At the age of 13, Lexi underwent bariatric surgery, where 80 per cent of her stomach was removed. She initially lost 29kg. However, nine months post-surgery, she regained some weight, and her significant hunger returned.
Recently, Lexi was prescribed Wegovy, a weight-loss medication approved by the US Food and Drug Administration (FDA) to treat obesity in individuals aged 12 and older.

Wegovy belongs to the new class of injectable medications, originally used for the treatment of Type 2 diabetes but now FDA-approved for long-term weight management.
In January 2023, the American Academy of Pediatrics (AAP), which is the largest professional association of pediatricians in the US, revised its guidelines for treating children with obesity for the first time in 15 years, now endorsing early medical interventions like surgery and weight-loss medications, alongside lifestyle and behavior modifications.

Dr Fatima Cody Stanford, an obesity medicine physician and an associate professor at Harvard Medical School, says there’s been “a noticeable shift in recent years in how obesity and obesity medications are discussed within the paediatric and broader medical fields”.
However, she says irreversible treatment such as bariatric surgery and indefinite use of medication at age 12 “must be approached with caution”. It’s important to balance the potential benefits of anti-obesity drugs against the unknown long-term effects, she says.
“However, the psychological and emotional aspects, such as body image, potential dependence on medication, and identity formation, should be openly discussed.”
High cost of weight-loss drugs
“Surgery is final … there’s no reversing it,” she says, adding that she believes bariatric surgery remains an essential option if other treatments fall short.

Bariatric surgery usually leads to substantial weight loss, but Lexi’s MC4R deficiency made her procedure far less effective.
Despite more weight-loss drugs hitting the market, many people in the US still can’t afford them.
Medicare, the federal health insurance, is prohibited from covering weight-loss drugs by law. Most private health plans don’t cover them either, primarily, due to their high cost. Bariatric surgery, on the other hand, is covered by insurance companies.
