Hipoglikemia
Etiologia i przyczyny

Hipoglikemia definiowana jest jako stężenie glukozy we krwi poniżej 70 mg/dl (3,9 mmol/l) u pacjentów z cukrzycą oraz poniżej 55 mg/dl (3,1 mmol/l) u osób bez cukrzycy. Najczęstszą przyczyną hipoglikemii u chorych na cukrzycę jest leczenie insuliną lub lekami przeciwcukrzycowymi, zwłaszcza pochodnymi sulfonylomocznika, a także czynniki takie jak niewłaściwe dawkowanie, pominięcie posiłku, zwiększona aktywność fizyczna czy spożycie alkoholu. U osób bez cukrzycy hipoglikemia jest rzadsza i może wynikać z przyjmowania leków (np. chinina, beta-blokery), zaburzeń hormonalnych (insulinoma, niedoczynność nadnerczy), ciężkich chorób narządów metabolicznych (niewydolność wątroby, nerek), spożycia alkoholu, hipoglikemii reaktywnej po posiłku, długotrwałego niedożywienia, ciężkich infekcji (sepsa) oraz rzadkich stanów autoimmunologicznych i metabolicznych. U dzieci przyczyny hipoglikemii obejmują m.in. ketotyczną hipoglikemię i wrodzone zaburzenia metaboliczne.

Etiologia hipoglikemii

Hipoglikemia to stan, w którym poziom glukozy we krwi spada poniżej wartości prawidłowych, najczęściej definiowany jako stężenie glukozy poniżej 70 mg/dl (3,9 mmol/l) u osób z cukrzycą lub poniżej 55 mg/dl (3,1 mmol/l) u osób bez cukrzycy1. Stan ten może prowadzić do poważnych konsekwencji zdrowotnych, ponieważ glukoza jest głównym źródłem energii dla mózgu i innych organów2. Hipoglikemia może być spowodowana wieloma różnymi czynnikami, które zostaną omówione poniżej.

Hipoglikemia u osób z cukrzycą

Najczęstszą przyczyną hipoglikemii jest leczenie cukrzycy34. W tej grupie pacjentów hipoglikemia może wystąpić z następujących powodów:

  • Przedawkowanie insuliny lub leków przeciwcukrzycowych, szczególnie pochodnych sulfonylomocznika (np. glibenklamid, glipizyd, glimepiryd)56
  • Podanie niewłaściwego rodzaju insuliny lub wstrzyknięcie insuliny do mięśnia zamiast do tkanki tłuszczowej7
  • Pominięcie lub opóźnienie posiłku po przyjęciu insuliny lub leków obniżających poziom glukozy89
  • Niedostateczne spożycie węglowodanów w stosunku do przyjętej dawki insuliny10
  • Zwiększona aktywność fizyczna bez odpowiedniego dostosowania dawki insuliny lub dodatkowego spożycia węglowodanów1112
  • Spożycie alkoholu, szczególnie na pusty żołądek13
  • Utrata wagi, która zwiększa wrażliwość na insulinę14
  • Niewydolność nerek, która może wydłużyć czas eliminacji insuliny z organizmu15
  • Zmiany w organizmie związane z dojrzewaniem, miesiączką, wysoką temperaturą otoczenia lub przebywaniem na dużej wysokości1617

Hipoglikemia u osób bez cukrzycy

Hipoglikemia u osób bez cukrzycy jest zjawiskiem znacznie rzadszym18, ale może wystąpić z różnych przyczyn, które można podzielić na kilka kategorii:

Hipoglikemia związana z lekami

Najpowszechniejszą przyczyną hipoglikemii u osób bez cukrzycy jest przyjmowanie niektórych leków19:

