Meredith, Northern California - 09/28/2014

I am using warfarin, have no anal sphincter, and only about 1/2 of my colon left. This obviously causes BM problems. Metamucil was recommended by my gastroenterologist to bring either loose stools or constipation more to centered normal. I have been using it for several years twice a day including once when I brush my teeth before bed. It has changed my life because I now have a little control over this function. I also take an Imodium tablet every morning to slow the intestinal contractions down so that I have time to get to the bathroom. These medications gave me back some control over my activities, and there has been no negative side effect after the first couple of months of bloating. Stick to the recommended one teaspoon per dose (if sugar free) with plenty of water to avoid gas and bloating. Eat natural high fiber foods along with the Metamucil like oatmeal, whole wheat bread, beans (in moderation), leafy green vegetables, nuts, and other recommended foods. Avoid foods that you learn cause you problems. Cabbage and several dried fruits for me.
