Question

My doctor offered semaglutide. I am worried about what happens when I stop, and about losing muscle.

These medications have been used for type 2 diabetes for years and have a well-documented safety profile, with nausea and constipation as the common complaints. Two things matter for the questions you are asking: protein intake and resistance training, which protect muscle while you lose weight, and a plan for what comes after. Many patients regain weight if the medication simply stops with nothing in place, so we taper alongside nutrition and habit work, and we monitor labs throughout.

For women I would add that weight gain around perimenopause often has a hormonal component worth evaluating, so the medication should be part of a broader plan rather than the whole plan.
