Hello. Thanks for using this forum. Usually night pains in the upper part of abdomen is related to underlying peptic disease, usually gastritis
or gastric ulcer. This happens mostly after consumption of fatty food and alcohol during dinner. You should consult with your doctor who can do an upper endoscopy
investigation to rule out the above. Try avoiding heavy meals at night for now. If you feel you are overweight
, then its also advisable to get an ECG done.
If you have further queries , feel free to ask.
