I have gastric problems every time after i eat. My pain is at top abdomen & then followed by diarea.?

According to your symptom it may be peptic ulcer or IBD inflammatory bowel disease or IBS irritable bowel syndrome try this take Tab PANTOCID once daily for 5-7 days in morning before breakfast. If it helps then most probaly its due to peptic ulcer. Otherwise also avoid dried and spicy food stop smoking if you smoke increase veg and fruit content of your food. Drink milk. I think these ill help if not consult your doctor
