Diagnosis Path: Diagnosis involves a comprehensive assessment including medical history, physical examination, and psychological evaluation. Healthcare providers measure BMI to determine severity, with a BMI between 16.0 and 16.99 kg/m² indicating moderate severity. They also look at physical signs of malnutrition, laboratory tests to assess electrolyte imbalances or organ function, and discuss eating habits and psychological state. Early detection is key to preventing serious health complications associated with the disorder.
