Eating disorders are serious, complex mental health conditions characterized by persistent, harmful disturbances in eating behaviors and related thoughts and emotions. They are not merely about food or weight but often represent coping mechanisms for emotional distress, serving to provide a sense of control or manage feelings. These conditions can affect anyone, regardless of age, gender, or body size, and can be fatal if left untreated.
Types of Eating Disorders
Anorexia Nervosa
Characterized by severe food restriction, intense fear of gaining weight, and a distorted body image. Individuals often see themselves as overweight even when severely underweight.
Bulimia Nervosa
Involves cycles of binge eating followed by purging behaviors (self-induced vomiting, laxative misuse, fasting, or excessive exercise) to compensate.
Binge Eating Disorder (BED)
Marked by recurrent episodes of eating large quantities of food and feeling out of control, without regular compensatory purging behaviors.
Avoidant/Restrictive Food Intake Disorder (ARFID)
Limiting food intake based on sensory characteristics or fear of negative consequences (choking, vomiting), rather than body image concerns.
OSFED
Other Specified Feeding or Eating Disorders include conditions that cause significant distress but do not meet full criteria for others, such as atypical anorexia.

- Assertion of Control: Managing life when it feels chaotic.
- Self-Punishment: Expressing pain indirectly (Restrictive Intake Self-Harm).
- Interpersonal Influence: Communicating distress or managing social distance.

- Gastrointestinal: Severe constipation, acid reflux, and chronic dehydration.
- Bone Health: Significant bone loss (osteopenia/osteoporosis) increasing fracture risk.
