Get to know this a small, but mighty, butterfly-shaped gland located at the base of the neck. The thyroid influences the function of many important organs, including the heart, brain, liver, kidneys, and skin.
Hyperthyroidism, or overactive thyroid, is when your thyroid gland makes more thyroid hormones than your body needs. If left untreated, hyperthyroidism can cause problems with the heart, bones, muscles, menstrual cycle, and fertility.
Hypothyroidism, or underactive thyroid, is when your thyroid gland doesn’t make enough thyroid hormones. Thyroid hormones control the way the body uses energy, and without enough, many body functions slow down.
Check Your Neck
There are a number of thyroid tests to check how well your thyroid is working and to find the cause of problems such as hyperthyroidism or hypothyroidism.
