Clinical Information
  • A condition marked by increased levels of uric acid in the blood, joints, and tissue. The buildup of uric acid in the joints and tissues causes arthritis and inflammation.
  • Gout is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints. Gout occurs when uric acid builds up in your blood. This happens if your body produces extra acid or does not eliminate enough, or if you eat too many foods with purines, such as liver and dried beans. Pseudogout has similar symptoms and is sometimes confused with gout. However, it is caused by calcium phosphate, not uric acid.often, gout first attacks your big toe. It can also attack ankles, heels, knees, wrists, fingers and elbows. You are more likely to get gout if you
    • are a man
    • have family member with gout
    • drink alcohol
    at first, gout attacks usually get better in days. Eventually, attacks last longer and occur more often. Uric acid buildup can lead to kidney stones. Untreated gout can cause permanent joint and kidney damage. You can treat gout with medicines. nih: national institute of arthritis and musculoskeletal and skin diseases
  • Hereditary metabolic disorder characterized by recurrent acute arthritis, hyperuricemia and deposition of sodium urate in and around the joints, sometimes with formation of uric acid calculi.
