alt Hacker NewsHere are some hits from a search for “studies on GI problems associated with GLP1's.” I have not read them start to finish but it’s a starting point for you to do your own searches off of. I used Kagi, for reference.

Ah, okay, I was thinking you might have run across something more recent. The latest science seems to be going mostly in the opposite direction, saying that with additional data it looks like early concerns about things like pancreatitis (and worse, cancer) were overblown. If there are some newly identified adverse reactions I'm always interested to learn more about them.
