Just Tired or a Medical Problem?

Fatigue is a common complaint. Research shows about 38 percent of Americans are poorly rested at least four days of the week, and according to the Centers for Disease Control and Prevention, 15 percent of women and 10 percent of men report being "very tired or exhausted" most days or every day.

Although fatigue can indicate a serious medical problem, for most people who are otherwise healthy, the issue is simple: not getting enough sleep. More than a third of people in the United States do not get at least seven hours of sleep per night—and some studies show that number is even higher.

If steps to get more sleep do not help, talk to your health care provider—especially if you experience other symptoms. Medical conditions like heart disease, sleep apnea, anemia, chronic fatigue syndrome, diabetes, depression, and thyroid disorders all can cause fatigue.
