Hi thanks for contacting HCM.... Excess bloating can occur by lactose intolerance ...so if it present then lactose containing food restricted.... Celiac disease also can lead bloating ..so it is good you have tested for it.... For your bloating following also can be the cause..... -stress -smoking -excess fatty foods as they delay gastric emptying -more drinking of carbonated drinks -more eating of gas forming foods like cabbage , turnip , beans , onion etc... So correct above factors if present... Fiber diet taken more like whole grain,wheat bran , spinach etc... If needed fiber supplement can be given... Avoid butter , bread and fast food in excess as they can alter digestive habit... More water taken... If still problem continue USG done... Take care. Dr.Parth
