Hi! Good evening. I am Dr shareef answering your query. If I were your doctor, at the first instance I would insist for a regular timing of your diet. Keeping your stomach empty for a long time predisposes its mucosa to harmful effects of the natural acid produced inside the stomch, and if continued result in inflammation and possible ulcer formation in the long run. This could result in gastritis or a peptic ulcer in you giving rise to such symptoms of pain in the abdomen specially when your stomach remained empty. I would advise you initially for a proton pump inhibitor and a liquid antacid for a symptomatic relief at least for six weeks. In case it does not help, or the pain increases, I would not mind to refer you to a gastro-enterologist for a possible endoscopic evaluation of your gastro intestinal tract. Further management would depend on the clinical assessment and related investigations. 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.
