Feeling worn out all the time is common. Many people blame "adrenal fatigue". This post explains what that term means, what doctors say about it, and what is worth doing if you are tired for weeks.
What is "adrenal fatigue"?
"Adrenal fatigue" is a name some people use for a group of symptoms said to come from long-term stress. The idea is that the adrenal glands, small glands above the kidneys that make the stress hormone cortisol, cannot keep up.
The Endocrine Society says there is no scientific proof that adrenal fatigue is a true medical condition. Mayo Clinic says it is not an official medical diagnosis. Adrenal insufficiency, where the adrenal glands do not make enough hormones, is a different and recognized condition that doctors diagnose with medical tests.
Symptoms that get blamed on it
Constant tiredness
Trouble falling asleep or waking up
Cravings for salty or sugary foods
Needing caffeine to get through the day
The Endocrine Society says these symptoms are common and not specific. They can come from many conditions, including adrenal insufficiency, depression and obstructive sleep apnea, and they can also be part of a normal, busy life.
Why it matters
If you accept "adrenal fatigue" as the answer, the real cause may be missed. The Endocrine Society also says the tests offered for it are not based on scientific facts, and it is concerned that supplements sold as adrenal fatigue treatments could be harmful.
One functional medicine clinic publishes a guide to adrenal fatigue treatments. The Endocrine Society says the reported treatment for adrenal fatigue is not approved by the U.S. Food and Drug Administration.
What to do if you are tired for weeks
See a doctor. Ask about possible causes, such as sleep, mood and other health problems, and which tests, if any, are useful.
Look at the basics. The Endocrine Society says regular sleep and wake times, healthy food and exercise will almost always help you feel better, whatever the diagnosis.
Talk to your doctor before taking any supplement or herb.
When to get help sooner
Mayo Clinic lists lightheadedness, weight loss, nausea and vomiting, and feeling very tired among the symptoms of adrenal insufficiency. If you have these, see a doctor rather than treating yourself.
