Thank God I came a cross to this website. I was experiencing these same symptoms since I had inserted mirena. Within 90 days of insertion of mirena, I started having constipation, acid reflux, bloating, belching, anxiety, dizziness, and fatigue. I had been going to my GI doctor and having all types of tests to rule out all possible GI related diseases. All tests results were negative. I went back to my GYN and talked to her about having all these symptoms right after I had mirena inserted. My GYN did not believe me and talked me out of it and said my GI issue is not related to mirena and I should not remove it. I still did not agree with my doctor and continued searching for the cause. I came across this website and I am 100% sure now by reading other people's experiences that mirena is the cause of these GI problems. I have set up an appointment with my GYN to remove my mirena next week. Hopefully I will recover from all the symptoms that I am having right now. I have had my mirena for two years now. If you know please let me know how long it will take to recover from these symptoms after the removal of mirena.
