The thyroid is an important gland because it produces hormones that act on the entire body and imbalances can lead to very uncomfortable changes. As you know, hyperthyroidism can lead to a variety of symptoms including sweating, fast heart rate, feeling warm, weight loss amongst other problems. After thyroid surgery
, these hormone levels can be drastically affected, and you may now be experiencing effects of having low levels of the hormone that the thyroid produces, also known as hypothyroid. Hypothyroidism can definitely lead to feelings of nausea, vertigo, and dizziness. The best way to tell whether you are actually feeling the effects of hypothyroidism is to be evaluated by your primary care doctor
who can take some blood samples and test the levels of a variety of hormones in your blood. If your doctor finds that you have low levels of thyroid hormones, they may decide to offer you supplemental thyroid hormone in an oral form. The brand name of this medication is synthroid. There are other causes of dizziness and nausea that are possible but less likely which include BPPY, Meniere's disease, and inner ear disorders. Your primary care doctor will best be able to evaluate your medical history and presenting symptoms and decide upon the proper course to diagnose and possibly treat this problem.
