The Thyroid Gland
The thyroid gland produces hormones that regulate metabolism, energy levels, and many other bodily functions. Thyroid disorders can significantly impact quality of life.
Common Thyroid Conditions

Hyperthyroidism
An overactive thyroid that produces too much thyroid hormone. Symptoms include weight loss, rapid heartbeat, and anxiety.
