@annettam I’ve had microscopic colitis for more than 35 years but have never heard of bleeding being associated with it (doesn’t mean it’s not). However, maybe you should try to find out what the source of your bleeding is? Don’t think it’s from MC. Food-wise, I can’t eat anything with fiber when I’m in a flare up. Plain carbs will help stop it the fastest. Fiber supplements will only make it worse.
