A few years ago I had an infection in my thyroid needle biopsy to drain the fluid. I gained lots of weight over this time. After I had a child I began losing weight which I at first thought was because I was breast feeding, but it came that I was losing so much that I weighed less than my skinny teenage daughter. I began to have memory loss and was exhausted most of the time. I went to a health fair and had my THS tested resulting in it being extremely low (healthy is above .25 and mine was .02) meaning that my thyroid was over active. My T cells are normal. Which means my thyroid is normal, because THS comes from the petuitary gland I m assuming something might be wrong with it. My doctor doesn t know much about it all and didn t know what to do. Help?!
