Feeling tired? Don't just chalk it up to age
"I'm tired, doctor. It's hard to get up and about. I've been feeling kind of down, but I know I'm getting old and I just have to live with it."
This fatalistic stance relies on widely held but mistaken assumptions about what constitutes normal aging. In fact, fatigue, weakness and depression aren't to-be-expected consequences of growing older, said Callahan, director of the Center for Aging Research at Indiana University's School of Medicine.
"People have a perception . . . that aging equals decline," said Jeanne Wei, a geriatrician who directs the Donald W. Reynolds Institute on Aging at the University of Arkansas for Medical Sciences. "That's just wrong."
Of course, peoples' bodies do change as they get on in years. But this is a gradual process. If you suddenly find your thinking is cloudy and your memory unreliable, if you're overcome by dizziness and your balance is out of whack, if you find yourself tossing and turning at night and running urgently to the bathroom, don't chalk it up to normal aging.
Go see your physician. The earlier you identify and deal with these problems, the better.
Here are four common concerns that should spark attention — only a partial list of issues that can arise:
- Fatigue. You have no energy. You're tired all the time.
Don't underestimate the impact: Chronically weary older adults are at risk of losing their independence and becoming socially isolated.
Nearly one-third of people age 51 and older experience fatigue, according to a 2010 study in the Journal of the American Geriatrics Society. (Other estimates are lower.) There are plenty of potential culprits: Sleep problems, pain, gastrointestinal reflux and medications for blood pressure can induce fatigue, as can infections, arthritis and other conditions, an underactive thyroid, poor nutrition and alcohol use.
All can be addressed, doctors say. Perhaps most important is ensuring that older adults remain physically active and don't become sedentary.
"If someone comes into my office walking at a snail's pace and tells me, 'I'm old; I'm just slowing down,' I'm, like, 'No, that isn't right,' " said Lee Ann Lindquist, a professor of geriatrics at Northwestern University's Feinberg School of Medicine in Chicago.
- Appetite loss. You don't feel like eating, and you've been losing weight.
This puts you at risk of developing nutritional deficiencies and frailty, and it raises the prospect of an earlier-than-expected death. Between 15 and 30 percent of older adults are believed to have what's known as the "anorexia of aging."
Physical changes associated with aging — notably declines in vision, taste and smell, all of which make food attractive — can contribute. So can other conditions: decreased saliva production (a medication-induced problem that affects about one-third of older adults); constipation (affecting up to 40 percent of seniors); depression; social isolation (people don't like to eat alone); dental problems; illnesses and infections; and medications (which can cause nausea and reduced taste and smell).
If you had a pretty good appetite before and that has now changed, pay attention, said Lucy Guerra, director of general internal medicine at the University of South Florida in Tampa. Treating dental problems and other conditions, adding spices to food, adjusting medications and sharing meals with others can all make eating a more enjoyable and healthy experience.
- Depression. You're sad, apathetic and irritable for weeks or months at a time.
Depression in later life can have profound consequences, compounding the effects of chronic illnesses such as heart disease, leading to disability, affecting cognition and, in extreme cases, resulting in suicide.
Half a century ago, it was believed that "melancholia" was common in later life and that seniors naturally withdrew from the world as they realized that their days were limited, Callahan explained. Since then, researchers have shown that older adults tend to be happier than people in other age groups: Only 15 percent have major depression or minor variants.
Late-life depression is typically associated with a serious illness such as diabetes, cancer, arthritis or stroke; deteriorating hearing or vision; and life changes such as retirement or the loss of a spouse. While grief is normal, persistent sadness that is accompanied by apathy, withdrawal from social activities, disturbed sleep and self-neglect is not, Callahan said.
With treatments such as cognitive behavioral therapy and antidepressants, 50 to 80 percent of seniors can expect to recover.
- Weakness. You can't rise easily from a chair, screw the top off a jar or lift a can from the pantry shelf. You may have sarcopenia — a notable loss of muscle mass and strength that affects about 10 percent of adults older than 60. If untreated, sarcopenia will affect your balance, mobility and stamina, and raise the risk of falling, becoming frail and losing independence.
Age-related muscle atrophy, which begins when people reach their 40s and accelerates when they're in their 70s, is part of the problem. Muscle strength declines even more rapidly — slipping about 15 percent per decade starting around age 50.
The solution: exercise, including resistance and strength training exercises, and good nutrition, including getting adequate amounts of protein.
Other causes of weakness can include inflammation, hormonal changes, infections and problems with the nervous system.
Watch for sudden changes. "If you're not as strong as you were yesterday, that's not right," Wei said. Also, watch for weakness on only one side, especially if it's accompanied by speech or vision changes. That could be a sign of a stroke, which would require immediate medical attention.
Taking steps to address weakness doesn't mean you'll have the same strength and endurance as when you were in your 20s or 30s. But it may mean that doctors catch a serious or preventable problem early and forestall further decline.
