Bulimia nerwicowa nieograniczona
Etiologia i przyczyny

Bulimia nerwicowa nieograniczona (BED) to złożone zaburzenie psychiczne o wieloczynnikowej etiologii, w której kluczową rolę odgrywają czynniki genetyczne (dziedziczność 41-57%), neurobiologiczne (dysfunkcja układu nagrody, zmieniona aktywność dopaminy, serotoniny i endogennych peptydów opioidowych), hormonalne (zaburzenia greliny, leptyny, oksytocyny oraz hormonów podwzgórzowych) oraz zmiany w mikrobiocie jelitowej. Neuroobrazowanie (fMRI) wykazuje zmiany w strukturze i funkcjonowaniu mózgu, szczególnie w obszarach odpowiedzialnych za kontrolę impulsów i regulację apetytu. Czynniki psychologiczne, takie jak współwystępowanie zaburzeń depresyjnych, lękowych, ADHD, niska samoocena, perfekcjonizm oraz trudności w regulacji emocji, znacząco wpływają na rozwój BED. Istotnym czynnikiem ryzyka jest historia restrykcyjnych diet i ograniczania jedzenia, które prowadzą do biologicznej reakcji zwiększonego apetytu i tworzą błędne koło „dieta-objadanie”. Traumatyczne doświadczenia, w tym przemoc fizyczna, seksualna, zaniedbanie i dręczenie, również mają istotny wpływ na patogenezę zaburzenia.

Etiologia Bulimii Nerwicowej Nieograniczonej

Bulimia nerwicowa nieograniczona (zaburzenie z napadami objadania się, ang. Binge Eating Disorder, BED) to złożone zaburzenie psychiczne, którego etiologia jest wieloczynnikowa. Nie istnieje pojedyncza, jednoznaczna przyczyna rozwoju tego zaburzenia, a raczej złożona interakcja czynników biologicznych, psychologicznych, społecznych i środowiskowych123.

Czynniki genetyczne i biologiczne

Badania wykazują, że czynniki genetyczne odgrywają istotną rolę w rozwoju bulimii nerwicowej nieograniczonej. Szacuje się, że dziedziczność tego zaburzenia wynosi od 41% do 57%, co wskazuje na znaczącą komponentę genetyczną12. Osoby, których krewni pierwszego stopnia cierpią na zaburzenia odżywiania, mają znacznie wyższe ryzyko rozwoju BED1. Badania bliźniąt dodatkowo potwierdzają, że genetyczne czynniki istotnie przyczyniają się do wystąpienia tego zaburzenia1.

Na poziomie biologicznym zidentyfikowano kilka istotnych czynników ryzyka rozwoju BED:

  • Polimorfizmy genów wpływających na układ nagrody, w tym DRD2 i OPRM11
  • Polimorfizmy genów 5-HTT oraz MC4R (choć dowody są niejednoznaczne)1
  • Zmiany w mikrobiocie jelitowej12
  • Zwiększona wrażliwość na dopaminę w mózgu, odpowiedzialną za uczucie przyjemności i nagrody12
  • Zaburzenia w poziomie serotoniny, które mogą wpływać na regulację apetytu12
  • Nieregularności hormonalne, w tym zaburzenia hormonów głodu i sytości produkowanych w podwzgórzu12

Badania z wykorzystaniem funkcjonalnego rezonansu magnetycznego (fMRI) wykazały, że osoby z BED mają zmienioną strukturę i funkcjonowanie mózgu, szczególnie w obszarach odpowiedzialnych za kontrolę impulsów, odczuwanie przyjemności i regulację apetytu12. Te zmiany neurobiologiczne mogą prowadzić do zaburzeń w mechanizmach kontroli zachowań związanych z jedzeniem1.

