I expected semaglutide to make my sugar go too low

When I first heard that semaglutide can lower blood sugar, I assumed hypoglycaemia would be one of the main problems with taking it.

Then I kept reading that when semaglutide is used on its own, low blood sugar is usually much less common than it is with insulin or some other diabetes medicines. I didn't really understand how both things could be true.

Has anyone had this explained in a simple way? I'm especially curious why it can help lower high glucose without continuing to push it lower and lower when glucose is already closer to normal.

I also keep seeing warnings that the situation can change when semaglutide is combined with certain other diabetes treatments.

My doctor explained it as being glucose-dependent. Semaglutide helps the body release more insulin when glucose is elevated, so it does not behave the same way as injecting insulin that can keep working regardless of the current glucose level.

The glucose-dependent part was what finally made it click for me. 'Lowers glucose' sounds like it should just keep lowering it forever unless someone explains that distinction.
