Graves’ Disease

Graves’ disease is an autoimmune condition that forces the thyroid gland to produce excess thyroid hormones, leading to hyperthyroidism. It is the most common cause of overactive thyroid and affects women more often than men. The immune system creates abnormal antibodies that bind to thyroid?stimulating hormone (TSH) receptors, continuously switching the gland “on” and speeding up metabolism.

Common symptoms include unexplained weight loss despite a good appetite, rapid or irregular heartbeat, heat intolerance, excessive sweating, tremors, and nervousness. Many people also develop an enlarged thyroid (goiter) and characteristic eye changes, such as bulging eyes, double vision, or eye discomfort, known as Graves’ ophthalmopathy. If untreated, the condition can weaken the heart, cause bone loss, and trigger thyroid storm, a medical emergency.

Treatment options include antithyroid medicines (methimazole or propylthiouracil), beta?blockers to control heart?rate?related symptoms, radioactive iodine to reduce thyroid activity, and sometimes thyroid surgery. Eye?related symptoms may need steroids, lubricating drops, or surgery in severe cases. With proper therapy and regular follow?up, most patients can achieve stable hormone levels and a good quality of life.
