Gout is a common and complex form of arthritis that can affect anyone. It's characterized by sudden, severe attacks of pain, swelling, redness, and tenderness in the joints, often the joint at the base of the big toe.

Gout occurs when urate crystals accumulate in your joint, causing the inflammation and intense pain of a gout attack. Urate crystals can form when you have high levels of uric acid in your blood.

Your body produces uric acid when it breaks down purines — substances that are found naturally in your body, as well as in certain foods. Managing your intake of high-purine foods can help control uric acid levels.
