Niedożywienie
Objawy

Niedożywienie to stan wynikający z niedostatecznego spożycia energii, makro- i mikroskładników odżywczych, prowadzący do zaburzeń funkcji wszystkich układów organizmu. Charakterystycznym objawem jest niezamierzona utrata masy ciała 5-10% w ciągu 3-6 miesięcy, choć możliwe jest także niedożywienie przy prawidłowej masie ciała lub nadwadze. Klinicznie obserwuje się zanik tkanki tłuszczowej i mięśniowej, zmiany skórne, osłabienie siły mięśniowej, obrzęki, zaburzenia gojenia ran oraz objawy metaboliczne, takie jak hipoglikemia (<3 mmol/l), hipotermia i zaburzenia elektrolitowe (niedobór potasu i magnezu). Niedożywienie osłabia układ odpornościowy, zwiększając ryzyko infekcji i powikłań, a także prowadzi do zaburzeń funkcji poznawczych i obniżenia jakości życia. U dzieci niedożywienie manifestuje się zahamowaniem wzrostu (stunting), niedowagą i wyniszczeniem (wasting), z ryzykiem rozwoju kwasziorkoru i marazmu, co wiąże się z wysoką śmiertelnością (5-60%).

Definicja i charakterystyka niedożywienia

Niedożywienie to stan, który występuje, gdy organizm nie otrzymuje odpowiedniej ilości lub właściwego balansu składników odżywczych niezbędnych do prawidłowego funkcjonowania. Niedożywienie może wynikać z niewystarczającego spożycia energii (kilokalorii), białka, tłuszczów, węglowodanów oraz mikroelementów (witamin i minerałów). Stan ten może prowadzić do poważnych konsekwencji zdrowotnych i ma istotny wpływ na funkcjonowanie wszystkich układów organizmu.123

Niedożywienie dotyka osoby w każdym wieku, jednak szczególnie narażone są dzieci poniżej 5 roku życia oraz osoby starsze. Częstość występowania niedożywienia wzrasta co najmniej dwukrotnie u osób starszych i pacjentów z chorobami przewlekłymi, a trzykrotnie u osób przebywających w placówkach opiekuńczych.456

Objawy niedoboru energii i makroskładników

Głównym objawem niedożywienia jest niezamierzony ubytek masy ciała, choć nie zawsze jest on oczywisty do zaobserwowania. Większość osób niedożywionych traci na wadze, jednak możliwe jest również utrzymanie prawidłowej masy ciała lub nawet nadwagi przy jednoczesnym niedożywieniu.789

O niedożywieniu może świadczyć niezamierzona utrata 5-10% masy ciała w ciągu 3-6 miesięcy. Inne objawy fizyczne niedożywienia obejmują:1011

  • Widoczny zanik tkanki tłuszczowej i masy mięśniowej
  • Szkieletowy wygląd, z widocznymi kośćmi
  • Głowa wydająca się zbyt duża w stosunku do ciała
  • Sucha, luźna skóra (zanik skóry)
  • Suche, łamliwe włosy lub wypadanie włosów
  • Zapadnięte ciemiączka u niemowląt
  • Obrzęki kończyn dolnych, a czasem także innych części ciała
  • Wzdęty brzuch (szczególnie u dzieci z kwasziorkorem)
  • Zmniejszenie obwodu ramienia
  • Osłabiona siła uścisku dłoni i ogólna siła mięśniowa
  • Problemy z gojeniem się ran
  • 121314

Progresja niedożywienia i jego wpływ na organizm

Niedożywienie rozwija się stopniowo i może przebiegać powoli lub bardzo szybko, jak ma to miejsce w przypadku szybko postępującej choroby nowotworowej. Gdy nie jest spożywana wystarczająca ilość kalorii, organizm najpierw rozkłada własną tkankę tłuszczową i wykorzystuje ją jako źródło energii. Po wyczerpaniu zapasów tłuszczu, organizm zaczyna rozkładać inne tkanki, takie jak mięśnie i narządy wewnętrzne, co prowadzi do poważnych problemów, w tym śmierci.1516

