Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
I will advise you to get an endoscopic examination to confirm the diagnosis and pathology in upper part of gastrointestinal tract and should be managed accordingly. There can be peptic ulcer disease
, dysmotility of intestinal tract or may be narrowing.
I hope I have answered your query and this will help you. If you have any further query I will be happy to answer that too. Remain in touch and get-well soon.