  • Przypadkowe przyjęcie leków przeciwcukrzycowych przez osoby bez cukrzycy20
  • Chinina (Qualaquin) stosowana w leczeniu malarii2122
  • Beta-blokery, szczególnie w przypadku przedawkowania23
  • Pentamidyna stosowana w leczeniu pewnych form zapalenia płuc, szczególnie u osób z AIDS24
  • Niektóre antybiotyki, takie jak gatyfiksacyna, lewofloksacyna, trimetoprim-sulfametoksazol25
  • Salicylany w dużych dawkach26
Hipoglikemia związana z chorobami i zaburzeniami endokrynologicznymi

Zaburzenia hormonalne mogą prowadzić do hipoglikemii poprzez wpływ na metabolizm glukozy27:

  • Insulinoma – rzadki nowotwór trzustki wydzielający nadmierne ilości insuliny, prowadzący często do hipoglikemii na czczo, szczególnie w godzinach porannych2829
  • Niedoczynność nadnerczy (choroba Addisona) – powoduje obniżone stężenie kortyzolu, co może prowadzić do epizodów hipoglikemii3031
  • Niedoczynność przysadki – prowadzi do zmniejszonego wydzielania hormonu wzrostu i może powodować hipoglikemię, szczególnie u dzieci podczas długotrwałego postu lub zwiększonego wysiłku fizycznego32
  • Guzy niewydzielające insuliny (non-islet cell tumors) – mogą wydzielać nadmierne ilości insulinopodobnego czynnika wzrostu 2 (IGF-2), powodując hipoglikemię3334
Hipoglikemia związana z niewydolnością narządową

Ciężkie choroby narządów odpowiedzialnych za regulację metabolizmu glukozy mogą prowadzić do hipoglikemii35:

  • Niewydolność wątroby – ciężkie schorzenia wątroby, takie jak zaawansowana marskość czy ostre zapalenie wątroby, mogą ograniczać zdolność tego narządu do uwalniania glukozy z glikogenu i prowadzić do hipoglikemii3637
  • Niewydolność nerek – może wpływać na metabolizm glukozy i przyczyniać się do hipoglikemii3839
  • Zaawansowana niewydolność serca – może prowadzić do hipoglikemii poprzez zaburzenie przepływu krwi do narządów metabolicznych40
Hipoglikemia związana z alkoholem

Spożycie alkoholu, szczególnie w dużych ilościach i bez jedzenia, jest jedną z najczęstszych pozajatrogennych przyczyn hipoglikemii u dorosłych41:

  • Alkohol hamuje glukoneogenezę (proces tworzenia glukozy) w wątrobie, ale nie wpływa na glikogenolizę (uwalnianie glukozy z glikogenu)42
  • Hipoglikemia występuje najczęściej po kilku dniach spożywania alkoholu, gdy zapasy glikogenu zostają wyczerpane43
  • Picie alkoholu bez jedzenia uniemożliwia wątrobie uwalnianie glukozy z zapasów glikogenu do krwiobiegu44
Hipoglikemia reaktywna i hipoglikemia po zabiegach bariatrycznych

Hipoglikemia reaktywna występuje w ciągu kilku godzin po posiłku, typowo 2-4 godziny po jedzeniu45:

  • Dokładna przyczyna nie jest w pełni poznana, ale prawdopodobnie związana jest z nagłym wzrostem, a następnie spadkiem poziomu cukru we krwi po spożyciu pokarmów bogatych w proste węglowodany46
  • Operacja bariatryczna (obejście żołądkowe) może prowadzić do hipoglikemii poposiłkowej (zespół późnego zrzutu, late dumping syndrome)4748
  • Hipoglikemia po operacji bariatrycznej może być związana z nadmiernym wydzielaniem glukagonopodobnego peptydu-1 (GLP-1) i peptydu YY (PYY)49
Hipoglikemia związana z niedożywieniem

Długotrwałe niedożywienie może prowadzić do hipoglikemii50:

  • Niedobory pokarmowe i długotrwały post mogą wyczerpać zapasy glikogenu potrzebnego do produkcji glukozy51
  • Zaburzenia odżywiania, takie jak anoreksja, mogą prowadzić do hipoglikemii52
  • Stan głodzenia połączony z intensywnym wysiłkiem fizycznym może obniżyć poziom glukozy53
Hipoglikemia związana z ciężkimi infekcjami i sepsą

