I am 38 years old and had my mirena put in in January 2007. Since than I have gained 40lbs. I have been extremely frustrated because I have been eating well and run all day bc I have a home day care - 6 children under the age of 4 plus 3 have autism. I have a serious post surgical spine condition and all the specialists keep telling me to lose weight. It seems the more active I am and healthier I eat I still am gaining. I have even been using Xenical/orlistat prescribed by my doctor and my belly just seems bloated and getting bigger.I feel less in control of my emotions than I did before the mirena insertion and I am convinced it is the mirena. My husband is on his way to have a vasectomy and I am going to have it removed as soon as I can get an appointment. Makes sense though in hindsight - put a foreign hormone in your body and it will fight back. I have not had any bleeding or a period since January. My breasts are often tender and have chronic IBS - was not that way before January .....can't wait to have it removed .....horrible side effects - I think the emotional side effects will last long after I have it removed.
