Hi, Welcome to health care magic, Your indigestion problem could be due to acute gastritis or irritable bowel syndrome (IBS) but it has almost no relation with mitral valve regurgitation. You may go for routine blood check up with urine and stool examination for R/M and ova or ultrasound of abdomen if symptoms persists longer. Here, I will give below instructions for some relief. 1) You should take frequent small feeds rather then two large meals. 2) Avoid carbonated drinks,caffeine products. 3) The food that you are eating should be chewed well . 4) Take high fiber diet,fresh fruits which will move easily in the gut. 5) Avoid excess oil,ghee and fatty or junk foods. You can be given oflox-oz which is a very good drug specially in the treatment of gastro-intestinal infection but you should also take proton pump inhibitors like pantoprazole or rabeprazole which will reduce the excess acid production in stomach. In spite of all these measures, if your problem persists then you should consult physician who may know all the relevant tests that I have mentioned to rule out any disease in the abdomen and can prescribe you appropriate medicines. You may continue with protonix as you are taking and there is no issue with that. Hope this detailed answer will help you. Wish you good health, Regards,
