Do rheumatoid arthritis (RA) and gout have the same cause?

ANSWER

No. Rheumatoid arthritis (RA) and gout don’t have the same cause. While they’re both types of arthritis, their underlying causes are completely different. RA is an autoimmune condition. It happens when your body’s immune system attacks the tissue that lines your joints. This attack causes painful swelling, inflammation, and joint deformity. Since RA is an immune system disease (your doctor will call it an autoimmune condition), it can affect other parts of the body, too, including the skin, eyes, and heart.

Gout affects people with too much uric acid in their blood. Your body creates this type of acid when it breaks down certain foods, including meat and seafood. Your kidneys normally get rid of it when you pee. But when there’s too much of it in your system, uric acid can form needle-like crystals. These crystals build up in joints and surrounding tissue where they cause pain and inflammation.
