Altered Appetite

Quick answer
Altered appetite (ICD-10: R63.0 Anorexia; R63.2 Polyphagia; ICD-11: MD32) is a transdiagnostic symptom associated with depression, thyroid dysfunction, and metabolic change. DSM-5 and ICD-11 list it as a core depressive criterion. Thyroid and metabolic assessment guides management. Significant weight loss requires urgent investigation.
