Hello, Since you are allergic to gluten, be very careful with your diet. Wrong diet will cause abdominal pain and diarrhea. Take food like meat, fish, eggs, plain milk, buckwheat, sorghum, millet, potatoes, chick pea, almond, herbs and well cooked fruits and vegetables. You should avoid wheat, barley, malt, bread, pasta, cereals (unless labelled gluten free), bear and all alcoholic drinks. Take anti diarrheal and stay well hydrated to avoid sodium potassium depletion and weakness. You can take antispasmodics, one stat to reduce pain abdomen. Take antacids and PPIs to reduce acid reflux. You are suggested to get clinically examined by a GP, get liver function tests. blood analysis and urinalysis done to detect any pathology that is causing you discomfort. You will be treated accordingly. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
