Hi,
Thanks for writing your query.
After reading your post, it seems that you might be having
gastritis.
Following investigations may be helpful :-
1.
Endoscopy.
2.
Ultrasound of abdomen.
3. Liver Function Test ( LFT ).
4. Serum
amylase and lipase.
5. Stool examination.
I would advise that you should continue with Lansprazole. Further medical management can be planned according to 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.
7.Eat light meals prepared under hygienic conditions.
8.Avoid gas producing foods like peas, cabbage, legumes, etc.
I hope this is helpful to you.
Thanks.
