Acquired Hypothyroidism In Children
WHAT YOU NEED TO KNOW:
What is acquired hypothyroidism?
Acquired hypothyroidism is a condition that develops when your child's thyroid gland makes little or no thyroid hormone. Thyroid hormones help control body temperature, heart rate, and how your child gains or loses weight. Thyroid hormones play an important role in normal growth and development of children. Acquired hypothyroidism usually affects children starting at 6 months of age. Some children who have hypothyroidism when they are born only show signs and symptoms much later in childhood.
What causes acquired hypothyroidism?
The following conditions may cause or increase your child's risk of acquired hypothyroidism:
- Autoimmune disease: A problem with your child's immune system may make his body attack his thyroid gland. Autoimmune thyroiditis is the most common autoimmune disease that causes acquired hypothyroidism.
- Family history: Your child's risk is greater if a family member has hypothyroidism or an autoimmune disease.
- Medicines: Certain medications can cause hypothyroidism. Ask your child's healthcare provider if any of the medicines your child takes can cause hypothyroidism.
- Treatments: Radiation therapy used to treat cancers of the head and neck can destroy your child's thyroid gland. Thyroid surgery makes him more likely to develop hypothyroidism.
- Other diseases or conditions: An enlarged or swollen thyroid, lumps caused by infections, or thyroid cancer can affect how your child's thyroid works.
- Low iodine levels: The thyroid gland uses iodine to work correctly and to make thyroid hormones.
