is caused by the reflux of acid from stomach to esophagus and upper aero-digestive tract(throat & voice box) due to relaxation of the sphincter at the upper & lower part of esophagus.
It can be associated with the sense of something stuck in the throat.
Management consists of:
1. Lifestyle modification- like weight reduction, sleeping on the left side, or with upper body raised.
2. Dietary modification- avoid consuming irritating substances such as acidic & rich foods
3. Medical management- Proton pump
inhibitors like Omeprazole
,etc. (which prevent acid formation in stomach)
4. Surgical treatment- includes Fundoplication, done when medical measures fail.
So..it will be better to consult a Gastroenterologist
& start the treatment.
There is no need to worry...your son will be fine.
And please don't get so much concerned with the chances of him having a cancer.
Wish him a good health & speedy recovery.
Thanks & Take care.
