Mirena is a type of intrauterine device that helps prevent pregnancy for up to five years. It works by releasing progestin, which is a synthetic form of the hormone progesterone. This hormone helps prevent the sperm from fertilizing the egg by thickening the cervical mucus. It also suppresses ovulation partially.
Mirena is effective and easy to use, which is why it has become very popular among young women. However, there have been a number of IUD birth control problems reported. Below are some of the problems that have been reported by women who have used Mirena:
Holes In The Uterus (Uterine Perforation)
The Mirena IUD can perforate, or tear a hole in the uterus. If that occurs, then the device will need to be removed because it will not be able to prevent pregnancy. There is also the chance that the Mirena device will move outside of the womb and damage other organs.
This is one of the most common IUD birth control problems. In fact, it is estimated that 12 percent of women develop ovarian cysts while they are using Mirena. A cyst is a fluid-filled sac that develops inside of the ovaries. In most cases, cysts are harmless and go away without medical treatment. However, some patients are required to have their cysts surgically removed.
Many women notice their menstrual cycles change after they get Mirena. Some women have painful, irregular periods for the first six months after implantation. A woman may also stop getting her period completely.
It is estimated that 50 percent of the women who get pregnant while using minera will have an ectopic pregnancy. An ectopic pregnancy occurs when the fertilized egg grows outside of the uterus. An embryo cannot survive outside of the uterus. This pregnancy also threatens the life of the mother.
Pelvic Inflammatory Disease
Pelvic inflammatory disease is a type of infection that affects the reproductive system. It is usually caused by gonorrhea or chlamydia. Even though PID is not caused by Mirena, if a woman has a genital infection when the device is inserted, then she will be more likely to develop PID. PID is a very serious condition that can lead to infertility or death if it is left untreated.
The Mirena expulsion rate is around 2.9 percent for women who use it solely for contraceptive purposes. If Mirena is used to treat a condition, such as endometriosis or uterine fibroids, then the expulsion rate ranges from 10 to 13 percent.[hr]
