Pediatric Endocrinology - hyperthyroidism

​​​​​​​​Hyperthyroidism results when the thyroid produces abnormally high levels of hormones. 

In children this condition is often caused by Graves' disease, in which the immune system causes the thyroid to be overactive. 

Symptoms include pounding heart, sweating, trembling, weight loss, eye protrusion and swelling in the neck from an enlarged thyroid (goiter). 

Marshfield Clinic has pediatric specialists trained in the diagnosis and treatment of hypothyroidism.


Your doctor will work with you and your child to determine the best course of treatment based on the particular condition.


Beta-blockers, while not a cure, can decrease activity in the thyroid helping to reduce symptoms.

Antithyroid medications can help to keep the thyroid from producing excessive hormones but again do not cure the condition.

Radioactive Iodine Treatment

In some cases, your physician will recommend the consumption of a solution that includes radioactive iodine. 

The iodine kills the overactive thyroid cells and the symptoms go away over time. Any excess iodine is safely passed through the urine.


In more instances, where the child cannot tolerate the medications and radioactive iodine is determined not to be an option, a surgeon may opt to remove the thyroid gland.

Hormone therapy

After treatment, your physician may recommend hormone therapy to make sure your child has the proper level of thyroid hormone in their body.
