An anal fistula is an abnormal tunnel that forms between the inside of the anal canal and the skin near the anus. It often develops due to infections in the anal glands, which lead to abscesses that fail to heal completely. The condition causes persistent pain, swelling, pus discharge, and discomfort while sitting or passing stools.
While medical intervention especially fistula treatment is essential for complete healing, diet plays a vital role in managing symptoms, preventing infections, and improving recovery after surgery.
Among all dietary recommendations, fruits stand out as one of the most beneficial components for fistula patients. They not only improve digestion and immunity but also help maintain soft stool consistency, which prevents irritation and supports healing. Here are the best fruits recommendations for Fistula.
