I had my mirena inserted in March 2008 and started having severe acid reflux issues in January 2011, as well as digestive issues that have been diagnosed as IBS. My gastroenterologist doesn't believe they have anything to do with my mirena, though she can't tell me what is causing the issues. Acid reducers (2 Prevacid a day) and fiber seem to help some of the time, but never quite do the trick. Has anyone else also experienced digestive issues such as cronic gas, constipation, or diarrhea since having their mirena?