Ciężkie infekcje, szczególnie sepsa, mogą prowadzić do hipoglikemii54:

  • W stanie krytycznie ciężkiej choroby, jak sepsa, zużycie glukozy może przewyższać jej dostarczanie, glikogenolizę lub glukoneogenezę55
  • Hipoglikemia podczas ciężkiej infekcji jest złym czynnikiem prognostycznym56
Rzadkie przyczyny hipoglikemii

Istnieją również rzadkie przyczyny hipoglikemii, które warto wymienić57:

  • Autoimmunologiczna hipoglikemia, w której organizm wytwarza przeciwciała przeciwko insulinie (zespół insulinooporności typu B) lub przeciwko receptorom insulinowym58
  • Wrodzone defekty metaboliczne, szczególnie u dzieci, takie jak deficyty enzymów wątrobowych ograniczające uwalnianie glukozy wątrobowej (deficyty glukozo-6-fosfatazy, fruktozo-1,6-difosfatazy, fosforylazy, karboksylazy pirogronianowej, fosfofosfoenolopirydokarboksylazy czy syntazy glikogenu)59
  • Guziczak (nesidioblastosis) – rozrost komórek trzustki wydzielających insulinę, który może być wrodzony lub nabyty, np. po operacji żołądka60
  • Celowe wywołanie hipoglikemii (hipoglikemia fikcyjna) poprzez podawanie insuliny lub pochodnych sulfonylomocznika u osób bez wskazań medycznych61

Hipoglikemia u dzieci

Hipoglikemia u dzieci może mieć inne przyczyny niż u dorosłych62:

  • U noworodków hipoglikemia może wynikać z nadmiernej produkcji insuliny przez matkę z cukrzycą, stresu okołoporodowego lub urazów63
  • Ketotyczna hipoglikemia – najczęstsza przyczyna hipoglikemii u zdrowych dzieci w wieku 1-5 lat, związana z ograniczoną zdolnością do wykorzystania zapasów energii w warunkach głodzenia64
  • Wrodzone zaburzenia metaboliczne, takie jak choroba spichrzania glikogenu, zaburzenia oksydacji kwasów tłuszczowych, zaburzenia ketogenezy i glukoneogenezy65

Mechanizmy rozwoju hipoglikemii

Hipoglikemia rozwija się, gdy tempo usuwania glukozy z krwi przewyższa tempo jej dodawania66. Można wyróżnić dwa główne mechanizmy patofizjologiczne:

Hipoglikemia hiperinsulinemiczna

Jest to najczęstszy mechanizm hipoglikemii, charakteryzujący się względnym lub bezwzględnym nadmiarem insuliny67. Mechanizmy prowadzące do hiperinsulinemicznej hipoglikemii obejmują:

  • Egzogenną insulinę podawaną w leczeniu cukrzycy lub przypadkowo/celowo przez osoby bez cukrzycy68
  • Endogenną nadmierną produkcję insuliny przez guz insulinoma69
  • Nadmierną produkcję insuliny przez rozrośnięte komórki wysp trzustkowych (nesidioblastosis)70
  • Autoimmunologiczną hipoglikemię związaną z przeciwciałami przeciwko insulinie lub receptorom insulinowym71

Hipoglikemia hipoinsulinemiczna

Ten typ hipoglikemii rozwija się niezależnie od insuliny; w powiązanych stanach poziom insuliny we krwi jest odpowiednio niski podczas hipoglikemii72. Mechanizmy obejmują:

  • Niewystarczającą produkcję glukozy przez wątrobę z powodu choroby wątroby, niedożywienia lub zaburzeń metabolicznych73
  • Niedobory hormonów przeciwregulacyjnych (kortyzol, glukagon, hormon wzrostu), które normalnie podnoszą poziom glukozy74
  • Guzy wydzielające substancje insulinopodobne, które promują hipoglikemię75
  • Zwiększony metabolizm glukozy spowodowany przez ciężkie infekcje lub stany zapalne76

