What the Yuck: I'm tired all the time

Q: I keep reading about a problem called “adrenal fatigue.” How can I tell if I have it or if it's something else?

Well, there’s some debate as to whether this even exists. There is a condition called adrenal insufficiency, or Addison’s disease, in which your adrenal glands don’t produce enough hormones, and you’re left feeling extremely fatigued - even light-headed and achy. A blood test can diagnose this.

Adrenal fatigue, on the other hand, is a catchall term used to describe a milder form of insufficiency that can’t be detected by blood tests.

The symptoms linked to it include aches, nervousness, and sleep and digestive problems, in addition to fatigue. But it isn’t a recognized medical diagnosis, and for good reason: There’s no scientific proof that slightly low levels of the hormones produced by your adrenal glands, such as cortisol, cause these symptoms.

If you feel inexplicably tired, see your doctor to find out if it’s a sign of a real health issue, such as a thyroid problem or depression.
