What Is Arthritis?
Arthritis is a musculoskeletal condition that involves inflammation of one or more joints. It often leads to pain, stiffness, and swelling, which can make it hard to move or stay active. Types of arthritis include the following conditions:
- Osteoarthritis happens when the cartilage that cushions your joints breaks down over time, usually affecting people over 50.
- Rheumatoid arthritis is an autoimmune condition where the body mistakenly attacks its own joints, leading to inflammation and pain.
- Psoriatic arthritis is another autoimmune disorder affecting the large joints of the knees, shoulders, pelvis, and back that frequently affects people with psoriasis.
- Gout is a form of arthritis caused by the accumulation of uric acid crystals in the joints, leading to sudden and severe pain, swelling, and stiffness, often in the big toe.
These types of arthritis can affect joints in the knees, hands, fingers, elbows, back, and shoulders.
Common Causes of Arthritis
Arthritis can develop for several reasons, including the following:
- Cartilage wear: Over time, the cartilage in your joints can break down, leading to osteoarthritis.
- Autoimmune conditions: In rheumatoid arthritis, the immune system attacks the joints.
- Injury or overuse: Joint injuries or repetitive stress can increase the risk of arthritis.
Risk Factors and Who It Affects
Arthritis can affect anyone, but the following factors increase your risk:
- Age: The risk of arthritis increases as you get older.
- Gender: Women are more likely to develop rheumatoid arthritis, while men are more prone to gout.
- Family history: If arthritis runs in your family, you may be more likely to develop it.
- Lifestyle factors: Being overweight or having joint injuries can also increase your risk.
