Does the contraceptive injection cause weight gain?
In some women, the contraceptive injection causes weight gain. Clinical trials for Depo Provera showed, that the average weight gain over 1 - 2 years of using the injection was 5 - 8 lbs. Women who used the injection over 4 - 6 years gained 14 - 16.5 lbs on average. This side effect does not affect all women, and some women find that they lose weight while using it.
