brand new j pouch and feeling alone

If you have just had the reversal then this could be a normal part of the recovery progress. I had a little bleeding after take-down but it only lasted a couple of days. If you start feeling worse and/or the bleeding continues, give your surgeon a call and let them know.

A little bleeding is not unusual. It should decrease over time as you get further out from surgery though, so if you have a sudden increase, do reach out to your surgeon.

It is normal to continue to see some mucus in your bowel movements from now on. The GI tract is always producing mucus and occasionally passes small amounts. It's normally "hidden" because it gets compacted in stool, but since the pouch doesn't really compact anything like a colon, you'll be able to see it most of the time. It isn't a sign of inflammation (unless you start passing HUGE amounts -- but even a small amount every day is normal).
