Hi, thank you for posting!
I have gone through your query and I understand your concerns.
All of your symptoms are caused by IBS(Irritable bowel syndrome
) and by low blood pressure.
To improve your health condition you should avoid spicy foods, fats, egg yolks, alcoholic drinks, coffee and milk. Smoking
is a factor that aggravates your condition, you must quit smoking(if you do smoke).
To confirm the diagnosis you need:
2. Abdominal ultrasound
3. Complete blood count
5. Urine test.
You should also measure your blood pressure everyday for 2 weeks.
Consult your cardiologist and your gastroenterologist for the diagnosis and treatment.
All the best.
