GLP-1 Weight-Loss Drugs Bring Big Benefits, New Risks as Trials Accelerate
GLP-1 weight-loss drugs show benefits beyond shedding pounds, including reduced inflammation, potential arthritis relief, and cardiovascular improvements, and may even curb alcohol cravings. However, they carry risks such as vitamin deficiencies, loss of eating enjoyment (hedonia), reduced appetite for food, and muscle/bone loss during weight loss, especially in frail patients. Off-label use in people who are not overweight poses safety concerns. A new triple-agonist drug, retatrutide, may deliver 25–30% weight loss—similar to bariatric surgery—but brings more side effects and is in Phase 3 trials, with potential approval in the coming years. Long-term success depends on continued use with diet/exercise; stopping reverses effects and weight tends to rebound.
