Thyroid disorders can have a hereditary component, especially if they’re due to an autoimmune disorder like Hashimoto’s thyroiditis, the most common cause of hypothyroidism. You may be at a higher risk if there’s a family history of thyroid problems. However, environmental factors, lifestyle choices, and other health conditions also play significant roles in thyroid health. Knowing your family history can be a key factor in the early detection and proactive management of thyroid conditions.
