“How long does diarrhea last after gallbladder removal?”

Unfortunately, this question is tough to answer. In MOST patients, diarrhea usually resolves within a few weeks to months. However, because bile is still being produced and constantly leaked into the small intestine instead of sequestered in the gallbladder, some people can have diarrhea for life. It is possible to fix this with a bile acid sequestrant like cholestyramine. I would suggest you talk to your PCP if you are still having symptoms more than a couple months after the surgery.

This varies a lot, but some patients have no diarrhea, some have transient diarrhea, while a smaller percentage may have diarrhea chronically, even lasting a lifetime (due to bile salts that dump into the colon). It is treatable using bile salt binding medicines.
