I've just been told by GP that my TSH is 20. No other blood tests related to thyroid have been do, but my GP says i'm hypothyroid and thyroxine will sort it out. I'm concerned as this seems a very simplistic view. Has anyone else had a similar experience. Could a high TSH be anything else other that hypothyroid?

  • Usually a more complete line of tests are performed including thyroid antibodies, Free T3, Free T4 and Total T4. However, a TSH of 20 by itself indicates hypothyroidism.If you have any complications of hypothyroidism, such as hypertension, I would suggest finding a qualified endocrinologist.

  • As Dxd said, your doctor is probably right - did they measure levels of any other thyroid hormones? Extremely high TSH, accompanied by low free T3 & T4 is indicative of primary hypothyroidism. The thyroid gland is unable to function at an optimal level. The pituitary gland senses that not enough T3 and T4 are being produced, so it increases its stimulation to the thyroid. But if the thyroid is malfunctioning, the increase in TSH will have no effect. So it sounds to me as though your doctor is correct.
