Can you just stop a GLP-1 medication cold turkey, or does that cause problems?

Stopping isn't generally associated with dangerous withdrawal effects the way some medications are, but appetite and hunger typically return toward baseline once the drug clears your system, and for people on it alongside diabetes management, stopping can affect blood sugar control. It's generally recommended to discuss stopping with your provider rather than doing it unilaterally, particularly if you're using it alongside other medications that were dosed with the GLP-1 medication's effects factored in.
