Researchers have identified a compound that prevents overproduction of thyroid hormone, a finding that brings scientists one step closer to improving treatment for Graves’ disease. In Graves’ disease, the thyroid gland never stops. Thyroid-stimulating antibodies bind to receptors, activating them to keep the thyroid hormone coming and coming — like a broken traffic light stuck on green — and causing the body problems in regulating energy, controlling other hormones and maintaining cells throughout the body.
