**Question:** All of the following may be seen in Anorexia Nervosa, except

A. Pulmonary embolism
B. Hypothyroidism
C. Chronic kidney disease
D. Hepatitis

**Core Concept:**
Anorexia Nervosa is a psychiatric disorder characterized by an intense fear of gaining weight, leading to severe weight loss and disturbances in body image. It is classified as a severe eating disorder and is associated with high morbidity and mortality due to medical complications.

**Why the Correct Answer is Right:**
Hepatitis (D) is an inflammation of the liver, caused by viral infections, autoimmune reactions, or drug-induced. The clinical presentation includes jaundice, fatigue, and abdominal pain. Anorexia Nervosa patients are generally young females with normal or low body mass index (BMI), making it unlikely to observe hepatitis in this population.

**Why Each Wrong Option is Incorrect:**

A. Pulmonary embolism (Option A) is a blockage in one of the pulmonary arteries in the lungs, leading to hypoxia and respiratory distress. Anorexia Nervosa patients usually have low BMI, which reduces the risk of this life-threatening complication.

B. Hypothyroidism (Option B) is a condition characterized by a deficiency of thyroid hormones, leading to fatigue, weight gain, and cold intolerance. On the contrary, Anorexia Nervosa patients tend to have low BMI and weight loss, making hypothyroidism less likely to be a presenting feature.

C. Chronic kidney disease (Option C) is a progressive impairment of kidney function, often due to hypertension, diabetes, or autoimmune diseases. Anorexia Nervosa patients generally present with weight loss, making chronic kidney disease an unlikely diagnosis.

**Clinical Pearl:**
Understanding the core features of Anorexia Nervosa and their differential diagnosis is essential for early identification and appropriate management of the condition. Recognizing the distinct clinical presentation of each condition can prevent misdiagnosis and improve patient outcomes.
