Thyroid problems have become widespread, especially among women. There are basically two main thyroid disorders:
- Hypothyroidism: Hypothyroidism is characterized by production of thyroid hormone below the normal level. It often results in weight gain and is the most common form of thyroid disorder.
- Hyperthyroidism: This disorder is characterized by excessive production of thyroid hormone due to an overactive thyroid gland. Symptoms include increased heart rate, depression, weight loss and cognitive slowing. Medications include the use of radioactive iodine and thyroid surgery.