Czynniki psychologiczne

Na rozwój BED istotnie wpływają również czynniki psychologiczne. Do najważniejszych należą:

  • Współwystępowanie innych zaburzeń psychicznych – około 79% przypadków BED współwystępuje z innymi zaburzeniami psychicznymi12
  • Depresja i zaburzenia lękowe, które często poprzedzają lub towarzyszą BED12
  • Zaburzenia afektywne i negatywne stany emocjonalne, które mogą być bezpośrednim wyzwalaczem napadów objadania się12
  • Niska samoocena i negatywna ocena własnego ciała12
  • Perfekcjonizm, który może prowadzić do nierealistycznych oczekiwań wobec siebie12
  • Trudności w regulacji emocji i świadomości emocjonalnej12
  • ADHD (zaburzenie uwagi z nadaktywnością), które zwiększa ryzyko rozwoju BED poprzez deficyt dopaminy12
  • Sztywność behawioralna i trudności z adaptacją do zmian1

Wiele osób z BED używa jedzenia jako mechanizmu radzenia sobie z trudnymi emocjami. Objadanie się może być próbą ucieczki od nieprzyjemnych uczuć, numowania emocjonalnego bólu lub sposobem kompensacji niezaspokojonych potrzeb12. Badania wskazują, że najczęstszym bezpośrednim wyzwalaczem epizodu objadania się są właśnie negatywne emocje1.

Rola diety i ograniczania jedzenia

Jednym z najsilniejszych i najlepiej udokumentowanych czynników ryzyka rozwoju bulimii nerwicowej nieograniczonej jest historia stosowania diet i ograniczania jedzenia12. Mechanizm ten działa wielotorowo:

  • Restrykcyjne diety i ograniczanie kalorii mogą wywołać biologiczną reakcję organizmu w postaci zwiększonego apetytu i pragnienia jedzenia12
  • Wykluczanie całych grup pokarmowych może prowadzić do intensywnych zachcianek na zakazane produkty1
  • Ograniczanie jedzenia zwiększa stres i zaburza naturalne mechanizmy głodu i sytości1
  • „Dieta-objadanie” tworzy błędne koło – po okresach ograniczania następują epizody niekontrolowanego jedzenia, które wywołują poczucie winy prowadzące do kolejnych ograniczeń1
  • Osoby z BED często mają długą historię stosowania diet, często sięgającą lat nastoletnich1

Badania sugerują, że to właśnie dieta i ograniczanie jedzenia mogą być „bramą” do rozwoju zaburzeń odżywiania u osób z predyspozycjami genetycznymi1. Wielu ekspertów uważa, że restrykcyjna dieta jest najsilniejszym pojedynczym czynnikiem ryzyka rozwoju zaburzeń odżywiania, w tym BED1.

Czynniki traumatyczne i rozwojowe

Doświadczenia traumatyczne odgrywają istotną rolę w patogenezie bulimii nerwicowej nieograniczonej. Badania wykazują związek między następującymi czynnikami a rozwojem BED:

  • Przeżycie przemocy fizycznej lub seksualnej12
  • Doświadczenie zaniedbania w dzieciństwie1
  • Bycie ofiarą dręczenia (bullying) lub zawstydzania z powodu wagi12
  • Konfliktowe relacje rodzinne i dysfunkcja w rodzinie1
  • Psychopatologia rodzicielska1
  • Stresujące wydarzenia życiowe12
  • Krytyka dotycząca wagi i wyglądu ze strony rodziny1

Badania wskazują, że do 60% osób z BED zgłasza, że dręczenie było znaczącym czynnikiem w rozwoju ich zaburzenia1. Szczególnie kobiety z BED doświadczały większej liczby negatywnych wydarzeń życiowych w roku poprzedzającym początek rozwoju zaburzenia1. Jak wskazują statystyki, do 35% kobiet i 16% mężczyzn z zaburzeniami odżywiania doświadczyło traumy seksualnej1.

Czynniki społeczno-kulturowe

Czynniki społeczne i kulturowe silnie wpływają na rozwój BED poprzez:

  • Presję społeczną dotyczącą szczupłości i określonej sylwetki ciała1
  • Przekaz medialny idealizujący określony typ sylwetki12
  • Stygmatyzację osób z nadwagą i otyłością1
  • Normalizację diet i odchudzania jako sposobu osiągnięcia idealnej sylwetki1
  • Presję społeczną dotyczącą osiągnięć i sukcesu1
  • Wpływ kultury na postrzeganie atrakcyjności i wartości osoby1

Badania pokazują, że media społecznościowe i tradycyjne mogą być istotnym czynnikiem w rozwoju zaburzeń obrazu ciała i zachowań związanych z BED1. Szczególnie narażone są osoby, które angażują się w częste porównania społeczne dotyczące wyglądu1.

