I had my gall bladder taken out as part of my bariatric surgery about 15 years ago. More recently, I've tried tirzepatide and semaglutide to get rid of the weight I've gained since, but I have not tried liraglutide.

I just dug into the literature a bit, and it's clear that liraglutide used for your purpose is getting a lot of attention right now. Here is a hot-off-the presses review paper: https://journals.lww.com/ctg/fulltext/2025/03000/treatment_of_bile_acid_diarrhea_with_glucagon_like.1.aspx.

Liraglutide is now only available in the brand form as Victoza, although independently, I've read that it's possible we will see it in a generic form by 2027 in the US. In the meantime, it's worth checking into whether your insurance plan will cover it, since it's otherwise quite expensive. Note that like all these GLP-1RA drugs, some people get side effects, primarily nausea, which is something most people can control by managing dosage level.

On the plus side, Victoza comes as a multi-pen -- that is, unlike single-use pens for Mounjaro or Zepbound intended for weight loss, you can adjust the dosage. In fact, now that I'm down to a low maintenance level dose of Ozempic (also a multi-pen), I'm able to use this technique (you'll see it called click-counting or microdosing) to cut the cost of the drug in half without resorting to sources of the drug that are not FDA-regulated. This is probably not something you want to do until you have some experience with how your body reacts to the drug, because it means using dose levels that were not studied in clinical trials.
