Patient's question:
My thyroid function has gradually declined, and hyperthyroidism and hypothyroidism have reappeared. I want to know if hyperthyroidism and hypothyroidism are contagious.Doctor's answer:
Thyroid functional economic decline can lead to hypothyroidism, which is the full name of hypothyroidism. Hypothyroidism and hyperthyroidism are two diseases that will never occur simultaneously; they are a pair of diseases with exactly opposite functions. Whether it is hyperthyroidism or hypothyroidism, all thyroid diseases will never be infectious because they are not caused by viruses or bacteria, or autoimmune issues. Therefore, most of them are due to hereditary transmission across generations or poor lifestyle habits.
