Understanding Hyperthyroidism in Children: Symptoms & Causes

Hyperthyroidism (or Graves disease) in children is caused by excessive amounts of the thyroid hormone thyroxine (T4) in the bloodstream. The symptoms that show up in children have a big impact on their lives.

History

• Hyperthyroidism is not a common occurrence in children. It only affects 1 in 5,000 children, usually between the ages of 11 and 15 (J Clin Endocrinol Metab. 1987 Jun;64(6):1241-5).

Types

• Hyperthyroidism in a newborn baby can be fatal, and the disease in older children might have troubling symptoms and consequences.

Features

• Symptoms of hyperthyroidism in children may include restlessness, diarrhea, flushed, moist skin, rapid heart rate, high blood pressure, shaky hands and poor weight gain.

Identification

• A blood test can be done to confirm a diagnosis of hyperthyroidism.

Prevention/Solution

• Treatment for children with hyperthyroidism may include medication, removing part or all of the thyroid and long-term monitoring in case symptoms return.

Warning

• Since the possibility exists for hyperthyroidism or Graves disease to return, it is important for the affected child's thyroid levels and symptoms to be monitored regularly.
