Discomfort or irritability, which may involve crying or arching of the back during feedings. Refusal to nurse or drink from the bottle. Not gaining weight or growing. Vomiting blood. Difficulty swallowing. Cough. Wheezing. Noisy breathing (stridor). Hoarseness. […] GER doesn’t cause complications. However, GERD may lead to: Delays in normal weight gain and growth. Reflux esophagitis. Esophageal strictures. Barretts esophagus. Respiratory problems.

    During the first year, infants frequently spit up. This is essentially LPR because the stomach contents are refluxing into the back of the throat. However, in most infants, it is a normal occurrence caused by the immaturity of both the upper and lower esophageal sphincters, the shorter distance from the stomach to the throat, and the greater amount of time infants spend in the horizontal position. […] In infants and children, chronic exposure of the laryngeal structures to acidic contents may cause long term airway problems such as a narrowing of the area below the vocal cords (subglottic stenosis), hoarseness, and possibly Eustachian tube dysfunction causing recurrent ear infections, or persistent middle ear fluid, and even symptoms of sinusitis. The direct relationship between LPR and the latter mentioned problems are currently under research investigation.

    Most risk factors for infant GER are unavoidable and include temporary relaxation of lower esophageal sphincter after feeding, frequent large-volume feedings, short food pipe, and laying down. […] The following conditions raise the risk of experiencing infant GERD: hiatal hernia, neurodevelopmental disorders, cystic fibrosis, epilepsy, congenital food pipe disorders, asthma, premature birth, obesity, and parent history of reflux. […] However, in contrast, symptoms of GERD in infants include poor weight gain, weight loss, and failure to thrive, feeding refusal or lengthy feedings, irritability after eating, difficulty swallowing or pain when swallowing, frequent vomiting, stomach pain, chest pain, and pain in other abdominal areas. […] If feeding and positional changes do not improve GERD, and the infant still has problems with feeding, sleeping, and growth, a doctor may recommend medications to decrease the amount of acid in the infant’s stomach.

    GERD is a concern in kids because when stomach contents come up into the esophagus during reflux, infants and children can experience difficulty breathing, episodes of pneumonia and chronic coughing or wheezing. Although rare, infants and children can stop breathing for brief moments due to episodes of gastroesophageal reflux. […] Gastroesophageal reflux is usually diagnosed through physical examination and a review of your child’s medical history. […] In most cases GERD can be relieved through diet and lifestyle changes. Your child’s doctor might recommend the following diet and lifestyle adjustments to help alleviate their symptoms: For infants, Infants with GERD should be held upright for 30 minutes after feedings. […] When symptoms of GERD aren’t improved with diet and lifestyle changes, or in more severe cases, treatment can also include: Medications. If needed, our specialists may prescribe medications to help with reflux.