Współwystępowanie z innymi zaburzeniami

Bulimia nerwicowa nieograniczona często współwystępuje z innymi zaburzeniami psychicznymi, co może dodatkowo komplikować obraz kliniczny i leczenie. Najczęściej współwystępujące zaburzenia to:

  • Zaburzenia depresyjne12
  • Zaburzenia lękowe, w tym fobie społeczne1
  • Zaburzenie obsesyjno-kompulsyjne (OCD)12
  • ADHD12
  • Zaburzenia z używaniem substancji psychoaktywnych12
  • Zaburzenie dysmorficzne ciała1
  • Zaburzenie stresowe pourazowe (PTSD)12
  • Zaburzenia osobowości z pogranicza1

Badania wskazują, że około 79% osób z BED ma co najmniej jedno współwystępujące zaburzenie psychiczne1, a około 80% osób zdiagnozowanych z BED ma inną diagnozę psychiatryczną1. Ta wysoka współchorobowość sugeruje wspólne mechanizmy patofizjologiczne i czynniki ryzyka1.

Mechanizmy neurobiologiczne bulimii nerwicowej nieograniczonej

Najnowsze badania wskazują na wyraźne neurobiologiczne podłoże bulimii nerwicowej nieograniczonej, co przejawia się w kilku kluczowych mechanizmach:

Dysfunkcja układu nagrody

Jednym z głównych mechanizmów leżących u podłoża BED jest dysfunkcja układu nagrody w mózgu1. Badania z wykorzystaniem funkcjonalnego rezonansu magnetycznego (fMRI) wykazały, że osoby z BED mają zmienioną aktywność w obszarach mózgu odpowiedzialnych za odczuwanie przyjemności i nagrody podczas oglądania obrazów jedzenia1.

Spożywanie pokarmu aktywuje receptory w ośrodku nagrody w mózgu, co prowadzi do uwalniania substancji chemicznych wywołujących przyjemność, takich jak dopamina i endogenne peptydy opioidowe1. Osoby z BED mogą mieć zwiększoną wrażliwość na dopaminę, co prowadzi do intensywniejszej reakcji przyjemności na jedzenie1.

Powtarzające się epizody objadania się mogą zmieniać strukturę mózgu i sposób funkcjonowania jego układu nagrody, co prowadzi do błędnego koła zachowań związanych z objadaniem się1.

Dysregulacja neuroprzekaźników

Istnieją dowody na to, że dysregulacja neuroprzekaźników może być istotnym czynnikiem w rozwoju BED:

  • Zaburzenia poziomu dopaminy w mózgu, kluczowego neuroprzekaźnika w układzie nagrody1
  • Nieprawidłowości w poziomach serotoniny, która odgrywa rolę w regulacji apetytu i nastroju1
  • Zaburzenia w endogennym układzie opioidowym, który również uczestniczy w procesach nagrody1

Badania wykazały związek między niskimi poziomami serotoniny a zachowaniami związanymi z objadaniem się1. Te zaburzenia neuroprzekaźnikowe mogą tłumaczyć, dlaczego osoby z BED mają trudności z kontrolowaniem impulsów związanych z jedzeniem1.

Dysregulacja hormonalna

Hormony odgrywają istotną rolę w regulacji apetytu i zachowań związanych z jedzeniem. U osób z BED zaobserwowano zaburzenia w działaniu kilku kluczowych hormonów:

  • Nieprawidłowości w funkcjonowaniu hormonów głodu i sytości produkowanych w podwzgórzu1
  • Zaburzenia w poziomach greliny, leptyny i oksytocyny, które uczestniczą w regulacji apetytu1
  • U kobiet, dominacja progesteronu może powodować zwiększenie apetytu, zwłaszcza w określonych fazach cyklu menstruacyjnego1

Te dysregulacje hormonalne mogą przyczyniać się do zaburzenia mechanizmów kontroli apetytu i sytości u osób z BED1.

