Surgery is a high-risk treatment for thyroid diseases, and hyperthyroidism with nodules is even more different from ordinary thyroid diseases. Improper surgery or negligence can easily lead to hyperthyroidism crisis (high mortality rate, which should be avoided as far as possible in medicine). For this reason, many hospitals refused to perform surgery for Wang. What are the dangers of hyperthyroidism with thyroid nodules?
