Hypothyroidism

In this part we focus on hypothyroidism, which is typically caused by an underactive thyroid, and comprises the vast majority of thyroid disease cases. We explore potential causes for the disease, describe its symptoms, and discuss other diseases that have similar symptoms in case you have one of them instead of—or in addition to—a thyroid problem.

Chapter 7 explains the key thyroid blood tests you need, and details how to obtain and analyze your lab results. Chapter 8 tells you about your medication options, and why what most doctors automatically prescribe may not be the best choice. And Chapter 9 guides you through the process of determining your perfect dosage for optimal health.
