Both medicines influence appetite and help the body manage glucose. Each option has a slightly different effect on hunger and metabolism, and that difference often guides a clinician’s recommendation.
Semaglutide focuses on one hormone pathway. Tirzepatide acts on two, which may produce stronger appetite control for some people.
Studies often show greater weight reduction with tirzepatide at higher doses. Semaglutide still provides strong results and has been used longer, which gives doctors more experience with it.
Both medicines can cause nausea, reduced appetite, stomach discomfort, or fatigue. Tirzepatide may cause these more quickly because of its broader activity. Doctors usually start at the lowest dose and rise slowly.
Clinicians consider:
Either option can be useful, but one may suit your goals better than the other.
