What Causes Elevated TSH Levels, Body Ache And Chills After A Thyroid Surgery?

Hi, I recently had surgery to remove two nodules from my thyroid. They removed about 2/3’s of the thyroid. Blood tests showed my TSH jumped from 1.6 to 3.32. I was having all kinds of issues that seemed consistent with hypothyroidism. Initially they told me I was within the normal range but I was feeling terrible with body aches, joint pain, constant chills as well as severa other things. In my research that sounded like hypothyroidism. Yet the dr kept saying I was in normal range. I have been doing some reading that debates what normal range is as well as mentioning optimum range. What are your thoughts on this? If a patient is within normal range but having symptoms is it possible that is not normal for the patient and medication should be considered?

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

TSH (thyroid stimulating hormone) is produced by the pituitary glands in the brain and regulates thyroid hormone levels in the body. In thyroid disorders when thyroid hormone production is reduced TSH levels increases (low T3/T4 causes high TSH) and vise versa increased thyroid hormone production causes reduced production of TSH (high T3/T4 causes low TSH). This is called negative feedback regulation. But in pituitary disorders low TSH may causes low thyroid hormones. In certain thyroid disorders (euthyroid sick syndrome) patients may have hypothyroidism even with normal THS. Therefore, TSH alone may not be enough to diagnose hypo- or hyperthyroid conditions. To evaluate your condition along with TSH you may need T3, T4 and thyroid binding globulin levels.

Hope I have answered your query. Let me know if I can assist you further.

Thank you.
