Question: I have been diagnosed with hypothyroidism, and I am concerned about some of my symptoms. Sometimes, after I exercise, I notice I am very hot and dizzy, and feel that my body has a hard time "coming down." Is this normal with hypothyroid patients?
Dr. Hibberd's Answer:
The thyroid is the "boiler" for our metabolism. Without adequate thyroid, normal cellular function is impaired and may result in fluid accumulation, blurred vision, diabetes, lipid disorder, low heart rates, fainting, and eventual heart failure if left unaddressed.
It is very important to further evaluate exercise-induced dizziness. Hypothyroidism is associated with other metabolic disorders such as diabetes and adrenal insufficiency, so evaluation under physician guidance is important.
Always hydrate yourself before and during your run. Wear loose-fitting clothing that allows for adequate cooling when running.
It sounds like time for re-evaluation by your primary care physician, and probably an evaluation for other causes of dizziness and nearly fainting. Expect an EKG, lab work, and possibly an exercise stress test evaluation under cardiology supervision if no obvious cause is clear on your initial evaluation.
