How long do people typically stay on a GLP-1 medication before considering stopping?

It varies a lot. Some people use it for a defined period tied to a specific weight goal, but given how commonly regain happens after stopping, many clinicians and patients now approach it more like an ongoing/long-term therapy rather than a fixed-length course, similar to other chronic condition medications. There's no standard universal timeline; it's usually revisited periodically with a provider based on how things are going.
