Quick update since I really appreciate everyone checking in. My doctor called back and figures it's probably not the mounjaro at all, more likely just a stomach bug, since why would it only start happening now out of nowhere. He suggested taking imodium and stepping the dose down for a week, and he didn't seem concerned in the slightest. That said, I'm thinking about getting a second opinion elsewhere, since losing total control over my bowels like this is something I've never experienced before, not from ozempic, not from any bug. Really grateful for all the advice everyone's given.
