Several factors can cause abnormal TSH levels in children, including:
Congenital Hypothyroidism: A condition present at birth where the thyroid gland does not produce enough thyroid hormone. Autoimmune Thyroiditis: An autoimmune disorder where the immune system attacks the thyroid gland, leading to Hashimoto's Thyroiditis or Graves' Disease. Iodine Deficiency: Lack of sufficient iodine in the diet, which is essential for thyroid hormone production. Genetic Disorders: Certain genetic conditions can affect the thyroid gland's function. Medications: Some drugs can interfere with thyroid function and alter TSH levels.
