6 Reasons You're Tired All The Time

Prevention Logo By Julie Evans of Prevention | Slide 1 of 6: These aren’t your average chocolate chip cookies. They’re dense, fudgy, and—wait for it—good for you, says Dixya from Food Pleasure and Health. Using mashed ripe banana makes the cookies moist and sweet without the need for butter or sugar. And the batter actually has more quinoa in it than all-purpose flour, so it serves up a fair share of fiber, too. (Sneak more fiber into your diet with these helpful tips.)

1. Anemia

The fatigue caused by anemia is the result of a lack of red blood cells, which bring oxygen from your lungs to your tissues and cells. You may feel weak and short of breath. Anemia may be caused by an iron or vitamin deficiency, blood loss, internal bleeding, or a chronic disease such as rheumatoid arthritis, cancer, or kidney failure. Women of childbearing age are especially susceptible to iron-deficiency anemia because of blood loss during menstruation and the body's need for extra iron during pregnancy and breastfeeding, explains Laurence Corash, MD, adjunct professor of laboratory medicine at the University of California, San Francisco.

The symptoms: Feeling tired all the time is a major one. Others include extreme weakness, difficulty sleeping, lack of concentration, rapid heartbeat, chest pains, and headache. Simple exercise, such as climbing the stairs or walking short distances, can cause fatigue.

The tests: A thorough evaluation for anemia includes a physical exam and blood tests, including a complete blood count (CBC), to check the levels of your red blood cells. It's also standard to check the stool for blood loss.
