Hi, thank you for posting!
I read your query very carefully and I understand your concerns.
According to your symptoms I can say that you suffer from IBS(irritable bowel syndrome
You should follow these tests in order to relieve your symptoms:
1. Eliminate spicy and acidic foods from your diet.
2. Reduce the amount of carbohydrates in your diet.
3. Eat high fiber foods.
4. Do not drink alcoholic and carbonated drinks, coffee and milk.
5. Quit smoking(if you do smoke)
6. Take proton pump
inhibitor medicines such as Nexium
However you need the following tests for confirming the diagnosis:
1. Abdominal ultrasound
2. Abdominal Ct-scan.
4. Liver function test.
5. Complete blood count
6. Urine test.
7. Stool culture.
Contact your gastroenterologist in order to discuss about the diagnosis and treatment.
All the best.
