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, growth, and gaining or losing weight. Thyroid hormones play an important role in the 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 show signs and symptoms much later in childhood.
