Causes of Compulsive Overeating
The causes of compulsive overeating are divided into psychological, social, and biological.
The main psychological root cause of psychogenic overeating is the inability to cope with emotions caused both by external unfavorable factors and by inner conflicts. Various emotions can trigger a binge: resentment, being unable to change a situation, guilt, fear, or anxiety.
Many patients suffer from low self-esteem and feel unable to meet the expectations and demands of those around them. From childhood they became used to coping with negative emotions through food because they did not find support from adults. Many patients have had a habit since childhood of eating a lot of sweet or fatty food, or eating without hunger "to keep company." They often suffered because of difficult relationships with adults and conflicts in the family.
Social causes of nervous overeating include the cult of slimness. When a person has excess weight, their sense of self-worth drops, and feelings of guilt and inferiority appear. Food helps to drown out these negative feelings. As a result, a vicious circle forms in which the factors feed and reinforce each other. The inability to stop eating causes increased anxiety, which further worsens the existing eating disorder. The likelihood of binge episodes is also higher in children whose parents encouraged them or calmed them with food.
Biological causes of compulsive overeating include a hereditary predisposition. Researchers have linked three genes to weight gain with systematic overeating. These are the Taq1A1, GAD2, and FTO genes. A tendency toward nervous overeating also increases with an inherited predisposition to heightened anxiety and depression.
