The usual scheme of things is to try and rule out anything nasty (like gastric/oesophageal cancer.) This is a very rare cause of problems.
This is usually quite a simple process, involving a doctor listening to your symptoms, he or she may feel your abdomen, and even send you for some blood tests.
The amount of "digging" he'll do will depend on your other "risk factors" the main one being your age. He will also ask about "red flags" (eg weight loss, food sticking in the gullet etc)
If he has any doubt, he's likely to send you for an "endoscopy." (Camera down your tum).
Usually symptoms are managed with ppi's (something like omeprazole) or lifestyle changes.
PPI's shouldn't be a problem, (but obviously ask your AME.) Regular "high" doses have been linked to dehli beli.
