Which of the following is NOT a treatment for Crohn's disease?

Radiation therapy is not a standard treatment for Crohn's disease. This condition, which is an inflammatory bowel disease, is primarily managed through medications, dietary adjustments, and sometimes surgery.

Medication is commonly used to reduce inflammation, control symptoms, and maintain remission. This includes anti-inflammatory drugs, immune system suppressors, and antibiotics.

Surgery may be necessary for patients who experience complications such as strictures, fistulas, or severe symptoms that do not respond to medical therapy. It can help to remove damaged portions of the intestine.

Vitamin supplements are often recommended, especially when nutritional deficiencies arise due to the disease's impact on nutrient absorption.

Thus, while vitamin supplements, medication, and surgery play vital roles in managing Crohn's disease, radiation is not part of the treatment paradigm for this condition.