Przy braku makroskładników odżywczych (białka, węglowodanów, tłuszczów) organizm stopniowo zmniejsza swoje funkcje w celu oszczędzania energii. Jednym z pierwszych układów, który zaczyna się wyłączać, jest układ odpornościowy, co prowadzi do zwiększonego ryzyka infekcji i chorób.1718

W miarę postępu niedożywienia dochodzi do:1920

  • Zmniejszenia częstości akcji serca
  • Obniżenia ciśnienia tętniczego
  • Spadku temperatury ciała
  • Zaburzeń elektrolitowych
  • Zanikania układu pokarmowego i zmniejszenia jego funkcji
  • Osłabienia perystaltyki jelit
  • Kołatania serca, zawrotów głowy, bólów w klatce piersiowej (w ciężkim niedożywieniu)

U osób z umiarkowanym do ciężkiego niedożywienia może wystąpić osłabienie i ostatecznie utrata apetytu w miarę zaniku układu pokarmowego. Bez natychmiastowego leczenia ciężkie niedożywienie prowadzi do powikłań kardiologicznych i śmierci.2122

Zmiany w wyglądzie zewnętrznym

Niedożywienie powoduje charakterystyczne zmiany w wyglądzie zewnętrznym, które mogą być widoczne podczas badania fizykalnego:2324

  • Zmiany w jamie ustnej: zapalenie kątów ust (zajady), zapalenie warg, zanik brodawek języka
  • Zmiany skórne: sucha, łuszcząca się skóra z surowymi, odsłoniętymi obszarami; hiperpigmentowane blaszki nad obszarami urazów
  • Zmiany paznokci: popękane lub pobruzdowane paznokcie
  • Zmiany włosów: cienkie, rzadkie, łamliwe włosy, które łatwo wypadają i zmieniają kolor na matowy brązowy lub czerwonawy
  • Zmiany w jamie brzusznej: wzdęcie brzucha spowodowane osłabieniem mięśni brzucha i powiększeniem wątroby w wyniku stłuszczenia

Objawy funkcjonalne i metaboliczne

Niedożywienie powoduje szereg objawów funkcjonalnych, które wpływają na codzienne funkcjonowanie pacjenta i jakość życia:252627

  • Zmęczenie i brak energii
  • Osłabienie i szybsze męczenie się
  • Obniżona sprawność fizyczna (trudności w wykonywaniu codziennych czynności)
  • Zawroty głowy
  • Bóle stawów, bóle mięśniowe
  • Słaba koordynacja ruchowa
  • Trudności z utrzymaniem ciepła (uczucie zimna)
  • Osłabiony układ odpornościowy

Funkcja mięśni ulega pogorszeniu zanim pojawią się zmiany w masie mięśniowej, co sugeruje, że zmienione spożycie składników odżywczych ma istotny wpływ niezależnie od efektów utraty masy mięśniowej.28

Zaburzenia odpornościowe i infekcje

Niedożywienie znacząco osłabia układ odpornościowy, prowadząc do:293031

  • Częstszych infekcji i chorób
  • Przedłużonego czasu zdrowienia
  • Zwiększonej podatności na zakażenia oportunistyczne
  • Zmniejszonej produkcji komórek odpornościowych i przeciwciał
  • Wolniejszego gojenia się ran i urazów

W ciężkim niedożywieniu, typowe objawy infekcji bakteryjnej, takie jak gorączka, często nie występują, mimo że liczne zakażenia są powszechne.32

Zaburzenia gospodarki węglowodanowej i metabolizmu

Niedożywienie prowadzi do zaburzeń metabolicznych, które mogą objawiać się:3334

  • Hipoglikemią (obniżonym poziomem glukozy we krwi <3 mmol/l lub 54 mg/dl)
  • Hipotermią (obniżoną temperaturą ciała)
  • Zaburzeniami elektrolitowymi (szczególnie niedoborem potasu i magnezu)
  • Letargią, ospałością
  • Drgawkami (w ciężkich przypadkach)
  • Utratą przytomności

Wszyscy pacjenci z ciężkim niedożywieniem mają niedobory potasu i magnezu, których wyrównanie może trwać około 2 tygodni.35

Objawy psychologiczne i poznawcze

Niedożywienie wpływa na funkcje poznawcze i stan psychiczny pacjenta. Typowe objawy obejmują:363738

