Proctitis often causes flatulence which may be due to consuming foods that easily produce gas, or it could be due to poor digestion caused by inflammation of the rectum. At this time, you can consider taking some oral medications for treatment, such as oral drugs that regulate intestinal flora including Bacillus cereus and composite lactic acid bacteria, etc. The specific choice of medication should follow medical advice. Additionally, patients with proctitis should also pay extra attention to their diet and avoid spicy and stimulating foods as well as overly coarse foods. Foods and drinks like strong tea, coffee, strong alcohol, chili peppers, and mustard should be avoided as much as possible. It is advisable to eat light, easily digestible foods in small, frequent meals.
