###Human: Why is there irritation in the stomach while eating and gas troubles? ###Assistant: Hi. You have to modify your diet and lifestyle. Try to avoid or reduce the amount of gas forming foods in your diet. Also, reduce excess spice and masalas. Add more of salads. Try short frequent feeds rather than heavy food or meals three times a day. Keep yourself well hydrated with two liters of water daily. Avoid carbonated drinks, excess coffee and alcohol if any. Have regular aerobic exercises. Follow these measures consistently for a month and see the response. Regarding medicines, Nexium (Esomeprazole) is a good choice. Can have for 2 to 3 days whenever you have excess symptoms. An endoscopy and ultrasound scan of the abdomen, if not done, is highly recommended.
