underactive thyroid
"I am a type l diabetic 45yrs of age. I have been on Synthroid for several years (now about 13) since I became a diabetic. I had a hysterectomy two years ago. I have been on Vivelle patches, Estradol, Premarin and for the longest Enjuvia and just recently changed to Estragel. For the last six months I have been experiencing lifeless hair, breaking off. I have never experienced anything like this. I am very frustrated."
