Globally, arthritis affects a significant portion of the population, impacting quality of life and leading to physical disability. Around 1.71 billion people live with musculoskeletal conditions, which include various forms of arthritis. Osteoarthritis alone affects 15% of the global population over the age of 30, with nearly 600 million cases as of 2020. This number is projected to reach nearly 1 billion by 2050 due to aging, population growth, and rising obesity rates. But what actually is arthritis? Arthritis is a broad term used to describe inflammation in the joints, leading to pain, swelling, stiffness, and reduced mobility. It has various causes depending on the type of arthritis, with the most common forms being osteoarthritis (OA) and rheumatoid arthritis (RA). Here’s an overview:
1. Osteoarthritis (OA)
• Cause:
OA is primarily caused by wear-and-tear damage to the cartilage, the tissue that cushions joints. Over time, this leads to bone-on-bone contact, causing pain and inflammation.
• Risk Factors:
• Aging
• Joint overuse or injury
• Obesity (increases stress on weight-bearing joints)
• Genetics
• Poor joint alignment or structural abnormalities
2. Rheumatoid Arthritis (RA)
• Cause:
RA is an autoimmune condition where the immune system mistakenly attacks the synovium (lining of the joints), leading to inflammation and joint damage.
• Risk Factors:
• Genetics (HLA-DR4 gene association)
• Environmental triggers (e.g., smoking or infections)
• Hormonal factors (more common in women)
3. Gout
• Cause:
Gout occurs due to the buildup of uric acid crystals in the joints, often triggered by high levels of uric acid in the blood (hyperuricemia).
• Risk Factors:
• Diet high in purines (e.g., red meat, alcohol)
• Obesity
• Genetics
• Certain medications (e.g., diuretics)
4. Psoriatic Arthritis
• Cause:
This is another autoimmune disease linked to psoriasis, where the immune system attacks healthy joint tissue.
• Risk Factors:
• Genetic predisposition
• History of psoriasis
• Environmental factors
5. Other Causes
• Infections: Septic arthritis occurs when a bacterial, viral, or fungal infection invades the joint.
• Autoimmune Disorders: Conditions like lupus or ankylosing spondylitis can lead to arthritis symptoms.
• Trauma: Injuries can lead to post-traumatic arthritis later in life.
• Metabolic Disorders: Conditions like hemophilia or hemochromatosis can also contribute to joint damage and arthritis.
Prevention and Management
While some causes (like genetics) cannot be controlled, steps to reduce risk and manage arthritis include:
• Maintaining a healthy weight
• Staying physically active
• Avoiding joint injuries
• Managing chronic conditions like diabetes or gout
• Eating an anti-inflammatory diet
