A person who has a binge eating disorder has a feeling of being out of control when it comes to eating. Food is ingested very quickly in large amounts. Binge eating differs from bulimia in that a person with a binge eating disorder does not purge themselves—by using laxatives or vomiting— after eating, as a person with bulimia does.
What Is Binge Eating Disorder?
Binge eating disorder is a serious but treatable condition that involves recurrent episodes of consuming large quantities of food.
In addition to eating food in excess and to the point of discomfort, the condition is also characterized by feeling out of control when eating and a sense of shame or guilt over the behavior.
Episodes of overeating that are classified as binge eating can significantly and negatively impact your health and well-being, making it especially important to identify the signs and symptoms of binge eating and get help if necessary.
According to the DSM-5, a person must binge at least once a week for three months before being a candidate for a formal diagnosis of BED. Other DSM-5 criteria for BED include:
Loss of control over the amount a person eatsDiscernible distress related to periods of binging
In addition to distress and loss of control, a person must have three or more of the following symptoms to be diagnosed with BED:
Experiencing fullness and continuing to eat until the level of discomfort is reachedEating very fast (faster than is considered normal; this could be described as “inhaling” one’s food)Feelings of depression, guilt, or self-loathing (disgust) about overeatingAvoidance of eating with others, preference to eat alone due to embarrassment linked with eating such large amounts of foodEating a large quantity of food (even when no physical feeling of hunger is present)
Statistics
BED is considered the most common type of eating disorder in the United States. In fact, according to the National Eating Disorders Association, BED is over three times more prevalent than anorexia and bulimia (combined).
One study found that 3.5% of women and 2% of men had binge eating disorder in their lifetime.
Although the majority of people diagnosed with obesity are not considered binge eaters, up to two-thirds of those with BED are obese.
Symptoms
There are a number of common signs and symptoms of a BED. A person with this type of disorder often:
Eats very large amounts of food in a short period of timeRefrains from being finished eating until they feel overly full and often uncomfortableEats to reduce stress and lower anxietyHas a track record of gaining and losing weightEats normal amounts of food around others, but often eats large amounts alone to hide symptomsEats continuously all day (without any type of planned mealtimes)Hoards food to eat later in secretExperiences trouble losing weight and keeping it off (Weight loss is often more difficult for a person who binge eats than people with other serious weight problems, such as those with obesity. )
Specific emotions linked with BED include:
Feeling self-disgust, guilt, and depression after binge eatingFeeling embarrassed about the amount of food they eatExperiencing stress or anxiety that is only alleviated by eatingFeeling numb while binge eatingFeeling desperate to control eating and lose weight
Risk Factors
It is thought that several combined factors help to increase the risk of having BED. These include a person’s:
Environmental factors (such as childhood experiences)GeneticsEmotionsBiological factors
Environmental Risk Factors
Several environmental factors are associated with the development of binge eating disorder. According to the National Eating Disorders Association, factors that may increase the risk of binge eating include:
Being an adolescent (mostly female)Being a young adult womanExperiencing social pressuresPursuing professions or activities that involve the need to be thinExperiencing pressure to dietNegative parental influencesFactors that impact a person’s self-worth or body image (such as media that portray very thin women)Being subjected to negative comments frequently (particularly comments about body image)Being bulliedSexual abuse
Note, although BED often impacts younger women and teens, it can occur at any age and also occurs in men.
Genetic Factors
Statistically, eating disorders do tend to have a familial link. Female relatives are more often impacted than males in the family. Because people who have a close family member with BED tend to have a higher risk of an eating disorder, it is believed that genetic factors are involved in the condition.
Emotional and Psychological Factors
Several predisposing factors exist for eating disorders, and in the instance of anorexia and bulimia, the research is quite clear. When it comes to BED, however, the disorder’s risk factors have not been as extensively researched, but there are some clues as to common personality factors that may predispose a person to BED. These include:
Low self-esteemFeelings of inadequacy and worthlessnessDepressionAnxietyA history of attention deficit hyperactivity disorder (ADHD)A history of depression or anxietyA history of unhappinessThe inability to cope with emotions or stressPoor body self-image
Other factors and emotions commonly linked with BED include:
Feeling hurtLonelinessSadnessDisappointmentProblems with impulse controlBody image issues (which is a common symptom for people with other eating disorders, such as anorexia)Difficulty managing emotionsTrouble effectively expressing feelings
Biological Factors
Biological factors that may increase the risk of BED include:
Hormonal irregularitiesLow levels of brain chemicals (such as serotonin)
Note, low serotonin levels are also linked with depression. According to a 2017 study, some people with BED respond well to medications that affect the function of serotonin in the body.
Behavioral Risks
Several behavioral risks may factor into predisposing a person to the development of BED. These include:
A history of dieting (particularly when going on extensive fasts and other radical type diets) during a person’s adolescent yearsAn obsession with being thin or losing weight, and the pressure to diet, which can result in anxiety, stress and shame, triggering the desire to binge
Complications
Many complications may arise from BED. Examples include:
Obesity or being overweight High cholesterol levels Hypertension (high blood pressure) Diabetes Gallstones Certain types of cancer Heart disease Mental illness (particularly depression, anxiety, and substance abuse)
In addition to specific disorders, complications of BED may include many different imbalances of various body systems (such as the hormonal system). People with eating disorders (including BED) may have disturbances in various functions of the body, including:
Problems with normal digestionAppetite problemsInsomnia (trouble sleeping)Disturbances in normal physical growth and developmentHormonal problemsAlteration in kidney functionEmotional problemsMemory and thinking problems
