Irritable Bowel Syndrome Message Boards

Something you might consider is that some soluble fiber supplements cause IBS individuals bloating and gas while others don't. This happens because some soluble fibers are more readily fermented by bacteria in the colon than others. You might try a soluble fiber supplement that contains calcium polycarbophil which is suppose to be a non-fermentable soluble fiber supplement. Equalactin and Fibercon as I recall contains this soluble fiber.

Vitamin C fizzy could definitely be a problem.

Something else you might try for a couple of weeks and see if there is an improvement is removing fruits and foods with excess fructose (i.e. contains more fructose than glucose) such as pears, apples, grapes, melons, honey, etc from your diet. Heather has a note on fructose as IBS trigger in this newsletter titled "How can I avoid fructose and sorbitol". There is a fairly good list of foods to avoid in this posting. This problem is known as fructose malabsorption and has been shown to occur in up to 50% of the IBS population. It can cause serious gas, bloating, D and C.

You might also try restricting your consumption of wheat products to about the equivalent of two thin slices of bread per day. Wheat contains fructans which are part of the fructose malabsorption problem too.

Tell us how it goes.
