Firstly go here (<-----Click this!) and see what a Minti member posted about the IUD's
The following comments, coming from a man, might sound weird but I am not quite the normal run of the mill male, I actually was so interested in the workings of the human body, that I did a lot of reading about the topic and researched a lot into hos a ladies body works ...so.here goes......
My understanding on your desire is that now you have finished having kids, had your tubes tied so now you want to be rid of the monthly period. Well there are few truly effective methods to achieve this goal that are not going to cause you problems in the long run.
IUD's are about as effective as any other form of contraception. The big issue you need to consider with IUD's is the chances of something going wrong with the implant. There have been cases of ladies needing emergency surgery to remove an IUD because of infection, the IUD growing into the uterus walls etc.. IUD's also are known in many cases to increase bleeding, and sometimes cause toxic shock symptoms. I know a few ladies who had emergency surgery to remove one of these after becoming quite ill....Personally I think IUD's are too dangerous...Think about it, you are asking a doctor to place a foreign object into the single most sterile environment in your body, and this very act can open you up to primary and secondary infections and medical complications that are potentially life threatening.
Some ladies prefer the injection Depo Provera. This is a hormone injection that lasts about 3 months, and in a lot of cases stops the periods altogether. However one main side effect that is noted, is retaining water causing weight gain and puffiness around the body. This does not happen with everyone but does happen, although with regular exercise and good diet, this side effect can be dramatically reduced.
By far, the most simple way to prevent periods is the normal oral contraceptive pill. I know many ladies don't like taking it, but it is generally the safest way to prevent periods. Your doctor will suggest the right formulation and strength for your body (as peoples hormone levels etc can effect the pills ability to prevent a period).
To be honest, there is no 100% foolproof or effective way to stop a period. The only two ways I know that are 100% effective are Total Hysterectomy or Menopause. The first would not be performed without a threat to your health being present (ie Cervical cancer, Ovarian cancer etc..), and the latter only happens after you reach that time in your life or in some cases acute stress can bring on early menopause.
Unfortunately you are facing the very same dilemma that women since the dawn of time have been demanding....There are methods that can work, but in all reality, most methods come with some form of risk. You just need to ask yourself...Is the risk worth it?
