Causes of anorexia
There is no one reason for eating disorders.Despite the concerns about weight and body shape, which play an important role in all eating disorders, the real cause of these disorders involves many factors: genetic and neurobiological, cultural and social, behavioral and psychological.
Genetic factors. Anorexia is eight times more common in people who have relatives with the disease.Studies of twins indicate that they have a tendency to share specific eating disorders (anorexia, bulimia, obesity).Researchers have identified specific chromosome that may be associated with bulimia and anorexia.
Biological factors. Hypothalamic-pituitary-adrenal system of the body can play a role in eating disorders.This complex system has its origins in these regions of the brain:
- hypothalamus.The hypothalamus is a small structure that plays an important role in the control of behavior, such as eating, sexual behavior, sleep, and regulates body temperature, hunger and thirst, is involved in hormone secretion.
- Pituitary.The pituitary gland is involved in the management of thyroid and adrenal glands, growth and sexual maturation.
- Tonsils.This small almond-shaped structure associated with emotional regulation and control activities, including anxiety, depression, aggression, and affection.
Hypothalamic-pituitary-adrenal system is involved in the development of certain neurotransmitters (chemical messengers in the brain) that regulate stress, mood and appetite.Disturbances in the development of three of them - serotonin, norepinephrine and dopamine, can play a particularly important role in eating disorders.Serotonin is involved in the well-being, anxiety, and appetite (among other features), decreased levels of serotonin in the brain is one of the factors in the formation of depressions and severe migraines.Norepinephrine is a stress hormone.Dopamine is an important part of the "system of promotion" of the brain, because it causes a feeling of pleasure (or satisfaction), what affects the processes of motivation and learning.An imbalance of serotonin and dopamine may partially explain why people with anorexia do not feel a sense of pleasure from food and other typical amenities.
- Severe trauma or emotional stress (eg, death of a loved one, or sexual abuse) during puberty.
- cultural environment.
- Tendency towards perfection, fear of ridicule or humiliation, the desire to always be "good".The belief that being perfect in appearance, is a prerequisite in order to be loved.

- Obsessive-compulsive disorder - anxiety disorder, followed by obsessions, recurrent or persistent mental images, thoughts that can lead to compulsive behavior, which manifests itself in the form of repetitive, rigid and self-prescribed procedures designed to prevent the manifestation of obsession.Women may become obsessed with exercise, diet and food.
- Phobias.Phobias often precede the onset of an eating disorder.Social phobia, when a person is afraid of being humiliated in public, are often found in both types of eating disorders.
- Panic disorder.It is characterized by periodic attacks of anxiety or fear (panic attacks).
- Post-traumatic stress disorder - anxiety disorder, which occurs in response to life-threatening circumstances.
- Depression.Depression is often to blame for anorexia and bulimia.
- Narcissistic personality disorder: the inability to calm themselves, inability to empathize with others, need for admiration, increased sensitivity to criticism or defeat.
- Overweight.Extreme disorders of eating behavior, including the use of diet pills, laxatives, diuretics, and vomiting occur more often in overweight patients than in normal adolescents with normal weight.
