I read carefully and I would suggest to exams like:
I am asking you about these exams because there are two main causes related with your concerns
- Stomach problems (gastritis
, ulcer, esophagitis
If these entire exams will be normal, we can say that you don't have organic problem but functional problem of your stomach and bowels.
If I were your treating doctor firstly I would suggest changing your lifestyle:
-avoid spicy food, fatty, soft drinks, smoking
and alcohol, tea and chocolate.
- use anti acids
- avoid stress
Wish you the best
If you have other concerns, feel free and ask me.
