lose weight through mirena

Many of us are not familiar with Mirena. For those who are not aware, Mirena is one of the brand names of a birth control system that many women use. It is one of a few long-term birth control options for women. Mirena is a kind of device inserted in a woman’s body that releases small amounts of progestogen levonorgestrel into the uterus. The device looks like a T-shaped plastic framed. As a birth control system, Mirena provides birth control in 5 years span, and among its side-effects is either losing or gaining weight.

One can find the levonorgestrel in Mirena. The levonorgestrel is the active ingredient. It is the substance that is responsible for the contraceptive and other healing effects of the birth control process. Using Mirena will change a layer of the uterus called endometrium that will affect a woman’s ovulation. The contraceptive will also cause the thickening of the cervical mucus, which prevents sperm from passing into the uterus.

How Does Mirena Work?

Mirena is a birth control device that works by releasing levonorgestrel. This hormone thins the lining of the uterus. It also thickens the mucus in the cervix. As a result, sperm has a hard time moving and surviving in the uterus. It prevents pregnancy. The thinning of the uterine lining can also minimize or stop menstrual bleeding.

Mirena Insertion and Removal Process:

During a regular doctor’s visit, women can have Mirena birth control inserted. The insertion takes about five minutes.

Doctors use some tools to help insert the device. But the insertion is not a surgery.

After the start of their period, women should wait seven days to insert Mirena. They also should wait at least six weeks who have just given birth, had a miscarriage, or an abortion.

With the help of a doctor or other trained health provider, you can remove it anytime. If it moves out of place, health care providers must remove Miren immediately. According to Bayer’s Mirena Handbook, eight out of 10 women who have had their Mirena IUD removed can get pregnant within a year. If a patient is not pregnant or faces a problem, she can get a new IUD inserted.

Mirena and the Estrogen Hormone

According to a medical study, a woman usually loses or gains weight when using a birth control system because of the substance called estrogen. However, though some women lose their weight while in the Mirena birth control system, Mirena does not contain the estrogen hormone. Weight loss with Mirena is still considered a myth that has not been proven by any related medical facts and studies.

Mirena’s manufacturer has listed as part of the birth control system’s possible effect is losing or gaining weight. However, there are many examples that the contraceptive did not cause possible changes in the user’s weight. There are no proven and conclusive medical researches yet pointing to Mirena as the primary reason for its users’ weight changes.    

Weight Loss with Mirena

One of the many possible side effects of Mirena is weight loss or gain. Some researchers said that there are many references when women use the birth control system; they gain weight compared to lose it. However, a Brazilian university study published in the journal “Contraception” in August of 2000 used Marina as a test subject for a five-year testing period. The research showed that there were no remarkable increases or decreases in the issue’s weight compared to other issues that use the different forms of a birth control system.

Additionally, in another related study done by the Oregon National Primate Research Center located at the Oregon Health and Science University, a group of monkeys was given different birth control forms. The result showed that monkeys with average weight did not significantly change their weight after they were given the birth control method. According to the result, the obese monkeys did lose weight.
