Frequently asked questions

Does ursodeoxycholic acid dissolve gallstones?

It can slowly dissolve certain small cholesterol gallstones and is used in some liver conditions, but it works gradually and is not suitable for all stones.

How does orlistat help weight loss?

It blocks absorption of some dietary fat. It works best with a lower-fat diet — otherwise it causes oily, loose stools.
