Patient's question:
I want to know what causes hypothyroidism. My older brother has this problem, but I don't see that his daily habits are that bad.Doctor's answer:
According to the situation you currently described, there are many reasons that can lead to hypothyroidism, but the most common factor to consider is autoimmune factors. Second, it should be considered that thyroid inflammation can cause hypothyroidism. Additionally, it could be due to radioactive reasons that lead to hypothyroidism, and it is not ruled out that drug factors can also cause it.
