Types of arthritis:
Degenerative Arthritis: Osteoarthritis is the most common type of arthritis. When the cartilage – the slick, cushioning surface on the ends of bones – wears away, bone rubs against bone, causing pain, swelling and stiffness. Over time, joints can lose strength and pain may become chronic. Risk factors include excess weight, family history, age and previous injury (an anterior cruciate ligament, or ACL, tears, for example).
Inflammatory arthritis: is a term used to describe a group of conditions which affect your immune system. This means that your body’s defense system starts attacking your own tissues instead of germs, viruses and other foreign substances, which can cause pain, stiffness and joint damage. They’re also known as AUTOIMMUNE DISEASES. The most common forms of inflammatory arthritis are: rheumatoid arthritis / ankylosing spondylitis / psoriatic / arthritis / lupus.
These conditions are also called systemic diseases because they can affect your whole body. They can happen at any age.
Infectious Arthritis: A bacterium, virus or fungus can enter the joint and trigger inflammation. Examples of organisms that can infect joints are salmonella and Shigella (food poisoning or contamination), chlamydia and gonorrhea (sexually transmitted diseases) and hepatitis C (a blood-to-blood infection, often through shared needles or transfusions).
Metabolic Arthritis: Uric acid is formed as the body breaks down purines, a substance found in human cells and in many foods. Some people have high levels of uric acid because they naturally produce more than is needed or the body can’t get rid of the uric acid quickly enough. In some people the uric acid builds up and forms needle-like crystals in the joint, resulting in sudden spikes in extreme joint pain, or a gout attack.
