There are many types of eating disorders, including Anorexia Nervosa, Avoidant/Restrictive Food Intake Disorder, Binge Eating Disorder, Bulimia Nervosa, Orthorexia, OSFED, Pica, and Rumination Disorder.
- Anorexia: An eating disorder characterized by an intense fear of gaining weight, a distorted body image, and an obsessive desire to become thin. People with anorexia nervosa typically restrict their food intake, often to the point of starvation, and may engage in other harmful behaviors such as excessive exercise or purging through vomiting or the use of laxatives.
- ARFID: A type of eating disorder that involves an extreme avoidance or restriction of certain foods, leading to weight loss, nutritional deficiencies, and other physical and emotional problems. People with ARFID do not have a distorted body image or a fear of gaining weight. Instead, they may avoid certain foods because of their texture, color, smell, taste, or other sensory characteristics, or because of past negative experiences such as choking or vomiting.
- Binge Eating Disorder: An eating disorder characterized by recurrent episodes of eating large amounts of food in a short period of time and feeling a loss of control over the eating behavior. People with BED often experience intense feelings of guilt, shame, and distress after binge eating episodes, which can lead to additional cycles of binge eating.
- Bulimia: Eating large quantities of food (binging) followed by compensatory behaviors such as vomiting, taking laxatives or diuretics, fasting, or exercising excessively (called purging). People with bulimia nervosa often experience a sense of loss of control during a binge episode, consuming large amounts of food in a short period of time. They may then feel ashamed, guilty, or disgusted with themselves, and engage in purging or other behaviors to try to eliminate the calories consumed during the binge.
- Orthorexia: An unhealthy obsession with eating only "pure" or "clean" foods, which can lead to a restrictive and rigid diet that may result in nutritional deficiencies and other health problems. It is not currently recognized as a separate eating disorder in the DSM-5, but many healthcare professionals consider it to be a type of disordered eating.
- OSFED: OSFED stands for Other Specified Feeding or Eating Disorder. OSFED is a diagnosis that is used to describe a range of eating disorders that do not meet the full criteria for anorexia nervosa, bulimia nervosa, or binge eating disorder. Some examples of eating disorders that fall under the OSFED category include atypical anorexia nervosa (where an individual has a low body weight but does not meet the full criteria for anorexia nervosa), purging disorder (where an individual engages in purging behaviors but does not binge eat), and night eating syndrome (where an individual consumes the majority of their daily calories at night).
- Pica: An eating disorder characterized by the persistent and compulsive consumption of non-food substances with no nutritional value over a period of at least one month. These substances may include items such as dirt, paper, ice, hair, paint chips, or clay.
- Rumination Disorder: An eating disorder characterized by the repeated regurgitation and re-chewing of food that has already been swallowed, followed by either re-swallowing or spitting out the food.
