Eating Disorders and Bariatric Surgery
Many people seeking bariatric surgery have eating disorders. While studies do not show eating disorders to be an accurate predictor for weight loss surgery outcomes, studies do show that people who have eating disorders either lose less weight or regain more weight after bariatric surgery than those who do not have eating disorders.

Night-Eating Syndrome (NES)
Night-eating syndrome is a lack of morning appetite and overeating at night. Agitation and insomnia are characteristic, making it not only an eating disorder but a mood and sleep disorder as well.
People who have this disorder eat nothing at all in the morning and eat fewer than average calories per day. They become depressed as the day wears on and then eat high-fat carbohydrates through the night to self-medicate. Carbohydrates increase serotonin levels in the brain and cause sleep.
Binge Eating Disorder
Binge eating disorder is compulsive overeating of great amounts of food, usually in about two hours. It is mindless eating that can continue even after a person is full.
Binge eaters use food as a coping mechanism to address stress and other unwanted emotions. They are normally unsuccessful and usually feel worst after gorging themselves. Read: What to Do About Binge Eating

Anorexia nervosa is a coping mechanism to alleviate stress, anxiety, or depression. It is symptomatic of a desire to control surroundings and compensate for low self-esteem.
Dieting to the point of starvation is possible.
Bulimia nervosa is often an attempt to avoid unwanted emotions. The primary characteristics of bulimia nervosa are binging and purging.
Bulimics gorge themselves with food, then induce vomiting or take laxatives. As with anorectics, bulimics are obsessed with body image and exercise to an extreme. They also misuse diet pills.
Bulimia nervosa and anorexia nervosa can be caused by sexual, physical, or emotional abuse. These disorders have also been linked to clinical depression.
Closley Monitor Eating Disorders after Weight Loss Surgery
Although many people who undergo bariatric surgery lose weight, people with an eating disorder are at increased risk physically and psychologically, according to Mirror-Mirror.
