What Is Arthritis?

Arthritis is more than just wear and tear or an old person’s disease.

Arthritis is very common but is not well understood. Actually, “arthritis” is not a single disease; it is an informal way of referring to joint pain or joint disease. There are more than 100 types of arthritis and related conditions. People of all ages, sexes, and races can and do have arthritis, and it is the leading cause of disability. More than 50 million adults and 300,000 children have some type of arthritis. It is most common among women and occurs more frequently as people get older.

Common arthritis joint symptoms include swelling, pain, stiffness, and decreased range of motion. Symptoms may come and go. They can be mild, moderate, or severe. They may stay about the same for years but can progress or get worse over time. Severe arthritis can result in chronic pain, inability to do daily activities, and make it difficult to walk or climb stairs. 

Arthritis can cause permanent joint changes. These changes may be visible, such as knobby finger joints, but often the damage can only be seen on X-ray. Some types of arthritis also affect the heart, eyes, lungs, kidneys and skin as well as the joints.

Types of Arthritis

1.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 (i.e., an anterior cruciate ligament, or ACL tear). 

Regular physical activity, hot and cold therapies, over-the-counter pain relievers and assistive devices are commonly used to help manage mild to moderate osteoarthritis symptoms. If joint symptoms are severe, causing limited mobility and affecting the quality of life, joint replacement may be necessary. Osteoarthritis may be prevented by staying active, maintaining a healthy weight and avoiding injury and repetitive movements. 

2.Inflammatory Arthritis

A healthy immune system is protective. It generates internal inflammation to get rid of infection and prevent disease. But with inflammatory types of arthritis, the immune system doesn’t work properly and mistakenly attacks the joints with uncontrolled inflammation, potentially causing joint erosion. Inflammation can also damage to internal organs, eyes and other parts of the body. Rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis and gout are examples of inflammatory arthritis. 

Researchers believe that a combination of genetics and environmental factors can trigger autoimmunity. Smoking is an example of an environmental risk factor that can trigger rheumatoid arthritis in people with certain genes.

With autoimmune and inflammatory types of arthritis, early diagnosis and aggressive treatment is critical. Slowing disease activity can help minimize or even prevent permanent joint damage. Remission (little to no disease activity) is the goal and may be achieved by using one or more medications known as disease-modifying antirheumatic drugs (DMARDs). Other treatment goals include reducing pain, improving function and preventing further joint damage.

3.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). In many cases, timely treatment with antibiotics may clear the joint infection, but sometimes the arthritis becomes chronic.

4.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 it quickly enough. In some people, uric acid builds up and forms needle-like crystals in the joint, resulting in sudden spikes of extreme joint pain, or a gout attack. Gout can come and go in episodes or, if uric acid levels aren’t reduced, can become chronic, causing ongoing pain and disability.

5.Juvenile Arthritis (JA)

Juvenile arthritis (JA), also known as pediatric rheumatic disease, isn’t a specific disease. It’s an umbrella term to describe the inflammatory and rheumatic diseases that develop in children under the age of 16. These conditions affect nearly 300,000 kids and teens in the United States.

Most kinds of JA are autoimmune or autoinflammatory diseases. That means the immune system, which is supposed to fight against foreign invaders like viruses and germs, gets confused and releases inflammatory chemicals that attack healthy cells and tissue. In most JA cases this causes joint inflammation, swelling, pain and tenderness, but some types of JA have few or no joint symptoms or only affect the skin and internal organs. 

What You Can Do

The most important first step is to get an accurate diagnosis of what’s causing your joint pain.  Talk to our experienced doctor about your symptoms.  You may require investigation in the form of blood work and imaging and be referred to a rheumatologist or orthopedic doctor who specializes in arthritis and related conditions. There are many things that can be done to preserve joint function, mobility and quality of life. Learning about the disease and treatment options, making time for physical activity and maintaining a healthy weight are essential.

Contact our doctors if you are suffering from arthritis for the best possible management.
