anorexia

This term operates on two distinct levels of medical severity. In a general clinical sense, it refers to a symptom of appetite loss often triggered by illness or medication, where the lack of desire to eat is a secondary effect of a primary physical ailment.

In a psychiatric context, specifically as anorexia nervosa, the word describes a complex mental health disorder. Here, the avoidance of food is a deliberate, driven behavior rooted in psychological distress and body image distortion rather than a biological failure of appetite.