Zmiany w mikrobiocie jelitowej

Coraz więcej dowodów wskazuje na związek między mikrobiotą jelitową a zaburzeniami odżywiania, w tym BED. Częste epizody objadania się mogą znacząco zmieniać skład mikrobioty jelitowej, co z kolei może wpływać na zachowania związane z jedzeniem1. Badania sugerują, że mikrobiota jelitowa może indukować zachcianki żywieniowe u gospodarza, co może przyczyniać się do epizodów objadania się1.

Osoby, które często objadają się węglowodanami i cukrami, mogą mieć mikrobiotę jelitową zdominowaną przez bakterie preferujące te składniki odżywcze. Te bakterie mogą następnie stymulować dalsze zachcianki na takie produkty, tworząc błędne koło1.

Model biopsychospołeczny bulimii nerwicowej nieograniczonej

Obecnie najbardziej kompleksowym modelem wyjaśniającym rozwój bulimii nerwicowej nieograniczonej jest model biopsychospołeczny, który uwzględnia wzajemne oddziaływanie czynników biologicznych, psychologicznych i społecznych12.

W tym modelu, genetyczna predyspozycja może zwiększać podatność na BED, ale dopiero w połączeniu z określonymi czynnikami psychologicznymi (takimi jak niska samoocena, perfekcjonizm czy trudności w regulacji emocji) i społecznymi (takimi jak presja kulturowa czy traumatyczne doświadczenia) prowadzi do rozwoju pełnoobjawowego zaburzenia12.

Model ten podkreśla, że żaden pojedynczy czynnik nie działa w izolacji – to właśnie specyficzna kombinacja różnych czynników ryzyka u danej osoby prowadzi do rozwoju BED1. Ten „idealny sztorm” czynników biologicznych, psychologicznych i społecznych tworzy warunki sprzyjające rozwojowi zaburzenia1.

Zrozumienie tej złożonej interakcji czynników jest kluczowe dla opracowania skutecznych strategii profilaktyki i leczenia bulimii nerwicowej nieograniczonej1.

Wnioski i implikacje kliniczne

Etiologia bulimii nerwicowej nieograniczonej jest złożona i wieloczynnikowa. Zrozumienie tej złożoności ma istotne implikacje kliniczne:

  • Leczenie powinno być kompleksowe i ukierunkowane na wiele aspektów zaburzenia – od biologicznych po psychospołeczne1
  • Należy odejść od stygmatyzującego postrzegania BED jako braku silnej woli czy samokontroli, a uznać je za poważne zaburzenie o podłożu neurobiologicznym1
  • Wczesna interwencja jest kluczowa dla skutecznego leczenia, ponieważ przewlekłe epizody objadania się mogą prowadzić do trwałych zmian w układzie nagrody w mózgu1
  • Zapobieganie i leczenie powinno uwzględniać modyfikację czynników ryzyka, takich jak restrykcyjne diety, negatywna ocena ciała czy trudności w regulacji emocji1

Badania nad etiologią BED wciąż trwają i nasze zrozumienie przyczyn tego zaburzenia stale się pogłębia1. Neuroobrazowaie i inne zaawansowane techniki badawcze mogą prowadzić do lepszego zrozumienia biologicznych podstaw bulimii nerwicowej nieograniczonej i rozwoju bardziej ukierunkowanych metod leczenia1.

Należy pamiętać, że bulimia nerwicowa nieograniczona jest poważnym zaburzeniem psychicznym, które może prowadzić do istotnych powikłań zdrowotnych, w tym otyłości, cukrzycy, chorób sercowo-naczyniowych i wielu innych problemów medycznych1. Dlatego też wczesne rozpoznanie i kompleksowe leczenie tego zaburzenia jest niezwykle istotne dla poprawy rokowania i jakości życia pacjentów.

