Hypothyroidism means that the thyroid gland does not make enough thyroid hormone. Low levels of this hormone can cause many body functions to slow down.
Failing to grow normally is the most common sign in children. Hypothyroidism can also cause your child to feel sluggish, gain weight, and have a poor memory. It may also be hard for your child to focus his or her attention. The symptoms of the disease can be similar to depression.
Hashimoto's thyroiditis is the most common cause of hypothyroidism in children. In this condition, the body's immune system attacks the thyroid gland. The thyroid has to work harder to make enough hormones. This can cause an enlarged thyroid gland that can be seen at the front of the neck. This is called a goiter.
