It is a little known about treatment ideal because it doesn't get absorbed and can also be used when IBS-D is a problem too.

It is available as tablets, powder or granules which can be spread on your food.

Cautions WithThis Fiber

Think carefully about using it if you have decreased bowel motility or a narrowed intestine such as those seen with Crohns disease. 

These are very unusual conditions, so in most cases it isn't an important factor.

Methylcellulose Fiber - My View

It is an interesting option, particularly in diarrhea as the drug swells on contact with fluid.

It can also be considered for constipation too as it works to bulk up stool by soaking up fluid in the bowel.

It is a fairly innocuous drug, but one that can be helpful for some sufferers.

It also has an effect to reduce appetite so can be doubly beneficial in those sufferers trying to loose weight.

The tablets are large, but can be crushed.
