I am 22 years old and was diagnosed with hypothyroidism a year ago. The first signs I had was weight gain and loss of hair. I was put on syntroid but I had no luck with it. Then they put me on Armour Thyroid once I got up to 120 mg I felt better but as time has passed I have begun to feel bad again and my symptoms have came back. The DR says my levels are fine but I don't feel fine. I am gaining weigh and I watch every bite that goes into my mouth and workout six days a week for 75 minutes a day. I went from 128 to 138 in a matter of three months. Does anyone have any advice? I'm getting stressed and need something soon.
