A Lancet study suggests that popular weight-loss drugs could lead to muscle loss. Researchers recommend combining these medications with proper nutrition and exercise.

Only 13 states currently allow Medicaid to cover treatment of obesity using glucagon-like peptide-1 agonist (GLP-1) medications, researchers said.

The FDA is warning that patients taking GLP-1s may be at a higher risk of inhaling fluid into their lungs while under anesthesia.

In general, when a person prepares for a surgery, the guidance is to fast before going under anesthesia– but for patients, on gGLP-1's there may still be gastric juices, in the stomach, since the drugs slow down the process of emptying the stomach.
