Hyperthyroidism

Overview

Hyperthyroidism occurs when an overactive thyroid gland produces excess thyroid hormone, speeding up the body's metabolism. The most common cause is Graves' disease, an autoimmune condition. With the right combination of medication and monitoring, most patients achieve good long-term control.

Symptoms

• Unexplained weight loss
• Rapid or irregular heartbeat
• Heat intolerance and sweating
• Hand tremors
• Anxiety or irritability
• Difficulty sleeping

Causes & Risk Factors

Hyperthyroidism can be caused by Graves' disease, toxic thyroid nodules, or thyroiditis (inflammation of the thyroid). It is more common in women and in those with a family history of thyroid or other autoimmune disease.

Diagnosis

Diagnosis is based on TSH and free T3/T4 blood tests, along with thyroid antibody testing. A radioactive iodine uptake scan may be used when the underlying cause needs to be clarified further.

Treatment Options

Treatment is tailored to the cause and severity of your condition, and may include:

• Antithyroid medications
• Beta-blockers to control symptoms like rapid heartbeat
• Radioactive iodine therapy
• Surgical referral in select cases
