Hormonal

GLP-1/GIP co-agonists (e.g., tirzepatide) induce greater weight loss and have a more favorable gastrointestinal tolerability profile compared to GLP-1 monotherapy (e.g., semaglutide or liraglutide).

If you are considering GLP-1 therapy for obesity, discuss the potential benefits of dual agonists like tirzepatide with your provider. They may offer greater weight loss and potentially fewer gastrointestinal side effects compared to GLP-1 monotherapy, although individual responses vary.

GoodSupportsHIGH confidence
Tirzepatide-induced reductions of body weight were over three times greater than with dulaglutide, being attributed to complementary benefits of GIPR/GLP-1R modulation on inhibition of appetite and gastric emptying, as well as the ability of GIPR to curb GLP-1 induced emesis, leading to improved overall effectiveness and tolerability.
