Uric acid forms when the body breaks down purines in foods. Some foods also contain purines. Sometimes the body makes too much uric acid. It may also have problems passing uric acid out of the body through the kidneys. Uric acid crystals form when uric acid levels get too high. This leads to gout.
Gout is more common in men and older adults.
The main risk factor is having high levels of uric acid in the blood. Other things that may raise the risk are:
Eating foods high in purines, such as red meat, seafood, and alcohol
Eating or drinking things that are high in fructose, such as sugary drinks
Some medicines, such as diuretics, cyclosporin, and chemotherapy drugs
