Hormonal

Newer obesity management medications (OMMs), specifically semaglutide (2.4 mg) and tirzepatide (10-15 mg), demonstrate high efficacy comparable to metabolic bariatric surgery (MBS) in the short term (26-52 weeks), with tirzepatide achieving >15% TBWL.

For those seeking non-surgical weight loss, newer medications like semaglutide (2.4 mg) and tirzepatide (10-15 mg) are the most effective options available, with tirzepatide showing short-term weight loss (15.2%) comparable to surgical procedures. These require weekly administration and are generally more effective than older medications like orlistat. They are best used in conjunction with lifestyle interventions.
