Do birth control pills cause excessive weight gain?
No, birth control pills do not generally cause excessive weight gain. A review of 44 studies found no evidence that birth control pills caused weight gain in most women
[1]. However, some people may experience water retention and a slight increase in appetite, which can lead to temporary weight gain. If you do experience weight gain after starting birth control, try being patient, increasing exercise, changing birth control pills, or speaking with a doctor to find a lower-dose pill
[2]. Common side effects of birth control include nausea, but it is unlikely to cause excessive weight gain.
