Any success with Hypothyroidism.Bipolar Disorder?

I'll be honest, I don't know much about hypothyrodism, but as for bipolar/borderline medication, I do have experience with that (I have BPD). I'm not sure what medication you're taking but there are some that the side effects are weight gain. I've been on just about every medication under the sun, and honestly, unless the actual medication just made me want to eat 24/7, or I just never felt full (which I've never had that feeling, but I know there are people who have described that feeling with certain medications), if you've found something that works for you well, stay with it. It's SO hard when we're trying to find something to level out chemical imbalances, that it's hell having to hop around from one to another (I'm probably preaching to the choir here, too.)

Hypothyroidism really slows down the metabolism, but are you on daily throid meds? Are they checking your TSH, T3, T4 levels at least 2-3 times a year? I've been able to lose weight since my thyroxine levels were stabilised in the normal range with meds. Before that, I couldn't lose hardly any weight at all..
