The Mirena can be an excellent way to improve menorrhagia (excessive menstrual bleeding
). The hormone in it, Progesterone, thins the uterine lining making periods
lighter and in 20-30% of women there periods end after 1-2 years (which some women like, some don't). Also, it won't affect your blood pressure.
However, there are other ways to address menorrhagia. Talk to your ob/gyn about all of your options and decide which is best for you.
