What is gout? Gout is a common type of inflammatory arthritis . It causes pain, swelling, and redness in one or more joints. It usually happens as a flare, which can last for a week or two and then gets better. The flares often begin in your big toe or a lower limb. What causes gout? Gout happens when too much uric acid (urate) builds up in your body over a long time. Uric acid is a waste product your body makes when it breaks down purines. Purines are substances that are in your body's tissues and in many foods. When your body breaks down old cells or digests foods that contain purine, most of the uric acid that's made dissolves in your blood. Your kidneys filter the uric acid out of your blood, and it leaves your body in your urine (pee). However, sometimes your body can make too much uric acid or does not remove enough of it. Then the uric acid levels build up in your body, including in your blood. Having too much uric acid in the blood is called hyperuricemia. It does not cause health problems for everyone. But in some people, uric acid forms needle-like crystals. They can form in your joints, which causes gout. The crystals can also cause kidney stones . Calcium pyrophosphate arthritis, sometimes called pseudogout, is a related disease. It causes similar symptoms and is sometimes confused with gout. But it is caused by a buildup of calcium phosphate, not uric acid. Who is more likely to develop gout? Many people develop gout. You are more likely to get it if you: Are male.
