Eating disorders
Recognizing serious disturbances in eating and weight-control behavior—and finding appropriate medical and mental-health care.
What are eating disorders?
Eating disorders are serious, treatable illnesses involving persistent disturbances in eating, weight-control behaviors and related thoughts or emotions. They can affect people of every body size, age, sex, gender, race and background. Appearance alone cannot determine whether someone is medically stable.
They are not a choice or a lack of willpower. Biological vulnerability, psychological factors and social conditions can interact, and early assessment improves the chance of recovery.
Major eating disorders
| Condition | Core features |
|---|---|
| Anorexia nervosa | Restriction leading to significantly low weight, intense fear of weight gain or persistent behavior interfering with weight restoration, and disturbed self-perception. |
| Bulimia nervosa | Recurrent binge eating followed by compensatory behaviors such as vomiting, fasting, laxative misuse or excessive exercise. |
| Binge-eating disorder | Recurrent binge episodes with loss of control and distress, without regular compensatory behaviors. |
| ARFID | Avoidant/restrictive food intake causing nutritional, growth or functional problems without weight-shape concerns as the primary driver. |
| OSFED | Clinically significant symptoms that do not meet every criterion for another specified disorder; it can still be severe. |
| Pica and rumination disorder | Persistent eating of nonfood substances, or repeated regurgitation, respectively; both require medical evaluation. |
Possible warning signs
Eating behavior
Skipping meals, rigid food rules, secretive eating, binge episodes, purging or marked anxiety around food.
Body and exercise
Compulsive weighing, intense body checking, exercise despite illness or injury, or fear of rest.
Physical changes
Fainting, weakness, feeling cold, menstrual changes, dental erosion, swelling, gastrointestinal symptoms or rapid weight change.
Medical clues
Slow heart rate, low blood pressure, electrolyte abnormalities, kidney injury or abnormal liver tests.
When urgent help is needed
Assessment and treatment
Evaluation may include medical history, eating behaviors, mental health, vital signs, growth or weight trajectory, physical examination, laboratory tests and an electrocardiogram. Treatment is individualized and may combine medical monitoring, evidence-based psychotherapy, nutrition rehabilitation, family support and medication for selected conditions or coexisting illness.
Care may occur outpatient, in an intensive outpatient or partial-hospital program, residentially or in a hospital. The appropriate level depends on medical stability, psychiatric risk, available support and response to treatment.
How W8MD can help
W8MD can screen for disordered eating before and during weight-management care, review medication and medical risks, and coordinate referral to an eating-disorder specialist or higher level of care. Active or suspected eating disorders require a treatment plan centered on safety and recovery; appetite-suppressing medication or a restrictive weight-loss program may be inappropriate.
Frequently asked questions
Can someone have an eating disorder at a higher weight?
Yes. Serious eating disorders occur across the weight spectrum, and rapid loss can be medically dangerous at any starting size.
Is binge eating simply overeating?
No. A binge includes loss of control and is associated with marked distress; diagnosis requires a careful clinical assessment.
Can GLP-1 medication treat an eating disorder?
GLP-1 drugs are not a substitute for specialist eating-disorder assessment and treatment. Medication decisions require individualized risk review.
