What differs hyperthyroidism from chronic fatigue syndrome?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My symptoms include difficulty concentrating, brain fog, difficulty swallowing and sleeping, fatigue, and irritability. The doctor suspected thyroid disease since my grandfather had thyroid issues. I have reviewed my laboratory results with his. My TSH is 0.325 mIU/mL, T4 free is 1.47 ng/dL, and T3 was not detected. All other laboratory results were normal except for vitamin D 25-hydroxy, which was 27.3 ng/mL. He stated that the results revealed no thyroid issues. I must be seeing something different, but would not such a low TSH lead to the possibility of hyperthyroidism?

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

It appears that you have chronic fatigue syndrome. Yes, your TSH (thyroid-stimulating hormones) is slightly low, but because your T4 (thyroxine) is within normal limits. Therefore, you likely do not have hyperthyroidism currently. You can, however, repeat your thyroid function test after three months to ensure that your thyroid function is normal. Get enough sun exposure every day. Try to do graded exercise, such as 5 minutes per day, and gradually increase it as you become more comfortable. Yoga and meditation can help you overcome insomnia and fatigue.

I hope this helps.

Thank you.
