I have had the essure in since late August. I have not had one problem. I have not been back yet to have the coils checked to see if the scar tissue (which is supposed to grow) has healed properly. My doctor gave me tons of information about the pros and cons, and I was clearly aware of the risks of the procedure – perforation, among other more serious ones, which could still happen. But I willingly took the risk. Headaches from the essure are often caused from a switch from a hormonal type of birth control to a non-hormonal one. I don’t think this is a conspiracy or a bad product. I trust my doctor 100% and she noted out of all the procedures she had done throughout the years, she only had a few people for whom it did not work and it was removed. I feel sorry for the women who are experiencing problems, but the majority of women are not. The information about the nickel allergy is easily accessible via the pamphelt and information online. Either women are not doing their research about their own choice of birth control or the doctors are not doing their jobs informing the patients. Either way, if a half a million women have experienced success, then just like any other form of birth control, essure is only appropriate for certain women. The most common complaints are weight gain, fatigue and depression. Most women in their 30s, 40s, and 50s experience these symptoms at one point or another. How can they possibly narrow it down to essure causation?