Zrozumienie etiologii hipoglikemii jest kluczowe dla odpowiedniego leczenia i zapobiegania jej potencjalnie poważnym konsekwencjom. Prawidłowa diagnoza przyczyny hipoglikemii pozwala na ukierunkowane działania terapeutyczne, które mogą prowadzić do całkowitego wyleczenia w przypadku niektórych odwracalnych przyczyn.

    https://www.medparkhospital.com/en-US/disease-and-treatment/hypoglycemia
    Hypoglycemia develops when the level of blood glucose drops below 70 milligrams per deciliter (mg/dL) or 3.9 millimoles per liter (mmol/L) in diabetic people and below 55 mg/dL or 3.1 mmol/L for non-diabetics. […] For people with diabetes, these circumstances can lead to hypoglycemia. […] For people without diabetes, Non-diabetes-related hypoglycemia is of two types: reactive hypoglycemia and fasting hypoglycemia. […] Reactive hypoglycemia typically occurs approximately 2 – 4 hours after eating a meal of simple carbohydrates, which are rapidly broken down and absorbed, such as white rice, potatoes, white bread, cake, and pastries. […] Fasting hypoglycemia. Usually, the body has glucose storage as glycogen, so fasting does not cause hypoglycemia. Under certain circumstances fasting can lead to hypoglycemia as follows:

    Blood sugar, or glucose, is the main source of energy for both the body and the brain. Low levels of blood glucose, called hypoglycemia, will deprive the body and brain of energy, resulting in unconsciousness. If left untreated, it can lead to death. […] Hypoglycemia is the most common side effect of insulin administration for the treatment of diabetes. […] Cats under treatment for diabetes are at a higher risk for developing hypoglycemia. Mistakes that can be made when administering insulin include: […] Other causes of hypoglycemia in cats that are unrelated to the administration of insulin for diabetic patients include:
  • #3 Hypoglycemia – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK534841/
    In patients who do not have diabetes, hypoglycemia is uncommon. Still, when it occurs, there are a few major causes of hypoglycemia: pharmacologic, alcohol, critical illness, counter-regulatory hormone deficiencies, and non-islet cell tumors. […] Most hypoglycemia cases occur in patients with diabetes who are undergoing therapeutic intervention with meglitinides, sulfonylureas, or insulin. Drugs are the most common cause of hypoglycemia. […] Other potential causes of hypoglycemia are critical illness, alcohol, cortisol deficiency, or malnourishment. […] Alcohol inhibits gluconeogenesis in the body but does not affect glycogenolysis. Thus, hypoglycemia occurs after several days of alcohol consumption and after glycogen stores are depleted. […] For example, in critical illness states, end-stage liver disease, sepsis, starvation, or renal failure, glucose utilization exceeds glucose intake, glycogenolysis, or gluconeogenesis. This imbalance can potentially cause hypoglycemia.
  • #4 Hypoglycemia – Wikipedia
    https://en.wikipedia.org/wiki/Hypoglycemia
    Hypoglycemia is most common in those with diabetes treated by insulin, glinides, and sulfonylureas. […] The most common cause of hypoglycemia is medications used to treat diabetes such as insulin, sulfonylureas, and biguanides. […] Other causes of hypoglycemia include severe illness, sepsis, kidney failure, liver disease, hormone deficiency, tumors such as insulinomas or non-B cell tumors, inborn errors of metabolism, and several medications. […] Hypoglycemia is rare in those without diabetes, because there are many regulatory mechanisms in place to appropriately balance glucose, insulin, and glucagon. […] Other causes of hypoglycemia in diabetics include fasting, exercising more than usual, drinking alcohol, and kidney disease. […] Serious illness may result in low blood sugar. […] Sepsis, a common cause of hypoglycemia in serious illness, can lead to hypoglycemia through many ways.

