For the last year and 5 months I have suffered with severe gas. It has got to the point where for the last year I have had to lie down on the floor and physically pump at my stomach in order to be able to get the gas and anything else out. I can't eat during the day apart from sweets and fortijuice and eat once at night before having movicol to push everything through in the morning. After I eat I get severe pain and lots of fluid moves straight through to my rectum. When I say severe wind, it constantly comes out. I have to pump at my stomach and pass gas over 100 times a day and whilst I am on the toilet waves of gas come out. Once I have finished pumping at my stomach in the morning I can go the whole day until I eat in the evening without lying on the floor. Has anyone ever had anything like this or have any advice to solve it? I have had a selenium test, bile malabsorption test, colonoscopy, endoscopy, hydrogen breath test and the doctors still don't know what it is. I do have rapid transit and when I used to eat in the day, if I needed to go to the toilet I would have diarrhoea but then it would get stuck and I'd be pumping at my stomach until four in the morning. I am on symprove, have tried VSL3, don't tolerate gluten well, have a lactase enzyme when I have dairy and am on a low fibre and low fodmap diet. Please someone help.
