Watch: Are weight-loss jabs worth the side effects?

A woman who purchased weight-loss jab Mounjaro online says she is now considering coming off the drug, as she believe it is causing her to lose hair. Rebecca Quarmby lost two stone (12.7kg) on a Slimming World programme, but decided to opt for the jab to lose further weight.

She told the BBC's Natalie Bell that she doesn't believe her GP would have prescribed the jab, had she approached them.
