Can Metamucil initially CAUSE diarrhea?

Hi all,

I was doing pretty well in recent weeks (small amounts of mucus, no blood, some tenesmus at night). I take Canasa every night, and it tends to give me mushy stool. I was hoping to try Metamucil to bulk it up a bit. I took one capsule of Metamucil on day 1 with breakfast (around 9am), and had a bout of diarrhea that night. I tried again on day 2 (same time, around 9), and had bouts of D throughout the day, which has continued until now. D has never really been a problem area for me with my UC, so I am attributing it to the Metamucil.

I know others have said that symptoms of gas and bloating will clear up with continued use (and gradually increasing dosage) but what about diarrhea? Is this temporary, or is it a sign that this med is just not for me?

I'd appreciate any advice!

If soluble fiber, it should not cause the D, but you might notice more D. It still has residue. The residue has to exit. IF the amount of water the dose can help bulk up is small compared to the amount of water and spastic activity in your colon, you will get runny fiber coming out.

Maybe try again when stools have already started to bulk, and then help bulking with fiber.

good luck

You might what to try skipping Canasa for a few days. I had most of the symptoms you've reported from this suppository.
