[/INST] Hello, Mostly it's an acidity and reflux disease. Do you have upper abdominal pain, nausea, bloating, burping, increase in pain on food, sour water feeling in throat or chest burning, if yes it further supports the diagnosis? You should avoid fatty, oily and high calorie diet. Have some walk after having food instead of taking rest. Have multiple small meals instead of heavy meals. Have regular sleep habits and avoid stress. Lots of green leafy vegetables, fruits. Avoid smoking and alcohol if any. You can get prescribed tab Pan DSR 40 mg before breakfast once a day for 2 weeks. </s>
