Fatigue

Fatigue is a common symptom. It is often quite debilitating.

Fatigue  has many different causes. Unfortunately physicians often do not diagnose the root cause of fatigue.

They often write it off by saying, things like "It's all in your head", "You must be depressed", "Oh, you have Chronic Fatigue Syndrome", or "You're just getting older."

It takes an experienced endocrinologist to sort out the various causes of fatigue.

The common causes of fatigue include:

Under-active thyroid

Over-active thyroid
