Hyperthyroidism is also known as an overactive thyroid. It is a disease caused by the overproduction of thyroxine, a hormone secreted by the thyroid gland. Thyroxine controls the rate of your metabolism, so the excessive volume of it can make your metabolism much faster, leading to irregular or rapid heartbeat, weight loss, irritability, and sweating.
If you are experiencing the above symptoms, you should see a doctor. Other signs include nervousness and swelling at the base of your neck. You must completely describe the changes you've observed, for some symptoms may be associated with other conditions.
If you ignore hyperthyroidism, it will become very serious. But in most cases, patients respond well once it is diagnosed and properly treated.
