Hi, Welcome to health care magic, Stomach or intestinal pain after eating could have many causes which are excess stomach acid secretion or acute gastritis or Helicobacter pylori infection or food allergy. You may undergo routine blood investigations and H.pylori,liver function tests,urinalysis and abdominal ultrasound if not done earlier to detect the underlying cause. Treatment is mainly depend on the cause but you may take symptomatic treatment meanwhile. Antacids like h2 blockers (ranitidine) or proton pump inhibitors (pantoprazole) will help to reduce excess acid production in stomach. You can also take digene gel or liquid or ulcero-protective agents like sucralfate to reduce the burning sensation. You should also take some dietary measure. Eat plain foods like boiled rice and green leafy vegetables without adding spices or oil. It will help to neutralize digestive acids and also they are easily digestible means there will be no need of extra stomach acid. Avoid oily,spicy and fast foods Avoid eating full stomach at a time rather have small meals frequently. Consult physician or gastroenterologist for detailed medical history and clinical examination to diagnose the cause. Thanks and Regards,
