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
