Thyroid Disorders

What type of synthetic thyroid hormone should I take?

DEAR DOCTOR K: I have hypothyroidism and take synthetic thyroid hormone. Is it OK to switch brands or switch to a generic?

DEAR READER: It's OK to switch, so long as your doctor monitors your thyroid blood tests. It is very important to get your dose right: Your thyroid gland influences your metabolism. It affects everything from body temperature to body weight, energy level, even fertility.

What is Graves’ disease and how is it treated?

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.
