I have had a stomach disease since childhood. Frequently I am having dysentery and this problem causes me a lot of pain when I eat some food like meat, bean, milk, eggs, etc. I have functional dyspepsia of digestion. What food will be best for my digestion? And I need your kindly advice as to whether I should go for a medical test like endoscopy or medicine which doesn’t have any side effect. I look forward to your kindly response.
