Gout is a common type of arthritis. It is a painful and potentially debilitating condition that develops from deposits of uric acid crystals in the joints. 1,2 The accumulation of crystals causes attacks of painful inflammation in and around the joints. 3 Not everyone with high blood uric acid levels (called hyperuricaemia) develops gout. Up to two-thirds of individuals with hyperuricaemia never develop symptoms. It is unclear why some people with hyperuricaemia develop gout while others do not, but the symptoms of gout result from the body’s reaction to deposits of uric acid crystals in the joints. 1
