I’m currently on 88mcg of Levo. I have had no weight gain through the process of RAI, replacement, etc. BUT, my "lower belly", is extremely bloated. I’m thin and when I turn to the side, it’s like I had a water balloon in my belly. Although the scale shows no weight gain, I have never had this and I have had 3 kids. When I shuck in my stomach from the side it looks like I’m 3 months pregnant (I’m Not;) All I can relate this to is hormones? I’m 32….so is it the thyroid adjusting? It is terrible. It has been like this for 1 month. Nothing helps it. Anyone had this after RAI?
