Hello doctor,

I have been treated for anxiety disorder for the past eight years. They are now suspecting a thyroid problem. I have lost more than 25 lbs in the last eight weeks which has triggered the doctors to look closer into this. I have elevated anxiety, shaky and unsteady, high pulse rates especially in the morning 100 - 115 beats per minute, and fatigue. I am currently taking Xanax. I have attached a couple of blood tests that I have on hand. Please let me know your thoughts.

Welcome to icliniq.com.

I just read your query and saw the results which you have attached (attachment removed to protect patient identity) and it appears to be an absolutely normal thyroid function test results.

As your TSH (thyroid-stimulating hormone) is within the normal range, your thyroid function is normal. The slightly high T4 is not responsible for your symptoms since it is just a variable component, so as long as your TSH is normal your thyroid function is normal. Although you have impaired blood sugar levels, since HbA1c (glycated hemoglobin) is normal therefore just diet control will help. Take low carbohydrate and low-fat diet with daily 30 minutes of walk. You could benefit from a prior ECG (electrocardiogram).

I would suggest taking tablet Bisoprolol 2.5 mg once daily for your tachycardia and anxiety. It will decrease your heart rate to normal levels and help you with your anxiety as well. Try also to do yoga and meditation daily.

I hope this helps.

Thank you doctor,

Is the TSH level you are referring to the one that I have attached as TRAB (TSH receptor binding antibody)? The level says 36.5 and the range are 16.0. Please suggest.

No, what I mean is the TSH and that is normal. However, what you mentioned right now TRAB is the antibodies to the TSH receptor binding which even if high does not mean a thyroid gland dysfunction.