    https://www.merckmanuals.com/professional/endocrine-and-metabolic-disorders/diabetes-mellitus-and-disorders-of-carbohydrate-metabolism/hypoglycemia
    Hypoglycemia in patients without diabetes is rare. It can occur in the fasting or in the postprandial state (1 to 3 hours after eating) and can be classified as insulin-mediated or non-insulin-mediated. […] Insulin-mediated causes include exogenous insulin, insulin secretagogue (sulfonylurea; eg, glyburide, glipizide, glimepiride) use, insulinoma, post-bariatric surgery hypoglycemia, non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS), and insulin autoimmune hypoglycemia. […] Non-insulin-mediated causes include adrenal insufficiency and the use of medications other than insulin or a sulfonylurea (eg, quinine, gatifloxicin, pentamidine, alcohol). […] In patients who are ill and hospitalized, spontaneous hypoglycemia that is not caused by medications can occur when poor nutrition is combined with advanced organ failure (especially liver, kidney, or heart failure) and/or sepsis. […] Non-islet cell tumor hypoglycemia is a rare condition caused by production of large amounts of aberrant forms of insulin-like growth factor 2 (IGF-2) by a tumor. […] Factitious hypoglycemia is true hypoglycemia induced by nontherapeutic administration of sulfonylureas or insulin.
  • #6 Drug-induced low blood sugar: MedlinePlus Medical EncyclopediaLock
    https://medlineplus.gov/ency/article/000310.htm
    Drug-induced low blood sugar is low blood glucose that results from taking medicine. […] Low blood sugar (hypoglycemia) is common in people with diabetes who are taking insulin or other medicines to control their diabetes. […] Other than certain medicines, the following can also cause blood sugar (glucose) level to drop: Drinking alcohol, Getting more activity than usual, Intentionally or unintentionally overdosing on the medicines used to treat diabetes, Missing meals. […] Even when diabetes is managed very carefully, the medicines used to treat diabetes can result in drug-induced low blood sugar. […] The condition may also occur when someone without diabetes takes a medicine used to treat diabetes. […] In rare cases, non-diabetes-related medicines can cause low blood sugar. […] Medicines that can cause drug-induced low blood sugar include: Beta-blockers (such as atenolol, or propranolol overdose), Cibenzoline and quinidine (heart arrhythmia drugs), Glinides (such as nateglinide and repaglinide), Indomethacin (a pain reliever), Insulin, Metformin when used with sulfonylureas, SGLT2 inhibitors (such as canagliflozin, dapagliflozin, empagliflozin and ertugliflozin) with or without sulfonylureas, Sulfonylureas (such as glipizide, glimepiride, glyburide), Thiazolidinediones (such as pioglitazone and rosiglitazone) when used with sulfonylureas, Drugs that fight infections (such as gatifloxacin, levofloxacin, pentamidine, quinine, trimethoprim-sulfamethoxazole).
  • #7 Hypoglycemia (Low Blood Sugar): Symptoms & Treatment
    https://my.clevelandclinic.org/health/diseases/11647-hypoglycemia-low-blood-sugar
    Hypoglycemia happens when your blood sugar drops below a healthy range. Several factors can contribute to this for people with diabetes. Hypoglycemia can develop if things like food, exercise and diabetes medications are out of balance. […] Common situations that can lead to hypoglycemia for people with diabetes include: Taking too much insulin, the wrong insulin or injecting it into your muscle instead of in your fat tissue. […] What causes hypoglycemia in people without diabetes? There are two main types of non-diabetes-related hypoglycemia: reactive hypoglycemia and fasting hypoglycemia. […] Reactive hypoglycemia happens when you experience low blood sugar after a meal. It typically occurs about two to four hours after a meal. […] Researchers dont yet know the exact cause. But they think it happens due to a sudden spike and then fall in blood sugar after eating certain foods, especially simple carbohydrate foods like white rice, potatoes, white bread, cake and pastries.