  • Apatię i zmniejszoną reaktywność społeczną
  • Drażliwość i zmiany nastroju
  • Niepokój i stany lękowe
  • Obniżony nastrój i depresję
  • Zaburzenia snu (bezsenność)
  • Problemy z koncentracją i uwagą
  • Zmniejszone zainteresowanie jedzeniem
  • Zaburzenia funkcji poznawczych (problemy z pamięcią, zmniejszoną czujność umysłową)
  • Dezorientację i splątanie (w ciężkich przypadkach)

Wpływ na samodzielność i funkcjonowanie społeczne

Niedożywienie może prowadzić do wycofania się z aktywności społecznych i zmniejszenia samodzielności:3940

  • Wycofanie z aktywności społecznych
  • Zmniejszone zainteresowanie zwykłymi hobby i aktywnościami
  • Trudności w wykonywaniu codziennych czynności
  • Utrata niezależności i autonomii
  • Obniżona jakość życia

Objawy niedożywienia u dzieci

Dzieci są szczególnie narażone na niedożywienie, które może prowadzić do poważnych i długotrwałych konsekwencji dla ich zdrowia i rozwoju. Objawy niedożywienia u dzieci obejmują:414243

  • Zatrzymanie wzrostu i rozwoju (niedobór wzrostu)
  • Nieprawidłowy przyrost masy ciała
  • Zmiany w zachowaniu (drażliwość, niepokój, apatia)
  • Niski poziom energii i szybsze męczenie się w porównaniu z innymi dziećmi
  • Opóźniony rozwój behawioralny i intelektualny
  • Trudności w nauce

U dzieci można wyróżnić trzy główne miary niedożywienia:4445

  • Zahamowanie wzrostu (stunting) – bardzo niski wzrost w stosunku do wieku
  • Niedowaga – bardzo niska waga w stosunku do wieku
  • Wyniszczenie (wasting) – bardzo niska waga w stosunku do wzrostu

Specyficzne syndromy niedożywienia u dzieci

U dzieci z ciężkim niedożywieniem mogą rozwinąć się specyficzne syndromy kliniczne:464748

  • Kwasziorkor – charakteryzuje się obrzękami kończyn dolnych, wzdętym brzuchem, suchą i łuszczącą się skórą oraz zmianami pigmentacji włosów; wynika z ciężkiego niedoboru białka
  • Marasmus – charakteryzuje się ciężkim wyniszczeniem z zanikiem tkanki tłuszczowej i mięśniowej, dając szkieletowy wygląd; wynika z ciężkiego niedoboru kalorii
  • Karłowatość pokarmowa – pacjent jest mały w stosunku do wieku z opóźnieniem wzrostu

Ciężkie niedożywienie u dzieci wiąże się ze śmiertelnością wynoszącą od 5% do 60%, w zależności od dostępności opieki medycznej.49

Niedożywienie a powikłania i progresja choroby

Niedożywienie wpływa na funkcję i regenerację każdego układu narządów, co ma istotny wpływ na wyniki kliniczne.50 Najważniejsze konsekwencje niedożywienia obejmują:

Powikłania kliniczne

  • Zwiększoną podatność na infekcje i choroby
  • Wydłużony czas gojenia się ran
  • Zwiększone ryzyko powikłań pooperacyjnych
  • Zmniejszoną odpowiedź na leczenie
  • Zwiększone ryzyko odleżyn
  • Zwiększone ryzyko upadków i złamań (szczególnie u osób starszych)
  • Niewydolność narządową (w ciężkich przypadkach)
  • Niewydolność serca, niewydolność oddechową i niewydolność wątroby (przy długotrwałym niedoborze kalorii)515253

Wpływ na rokowanie i przebieg chorób

Niedożywienie istotnie wpływa na przebieg i rokowanie chorób:5455

  • Pacjenci chirurgiczni z niedożywieniem mają 3-4 razy wyższe wskaźniki powikłań i śmiertelności
  • Dłuższy pobyt w szpitalu, zwiększający koszty o nawet 50%
  • Zwiększone ryzyko śmierci – niedożywienie bezpośrednio przyczynia się do wielu zgonów dzieci w krajach rozwijających się
  • Upośledzenie zdolności regeneracyjnych organizmu
  • Nasilenie objawów chorób podstawowych

