Hormonal

Triple incretin agonists (GLP-1R/GIPR/GCGR) produce superior body weight reduction (up to 24.2%) compared to dual or mono-agonists, approaching the efficacy of bariatric surgery.

Retatrutide, a once-weekly injection targeting three gut hormone receptors, has shown remarkable weight loss results (up to 24% in trials). While side effects like nausea are common, they are often manageable by starting with a lower dose. This therapy represents a significant advancement over older GLP-1 drugs, offering efficacy closer to bariatric surgery without the surgical risks.

GoodSupportsHIGH confidence
In the phase 2 study for efficacy for obesity, after 48 weeks of treatment, retatrutide treatment induced a weight reduction of 15% or more in 60%, 75%, and 83% of the participants who received either 4, 8, or 12 mg of retatrutide, respectively... The highest dose, 12 mg, of retatrutide resulted in a mean weight reduction of 24.2% in obese participants after 48 weeks [102].
