Reviewed By:

What is hyperthyroidism?

It's a condition in which the thyroid gland produces too much thyroid hormone, often causing a significant increase in your body's metabolism and various symptoms such as nervousness and pounding heartbeat.

Can I get hyperthyroidism from coming into contact with someone who has it?

No. Hyperthyroidism is not a contagious disease and cannot be transmitted to others.

Could I have pass on my hyperthyroidism to my children?

Possibly. Some of the conditions that cause it tend to run in families. But just because you have an overactive thyroid doesn't necessarily mean your children will as well.

Will I always have hyperthyroidism?

A lot depends on how early it is detected and treated. The earlier the condition is diagnosed, the greater the chance that it will be controllable. Many people experience a remission of hyperthyroidism through proper treatment, meaning the condition becomes inactive. In some cases treatment leads to the opposite problem, hypothyroidism, which can be controlled with medication.

Who does hyperthyroidism affect most often?

Anyone can potentially develop the condition. However, it tends to affect women between the ages of 20 and 50 most often.

Can hyperthyroidism affect any of my other conditions?

Yes, if hyperthyroidism is not controlled it can lead to complications including osteoporosis and heart conditions such as atrial fibrillation (a type of abnormal heartbeat) and heart failure.

Can I have hyperthyroidism without having symptoms?

Some people with hyperthyroidism experience no symptoms. But among the many possible symptoms are sudden weight loss, palpitations (pounding heartbeat), muscle weakness, tremors, unusual sweating, trouble sleeping, heat intolerance, skin changes and lighter menstrual periods.

How is hyperthyroidism diagnosed?

Typically it begins with a medical history, physical exam and blood testing. Imaging tests are often used as well.

What can I do to manage hyperthyroidism?

Fortunately there is much you can do to manage hyperthyroidism. Keeping to your treatment plan, getting monitored regularly, maintaining a healthy and active lifestyle, and restricting foods that contain iodine if instructed by your doctor can lessen the severity of symptoms and keep the condition at bay.
