Everytime when I eat there is no proper digestion I feel bloated in the evening time and I fear to have bowel movement 2 to 3 times a day(not regularly but sometimes). I feel there is lot of gas in my large intestine passing through the intestine to and fro, when I sleep up side down then the complete gas will be passed away through anus. I am also losing my weight I don't understand what my problem even I consulted gastroenterologist, MD, physician and even diabetologist but every one said that I'm alright there is no problem every report is good there is nothing wrong but why I'm facing these problems, please suggest me what I have what should I do?
