disclaimer I do not have a bigger brain.
The gel formed by psyllium doesn’t “coat the intestines”. It absorbs water from the digestive tract, forms a gel mass, and mixes and binds with the intestinal contents and bulks up the stool. In theory, as it binds, it can pick up sand particles and add it to the stool. That’s why it’s sold a sand colic preventative. This is the same action any water soluble fiber (like oatmeal) has - it absorbs water in the intestine and adds bulk to the stool (helping with constipation).[/QUOTE]
Then why does my vet recommend it as a hind-gut ulcer helper? I just assumed I guess (bad me) that the gel was coating the intestines thereby allowing them to heal. Maybe it’s the fact that it pulls more water into the intestine that causes the inflammation to go down?
