I was diagnosed with a thyroid issue back in 2007. I have been on levothyroxine ever since. Before the WLS I was taking 150 mcg. A few months after surgery the doc decreased it to 137 mcg, now this past week she decreased it to 112 mcg's. My question for anyone who has had something similar is, does this ever completely go away so that you are no longer required to take meds for it?

Good question! I'm down to 100 from 175 and I wonder that too.

Hashi’s is auto-immune based, so it is extremely common to have dosages lowered if you’re not having a flare up. Restricted calories and weight loss will reduce inflammation which can cause thyroid resistance. I’ve seen a few studies done where longer term restricted calories can actually improve thyroid function, so it does make sense.
