Should You Test Your Thyroid? Symptoms You Shouldn’t Ignore
By Tharb Faisl
Your Thyroid Controls More Than You Think. The thyroid is a small butterfly-shaped gland in your neck — but it regulates almost every major system in your body. When it’s not working properly, it can throw off your energy, mood, metabolism, hormones, and heart rate.
A simple thyroid blood test could be the key to unlocking chronic symptoms you’ve been ignoring.
