I have the same problem to exactly. Gained 30 lbs, enlarged thyroid, mood swings, eating well, exercising borderline normal numbers... No help yet. I got further testing done by an R.E. but it didn't help. So... I am nowhere with this really.

Most of my weight is abdominal and I have endometriosis and adenomyosis, so bloat is a BIG problem for me, but still, it's frustrating. That's for sure.
