Hello! I have been banded for almost 3 years now.. 1.5 years after banding I got the mirena iud inserted (I have no kids..insertion sucked but I managed and my inusarance paid for it) anyhow.. I am personally very sensitive to hormones and the iud made me come off of my good weight loss I was having and I gained about 7 pounds.. could not shake it and I had mood swings.. acne etc... it made having my lapband a personal hell because I could never get an actual fill because my band kept tightening and never lossening again till I got so closed band wise I couldn't eat or drink.. I had the fill yanked right along with the mirena.. I just replaced it with the paraguard and have had my fill put back in.. I lost 2 pounds within the first few days of it being gone... so it may work for some people but if your sensitive to hormones and have a band it may effect you or not... I kept it in for 13 months.. if the paraguard doesn't work... my iud journey will coe to an end because between the band and the iud.. the band wins! goodluck!
