Thyroid surgery is a major operation that takes out one of the very important regulators of bodily functions. The body will no longer produce the T3 and T4 hormones, leading to weight gain, lethargy, and in some cases depression. Not only that, but the surgery also affects the parathyroid glands (which are 4 small glands that are usually found very near or within the Thyroid glans) which can be removed during the procedure as well. The parathyroid gland is responsible for Calcium regulation, and its removal could cause an impairment of Calcium levels, leading to a tingling sensation in your fingers and face, dry skin, and muscle twitching. It is important to know these signs and talk to your doctor if you experience any of them.
If you experience any of the above signs, then you will need replacement therapy for both the T3 and T4 hormones, as well as Calcium and Vitamin D supplements as well. Routine blood tests are done every few months to make sure all your bodily functions are normal and all your nutrients and hormones are within normal levels. In addition, since the surgery occurred near your vocal cords, expect your voice to be a little hoarse for a few weeks, but that should resolve on its own. Finally, the scar is barely noticeable after a year or so and will usually not cause any cosmetic problems.
