The thyroid is located in the neck just above the collarbone. It helps control metabolism and calcium levels in the body. Hyperthyroidism, or an overactive thyroid, can lead to weight loss, fatigue, nervousness, rapid heart rate and intolerance to heat. Hypothyroidism, or underactive thyroid, is often characterized by depression, fatigue, weight gain, muscle cramps and elevated calcium levels.
Causes of thyroid disorders
Some, but not all, thyroid disorders are caused by nodules growing on the thyroid or thyroid tumors, or disorders related to the associated parathyroid gland.
Common treatments for thyroid disorders
Thyroid biopsies and thyroid ultrasounds are used to examine the thyroid and diagnose thyroid problems.