    Binge eating disorder is one of the most common eating disorders in the United States. […] There are many causes of binge eating disorder, including genetics, emotional factors, mental health conditions, and social conditioning. […] There isn’t a single cause for binge eating disorder; it’s influenced by a mix of factors. Your genes, biology, societal pressures, and mental health issues all play a role. […] If you have a family history of eating disorders, you have a 41% to 57% higher risk of developing binge eating disorder. […] Emotional eating can spiral into binge eating due to chemicals called dopamine and serotonin. […] Binge eating disorder is linked to mental health conditions like depression, anxiety, and ADHD (attention deficit hyperactivity disorder). […] Bullying, body shaming, dieting and food restrictions, along with feelings of stress and shame, can all trigger the urge to binge eat.

    Binge eating disorder (BED) is a type of eating disorder that involves periods of excessive eating. This can cause health issues linked to diet, such as high cholesterol levels and diabetes. […] A combination of biological, social, cultural, and environmental factors may cause them not just by exposure to diet culture. […] The causes of BED are not well understood, but a variety of risk factors include: Genetics: People with BED may have increased sensitivity to dopamine, a chemical in your brain that’s responsible for feelings of reward and pleasure. There is also strong evidence that the disorder is inherited. […] Emotional trauma: Stressful life events, such as abuse, death, or separation from a family member, are risk factors for eating disorders. Childhood bullying due to weight may also be a factor.

    There are also some health conditions or biological factors that may be involved in causing a binge-eating disorder. For example, changes in the hunger and satiety hormones produced in the hypothalamus can lead to an abnormal regulation of food intake and the possibility of binge-eating. […] Additionally, there is some evidence that the neurotransmitters in the brain such as serotonin may have a role to play, although more research is required to support this notion. […] Social and cultural ideals of beauty, body weight, and body shape may be driving factors for binge-eating disorder. Many individuals feel an overwhelming pressure to maintain a slender body shape and use strict dieting techniques get there. However, these restrictions can be counter-productive and increase the urge to eat when faced with emotional stress.

    https://www.wendyoliverpyatt.com/blog/what-are-the-possible-binge-eating-disorder-causes
    A very common misconception among patients and their families is that adults who suffer from Binge Eating Disorder just lack self-control or are greedy when it comes to food. These ideas couldnt be more wrong, and it is very important that patients with a Binge Eating Disorder diagnosis are reassured that their situation is caused by a medical disorder, and not a moral or personal failing, so that they may recognize that their condition is treatable. […] The exact cause of Binge Eating Disorder is unknown, and its possible there is more than one cause. However, a considerable and growing body of research points to a neurobiological dysfunction as the source of Binge Eating Disorder. […] The first possible Binge Eating Disorder cause is Impulse Reward Dysfunction. This hypothesis has been supported by studies that used functional magnetic resonance imaging (fMRI) to image the brains of volunteers, some with Binge Eating Disorder and others without Binge Eating Disorder, to compare how their brain activity differed when they viewed images of food as well as other, more neutral images.

    Eating anything will activate certain receptors in the brain’s reward center, sending feel-good chemicals, like dopamine and naturally occurring (endogenous) opioid peptides, through the body. […] Continuous episodes of binge eating behavior have been shown to change the structure of the brain and the way its reward system operates. […] The neurological response to certain foods can make binge eating episodes feel out of control, but binge eating is usually triggered in the first place by outside factors a person experiences in their everyday life. […] Studies have found that the same palatable foods that commonly trigger binging episodes can also effectively alleviate the psychological and physiological effects of stress. […] Studies have long tied frequent dieting to a higher risk of developing eating disorders, and the behavior seems to be particularly connected to developing binge eating disorder.

    Binge eating disorder involves periods of excessive overeating. It often occurs with mental health conditions like depression or anxiety. […] The BED cycle of eating can be a way of dealing with emotional problems and be a symptom of an underlying mental health condition. […] Overheating becomes a disorder when it occurs regularly, leads to feelings of shame, and affects daily life. Unlike eating for pleasure, BED often stems from an emotional or mental health or medical issue. […] It is more common in females than males and cooccurs with a mental health disorder in approximately 79% of cases. […] BED often stems from an underlying mental health problem. Conditions that commonly occur with binge eating include mood and anxiety disorders, major depressive disorder, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), alcohol or substance use disorder, and borderline personality disorder.