Niedożywienie u pacjentów onkologicznych występuje z częstością 40-80% i wiąże się z obecnością objawów ograniczających przyjmowanie pokarmów (Nutrition Impact Symptoms – NIS), takich jak anoreksja, nudności, zaparcia, owrzodzenia jamy ustnej, zmieniony smak, wymioty, suchość w ustach, problemy z połykaniem i ból.5657

Niedożywienie w szczególnych grupach pacjentów

Osoby starsze

Niedożywienie i niska masa ciała są częstsze u osób starszych niż u dorosłych w innych grupach wiekowych. Jeśli osoby starsze są zdrowe i aktywne, sam proces starzenia zazwyczaj nie powoduje niedożywienia. Jednak zmiany w składzie ciała, funkcjach narządów, odpowiednim spożyciu energii oraz zdolności do jedzenia lub dostępu do żywności są związane ze starzeniem się i mogą przyczyniać się do niedożywienia.5859

Specyficzne czynniki przyczyniające się do niedożywienia u osób starszych:6061

  • Zmniejszony apetyt i utrata zainteresowania jedzeniem
  • Problemy z połykaniem i żuciem
  • Zmiany smaku i zapachu
  • Ograniczone dochody utrudniające dostęp do zdrowej żywności
  • Choroby przewlekłe zwiększające zapotrzebowanie na składniki odżywcze
  • Izolacja społeczna
  • Polipragmazja i interakcje leków
  • Obniżone tempo metabolizmu i zmniejszona aktywność fizyczna

Pacjenci z chorobami przewlekłymi

Niedożywienie często towarzyszy chorobom przewlekłym, wpływając na ich przebieg i rokowanie:626364

  • Choroby zapalne jelit: niedożywienie dotyka 65-75% pacjentów z chorobą Leśniowskiego-Crohna i 18-62% pacjentów z wrzodziejącym zapaleniem jelita grubego. Objawia się niedowagą, niedoborami pokarmowymi i zmianami w składzie ciała, niskim poziomem energii, ogólnym zmęczeniem i osłabieniem
  • Choroby nowotworowe: niedożywienie wpływa na skuteczność leczenia przeciwnowotworowego, siłę, regenerację i jakość życia. Zwiększa czas hospitalizacji i ryzyko infekcji
  • Marskość wątroby: niedożywienie występuje u około 20% pacjentów z wyrównaną marskością i 50% pacjentów z niewyrównaną marskością. Prowadzi do sarkopenii i zespołu kruchości, które wpływają na 30-70% pacjentów z końcowym stadium choroby wątroby
  • Otępienie: trudności w połykaniu, zmiany apetytu i zmiany nawiązów żywieniowych pojawiające się wraz z postępem otępienia mogą silnie wpływać na stan odżywienia

Typowe przyczyny niedożywienia w chorobach przewlekłych obejmują:65

  • Zmniejszone spożycie pokarmów z powodu nudności, bólu brzucha, wymiotów, biegunki
  • Zwiększone zużycie energii z powodu stanu zapalnego
  • Utratę składników odżywczych z powodu owrzodzeń lub biegunki
  • Zaburzenia wchłaniania (słabe wchłanianie składników odżywczych)
  • Wpływ leków, takich jak glikokortykosteroidy lub cholestyramina

Ocena i diagnostyka niedożywienia

Wczesne rozpoznanie niedożywienia jest kluczowe dla skutecznego leczenia. Diagnostyka obejmuje:6667

  • Badanie przedmiotowe: ocena masy ciała, BMI, obwodu ramienia, siły uścisku dłoni, obecności obrzęków
  • Wywiad medyczny: niezamierzona utrata masy ciała, zmiany apetytu, problemy z połykaniem, nudności, wymioty
  • Badania laboratoryjne: poziom białka, albumin, transferyny, elektrolitów, witamin i minerałów
  • Narzędzia przesiewowe: MNA (Mini Nutritional Assessment), SGA (Subjective Global Assessment), NRS-2002 (Nutritional Risk Screening)
  • Pomiar obwodu środkowej części ramienia (MUAC): prosty sposób identyfikacji niedożywienia, szczególnie u dzieci

