Does Mirena cause weight gain? A small segment of women who has been using it, has reported gain as a result. This is not a general side effect as there have been cases where some people experienced weight loss after getting the device fitted.


Although it may not be a direct side effect, one particular woman reported she gained 20 pounds over a period of two years while on this IUD. In user reviews, we see that those who took weight could not shed off the fats despite vigorous workout or dieting. Just to make things a bit clear, some people not on any such device also gained that much mass.


In many cases, some of those women who gained body mass while on it, started losing weight when the device was removed. They need not start a diet or loss program. This continued for a few weeks. This might be a typical case of fluid retention while on this birth control system.


In some cases, the taking of mass starts after the removal of the IUD. The removal of the device also causes a certain hormonal imbalance in the body. Suddenly, the body stops getting its regular dose of Progestin and this make it reacts. The reaction is sometime termed as "Mirena crash" and in some cases it can lead to gain.


Some users, recommends its use together while taking supplements of progesterone. There are no major studies to support these yet.
