Thank you for the query.
Your cousin way of life can be an example how to get peptic ulcers. And it is possible, he already has such. That is why he should have upper GI endoscopy
performed at first before any treatment. This is very important as it can rule out stomach cancer
and Helicobacter Pylori infection
can be checked.
To easy acid reflux
symptoms he should avoid soft drinks, coffee, fatty foods. He should not lie down after a meal and the last meal should be 2 hours before sleeping.
Hope this will help.
