## Core Concept
Anorexia nervosa is a serious eating disorder characterized by a distorted body image and an intense fear of gaining weight, which leads to restricted food intake and significant weight loss. The management of anorexia nervosa involves a multidisciplinary approach focusing on nutritional rehabilitation, psychological therapy, and medical monitoring.

## Why the Correct Answer is Right
The correct approach to managing anorexia nervosa often involves a combination of **family-based therapy (FBT)**, **cognitive-behavioral therapy (CBT)**, and **nutritional counseling**. Among these, FBT has emerged as a particularly effective approach, especially in adolescents, where parents are empowered to take charge of their child's eating habits and help them gain weight. Nutritional counseling aims to establish a healthy eating pattern and achieve a healthy weight.

## Why Each Wrong Option is Incorrect
- **Option A:** While certain medications like selective serotonin reuptake inhibitors (SSRIs) may be used to treat co-occurring conditions such as depression or anxiety, they are not the primary treatment for anorexia nervosa itself.
- **Option B:** This option might suggest a treatment that is not commonly recognized or established as a first-line treatment for anorexia nervosa.
- **Option C:** Although hospitalization may be necessary in severe cases of anorexia nervosa, especially when there is a high risk of medical complications or when outpatient treatment has failed, it is not considered a first-line treatment but rather a part of management in specific situations.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the management of anorexia nervosa requires a **multidisciplinary team approach** including a doctor, a therapist, and a dietitian. Early intervention and **family involvement**, particularly in younger patients, significantly improve outcomes.

## Correct Answer Line
**Correct Answer: D.**
