What causes gout?

Speed

Simple Answer

Gout happens when too much uric acid builds up in the body over time. Uric acid is made when the body breaks down purines, which are found in body tissues and many foods. If the body makes too much uric acid or does not remove enough of it, crystals can form in the joints and cause gout.

What It Means

This matters because gout is linked to uric acid build-up, not just joint pain alone. The crystals can also cause kidney stones. Not everyone with high uric acid gets health problems, but in some people it can lead to gout.

When to Contact a Doctor

Talk to a doctor if you have joint pain, swelling, and redness, especially if it comes on in a flare. It is also a good idea to ask about your risk if you have conditions or medicines listed in the source, or a family history of gout.

Gout is often confused with pseudogout, but pseudogout is caused by calcium pyrophosphate, not uric acid.
