Gout is a form of inflammatory arthritis characterized by recurrent attacks of a red, tender, hot, and swollen joint.[4][5] Pain typically comes on rapidly, reaching maximal intensity in less than 12 hours.[8] The joint at the base of the big toe is affected in about half of cases.[10] It may also result in tophi, kidney stones, or kidney damage.[4]
Gout is due to persistently elevated levels of uric acid in the blood.[5][8] This occurs from a combination of diet, other health problems, and genetic factors.[4][5] At high levels, uric acid crystallizes and the crystals deposit in joints, tendons, and surrounding tissues, resulting in an attack of gout.[4] Gout occurs more commonly in those who regularly eat meat or seafood, drink beer, or are overweight.[4][6] Diagnosis of gout may be confirmed by the presence of crystals in the joint fluid or in a deposit outside the joint.[4] Blood uric acid levels may be normal during an attack.[4]
Treatment with nonsteroidal anti-inflammatory drugs (NSAIDs), steroids, or colchicine improves symptoms.[4][5][11] Once the acute attack subsides, levels of uric acid can be lowered via lifestyle changes and in those with frequent attacks, allopurinol or probenecid provides long-term prevention.[8] Taking vitamin C and eating a diet high in low-fat dairy products may be preventive.[12][13]
Gout affects about 1 to 2% of the Western population at some point in their lives.[8] It has become more common in recent decades.[4] This is believed to be due to increasing risk factors in the population, such as metabolic syndrome, longer life expectancy, and changes in diet.[8] Older males are most commonly affected.[4] Gout was historically known as "the disease of kings" or "rich man's disease".[8][14] It has been recognized at least since the time of the ancient Egyptians.[8]
