Eli Lilly's new obesity drug retatrutide shows remarkable results. In a major trial, patients lost up to 30% of their body weight. This once-weekly injection targets multiple hormone receptors. The drug also improved heart health markers. Experts believe retatrutide could be a game-changer for treating obesity and improving patient health.

The results — the most weight loss ever seen in a medication trial — put the drug’s effectiveness on par with bariatric surgery.

A next-gen Eli Lilly obesity drug led to bariatric-surgery levels of weight loss in a study, but also saw patients dropping out because of side effects.

Eli Lilly's retatrutide shows promise, helping obesity patients lose over 28% of their weight in a key trial.
