Excessive farting. Suggest a medicine.

I would require more information to come to a specific diagnosis. There are multiple causes for flatulence. I would advise you to have deworming if you haven't in 6 months and antacids. These following steps may help: - Don't skip meals, don't crash diet and have liquid diet and slowly increase to solid food based on how you can tolerate it - Reduce/ Avoid spicy,fried, fatty, junk and oily food - Avoid/ Limit drinking coffee, tea and carbonated drinks to once a day - Exercise regularly (minimum 30 mins) - Increase daily intake of water to 3 liters - Avoid/Stop smoking and drinking if you have the habit - Reduce stress through methods such as yoga/meditation. If the condition persists or worsens kindly visit a gastroenterologist.
