What Causes Tiredness, Hand Tremors And Abnormal TSH Value?

Posted on Wed, 14 Oct 2015

Question: I am 66 and have been on sythroid for 35 years. In July my medicine was lowered from 150 mcg to 137.5 mcg and I have within the last week started feeling extremely tired and my pressure went up several times over the weekend. on Monday AM my hands were shaking and I was not thinking right. I went to the doctor thinking I could possibly have something going on with my heart. EKG was normal, the ran different blood tests and the only two that were adnormal was TSH (they have lowered my medication to 125 mcg and vitamin D which they have instructed me to take 1 Vitamin D3 (1000) per day. Could this be the cause of the changes? I have never had this feeling before and am still working daily.

I have never had heart issues and appear to not have any now. Was wondering if my increasing age has anything to do with this problem and the continuing decrease in medication. I have never had symptoms while taking sythroid in the past.

Brief Answer:
Thyroid

Detailed Answer:
Taking higher than necessary synthroid doses can potentially cause the symptoms you had.

Yes sometimes with age, the synthroid dose requirement can go down. This is particularly true if there is weight or muscle mass loss.

Once your TSH and Free T4 are in the target range, and it stays that way for several weeks one can consider your thyroid to be stable and well regulated.

If despite this, your symptoms persist then it is extremely unlikely that they are due to a thyroid problem.