  • #9 Diabetic hypoglycemia – Symptoms & causes – Mayo Clinic
    https://www.mayoclinic.org/diseases-conditions/diabetic-hypoglycemia/symptoms-causes/syc-20371525
    Diabetic hypoglycemia occurs when someone with diabetes doesn’t have enough sugar (glucose) in his or her blood. […] Low blood sugar is most common among people who take insulin, but it can also occur if you’re taking certain oral diabetes medications. […] Common causes of diabetic hypoglycemia include: Taking too much insulin or diabetes medication, Not eating enough, Postponing or skipping a meal or snack, Increasing exercise or physical activity without eating more or adjusting your medications, Drinking alcohol. […] If you have type 1 or type 2 diabetes and need insulin to control your blood sugar, taking more insulin than you need can cause your blood sugar level to drop too low and result in hypoglycemia. […] Your blood sugar can also drop too low if, after taking your diabetes medication, you eat less than usual, or if you exercise more than you typically do, which uses extra glucose.
  • #10 Causes and How to Prevent Hypoglycemia (Low Blood Glucose) | American Diabetes Association
    https://diabetes.org/living-with-diabetes/hypoglycemia-low-blood-glucose/causes-prevention
    Hypoglycemia (or low blood glucose) is common for people with type 1 diabetes. It also can occur in people with type 2 diabetes taking insulin or certain diabetes medications. […] Too much insulin or certain diabetes medications is a common cause of low blood glucose. Miscalculating for how many carbs you’ve eating can lead to giving too much insulin, resulting in a low. […] What you eat or drink can has a big impact on your glucose levels. Sometimes, it can lead to a low when the following occurs. […] Physical activity and exercise can lower your blood glucose. Also, more intense physical activity or exercise than usual can make your body more sensitive to insulin and lower your blood glucose levels after you’re done. […] Your best bet is to keep your blood glucose in your target range. Keep track of your personal symptoms you feel when go low. If you start to recognize those feelings, you can act faster to treat your low glucose before it drops lower. […] The average person with type 1 diabetes has low blood glucose levels up to twice a week. Learn what causes and lows and what you can do to prevent them.
  • #11 Hypoglycemia and Diabetes (for Parents) | Nemours KidsHealth
    https://kidshealth.org/en/parents/hypoglycemia.html
    When blood glucose levels (called blood sugar levels) drop too low, it’s called hypoglycemia. […] Hypoglycemia can happen for different reasons. Anyone with diabetes can get low blood sugar, even people who follow their care plan carefully. Sugar levels can drop if your child: […] skips or delays meals or snacks or doesn’t eat as much carbohydrate-containing food as expected when taking their diabetes medicine. This happens often in kids who develop an illness (such as a stomach virus) that causes loss of appetite, nausea, or vomiting. […] takes too much insulin, takes the wrong type of insulin, or takes insulin at the wrong time […] exercises more than usual without eating extra snacks or adjusting the dosage of diabetes medicines.
  • #12 Avoiding Nighttime Hypoglycemia | Joslin Diabetes Center
    https://joslin.org/news-stories/all-news-stories/education/2020/03/avoiding-nighttime-hypoglycemia
    Nighttime hypoglycemia can be the result of a number of factors in people with diabetes. It is important to learn what causes hypoglycemia (low glucose) in order to prevent it from happening. […] Having an active day or exercising close to bedtime with diabetes can lower glucose and cause hypoglycemic during sleep or overnight. Other factors that can put you at risk for nighttime hypoglycemia are too much basal (background) insulin or consuming alcohol in the evening. While your liver is busy clearing the alcohol from your blood it stops producing glucose putting one at risk for having a lower glucose level. […] Some people forget that their premeal (fast-acting) insulin can last for up to five to six hours. If you eat a late dinner and go to sleep a few hours later, your glucose may be okay before going to bed. However, since the insulin you took for dinner is still working in your body, your glucose could drop during the night.
  • #13 Low blood sugar (hypoglycaemia)
    https://www.nhs.uk/conditions/low-blood-sugar-hypoglycaemia/
    Low blood sugar usually affects people with diabetes who take insulin or some other diabetes medicines. It’s rare in people without diabetes. […] Diabetes causes high blood sugar (hyperglycaemia). Diabetes medicines treat your condition by lowering your blood sugar, but they can sometimes make it go too low. […] You’re more likely to get low blood sugar if you: take too much insulin; have problems with the way you inject insulin, such as injecting in the same place too often; miss or delay meals, or do not eat enough carbohydrate; do a lot of exercise without eating more carbohydrate or reducing your insulin dose; drink a lot of alcohol, particularly without eating. […] It’s rare to get low blood sugar if you do not have diabetes. It can sometimes be caused by conditions including: malnutrition; Addison’s disease; a growth (tumour) in your pancreas.

