Hello and welcome to HCM,
The pain that you have described is unlikely to be due to some heart problem.
It appears to be due to some abnormality in the gastrointestinal tract.
Pain aggravated by taking food suggests a gastric (or
stomach ulcer).
The first thing to do is to consult a gastro-enterologist and get an upper gastrointestinal
endoscopy done.
This investigation will pick up presence of any ulceration, abnormality, or growth in any part of upper gastro-intestinal tract whether
esophagus, stomach, or first part of
duodenum.
This investigation is accompanied by
biopsy studies.
In this investigation a part of lining of stomach and duodenum are taken and studied microscopically to look for changes in the mucosa (or lining).
Further management will be guided by the results of these investigations.
Ulcers are treated by anti-ulcer drugs, growths are treated by removal, and so on depending on the main problem.
Thanks and take care
Dr Shailja P Wahal
