Real-World Weight Loss: Surgery Outperforms Drugs, Study Finds
Imagine people trying to lose weight with medicine and surgery.
A study looked at both.
Those who had surgery lost a lot of weight.
Those who took medicine lost less weight in the real world than in earlier studies.
This means surgery might be better if you want to lose more weight.
If you stop taking the weight loss drugs, the weight loss may not last.
The study is a reminder that how we use these drugs and what we expect is important.
Study finds real-world weight loss from semaglutide and tirzepatide is less than in clinical trials.
Researchers compared weight loss in patients on weight loss drugs to those who underwent bariatric surgery.
Patients who had bariatric surgery lost an average of 26.5% of their weight after two years.
Patients using semaglutide and tirzepatide lost an average of 5.7% of their weight after two years.
Experts suggest factors such as discontinuation and titration affect weight loss.
