underactive thyroid
"I was first diagnosed with hypothyroidism about six years ago. I had gained a lot of weight and couldn't lose it, and I had almost all symptoms (thinning hair and eyebrows, low body temp, lethargy, etc.) During my first year on thyroxine, I lost 50 pounds. It just came off. I was ecstatic.



Slowly, my weight went up. I gained 20 pounds, which was okay because I was still a normal weight. About 3 months ago, my doctor upped by dosage. Suddenly KABOOM - I gained 12 pounds within two months - five of those pounds were gained between last night and this morning. 



That's when I knew something was wrong. I haven't been overeating and I'm active. But the pounds I've gained will NOT come off. No more."
