Hi,
Weight gain is a very common side effect of hormonal methods of birth control. However, how much a woman will
gain tends to vary. Weight gain is due to an increase in appetite and easier fat deposition as a result of the
increase in hormones.
On average, women who use Depo-Provera tend to gain 5.4lbs during the first year of use and 8.1lbs after two
years. Women who use the birth control pill gain, on average, about 10lbs during the first year of use. For
some women, they gain more while others may not gain any weight at all. It is also possible to have imbalance
hormones. It would be best to discuss this with your doctor. Blood test may be done to determine your hormone
levels. Vitamin supplementation may help.
Take care and regards.
