Half of all people age 65 and older have arthritis. There are over 100 different forms of arthritis and many different symptoms and treatments. We do not know what causes most forms of arthritis. Some forms are better understood than others.
Arthritis causes pain and loss of movement. It can affect joints in any part of the body. Arthritis is usually chronic, meaning it can occur over a long period of time. The more serious forms can cause swelling, warmth, redness, and pain. The three most common kinds of arthritis in older people are osteoarthritis, rheumatoid arthritis, and gout.
Common Forms of Arthritis
Osteoarthritis, at one time called degenerative joint disease, is the most common type of arthritis in older people. Symptoms can range from stiffness and mild pain that comes and goes to severe joint pain and even disability.
Osteoarthritis usually affects the hands and the large weight-bearing joints of the body: the knees and hips. Early in the disease, pain occurs after activity and rest brings relief; later on, pain occurs with very little movement, even during rest.
Scientists think that several factors may cause osteoarthritis in different joints. Osteoarthritis in the hands or hips may run in families. Osteoarthritis in the knees is linked with being overweight. Injuries or overuse may cause osteoarthritis in joints such as knees, hips, or hands.
Rheumatoid arthritis can be one of the more disabling forms of arthritis. Signs of rheumatoid arthritis often include morning stiffness, swelling in three or more joints, swelling of the same joints on both sides of the body (both hands, for example), and bumps (or nodules) under the skin most commonly found near the elbow. Rheumatoid arthritis can occur at any age and affects women about three times more often than men.
Scientists don't know what causes Rheumatoid arthritis but think it has something to do with a breakdown in the immune system, the body's defense against disease. It is also likely that people who get rheumatoid arthritis have certain inherited traits (genes) that cause a disturbance in the immune system.
Gout occurs most often in older men. It affects the toes, ankles, elbows, wrists, and hands. An acute attack of gout is very painful. Swelling may cause the skin to pull tightly around the joint and make the area red or purple and very tender. Medicines can stop gout attacks, as well as prevent further attacks and damage to the joints.
Treatments for arthritis work to reduce pain and swelling, keep joints moving safely, and avoid further damage to joints. Treatments include medicines, special exercise, use of heat or cold, weight control, and surgery.
Medicines help relieve pain and reduce swelling. Acetaminophen should be the first drug used to control pain in patients with osteoarthritis. Patients with osteoarthritis who don't respond to acetaminophen and patients with rheumatoid arthritis and gout are most commonly treated with nonsteroidal anti-inflammatory drugs such as ibuprofen. People taking medicine for any form of arthritis should limit the amount of alcohol they drink.
Exercise, such as a daily walk or swim, helps keep joints moving, reduces pain, and strengthens muscles around the joints. Rest is also important for the joints affected by arthritis. Physical therapists can develop personal programs that balance exercise and rest.
Many people find that soaking in a warm bath, swimming in a heated pool, or applying heat or cold to the area around the joint helps reduce pain. Controlling or losing weight can reduce the stress on joints and can help avoid further damage.
When damage to the joints becomes disabling or when other treatments fail to reduce pain, your doctor may suggest surgery. Surgeons can repair or replace damaged joints with artificial ones. The most common operations are hip and knee replacements.
Arthritis symptoms may go away by themselves but then come back weeks, months, or years later. This may be why many people with arthritis try quack cures or remedies that have not been proven instead of getting medical help. Some of these remedies, such as snake venom, are harmful. Others, such as copper bracelets, are harmless but also useless. The safety of many quack cures is unknown.
Here are some tipoffs that a remedy may be unproven: claims that a treatment like a lotion or cream works for all types of arthritis and other diseases too; scientific support comes from only one research study; or the label has no directions for use or warnings about side effects.
Common Warning Signs of Arthritis
- Swelling in one or more joint(s)
- Morning stiffness lasting 30 minutes or longer )
- Joint pain or tenderness that is constant or that comes and goes )
- Not being able to move a joint in the normal way )
- Redness or warmth in a joint )
- Weight loss, fever, or weakness and joint pain that can't be explained
If any one of these symptoms lasts longer than 2 weeks, see your regular doctor or a doctor who specializes in arthritis (a rheumatologist). The doctor will ask questions about the history of your symptoms and do a physical exam. The doctor may take x-rays or do lab tests before developing a treatment plan.