    Inborn errors of metabolism may cause infant hypoglycemia, and much less commonly adult hypoglycemia. […] A primary B-cell tumor, such as an insulinoma, is associated with hypoglycemia. […] Hypoglycemia may occur in people with non-B cell tumors such as hepatomas, adrenocorticoid carcinomas, and carcinoid tumors. […] The Roux-en-Y gastric bypass has been associated with hypoglycemia, called post-gastric bypass postprandial hypoglycemia.

    Hypoglycemia in patients without diabetes is rare. It can occur in the fasting or in the postprandial state (1 to 3 hours after eating) and can be classified as insulin-mediated or non-insulin-mediated. […] Insulin-mediated causes include exogenous insulin, insulin secretagogue (sulfonylurea; eg, glyburide, glipizide, glimepiride) use, insulinoma, post-bariatric surgery hypoglycemia, non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS), and insulin autoimmune hypoglycemia. […] Non-insulin-mediated causes include adrenal insufficiency and the use of medications other than insulin or a sulfonylurea (eg, quinine, gatifloxicin, pentamidine, alcohol). […] In patients who are ill and hospitalized, spontaneous hypoglycemia that is not caused by medications can occur when poor nutrition is combined with advanced organ failure (especially liver, kidney, or heart failure) and/or sepsis. […] Non-islet cell tumor hypoglycemia is a rare condition caused by production of large amounts of aberrant forms of insulin-like growth factor 2 (IGF-2) by a tumor. […] Factitious hypoglycemia is true hypoglycemia induced by nontherapeutic administration of sulfonylureas or insulin.

    Hypoglycemia is a common problem with an increasing incidence in critically ill or extremely low birthweight infants. Its potential association with brain damage and neurodevelopment delay make it an important topic. If not due to maternal hyperglycemia, in most cases it is multifactorial, transient and easily supported. In a minority of cases, hypoglycemia turns out to be due to significant hyperinsulinism, hypopituitarism or an inborn error of metabolism and presents more of a management challenge. […] Single episodes of hypoglycemia may occur due to gastroenteritis or fasting, but recurrent episodes nearly always indicate either an inborn error of metabolism, congenital hypopituitarism, or congenital hyperinsulinism. […] By far, the most common cause of severe hypoglycemia in this age range is insulin injected for type 1 diabetes. […] The incidence of hypoglycemia due to complex drug interactions, especially involving oral hypoglycemic agents and insulin for diabetes, rises with age. Though much rarer, the incidence of insulin-producing tumors also rises with advancing age.

    Ketotic hypoglycemia is the most common cause of low blood sugar in an otherwise healthy toddler or young child, however a few children may have a more serious condition. […] The cause of ketotic hypoglycemia in most children is unknown. Children with ketotic hypoglycemia have two problems: (1) they tend to use up energy stored in the liver and switch to making ketones for energy sooner than other children, and (2) they are sometimes unable to use stored fat and muscle energy effectively to keep their blood sugar up. These problems usually improve as children get older and become more grown up in the way they store and use fuels like carbohydrate and fat.

