Unexplained Weight Loss & Anorexia: When to Seek Help

Unexplained weight loss always warrants medical evaluation. Causes range from hyperthyroidism, diabetes, malabsorption, depression, to malignancy. Anorexia nervosa is one possibility among many.

Red Flags for Anorexia

• Intense fear of weight gain despite low weight.
• Body-image distortion (feeling “fat” when emaciated).
• Restrictive eating, ritualistic behaviors, excessive exercise.
• Denial of seriousness of low weight.
• Amenorrhea (in females), cold intolerance, lanugo, bradycardia.

Action Steps

1. Schedule a primary care visit for history, exam, and basic labs (CBC, CMP, TSH, electrolytes, etc.).
2. Be honest about eating habits, exercise, and body image.
3. If an eating disorder is suspected, request referral to a specialist (eating disorder program, psychiatrist, dietitian).

Early diagnosis and treatment of anorexia significantly improve recovery outcomes. Do not wait.
