I had a nasty high TSH as well. 420 then 152. I'm also fairly young. Only 30. I suspect that the younger you are the more likely you are able to tolerate the symptons and this leads to extra high TSH levels.
Who knows. Good luck getting this under control.
Peace!
You have severe hypothyroidism due to Hashimoto's. this is also likely causing the high cholesterol. based on what you describe -you need a higher dose of synthroid (likely 100-125mcg / day ) . The ultrsound may help identify any nodules, but a goiter (large thyroid) is expected with this history. The key is getting on the proper dose of thyroid replacement medication.
Just wanted to give some more info from my tests that came back High or Low:
My T4, FREE is 0.3L (range is .8-1.8)
RDW 15.7H (range: 11.0-15.0)
Carbon Dixoide 19L (range 22-33)
Albuim 5.2H (range: 3.6-5.0)
Cholesterol 350H (range 125-200)
LDL Cholesterol 274H (range <130)
CHOL/HDCL Ratio 6.6H (range <or= 5.0)
Thank you thank you thank you!!
