Arthritis – Osteoarthritis
Osteoarthritis (OA) is the most common form of arthritis and a common cause of disability among older people. Almost 27 million American adults have it. Age is one of the biggest risk factors. Women have higher rates of OA, especially after age 50.
Arthritis is a general term used to refer to any disorder that affects the joints. Joints are places where bones meet, such as your elbow or knee. There are more than 100 types of arthritis. Most types of arthritis cause pain or swelling in the joints. Some types also can cause problems in your organs, such as your eyes or skin.
The most common type, osteoarthritis (OSS-tee-oh-ar-THREYE-tuhss), is often related to aging or injury. In osteoarthritis, the slippery tissue that covers the ends of bones in the joint breaks down. When this happens, the bones grind against each other. This causes pain and swelling. It most often affects the fingers, knees, and hips.
Rheumatoid (ROO-muh-toid) arthritis is an autoimmune disease, in which the body's defense system, called the immune system, attacks the lining of the joints throughout the body. Often these are joints in the hands and feet. Rheumatoid arthritis also may affect internal organs.
Gout is a common and painful type of arthritis caused by a buildup of uric acid in the body. Deposits of uric acid in joints — often the big toe — cause extreme pain, swelling, and redness. Other joints may be affected as well.
If you have joint pain, see your doctor. Finding out about arthritis early and getting the right treatment can prevent further joint damage and help control symptoms. Many types of treatment are available, including medicines and surgery.
These steps also might help ease arthritis symptoms:
- Maintain a healthy weight. Being overweight can strain your knees and hips.
- Be physically active. Moving all of your joints will help you. Your doctor or nurse can show you some gentle stretching exercises and how to move more easily. Going for a walk every day will help, too.
- Take a warm shower in the morning.
- Use an ice pack on sore areas.
Arthritis can make it hard to work and do activities you enjoy. Even if only one joint is affected, you might need to change the way you do many daily activities to use this joint less. Your doctor and therapists can help you find new ways of doing things in your home or workplace, so you can live with less pain.
