Types of Arthritis

Comparing 3 Common Arthritic Conditions

Page 1 of 3
When you hear the term "arthritis," you probably imagine painful and stiff joints. While that is pretty accurate (arthritis literally means "joint inflammation"), there are actually over 100 different types of arthritis, which is the leading cause of disability in the United States. For most people, arthritis is unavoidable since the joints naturally degenerate over time. Most people over 50 years of age show some symptoms of arthritis. In general, arthritis can affect the joints, muscles, skin and internal organs, and there is no known cure for this chronic disease.

Here's a basic overview of the three most common types of arthritis.

Osteoarthritis, the most common form of arthritis, affects an estimated 21 million adults in the United States alone. Osteoarthritis begins with the breakdown of joint cartilage which results in pain, stiffness, swelling and tenderness. The joints of the fingers, spine, hips and knees, are most often affected, but osteoarthritis can also affect the shoulders, elbows, wrists and ankles.
  • Who's at risk for osteoarthritis? Age is another leading risk factor, because osteoarthritis usually occurs as people get older. Other factors that seem to contribute to osteoarthritis include genetics, joint damage (resulting from injury or repetitive movement) and obesity.
  • Can osteoarthritis be prevented? There's no fool-proof way to prevent this condition. But certain risk factors that are associated with the development of osteoarthritis (such as obesity and physical inactivity) are within your control. By maintaining a healthy body weight, getting regular exercise, building strong bones through a healthy diet, and trying to prevent joint injuries, you may be able to reduce your risk.
  • What are the symptoms of osteoarthritis? Common symptoms include: joint pain and swelling (especially after activity), limited flexibility, a grinding sensation when a joint moves, numbness or tingling, and deep aching in the joints. As osteoarthritis worsens, the pain and discomfort worsens and becomes constant, possibly interfering with sleep.
  • How is osteoarthritis treated? If you experience joint pain, stiffness and/or swelling for more than two weeks, make an appointment to see your doctor, as early diagnosis can help minimize the pain and disability of osteoarthritis. The two of you can develop a plan that includes a combination of diet and exercise changes, weight loss, physical therapy, and over-the-counter or prescription medication. Continued ›

  • I recall banging my elbow at work about 7 years ago and being told by my GP who is generally quite good that I now had arthritis in it . Which ended up just bringing out mu Bullheadedness. It obviously couldn't have been arthritis or my saying to myself "screw you (albeit in a less polite form ) worked miracles as it doesn't bother me at all now. - 7/17/2015 10:49:23 PM
  • I've already had both knees operated on, am having physical therapy for an irritated tendon in my hand, and have fibromyalgia and osteopenia. It's almost impossible to wear without warm-water therapy, i.e., water aerobics in a heated pool. Massage helps and cuddling under a heated blanket. It's really important to keep moving! - 5/26/2012 1:40:51 PM
  • @HelenLocklear How can you tell the difference? - 8/14/2010 9:27:21 PM
  • While I can certainly agree that Fibromyalgia is debilitating (as I have it) it isn't really like the other types of arthritis in that it isn't degenerative.

    Just learning about all this myself. I had both hips replaced in October of 08 and it was entirely necessary. I had no cartilage left on either hip joint. Only got the diagnosis of OA 4 months previous to that.

    Fun and games. - 12/28/2009 8:52:27 PM

  • Your article was very interesting and you had good information. I have the kind that affects my knees. i have worn out the cartilege in both of my knees. So I will need surgery to rebuild my knees, which I hope to get soon.Keep up the good work - 10/29/2008 2:20:55 PM
  • nice article somewhat interesting but could use more detail - 5/21/2008 12:11:23 PM
    The article was well presented .
    It was good to see that Fibromyalgia was included.
    It is such a debilitating disease..

  • there is one arthritis type missing from your article. It's the one I have which is arthritis due to having pysorisis ( skin condition). It would be helpful to have information about that. - 2/3/2008 1:28:47 PM
