Congenital hypothyroidism is a condition present at birth where the thyroid gland does not produce enough thyroid hormone, which is crucial for normal growth and development. Symptoms in newborns may include poor feeding, jaundice, constipation, and slow growth, while older children may experience delayed development, learning difficulties, and fatigue. Early diagnosis and treatment are vital to prevent developmental delays and other complications. Treatment typically involves daily thyroid hormone replacement therapy, which helps normalize hormone levels and supports proper growth and brain development. The benefits of treatment include improved growth, better cognitive function, and a reduced risk of long-term complications. Treatment is usually lifelong, with regular monitoring to adjust hormone levels as the child grows.
