Types of Arthritis

Arthritis refers to a group of conditions characterized by inflammation and pain in the joints. There are many different types of arthritis, each with its own causes, symptoms, and treatment approaches. Here are some of the most common types:

  1. Osteoarthritis (OA): This is the most common form of arthritis, primarily affecting older adults. It occurs when the protective cartilage that cushions the ends of bones wears down over time, leading to joint pain, stiffness, and reduced mobility.
  2. Rheumatoid Arthritis (RA): RA is an autoimmune disease where the body’s immune system mistakenly attacks the joints, leading to inflammation and joint damage. It commonly affects the hands, wrists, and feet and can cause swelling, stiffness, fatigue, and systemic symptoms.
  3. Psoriatic Arthritis (PsA): PsA is a type of arthritis that affects individuals with psoriasis, a chronic skin condition. It causes joint pain, stiffness, and swelling, often in combination with skin lesions. PsA can affect any joint and may also cause nail changes.
  4. Gout: Gout is a type of arthritis characterized by sudden and severe attacks of joint pain, often in the big toe. It occurs due to the buildup of uric acid crystals in the joints. Gout attacks can be triggered by certain foods, alcohol, or medications.
  5. Juvenile Arthritis: Juvenile arthritis refers to a group of arthritic conditions that develop in children and teenagers. The symptoms are similar to adult forms of arthritis and can affect one or multiple joints. Juvenile arthritis can cause growth problems and may have long-term effects on the child’s development.
  6. Ankylosing Spondylitis (AS): AS primarily affects the spine and sacroiliac joints, causing inflammation and stiffness. Over time, it can lead to fusion of the spine, resulting in a loss of flexibility and posture changes.
  7. Reactive Arthritis: Reactive arthritis typically develops after an infection, such as a gastrointestinal or genitourinary infection. It causes joint inflammation, often affecting the joints of the knees, ankles, and feet. Other symptoms may include eye inflammation and urinary tract problems.
  8. Systemic Lupus Erythematosus (SLE): While primarily a systemic autoimmune disease, SLE can also involve joint inflammation, leading to a form of arthritis. It affects multiple organs and systems in the body and can cause joint pain, swelling, fatigue, and other systemic symptoms.
