I am having the right side of my thyroid and isthmus taken out tomorrow, what should i expect?

Discuss w/doctor: These kind of questions need to be discussed with the doctor who is going to be performing the surgery. He/she can give you a much better and more specific idea of what to expect. You can find information about surgery from the internet, but not about your specific case. You will need brand name T4 replacement after surgery, and for the rest of your life.
