Running with Hypothyroidism?
Dr. Roberts, I was recently diagnosed with hypothyroidism. My TSH level was around 15 before I began taking thyroid medication. My doctor says that I have likely been dealing with sub-optimal thyroid levels for many years. For the past few years I have been a pretty dedicated runner, logging about 20 to 30 miles a week. I was obviously frustrated with the weight gain and sluggishness that I now realize was because of my thyroid. Do I need to change my training now that I am getting a thyroid medication to regulate my TSH levels? What kind of concerns or possible problems should I be on the lookout for? Are there any supplements I can take or things I can do to maximize my training and performance? Thank you–Dave Dave, Hypothyroidism (underactive thyroid) is a common problem in the general population and probably affects many runners. It is more common in women, but I have many male patients who are affected like you, usually in the 50-plus age group. Thyroid hormone is the primary determinant of the overall metabolic rate in the body, and by accelerating the metabolic rate of most tissues, it increases heat production. It also plays a role in normal growth and in the development and function of the nervous system. Treatment with synthetic thyroid hormone is simple, safe, and effective. As you initiate and continue treatment with thyroid replacement hormone, you will most likely find it easier to lose the weight you added and find physical activity like running more enjoyable. I know of no reason to change your training habits or to stop running because you developed hypothyroidism. Once optimally treated, you will most likely note an improvement in your performance and resolution of the sluggishness. Hope this helps. Cheers, Bill Have a question for the Sports Doc?
