Thanks for writing your query.
After reading your post, it seems that you might be having gastritis
and bleeding gastric ulcers
I would advise that you should get yourself clinically examined and investigated.
Following investigations may be helpful :-
2. Complete Blood Count
( CBC ).
3. Stool examination.
You should take an antacid like Omeprazole
40mg once a day before meals along with Domperidone
Further medical management can be planned after knowing the reports of the investigations.
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.Drink lots of water daily.
I hope this is helpful to you.
