Hello Pooja Tiwari
I have read your mail in detail. It seem that either you have GERD or inflammation of the upper GI track. Both the condition can cause these type of symptoms. We have to keep in mind liver
disease and gall bladder
As you are taking a good healthy restricted diet, these problem can not be due to bad diet habits.
To find out the cause consult your gastroenterologist. Your doctor can advise you endoscopy
and upper abdomen sonography
and accordingly treatment can be planned.
