complete coverage on ARTHRITIS

Arthritis Causes

The causes of arthritis depend on the form of arthritis. Causes include injury (leading to degenerative arthritis), abnormal metabolism (such as gout and pseudogout), inheritance (such as in osteoarthritis), infections (such as in the arthritis of Lyme disease), and an overactive immune system (such as rheumatoid arthritis and systemic lupus erythematosus). Treatment programs, when possible, are often directed toward the precise cause of the arthritis.

More than 21 million Americans have osteoarthritis. Approximately 2.1 million Americans suffer from rheumatoid arthritis.

Arthritis Symptoms

Symptoms of arthritis include pain and limited function of joints. Inflammation of the joints from arthritis is characterized by joint stiffness, swelling, redness, and warmth. Tenderness of the inflamed joint can be present. Loss of range of motion and deformity can result. Certain forms of arthritis can also be associated with pain and inflammation of tendons surrounding joints.

Some forms of arthritis are more of an annoyance than a serious medical problem. However, millions of people suffer daily with pain and disability from arthritis or its complications. Moreover, many of the forms of arthritis, because they are rheumatic diseases, can cause symptoms affecting various organs of the body that do not directly involve the joints. Therefore, symptoms in some patients with certain forms of arthritis can also include fever, gland swelling, weight loss, fatigue, feeling unwell, and even symptoms from abnormalities of organs such as the lungs, heart, or kidneys.

When to Seek Medical Care

If joint pain, swelling, stiffness, redness, loss of motion or deformity occurs, medical evaluation by a health-care professional is warranted. Even minor joint symptoms that persist unexplained for over one week should be evaluated. For many forms of arthritis, it is essential that patients have an early evaluation as it is clear that this can both prevent damage and disability as well as make optimal treatment easier.
