Is GLP-1 the same category of drug as insulin?

Different categories, even though both relate to blood sugar. Insulin directly replaces or supplements the hormone your body uses to move sugar out of the bloodstream, while GLP-1 medications work by mimicking a different gut hormone that stimulates the body's own appropriate insulin release, slows digestion, and reduces appetite. They can be used together in diabetes management, but they're not interchangeable and work through genuinely different mechanisms.