    Hypoglycemia in children will also be briefly reviewed. In children, hypoglycemia is mostly due to inborn errors of metabolism (IEM) and is associated with multisystem involvement. […] There are many causes of non-diabetic hypoglycemia. […] Hypoglycemia caused by drugs is very common. Many drugs other than anti-hyperglycemic medications and alcohol have been reported. […] In children, hypoglycemia is mainly secondary to IEM. It includes glycogen storage disease, fatty acid oxidation defect, ketogenesis defects, and gluconeogenesis disorders. […] Hypoglycemia occurs due to impaired glucose regulation by the liver. […] Hypoglycemia can occur due to corticotropic and somatotropic hormone deficiency. […] The cause of hypoglycemia can be multifactorial and varies with the type of drug. […] Hypoglycemia occurs in the postprandial phase. The mechanism is likely due to an altered rate of digestion and secretion of insulin.

    Hypoglycemia is a manifestation of a pathologic process not a diagnosis. It is always secondary to a disorder that disrupts or overwhelms one or more of the homeostatic mechanisms responsible for maintenance of normoglycemia. […] Hypoglycemia occurs when the rate of glucose removal exceeds the rate of its addition to blood. Endogenous or exogenous substances that mimic or potentiate insulin action or enhance or accelerate glucose metabolism increase glucose removal, whereas failure of endogenous glucose production decreases the rate of glucose addition to blood. Disruptions of the pathways responsible for glucose addition or removal may overwhelm homeostatic mechanisms and produce clinical hypoglycemia. […] Hypoglycemia has been associated with a variety of clinical conditions but is a consistent feature of relatively few disorders.

    Clinical disorders produce hypoglycemia through one or more pathophysiologic mechanisms. Clinical hypoglycemia can be broadly divided into several categories: hyperinsulinemic hypoglycemia, hypoinsulinemic hypoglycemia, and miscellaneous disorders. […] Hyperinsulinemic hypoglycemia is the most common mechanism of hypoglycemia in dogs and cats, with relative or absolute insulin excess being a common feature. […] Hypoinsulinemic hypoglycemia describes hypoglycemia that develops independent of insulin; in associated conditions, blood insulin is appropriately low with hypoglycemia. Non-insulin-mediated hypoglycemia may develop via one of several mechanisms. Several tumor types produce humoral insulin-like substances that promote hypoglycemia. […] Hypoglycemia secondary to liver failure subsequent to cirrhosis or other disorders carries a poor prognosis, whereas hypoglycemia in patients with portovascular anomaly is expected to resolve after shunt closure.

    PPH is a well-known late complication of upper gastrointestinal surgery. […] Its exact incidence is unknown; one study reported 9.1% and 7.9% incidence at 1 and 5 years, respectively, post-RYGB surgery. […] A mutation in INSR (insulin receptor kinase) gene leading to impaired insulin clearance and insulin resistance, results in PPH with onset in adolescence to adulthood. […] This disorder develops due to aldolase B deficiency. […] Exogenous hyperinsulinemia causing PPH, due to surreptitious administration of insulin or insulin secretagogues such as sulfonylureas and meglitinides, is usually seen in people who have access to these medications.

    In patients who do not have diabetes, hypoglycemia is uncommon. Still, when it occurs, there are a few major causes of hypoglycemia: pharmacologic, alcohol, critical illness, counter-regulatory hormone deficiencies, and non-islet cell tumors. […] Most hypoglycemia cases occur in patients with diabetes who are undergoing therapeutic intervention with meglitinides, sulfonylureas, or insulin. Drugs are the most common cause of hypoglycemia. […] Other potential causes of hypoglycemia are critical illness, alcohol, cortisol deficiency, or malnourishment. […] Alcohol inhibits gluconeogenesis in the body but does not affect glycogenolysis. Thus, hypoglycemia occurs after several days of alcohol consumption and after glycogen stores are depleted. […] For example, in critical illness states, end-stage liver disease, sepsis, starvation, or renal failure, glucose utilization exceeds glucose intake, glycogenolysis, or gluconeogenesis. This imbalance can potentially cause hypoglycemia.