[…] Many people report that their disorder began with deliberate efforts to diet or restrict the amount and/or type of food they were eating. For example, a history of dieting and other weight-control methods is associated with the development of binge eating. […] Research has found that having difficulty regulating emotions or having a lack of emotional awareness is a risk factor for all types of eating disorders. […] Studies have found that a significant subset of people with eating disorders have experienced past trauma, such as physical, sexual, or emotional abuse and that childhood trauma can be a risk factor for the development of all types of eating disorders.

    https://my.clevelandclinic.org/health/diseases/17652-binge-eating-disorder
    Binge eating disorder (BED) is a behavioral disorder characterized by chronic, compulsive overeating. […] Environmental factors like stress and relationships can influence your behavior and affect your mental health. These factors may combine with other causes to push you over the edge from occasional disordered eating behavior to BED. […] Many factors influence eating behavior, including psychology, biology and learned habits. What triggers you to binge eat might be different from what triggers the next person. Eating can release pleasure hormones in your brain (serotonin and dopamine,) which might encourage addictive tendencies. Eating can also be a way of escaping or numbing uncomfortable feelings or compensating for unmet needs. […] You may be more likely to develop binge eating disorder if you have: A family pattern of disordered eating, A family pattern of dysfunctional emotional coping, A personal history of trauma or abuse, A personal history of food insecurity, A mental health condition, such as depression or anxiety, Attention-deficit/hyperactivity disorder (ADHD), Substance use disorder (SUD), Body dysmorphic disorder (BDD), Executive dysfunction.

    Perfectionism: Often, people with BED have a form of perfectionism known as self-oriented perfectionism. It involves creating unrealistically high and often unattainable expectations. […] Behavioral inflexibility: Like self-perfectionism, behavioral inflexibility is common with binge eating disorder. People with behavioral inflexibility are generally rule-followers, sometimes to a fault. […] Having an ideal appearance goal: A socially-defined ideal body can increase the risk of binge eating disorder. […] Teasing or bullying: Bullying has lasting impacts on young people. The harmful effects of teasing people about their weight cannot be understated. Some research suggests that up to 60% of people with BED report that bullying was a significant factor in developing an eating disorder. […] Lack of social circle: Those without a social circle often experience isolation and loneliness. This isolation can lead to feelings of depression, which may lead to binge eating.

    https://www.psychologytoday.com/us/conditions/binge-eating-disorder-compulsive-overeating
    Binge-eating disorder may be the most common eating disorder in the United States, where as many as 4 million adults struggle with it. […] The causes of binge-eating disorder are largely unknown. The disorder appears to run in families, which may reflect a genetic predisposition to developing eating disorders or a familial preoccupation with food or weight. […] Similarly, some experts suspect that psychological factors such as low self-esteem, poor body image, a penchant for yo-yo dieting, or stress can trigger or exacerbate episodes of binge eating. […] On a neurological level, the neurotransmitter dopamine is thought to play a role; some studies have found that people who engage in binge-eating behaviors may have abnormal levels of dopamine in their brains, though further research is needed to solidify this connection. […] The most common antecedent to an episode of binge-eating is negative emotion. Other triggers include interpersonal stressors, feeling hungry or restricted by an overly strict diet, negative feelings related to body image, and boredom.
  • #1 Azthena logo with the word Azthena
    https://www.news-medical.net/health/Binge-Eating-Disorder-Causes.aspx
    Poor body image and low self-esteem may also have a role to play in the development of binge-eating disorder. People who are dissatisfied with the appearance or shape of their body are more susceptible to an eating disorder such as binge-eating disorder. […] In particular, people who have a history of dieting with strict restriction of certain foods are more likely to be affected. Some patients with this condition report excessive dieting habits that began in childhood or early adolescent years. […] It is believed that the restricted eating patterns have the potential to trigger the urge to binge eat, particularly in combination with other risk factors, such as low-self esteem and stressful situations. Therefore, the craving or urge to eat the restricted food then leads to overeating and, if it happens repeatedly, the binge-eating disorder can present.

