What do you do as a teenager when you go from being an active A-student with a busy social life to suddenly feeling as if you have no energy left? What's happened? Why do you feel so tired all of the time? And why is it so difficult to pinpoint what's wrong and get the right treatment? In Tired Teens, Dr. Fischer offers answers, hope and healing. He draws on his years of experience treating thousands of young patients at Mayo Clinic to transfer hard-earned knowledge in a clear and compassionate way to his readers. If you're a teenager bothered by persistent tiredness - or a parent of one - then this book is for you.
