Congenital Hypothyroidism (CH)

Primary congenital hypothyroidism (CH) is a condition that affects the body's thyroid gland, a small organ in the lower neck. People with CH are unable to produce enough thyroid hormone, a chemical that is essential for healthy growth and development. If left untreated, CH can cause sluggishness, slow growth, and learning delays. However, if detected early and treatment is begun at that time, individuals with CH often can lead healthy lives.
