Mirena, I have given it a beautiful name: Mirena. It is like an enchanting and beautiful young woman, in the eyes of doctors it is a powerful tool for the treatment of endometriosis, excessive menstruation and contraception, as beautiful as a bouquet of flowers. It is also like a vain and sensitive young woman, in the eyes of the patient, it drapes the body of the drug, which may bring scarce or even missing menstruation, and the drug is released in the body all day long, making it impossible to sleep. So what is this young woman? Why is it good? And why does it cause confusion to the user? IUD development of more than half a century, Manuel can only be considered a latecomer, in the days of 10 years, it’s completely changed the concept of people for the IUD, before the IUD is free, a wear is a lifetime, even some grandmothers are seventy years old, only to remember that there is a ring in the body. This is because the previous IUDs were inert, i.e. drug-free. In contrast, there is a magical slow-release system in Manuel, which releases a progestin (levonorgestrel) that works steadily for 5-7 years. This relies on scientific and technological advances and is the only intrauterine slow release system so far. Some may say that doctors are bragging again and advertising to manufacturers. In fact, in the doctor’s circle, we often talk about the efficacy of the Mannorrhea and think that the person who invented this slow-release system should really win the Nobel Prize in medicine, it makes many women who suffer from painful menstrual cramps every month spend their days in peace, it makes women who have a lot of menstrual flow spend their months in peace. Isn’t it a miraculous thing. In fact, just as there are two sides to everything, the drug Mannorrhea can bring about extraordinary therapeutic effects, but it can also produce confusing side effects. Levonorgestrel is a synthetic progestin. Its main role is to inhibit the growth of the endometrium, which can cause excessive menstrual bleeding, endometrial polyps, and even endometrial cancer, in addition to disobedient endometrium can grow in the uterine muscles and in the pelvis, causing adenomyosis and endometriosis. The effect of levonorgestrel is both internal and external, so it can inhibit both the endometrium in the uterus, which leads to reduced menstruation, and the endometrium outside the uterus, which leads to the shrinkage of endometriosis foci. That’s how it works as a treatment. As I said at the beginning, Mirena, despite its beauty, is also vain and sensitive, so it takes time and understanding to make it a “good daughter-in-law”. First of all, understanding the therapeutic effects of Mirena, one should deduce the confusion it may bring: reduced menstrual flow or even amenorrhea. There are many women who cannot accept amenorrhea, as if without monthly periods, the toxins in their bodies cannot be eliminated. But to put it another way, if the lining of the uterus does not grow each month and there is no toxicity to expel, then what is so terrible about amenorrhea. So first of all, you need to understand. The other thing that takes time is the break-in period between the medication and the body, during which there will be conflicts, which will manifest as “dripping bleeding” for 3-6 months, or even longer. This process is necessary and cannot be completely avoided. Sometimes doctors will use hemostatic pills, oral contraceptives, etc. to reduce the bleeding. But it only shortens the bleeding time, and it still depends on time to hope to get a small amount of menstruation in a cycle at once. I have said a lot of good and bad things about Mannorrhea, but it is like accepting one person, there are good and bad sides to everything, understand and accept it, and take the big picture into consideration. I would like to dedicate this article to those women who are struggling with the idea of Menstruation.
