Re Metamucil
I spoke just this weekend to a WOCN who suggested I try Metamucil to help with the low-level diarrhea I'm experiencing post-op to my colostomy reversal.
HOWEVER -- I am now operating with a nearly whole colon - only missing a few inches from surgery. I don't know how Metamucil would affect an ileostomy, esp. in light of the proclivity toward blockages.
Another option, listed in Lexmark Drug Information Handbook is a bismuth product, such as Pepto. It works on diarrhea but is also indicated to help alleviate odor in certain ostomies as well as odor in an anal incontinence situation. If this is true, you might get double-duty from Pepto.
One other thing to check out (and I would NOT start/restart any of this stuff without checking with your dr's nurse or the doc himself) is that bismuth products act in part on the flora (bacteria) in your intestinal tract. It's important to have a healthy balance of bacteria, hence such products as Activia yogurt "probiotics." As I recall, bismuth is one of the products that work on the bacteria heliobacter pylori (H. pylori) that is a culprit in ulceration of the stomach and other nasty occurrences. If there's a clear case of bacteria overrun, then bismuth is a good choice. I myself have considered looking into this matter re good flora balance, but haven't done the research yet.
There is one other OTC medication, Imodium (I believe that's loperamide) that is indicated for diarrhea. My understanding is that it is specifically an antiperistaltic, meaning it slows down the muscle movement of the intestinal tract. Diarrhea is commonly an imbalance in water retention, sometimes caused by bacteria, sometimes by peristalsis that's out of whack. I don't think Imodium does anything to the bacteria levels - it just slows things down.
Hopefully this information is, if not helpful, then at least somewhat educational.
Best of luck - let me know how things work for you.
