Hypothyroidism, or hypothyroidism, may or may not be passed on to children. The pathogenesis of hypothyroidism is varied. There are congenital hypothyroidism, hypothyroidism caused by iodine deficiency, or Hashimoto’s thyroiditis caused by autoimmune abnormalities. If the hypothyroidism is congenital, it is mostly caused by gene mutation and is hereditary. Hypothyroidism caused by iodine deficiency is not hereditary because it is caused by nutrient deficiencies and can be improved with iodine supplementation. Hashimoto’s thyroiditis caused by autoimmune abnormalities has a weak genetic predisposition, but the heritability is not strong, which means that if the mother has Hashimoto’s thyroiditis, the child does not necessarily have it. Hypothyroidism is a serious disease for children, and if your child develops hypothyroidism, it is important to seek immediate medical attention. Otherwise, it can seriously affect the child’s intellectual and physical development, etc.
