There are multiple kinds of eating disorders that consist of varying symptoms.

 

Binge-eating

Binge-eating disorder includes a recurrent and uncontrollable urge to binge. Binging includes eating a large amount of food without the ability to control food intake at least once a week, which may be done discretely. The binging episodes could include eating rapidly, feeling uncomfortably full, eating without hunger cues, eating alone, feeling embarrassed about food intake, or feeling disgusted or guilty about yourself.

 

Bulimia Nervosa

Bulimia nervosa is a type of eating disorder that consists of binging and purging at least once a week. The symptoms of bulimia nervosa include recurrent episodes of binge eating with the incorporation of compensatory behaviors to inhibit weight gain. Compensatory behaviors include vomiting, laxatives, fasting, or over-exercising. It is common that individuals with bulimia nervosa are fixated on weight and shape determining self-worth.  

 

Anorexia Nervosa
Anorexia nervosa is an eating disorder that is characterized by restriction of food intake, fear of weight gain, reduction of food intake even at significantly low weight, altered perception of body, or self-worth becomes dependent on weight or shape. There are two subtypes of anorexia nervosa, which are the restricting subtype and the binge/purge subtype. The restricting subtype includes solely restriction of intake, fasting, or excessive exercise. Whereas the binge/purge subtype includes recurrent episodes of binge-eating or purging/compensatory behaviors. Avoidant/restrictive food intake disorder is a type of eating disorder that leads to lack of nutritional intake because of disinterest in eating or food, sensory related issues with food, or fear of consequences from eating. There may be significant weight loss, nutritional deficit, or supplemental feeding methods. Avoidant/restrictive food intake disorder is not driven by disturbance in body image, weight, or shape. 

There are other eating disorders that are less widely known, such as pica, rumination disorder, and other specified feeding or eating disorder (OSFED). 

 

Pica
Pica is characterized with eating nonfood substances for at least one month, without correlation to cultural practice or another mental disorder.

 

Rumination

Rumination disorder includes regurgitation of food; such as being spit out or re-swallowed/re-chewed without being related to a medical condition.

 

Other Specified Feeding or Eating Disorder (OSFED)

OSFED includes symptoms of an eating or feeding disorder that causes distress without meeting the full criteria for the aforementioned eating disorders.
