Hyperthyroidism

There are various known causes associated with hyperthyroidism. Learn more about them below:

• Grave's disease: Perhaps the most common cause of hyperthyroidism, Grave's disease is defined as an "autoimmune" or "self-attacking" disease where proteins (antibodies) produced by our own white blood cells overstimulate the thyroid gland to produce excess thyroid hormone which accelerates the body's metabolism. It was named after Doctor Robert Graves and accounts for at least 70% of cases 
  
• Eye inflammation: Grave's disease can cause swelling and inflammation of the eyes as well as sensitivity to light and blurring or double vision
  
• Toxic multinodular goiter: As we age, multiple nodules may develop in the thyroid gland which could produce excessive thyroid hormone
  
• Toxic nodule: A single thyroid nodule may produce excessive thyroid hormone 
  
• Excessive iodine ingestion: Drugs such as amiodarone that is high in iodine concentration could cause hyperthyroidism in certain patients
