Babies could be medicated in the womb to stop them from being born obese, doctors say.
They believe that giving overweight mothers-to-be a hormone pill could also improve the unborn child’s health well for decades to come.
The controversial idea comes amid growing concern about the toll the obesity crisis is having on pregnancies.
Around half of British women of childbearing age are overweight and more than 15 per cent of pregnant women are obese.
Their babies are more likely than average to be fat themselves as children and are at higher risk of diabetes and heart disease in adulthood.
As a result, many experts believe that improving conditions in the womb could have lifelong benefits to health.