U dzieci z ciężkim niedożywieniem należy przeprowadzić pełne badanie kliniczne, aby potwierdzić obecność ogólnych objawów zagrożenia, powikłań medycznych i ocenić apetyt.68

Podsumowanie progresji niedożywienia

Niedożywienie postępuje przez kilka etapów, od subtelnych zmian biochemicznych do wyraźnych objawów klinicznych:6970

  1. Zmiany w poziomie składników odżywczych we krwi i tkankach
  2. Zmiany wewnątrzkomórkowe w funkcjach biochemicznych i strukturze
  3. Pojawiają się objawy i oznaki kliniczne
  4. Rozwijają się powikłania narządowe
  5. Progresja do niewydolności narządowej i śmierci (w ciężkich przypadkach)

Całkowite głodzenie (gdy nie jest spożywany żaden pokarm) prowadzi do śmierci w ciągu 8-12 tygodni.71

Niedożywienie, jeśli nie jest leczone, może prowadzić do niepełnosprawności fizycznej lub psychicznej, chorób, a nawet śmierci. Wczesna identyfikacja objawów niedożywienia i odpowiednia interwencja są kluczowe dla optymalizacji wyników leczenia i zapobiegania długoterminowym konsekwencjom.7273

  • #1 Malnutrition: Definition, Causes, Symptoms & Treatment
    https://my.clevelandclinic.org/health/diseases/22987-malnutrition
    Malnutrition happens when the nutrients it gets dont meet these needs. […] Even the lack of a single vitamin or mineral can have serious health consequences for your body. […] Undernutrition is a deficiency of nutrients. […] Undernutrition can cause visible wasting of fat and muscle, but it can also be invisible. […] You can be overweight and undernourished. […] Micronutrient undernutrition can begin to have serious and lasting effects. […] Macronutrient undernutrition deprives your body of energy to sustain itself. […] To compensate, it begins breaking down its own tissues and shutting down its functions. […] One of the first systems to begin to shut down is the immune system. […] People with protein-energy undernutrition are often visibly emaciated. […] Children may have stunted growth and development.
  • #2 Malnutrition – UF Health
    https://ufhealth.org/conditions-and-treatments/malnutrition
    Malnutrition is the condition that occurs when your body does not get enough nutrients. […] Symptoms of malnutrition vary and depend on its cause. General symptoms include fatigue, dizziness, and weight loss. […] If untreated, malnutrition can lead to mental or physical disability, illness, and possibly death. […] Talk to your provider about the risk of malnutrition. Treatment is necessary if you or your child have any changes in the body’s ability to function. Contact your provider if these symptoms develop: Fainting, Lack of menstruation, Lack of growth in children, Rapid hair loss. […] Malnutrition is a significant problem all over the world, especially among children. It is very harmful to children because it affects brain development and other growth. Children who suffer from malnutrition may have lifelong problems.
  • #3 Malnutrition: causes and consequences
    https://pmc.ncbi.nlm.nih.gov/articles/PMC4951875/
    Malnutrition is a common, under-recognised and undertreated condition in hospital patients. […] Wide-ranging changes in physiological function occur in malnourished patients leading to increased rates of morbidity and mortality. […] The prevalence of malnutrition increases by at least twofold in the elderly and those with chronic disease, and threefold in individuals living in institutional care. […] Weight loss due to depletion of fat and muscle mass, including organ mass, is often the most obvious sign of malnutrition. […] Muscle function declines before changes in muscle mass occur, suggesting that altered nutrient intake has an important impact independent of the effects on muscle mass. […] Malnutrition affects the function and recovery of every organ system. […] The consequences of malnutrition on physiological function have an important impact on clinical outcome.

  • #5 Malnutrition | Dietitians Australia
    https://dietitiansaustralia.org.au/health-advice/malnutrition
    Malnutrition occurs when the bodys nutritional needs are not met. […] Malnutrition occurs over time if someone does not meet their nutritional needs. People become malnourished if they dont eat enough, or the right types of food, or if their body cant absorb all the nutrients from food. […] Malnutrition is linked with poor health. It can affect quality of life and lead to poor medical outcomes. […] Symptoms of malnutrition include: loss of appetite, weight loss, muscle wasting, hair loss, pale skin, fatigue or mental confusion, poor wound healing. […] Older people with malnutrition have a higher risk of falls, infection and pressure wounds. They may take a longer time to recover from illness or injury and can need more help with day-to-day tasks. […] Mandatory malnutrition screening, together with regular re-screening, is vital to ensure aged care providers can take action to reduce the progression of malnutrition.

