I've been taking fiberSure for 3 days now. The first day I went ok. But it seems to have constipated me. I incresased it to 2 tsp. today and still nothing? Is this normal at first? I have IBS- w/ C and also lactose intolerant.
I have had the same experience with fiber supplements. For some of us with IBS C, it is simply impossible to take fiber this way.
My GI doc explained it this way. When you are backed up due to C, the colon is not able to empty itself through normal peristaltic contractions because it is so full. In addition, constipation is almost always related to lack of hydration in the colon. Adding more fiber (which always extracts fluid from the gut and bulks the stool even more) can create an even more complex problem.
When I feel that things are not moving properly and that high fiber foods are having a binding effect on me, I increase the amount of good fat in my diet and load up on water. In extreme situations, I will take a laxative, clean out, and start all over.
