DEAR DOCTOR K: My best friend was just diagnosed with Graves' disease. I'd like to understand the condition and what her treatment will entail.
DEAR READER: Graves' disease is an autoimmune disease that can affect the thyroid gland, eyes and skin. In almost all cases, it causes the thyroid gland to be overactive. The thyroid gland is located in the front of the neck, close to the Adam's apple. It produces hormones that control how our bodies use energy.
