Hashimoto's thyroiditis is an autoimmune thyroid disease and is not hereditary. However, it tends to cluster in families, meaning if one's parents have a history of Hashimoto's thyroiditis, their offspring have a relatively higher risk of developing the disease. However, this is not absolute heredity; it simply indicates a familial clustering tendency. Treatment for Hashimoto's thyroiditis is relatively effective. If hypothyroidism occurs, one only needs to take lifelong replacement therapy with levothyroxine to maintain thyroid function within the normal range, which has minimal impact on the body. Therefore, there is no need for excessive worry.
