What is Hashimoto's disease?
Hashimoto's disease is a problem with your thyroid gland. The thyroid gland is located in the front of your neck, just below your Adam's apple. It makes hormones that control metabolism, the pace of your body's processes. Metabolism includes things like your heart rate and how quickly you burn calories. When you have Hashimoto's disease, your immune system begins to attack your thyroid gland, causing it to become swollen and irritated. When this happens, your thyroid can't make hormones as it normally does.
