Mobility — the ability to move purposefully around your environment — is vitally important to health and well-being.

Nearly one-third to one-half of adults ages 65 and older experience impaired mobility. At first, it may not seem like a big deal — many people with impaired mobility learn to just move a little more slowly and a little more deliberately. Some people work around the problem by relying on a cane or walker.

That’s why it’s important to intervene to either prevent future mobility impairments or reduce existing ones.But taking impaired mobility “lying down” can cause your health to spiral downward. As you move less, pounds may start to creep on. You might withdraw from social relationships and activities that challenge you mentally. Exercise may become difficult, and lack of activity can worsen many health problems. This cycle of physical, emotional, and mental decline further restricts mobility.

For most people, the ability to rely on their own bodies, skills, and mental agility is a crucial part of living a satisfying life. Having full mobility helps you fully engage with the world and fosters a sense of self-sufficiency that can help you live independently well into your later years.

Medications make a difference — generally a positive one — in the lives of many people. Insulin keeps blood sugar under control, cholesterol-lowering drugs can reduce the chances of having a heart attack, and thyroid medication can restore a normal hormone level. These are but a few examples.

At the same time, all drugs carry side effects, and can interact with other medications. For many medications, one or more side effects affect balance. And that can increase your chances of taking a fall. How? According to the Centers for Disease Control and Prevention, common problems include vision changes, dizziness or lightheadedness, drowsiness, and impaired alertness or judgment. Some medications may damage the inner ear, spurring temporary or permanent balance disorders.

How do I know if this is a problem for me?

Some of the commonly prescribed medications that can affect balance include:

• antidepressants
• anti-anxiety drugs
• antihistamines prescribed to relieve allergy symptoms
• blood pressure and other heart medications
• pain relievers, both prescription and nonprescription
• sleep aids (over-the-counter and prescription forms)

Sometimes the problem isn’t a single drug but the combination of medications being taken together. Older adults are especially vulnerable, because drugs are absorbed and broken down differently as people age.

If you are concerned about how your medications may be affecting your balance, call you doctor and ask to review the drugs you’re taking, the dose, and when you take them. It is never a good idea to just stop taking a medication without consulting your health care provider first. Doing so can create even more health risks.

Even the healthiest people can find it hard to stick with an exercise regimen — and if you suffer from the joint pain of arthritis, moving your body may be the last thing you want to think about. But regular exercise not only helps maintain joint function, but also relieves stiffness and reduces pain and fatigue.

If you have arthritis, you want to be sure your exercise routine has these goals in mind:

1. A better range of motion (improved joint mobility and flexibility). To increase your range of motion, move a joint as far as it can go and then try to push a little farther. These exercises can be done any time, even when your joints are painful or swollen, as long as you do them gently.
2. Stronger muscles (through resistance training). Fancy equipment isn’t needed. You can use your own body weight as resistance to build muscles. For example, the simple exercise described below can help ease the strain on your knees by strengthening your thigh muscles. Sit in a chair. Now lean forward and stand by pushing up with your thigh muscles (use your arms for balance only). Stand a moment, then sit back down, using your thigh muscles.
3. Better endurance. Aerobic exercise — such as walking, swimming, and bicycling — strengthens your heart and lungs and thereby increases endurance and overall health. Stick to activities that don’t jar your joints, and avoid high impact activities such as jogging. If you’re having a flare-up of symptoms, wait until it subsides before doing endurance exercise.
4. Better balance. There are simple ways to work on balance. For example, stand with your weight on both feet. Then try lifting one foot while you balance on the other foot for 5 seconds. Repeat on the other side. Over time, work your way up to 30 seconds. Yoga and tai chi are also good for balance.

Arthritis doesn’t have to keep you from enjoying life.
