** Thanks for contacting with your health concern 1. Since you have consulted your primary care doctor who have diagnosed you to have GERD but because the symptoms are still persisting despite taking medications for the same, and consultation with Gastroenterologist and investigation is still pending thus taking into considerations your symptoms, I m of the following opinion: i. Get a second opinion since it can be symptoms of underlying illness or infection which require medical intervention. ii. going by your history and symptoms, the most probable diagnosis could be functional IBS [irritable bowel syndrome] which is a collection of symptoms ranging from bloating, diarrhea, abdominal pain, constipation and IBS also often accompanies the chronic form of acid reflux [GERD], also the two conditions share a common disease mechanism, till then i. maintain proper hydration [to prevent dehydration] and replace with electrolytes [avoid apple, grapes, pear juice which can make stomach upset]. ii. Avoid fiber-rich diet, since it can make bloating/diarrhea worse [instead take plain white rice, boiled potato, plain toast] - avoid eating dairy products, spicy food, and spicy condiments, stay away from artificial sweeteners. - take less of strong spices (ginger, garlic), oily-fried-fatty food and flatus producing foods (peas, beans, dals) - eat slowly, avoid haste-irregular eating and sweet/heavy food which are difficult to digest and cause indigestion - since it is a psychosomatic disease thus tranquility of mind is must, as such Medhya drugs or a mild tranquilizer are useful.
