Have read an interesting article from Dr Mark Porter in the Times. Pregabalin , a nerve painkiller, has found to be helpful in IBS.
He also mentions a different condition they're finding which might help some of you on here. It's called BAD, biliary acid diorrhea ,excess bile acid in the lower bowel which speeds it up too much. Symptoms are diorrhea, bloating and unusually coloured stools either green or yellow!. Symptoms are usually worse after fatty meals and there is no infection.
Treatment and testing is done at a gastroenterology clinic where a trial with a cholestyramine drink is undertaken. It can mop up the bile acid and stop symptoms. Ideally 1 or 2 sachets a day can achieve this.Self - help measures are eating a low fat diet and having breakfast and lunch as main meals and just a snack at teatime as diorrhea can get sufferers up in the night!. A genetic glitch can be the cause.
Hope this might help some of you.
