Hi,
Thanks for writing your query.
After reading your post, it seems that his symptoms are due to
Gastro Esophageal Reflux Disease (GERD).
An
Endoscopy may be helpful to confirm the diagnosis.
I would advise that he should take an antacid like
Omeprazole 40mg once a day before meals along with
Domperidone 30mg.
Following precautions will be helpful :-
1.Avoid spicy and oily foods.
2.Avoid being empty stomach for long periods.
3.Avoid mental and emotional stress.
4.Avoid smoking and alcohol, if any.
5.Avoid self medications, especially pain killers and
steroids.
6.Avoid gas producing foods like peas, cabbage, legumes, etc.
7.Avoid eating fast and talking while eating.
I hope this is helpful to you.
Thanks.
