Weight-loss drugs taken by many adults might be a useful treatment for children as young as 12.

More than 20% of 12 to 19-year-olds are considered obese, according to the CDC.

The American Academy of Pediatrics says weight-loss drugs combined with a healthy diet and exercise can help with excess weight before it leads to health conditions like diabetes, heart disease and high blood pressure.

Some doctors are worried weight-loss drugs could affect a child’s growth from undereating.

In a statement, the company that makes Wegovy said studies have found their medicines do not affect growth, adding the decision to prescribe a medication is up to the doctor.
