causes of abnormal thyroid scan
Thyroid disorders can range from a small, harmless goiter (enlarged gland) that needs no treatment to life-threatening cancer. The most common thyroid problems involve abnormal production of thyroid hormones. Too much thyroid hormone results in a condition known as hyperthyroidism.ince your body's energy production requires certain amounts of thyroid hormones, a drop in hormone production leads to lower energy levels. Causes of hypothyroidism include: 1  Hashimoto's thyroiditis: In this autoimmune disorder, the body attacks thyroid tissue. 2  The tissue eventually dies and stops producing hormones.