    Severe food restriction has also been found in some studies to bring on cravings for the exact kind of high-sugar, high-fat palatable foods that often trigger binge eating cycles. […] Extreme food restriction can also lead to irritability and other negative thoughts and emotions, which have been found in other studies to be a core factor in binge eating episodes.

    Binge Eating Disorder is often caused by a combination of biological, psychological, and environmental factors. There is rarely one singular cause or contributing factor. […] A history of weight fluctuation can place an individual at increased risk. Research also hints at a possible connection between binge eating disorder, hormone irregularities, and genetic mutations. A Journal of Psychiatric Research study revealed a link between low levels of serotonin and binge eating behavior. […] Many individuals with binge eating disorder report an extensive history of dieting, often dating back to their adolescent years. Dieting and the restriction of food can trigger hunger cues, often leaving one vulnerable to a binge. Furthermore, pressure to diet and maintain specific caloric intake can produce overwhelming feelings of stress, anxiety, and shame can often trigger a binge.
  • #1 Binge Eating Disorder: Causes and Risk Factors | Psych Central
    https://psychcentral.com/eating-disorders/binge-eating-disorder-causes
    Many social and cultural factors play a role in eating disorders. […] One of the major social forces that causes binge eating is weight loss dieting and food restriction. […] Our bodies are hardwired to want food when we go beneath a certain nutritional intake level. […] Because of this, expectations to diet, restrict certain food groups, or change the size and shape of our bodies can lead to feeling a loss of control when eating. […] The cultural idealization of thinness can, in and of itself, be a trigger for people with vulnerability for disordered eating and contribute to eating disorder behaviors. […] Some people grew up with just enough or not enough food due to their family’s low income, so these people binge eat because they’re conditioned to see food and eat it when it’s available.
  • #1 Causes of Eating Disorders
    https://www.ed.org.nz/eating-disorders-explained/causes/
    Unfortunately, we still don’t fully understand what causes eating disorders. […] However latest research is revealing that a combination of genes and environment are involved. […] It is now known that although cultural and environmental factors have an impact, genetics play a significant role. […] Studies have shown that 50-80% of the risk for developing an eating disorder comes from genetics. […] Specialists now recognise that in vulnerable individuals an eating disorder is usually triggered by a period of the body receiving inadequate nutrition. […] This nutritional deficit may be deliberate, or unintentional for example dieting, illness, certain medications, sports training as well as trauma can be enough to trigger a disorder in a person with a genetic predisposition. […] For vulnerable individuals dieting is the „gateway drug” to an eating disorder.

    Like most other mental health difficulties, there tends to be a combination of biological, psychological, social and environmental factors at play that come together to create the conditions where an eating disorder is more likely to develop. […] Risk factors associated with these illnesses include dieting and low self-esteem. […] In fact, dieting is the single most important risk factor for developing an eating disorder. […] Pre-disposing factors include: trauma, bullying, loss or grief, critical comments about weight or shape. […] Personality characteristics that can be associated with the development of an eating disorder include: anxiety, perfectionism, being obsessional, hyper-sensitivity, rigidity of thought. […] Genetics are also important. […] Current research indicates that there are significant genetic contributions to the development of eating disorders; for instance, first degree relatives of people with anorexia nervosa are ten times more likely to develop the illness in their lifetime.

This secrecy can fuel an eating disorder. While binge eaters tend to be overweight, they are often acutely aware of this and are critical of their own appearance. In fact, many report their own families were often critical and put pressure on them regarding their appearance starting at a young age. Parents stressing food as a comfort or a reward can unwittingly be one of the causes of overeating and binge eating disorder. […] One of the main causes of binge eating disorder is an inability to deal with, or control, the stresses in the world around the binge eater. The amount of food they eat is one thing they can control. It’s something that makes them feel good.
