I have vasovagal syndrome and one of the symptoms is loss of mental acuity and energy in general. An anesthesiologist asked me if I had been prescribed thyroxin, which I have not, and it made me wonder whether hypothyroidism could be connected to the vasovagal syndrome. I had blood tests done a few months ago and T3 and T4 were within the normal range, but I understand that these two tests are not always very reliable. There is a lot of autoimmune incidence in my family. I would be very interested in your opinion. Thank you
Hi, Thanks for consulting Chat Doctor ! As I can understand, you are concerned about whether you have hypothyroidism or not. You need to undergo TSH test as well in addition to T3 and T4. Based on the results we can order other tests like thyroid autoantibodies to confirm diagnosis. Hope I have answered your query. Let me know if you have any clarifications. If not, you can close the discussion and rate the answer. If you like my answers and wish me to answer in the future, bring it to my attention
