Just as the tread on your tires wears away over time, the cartilage that cushions your joints can break down, too. It's a condition called osteoarthritis. And without enough padding, your bones will hurt when they rub against each other.
Frayed cartilage can't heal or grow back. "There's no way to reverse the arthritis once it has started," says Michaela M. Schneiderbauer, MD, an orthopedic surgeon at the University of Miami Miller School of Medicine. But you can ease the pain and protect the cartilage you still have. Use these tips to slow the damage.
1. Slim down if you're overweight. It will help take stress off your knees and hips. Every pound you lose removes 4 pounds of pressure off your knee. That lessens wear and tear in the joint, Schneiderbauer says. "You may actually slow the progress of arthritis if you lose a significant amount of weight."
What's "significant"? "Every 10 pounds you lose will reduce pain by 20%," says Charles Bush-Joseph, MD, of Rush University Medical Center.
2. Do aerobic exercise. Arthritis pain may make you reluctant to work out, but research shows that pain and stiffness get worse when you aren't active enough. Regular exercise that gets your heart pumping will boost your blood flow, which keeps cartilage well nourished. And an extra benefit: it helps you reach a healthy weight.
"Stay as active as you can tolerate," Schneiderbauer says. "But avoid high-impact activities, like jumping and running." Better choices are things like walking, cycling, and swimming. Aim for 30 minutes of aerobic exercise at least 5 days a week.
3. Build stronger muscles around your joints. It can help your body absorb some of the shock that normally goes through your joint when you move around during the day.
"A strong muscle will prevent a limb from slapping down on the pavement and jarring the joint," Bush-Joseph says.
Try to build up the muscles that surround your joint. To improve symptoms in your knee, for example, strengthen the quadriceps muscles, which are in the front of your thigh. A physical therapist or personal trainer with experience in working with people with arthritis can show you exercises that will help.
