Fermented foods is good for you and for gut bacteria, but food fermenting in your stomach is not the same thing. it can cause other discomfort (besides burping) and infection, etc, but I'm sure if that were a risk it would be mentioned.

A Google search told me that Mounjaro causes burping because the food sits in the stomach longer and has time to ferment. Isn't fermented food healthy? Is this a good thing? I'm on 7.5 mg Mounjaro if it matters.
