““sleeplessness, anxiety, irritability, racing thoughts, a fast pulse, breathlessness, weight loss despite an increased appetite, feeling too hot for no clear reason, and always feeling as though somebody set the thermostat too high, you could have an overactive thyroid. In extreme cases, you might see the classic systems of a goiter (a growth on the thyroid), weight loss, bulging eyes, and an intense staring gaze. Your thyroid is a small butterfly-shaped gland located in your lower neck. When your doctor runs her hands along the base of your throat, she’s checking to see if there are any noticeable problems with the size of your thyroid. But you can’t really tell what’s going on without a blood test. And it can take some adjusting to get your thyroid optimized. The main thyroid hormones—TSH, T3, and T4—all have to be in the right balance. It is estimated that tens of millions of people worldwide (5–25 percent of the world’s population) have thyroid problems. Thyroid problems are more common as we age and they seem to be increasing in the population.””
