Have you ever dealt with IBS, or is your digestive system on the sensitive side in general? Or has your gut always behaved normally and only started acting up now that you're on GLP's? How much weight do you need to drop? What was your starting weight, what's your goal, how old are you, how tall? Are you dropping weight right now? How fast? How many days have these symptoms been going on — if it's only a few, it could be a passing thing from a bug or something you ate, but if it's been longer, that points more toward reta or what you're eating.
Developing gut issues at this stage is most likely a reta side effect, though it's worth not ruling out other explanations. The clearest alternative is that your diet has shifted since starting reta — more or less fiber, for instance. Still, the most probable scenario is that reta and/or your new way of eating have altered your gut microbiome, which is now producing extra gas, leading to bloating and either cramping pain or diarrhoea because your intestinal muscles are unhappy.
There's no way to predict which dietary tweaks would help. Beyond sticking to small meals with modest fat content, adding fiber could either improve things or backfire. Psyllium husk is relatively low-risk and may actually firm up diarrhoea, but your gut might ferment it as well and end up more bloated. You could experiment with cutting out high fodmap foods to see whether that makes a difference — whether or not you have ibs or fodmap sensitivity normally, right now something in your gut is fermenting and driving the bloating and other symptoms, so reducing fermentable foods may ease things. Another approach: lower your reta dose, or skip the next shot entirely for a while and watch whether things improve as that dose clears. If you feel better after 2, 3, or 4 days without your usual weekly dose, that's decent evidence reta was the culprit — so resume at a smaller dose and titrate up extra slowly afterward. You might also try a broad multispecies probiotic or foods that support healthy gut bacteria. Looking much further ahead, if gut symptoms keep you from tolerating effective reta doses, tirz could suit you better, since it tends to cause somewhat fewer gut issues than reta.
Having lived with ulcerative colitis and IBS-d, I've spent far too long dealing with this garbage. One tricky part is that guts can react either slowly or quickly to changes — if your gut bugs have been thrown off, it might take a day, a week, or 2 for them to settle once you remove whatever upset them. So lining up symptom timing with food intake and drug side effects gets complicated, sometimes fast and sometimes with a long lag, which can make it nearly impossible to figure out what's happening. That's why it's usually smartest to change just one variable at a time — otherwise you won't know which thing helped or hurt.
