Hello, Its most probably an acidity and gastritis. You should also get tested for h pylori infection by urease breath test if not already done on endoscopic samples. You should avoid fatty, oily and spicy 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 or esomiprazole domperidone combination beforebreakfast once a day for few weeks. If not adequately relieved, then you should add Syr sucral O or gelusil two teaspoon three times a day for a week. Hope this helps you and get back if you have any doubts.
