An eating disorder characterized by a distorted body image and an intense fear of gaining weight. Individuals with AN restrict their food intake severely.

An eating disorder characterized by episodes of binge eating followed by compensatory behaviors, such as purging (vomiting).

A category for those with eating disorder symptoms who don't fit the criteria for anorexia or bulimia.

Characterized by repeated episodes of eating large quantities of food in a short period of time, without compensatory behaviors.

A suspected disorder where people eat significantly during the night, often linked to circadian rhythm abnormalities.

An eating disorder where individuals eat non-nutritive substances like paint, dirt, or hair.

Repeated regurgitation and rechewing of food, often seen in children with developmental issues.

Eating disorder where people avoid or restrict certain types of food, not because of fear of weight gain.

A rare genetic condition causing compulsive overeating and often leading to obesity-related health issues.

A syndrome related to brain injury (especially stroke or damage to frontal lobes) that leads to excessive appetite.

Characterized by excessive eating.

An eating disorder marked by a severe restriction of food intake, intense fear of gaining weight and a distorted perception of body image.

A type of anorexia nervosa where weight loss is achieved through dieting, fasting and exercise.

A type of anorexia nervosa where weight loss is achieved through purging behaviors like vomiting, laxative abuse, and diuretics.

Anorexia nervosa can be classified into restricting and binge-eating/purging types by the method used to limit calorie intake.

Anorexia nervosa is more prevalent in women with 0.5-2% lifetime prevalence rate, predominantly found in middle-to-upper classes.

Anorexia nervosa typically begins in adolescence with incremental restriction of food groups then progresses in restricting diet.

Severe restriction can lead to multiple, potentially life-threatening medical consequences (low blood pressure, heart rate irregularities, osteoporosis and loss of libido etc..).

Factors that increase the likelihood of developing anorexia nervosa (AN), but do not guarantee it.

Abnormal serotonin metabolism is linked to characteristics like perfectionism, inflexibility, restraint, abnormal satiety, and anxiety in AN.

A personality trait characterized by a strong need for order and flawlessness, often involving rigid control over one's life and appearance, in AN.

An abnormal ability to feel full. People with AN may not experience satiety signals as normal.

Hypothalamic-Pituitary-Adrenal axis; a complex system in the brain that regulates the body's response to stress.

Parents of children with AN often report more obstetric complications and higher levels of anxiety than average.

parents of children with AN are more likely to exhibit dismissive or insecure attachment styles, which affect emotional expression and bonding, potentially also impacting stress response.

Premature birth or other significant trauma at birth has been shown to be more common in children who develop AN.

Factors like abnormal attachment, maternal stress, birth trauma and serotonin issues have similar negative effects on the body and brain's stress response mechanisms.

Part of the brain that initiates the stress response via Vasopressin (AVP) and Corticotrophin Releasing Hormone (CRH).

A hormone that is released by the adrenal gland in response to stress which helps with stress response, but high levels lead to various health problems.

Problems with the HPA axis (stress response system) are seen in individuals with AN, often causing abnormal stress responses and risk during puberty.

Changes in the HPA axis during puberty are considered a risk factor, as they create vulnerability to the development of AN, potentially combined with fears about menarche.

A major stressful life event often directly precedes the onset of AN.

Animal model demonstrating stress-related anorexia resulting from HPA dysfunction, in AN.

A reduced sensitivity to signals that indicate when the body needs food. It is a trait/risk factor in AN.