    The main symptom of malnutrition (undernutrition) is unintentional weight loss, although this is not always obvious. […] Most people who are malnourished will lose weight, but it’s possible to be a healthy weight or even overweight and still be malnourished. […] You could be malnourished if: you unintentionally lose 5 to 10% of your body weight within 3 to 6 months. […] Other symptoms of malnutrition include: reduced appetite, lack of interest in food and drink, feeling tired all the time, feeling weaker, getting ill often and taking a long time to recover, wounds taking a long time to heal, poor concentration, feeling cold most of the time, low mood, sadness and depression. […] Symptoms of malnutrition in a child can include: not growing or putting on weight at the expected rate (faltering growth), changes in behaviour, such as being unusually irritable, slow or anxious, low energy levels and tiring more easily than other children.

  • #12 Marasmus: Definition, Symptoms & Causes
    https://my.clevelandclinic.org/health/diseases/23296-marasmus
    Children with chronic marasmus will not have the physical resources to grow and develop as they should. They may be stunted in size or have developmental delays or intellectual disabilities. These effects can be lasting, even in children who receive treatment. Parts of the digestive system also begin to atrophy from the lack of use. This means that even when people do have food to eat, they might not be able to absorb nutrition from their food effectively. Ironically, marasmus can lead to food aversion. […] What are the external signs of marasmus? Visible wasting of fat and muscle. Prominent skeleton. Head appears large for the body. Face may appear old and wizened. Dry, loose skin (skin atrophy). Dry, brittle hair or hair loss. Sunken fontanelles in infants. Lethargy, apathy and weakness. Weight loss of more than 40%. BMI below 16.
  • #13 Undernutrition – Disorders of Nutrition – Merck Manual Consumer Version
    https://www.merckmanuals.com/home/disorders-of-nutrition/undernutrition/undernutrition
    Undernutrition is a deficiency of calories or of one or more essential nutrients. […] Undernutrition is often obvious: People are underweight, bones often protrude, their skin is dry and inelastic, and their hair is dry and falls out easily. […] Undernutrition progresses in stages. It may develop slowly or very rapidly, as may occur when cancer is rapidly advancing. When not enough calories are consumed, the body first breaks down its own fat and uses it for calories much like burning the furniture to keep a house warm. After fat stores are used up, the body may break down its other tissues, such as muscle and tissues in internal organs, leading to serious problems, including death. […] The most obvious sign of a calorie deficiency is loss of body fat (adipose tissue). […] If people starve for about 1 month, they lose about one fourth of their body weight. If starvation continues for a long time, adults can lose up to half of their body weight, and children can lose even more.
  • #14 Malnutrition: Practice Essentials, Background, Pathophysiology
    https://emedicine.medscape.com/article/985140-overview
    Malnutrition is directly responsible for 300,000 deaths per year in children younger than 5 years in developing countries and contributes indirectly to more than half of all deaths in children worldwide. […] The most common and clinically significant micronutrient deficiencies and their consequences include the following: Iron: Fatigue, anemia, decreased cognitive function, headache, glossitis, and nail changes. […] Physical findings that are associated with protein-energy malnutrition (PEM) include the following: Decreased subcutaneous tissue: Areas that are most affected are the legs, arms, buttocks, and face. Edema: Areas that are most affected are the distal extremities and anasarca (generalized edema). Oral changes: Cheilosis, angular stomatitis, and papillar atrophy. Abdominal findings: Abdominal distention secondary to poor abdominal musculature and hepatomegaly secondary to fatty infiltration. Skin changes: Dry, peeling skin with raw, exposed areas; hyperpigmented plaques over areas of trauma. Nail changes: Fissured or ridged nails. Hair changes: Thin, sparse, brittle hair that is easily pulled out and that turns a dull brown or reddish color.

