Hi! Good evening. I am Dr Shareef answering your query. You have not mentioned what the diagnosis was due to which you were operated in the past. However, for the bad acid reflux, i would advise the following for you: 1) Elevate the head end of the bed with two blocks on each side, so that the regurgitation does not occur while lying down, and the contents of esophagus and stomach flow down with gravity. 2) Some modification in your diet like more of roughage, enough liquids, avoidance of oily, fried, and fast food 3) Regular routine exercises like morning walk depending on your medical fitness. 4) Prescription for a prokinetic agent and a proton pump inhibitor for symptomatic relief and to have a control on the acid production and facilitate movement of gastric contents downwards 5) In case you do not get any relief or the problem increases in intensity, you would require opinion from a gastro enterologist along with a possible endoscopic evaluation of your upper GI tract. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
