Do some women lose weight taking oral contraceptives?
If they do, it’s more likely to be a result of another lifestyle change, rather than simply taking the pill.
There were stories in the media about the combined oral contraceptive pill Yasmin when it first became available in 2001, because some women noticed weight loss after starting to take it. The reality was that the weight loss they experienced was most likely water weight, which may have been reduced after switching pills. The progesterone in Yasmin is a different type of synthetic hormone that’s thought to work with your body chemistry and affect any excess sodium and water.
Yasmin may have a minor diuretic effect and help to reduce hormonal bloating but it won’t be fat that’s lost, just water.
