Types of Arthritis
There are many different types of arthritis, each with unique causes and characteristics. Some of the most common types of arthritis include:
Degenerative Arthritis
The most common form of arthritis is osteoarthritis.3 This condition occurs when the cartilage that cushions the ends of bones wears away, causing bone-on-bone contact. This friction leads to pain, swelling, and stiffness. Severe cases may significantly impact quality of life, sometimes necessitating joint replacement surgery. Preventative measures include maintaining a healthy weight, staying active, and avoiding injuries.
Inflammatory Arthritis
Inflammatory arthritis arises when the immune system mistakenly attacks the joints, causing inflammation. This can lead to joint erosion and damage to internal organs, eyes, and other parts of the body. Rheumatoid arthritis and psoriatic arthritis are common examples. Early diagnosis and aggressive treatment are crucial for managing these conditions.
Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints. Unlike osteoarthritis, which is caused by wear and tear, RA is an autoimmune disease where the immune system attacks the synovium—the lining of the membranes that surround the joints. This results in inflammation that can eventually lead to damaged joints and deformity.
Infectious Arthritis
Infectious arthritis occurs when a virus, bacterium, or fungus infects a joint, leading to inflammation. This type of arthritis can often be treated with antibiotics, but severe cases may require additional interventions. Common culprits include organisms like Shigella, Salmonella, Chlamydia, Gonorrhea, and Hepatitis C.
Metabolic Arthritis
This type of arthritis, also known as gout, occurs when the body produces an excess of uric acid, a byproduct of purine breakdown. When uric acid builds up, it can form sharp, crystalline needles in the joints, causing intense pain or gout attacks. Without proper management, gout can become chronic and debilitating.
