Hello I had gone through your question diligently and I will try to help you out in best possible way it can be caused by Acid reflux which can be manged with certain dietary and life style modifications like Avoid fatty fried spicy and junk food or carbonated drinks Have lots of fresh fruits and vegetables You can take curd, cold milk or fruit juices You can liquid paraffin or lactulose for bowel movement Avoid smoking and alcohol relaxation exercises to allay anxiety and stress. Don t lie down immediately after earing something If you can provide me more details like your age and presence of any other metabolic illness like diabetes or thyroid and liver disease , I will be able to help you better In my opinion you should consult a gastroenterologist for baseline investigations like liver function tests, an endoscopy if need be and X ray chest to rule out hiatus hernia Hope this answers your question Thanks and regards
