Had J pouch 2 years now, noticed lots of blood today

I would suspect the Aleve could easily result in bleeding. If I was feeling well otherwise, I would cease taking NSAIDS and see how if it stops in a few days. If still bleeding, check it out further. Just one opinion though.

It's hard to know how much blood "a ton" is, so it's hard to guess whether you have an emergency. If you are actively bleeding substantial amounts (e.g. an ulcer into a little artery) then you have an emergency. Seepage can go on for a long time, as many of us have experienced with IBD.

Bleeding from the pouch would often be bright red unless it sat around for a bit. Bleeding from the esophagus or stomach is often black by the time it comes out the other end. So a first guess would be small bowel bleeding, but that's just a guess.

I think it would be unusual to get bleeding from three doses of Aleve, but unusual things happen every day. Other causes may be more likely, though.

In any case, I'd suggest getting a referral to a good GI - you'll need it whether you visit the ED or not.

One dose of Aleve - even 3 of them - doubtful that would be the sole cause of your bleeding. If you have had other inflammation issues in your pouch, then I could see the NSAIDs causing this. Or, if you take Aleve or other NSAIDs consistently - yes, it could cause bleeding.

If it continues for a day or two, I would be making an immediate appt. with my surgeon or GI doc.

Do you have any update?
