I have had a black stool during a BM every once in a while during this 11 month flare. I wouldnt say it has happened more lately, but I would say I've noticed it more lately versus blood just appearing in the water in a thick red. Of course sometimes I go and there is no blood at all. My stool overall has been regaining some normal form. it is kinda like a toothpaste form at times and the diarrhea that i had before I started the Entyvio has gone way down to the point where I'll get it once every few days. Most normal days it is 3-5 BMs with more of them being a lot of air and cramping.

After a brief search on Google, I found black stools can be caused by the things I ate (although nothing in the last 24 hours sticks out), taking Iron (I do take an Iron pill a day although this has been going on continuously for months), and that this is blood further up the digestive system which people attribute to Crohn's (praying that has nothing to do with this!!).

Is it worth a call to my GI in the morning? I have an appointment with him later in the month and my next infusion of Entyvio next week.

I think I'd want to get checked out for darker blood. Hopefully it's something you ate, but what? I've eaten beets and thought I had dark red blood, but that's the only thing that's ever effected my stool in that way. Iron pills for me usually make things green, not black. It's likely it's nothing worrisome, as it sounds like you're healing, but better to be safe than sorry. When was your last scope?

I am happy you're feeling so much better on Entyvio.

Thanks for the response notsosicklygirl

I believe my mother and I figured out the problem. My puppy was diagnosed with a parasite, Giardia. Her vet specifically warned that people with autoimmune problems like us are more prone to have the parasite transmitted to them.

sure enough, i had cleaned up her accidents in our house before we knew it was a parasite and before we knew it was transmittable. i ran through the symptoms and it seems like that has to be it.

call to my GI will happen tomorrow and will likely do a stool sample. i'm just really bummed out because this will likely force me to push back my infusion of entyvio.

Giardia usually causes very watery, profuse diarrhea, but not blood.

Good idea nonetheless to get a stool sample tested. Have them test for blood in the stool too.