    Malnutrition happens when the nutrients it gets dont meet these needs. […] Even the lack of a single vitamin or mineral can have serious health consequences for your body. […] Undernutrition is a deficiency of nutrients. […] Undernutrition can cause visible wasting of fat and muscle, but it can also be invisible. […] You can be overweight and undernourished. […] Micronutrient undernutrition can begin to have serious and lasting effects. […] Macronutrient undernutrition deprives your body of energy to sustain itself. […] To compensate, it begins breaking down its own tissues and shutting down its functions. […] One of the first systems to begin to shut down is the immune system. […] People with protein-energy undernutrition are often visibly emaciated. […] Children may have stunted growth and development.

    Malnutrition occurs from a lack of food or from eating a poor diet. A child is either not getting enough nutrients (undernutrition) or they are eating more than they really need (overnutrition). The symptoms of malnutrition in children may include: lack of interest in food or drink, tiredness and irritability, feeling cold all of the time, gets sick more often and longer recovery, lack of growth, behavioural and intellectual development is slow, learning difficulties. The three commonly used measures for detecting malnutrition are: Stunting where the child has an extremely low height for their age, Underweight their weight is extremely low for their age, Wasting extremely low weight for their height. Children with severe malnutrition are extremely thin but tend to have swollen hands, feet and stomach and they are very susceptible to infection. In the UK, where malnutrition in children is often the result of a long-term health condition, hospital treatment is often required. The child’s height and weight will regularly need to be monitored to make sure that their treatment plan with the dietician is working.

    Wasting is defined as low weight-for-height. It often indicates recent and severe weight loss, although it can also persist for a long time. […] Stunting is defined as low height-for-age. It is the result of chronic or recurrent undernutrition, usually associated with poverty, poor maternal health and nutrition, frequent illness and/or inappropriate feeding and care in early life. Stunting prevents children from reaching their physical and cognitive potential. […] Micronutrient deficiencies are a lack of vitamins and minerals that are essential for body functions such as producing enzymes, hormones and other substances needed for growth and development. […] In 2018, stunting affected an estimated 21.9% or 149 million children under the age of 5 years, while wasting affected 7.3% or 49 million children under the age of 5 years. Around 45% of deaths among children under the age of 5 years are linked to undernutrition. […] Women, infants, children and adolescents are at the highest risk of malnutrition.

Malnutrition affects about 65% to 75% of people with Crohns disease and 18% to 62% of those with ulcerative colitis. IBD patients are often underweight, with nutritional deficiencies and changes in their body fat composition, muscle mass, and bone mineral density (which puts them at risk of fractures). They generally have low energy, general fatigue, and weakness. Malnutrition can lead to anemia: low red blood cells in the blood. This can cause fatigue and other problems. Malnutrition also makes it difficult to bounce back from an illness. […] The main reasons for malnutrition include inflammation, low nutrient intake, medications, and malabsorption (poor absorption of nutrients in the small intestine).

[…] People with cancer are at higher risk of malnutrition compared with the rest of the population. […] Early identification of the risk of malnutrition and early diagnosis of malnutrition is important so that it can be treated as soon as possible. […] A common type of malnutrition in people with cancer is under-nutrition. This is when the body gets less energy or essential nutrients (such as protein, fats and vitamins) than it needs. Under-nutrition causes the body to break down fat and muscle, leading to unplanned weight loss. […] If you have cancer, malnutrition can influence the effectiveness of your cancer treatment, your strength, recovery and quality of life. It can increase the time you spend in hospital and the risk of infection. Malnutrition also has the potential to reduce your life span.

    Undernutrition is a deficiency of calories or of one or more essential nutrients. […] Undernutrition is often obvious: People are underweight, bones often protrude, their skin is dry and inelastic, and their hair is dry and falls out easily. […] Undernutrition progresses in stages. It may develop slowly or very rapidly, as may occur when cancer is rapidly advancing. When not enough calories are consumed, the body first breaks down its own fat and uses it for calories much like burning the furniture to keep a house warm. After fat stores are used up, the body may break down its other tissues, such as muscle and tissues in internal organs, leading to serious problems, including death. […] The most obvious sign of a calorie deficiency is loss of body fat (adipose tissue). […] If people starve for about 1 month, they lose about one fourth of their body weight. If starvation continues for a long time, adults can lose up to half of their body weight, and children can lose even more.
