Gout is a rheumatic disease caused by metabolic disorders and belongs to the category of paralysis in Chinese medicine. In the acute stage, dampness and heat paralysis are common. The incidence rate is 2-8%. Gout mostly occurs in men, accounting for 95% of the cases, and the age of onset is 30-60 years old. Gout is rare in women, accounting for only 5% of cases, and mostly in menopausal women, and is extremely rare in young women. Gout is more common in Europe and the United States, but with the improvement of living standards and changes in diet structure, the incidence of gout in China has increased, and there is a trend towards younger people. A survey shows that the incidence of gout in people over 30 years old with hyperuricemia is 17.3%. Gout patients are clinically divided into acute gouty arthritis and chronic gouty arthritis. Acute gouty arthritis can be caused by heavy alcohol consumption, seafood, animal offal, strenuous exercise, cold and other triggers. If repeated attacks cannot be relieved, chronic gouty arthritis is likely to develop. The main clinical manifestations of gout Acute gouty arthritis has very typical manifestations, especially the first attack is mostly acute at night, manifested as one side of the metatarsophalangeal joint redness and swelling severe pain, the degree of pain is unbearable, can not be touched by any substance, this pain lasts a few hours, at most a day, usually 24 hours to reach the peak, without treatment will gradually reduce the pain, 2-5 days can be self-relieved. The pain disappears without leaving any trace at all and can be without any discomfort. There can be an interval of several months or 1-2 years until the second attack, and longer intervals of 3-5 years. The symptoms of the second attack are similar to those of the first attack, and the area of redness and pain can be the same as the first painful area, or it can be switched to the other foot, or to the dorsum of the foot, ankle joint, etc. The symptoms of localized redness and severe pain but if left untreated last longer than the first. Later, there can be a third, fourth or even more episodes with shorter and shorter intervals, and the site can alternate between left and right, or multiple joints such as the metatarsophalangeal joint, dorsal foot and ankle joint, or one site can have repeated episodes. The seizures are more frequent at night, and can also be significantly worse during the day and night. There is an obvious trigger before the attack, such as after eating hot pot, eating seafood, drinking beer, eating animal offal, having a nice meal, or after more strenuous and heavy activities such as hiking, running, playing soccer, participating in ball games, etc. Or cold stimulation, local trauma to the joints, etc. There are also elderly people who have acute gouty arthritis attacks without these triggers and have a history of taking diuretics or compounded antihypertensive drugs containing diuretics for a long time. Because some diuretics affect the excretion of uric acid, long-term use of uric acid levels rise in the body causing acute gouty arthritis attacks. Laboratory test indicators: elevated blood uric acid, is one of the most important diagnostic criteria.
