Non-Hormonal IUDs generally do not cause any weight gain. Hormonal IUDs cause weight gain in about 5% of patients. As Mirena is a hormonal IUD, there are chances of weight gain. This weight gain is mainly due to the hormone progestin that causes water retention and bloating.

Some lifestyle changes may be necessary to avoid weight gain, such as exercising regularly, eating healthy, and other weight loss methods.

What is an IUD?

IUD stands for an intrauterine device, which is a small T-shaped plastic device positioned in the uterus to prevent pregnancy. The IUD acts as a foreign body in the uterus and hampers the union of sperm and ovum by causing a reaction in the uterus.

There are two types of IUDs:

Copper IUDs: It is hormone-free and mainly consists of copper. It kills sperm before it reaches the egg. Copper IUDs like ParaGard last longer than hormonal IUDs.

Hormonal IUDs: It mainly releases the hormone progestin into the uterus, which prevents sperm and the egg from uniting. The four common hormonal IUDs available in the United States are:

  • Liletta
  • Kyleena
  • Mirena
  • Skyla

  • Interferes with sperm movement

  • Prevents fertilization of an egg
  • Changes the lining of the uterus to prevent the attachment of a fertilized egg

What are the other side effects of using IUD?

Most of the side effects subside in about three to six months once the body gets used to the IUD.
