Bowel movements are very closely related to food intake and thus it is very important for patients with fistula to follow a strict diet. As a general rule, patients with fistula should avoid a diet plan that is low in fibre. Also, inadequate intake of fluids and water can worsen the problem of fistula. Patients with fistula should follow a diet designed to soften the stools to reduce straining while defaecation. In some patients, the fistula may be associated with bleeding and soreness. It is recommended to follow a high protein diet with adequate fluid intake in such cases.
