In general, we classify gout patients according to their disease development into four types: acute gouty arthritis, asymptomatic hyperuricemia, gout stones and chronic arthritis, and renal lesions. Acute gouty arthritis attacks are very typical, with a rapid onset, waking up in the middle of the night with foot pain, and developing to peak symptoms within a few hours Local injuries to the joints such as foot sprains, walking more in tight shoes and surgery, full meals and alcohol, excessive fatigue, exposure to cold and moisture, and infections may be triggering factors. Asymptomatic hyperuricemia is usually the remission period of gouty arthritis, which is the intermittent period of gout. In this stage, only high uric acid and no joint pain occur, but if abnormal fluctuations of uric acid occur, such as sudden overeating, it may trigger acute gouty arthritis again. If the condition of a gout patient is not well controlled, uric acid deposits in the joints increase, and gout stones form around the joints, resulting in stiff and deformed joints, restricted movement, and gout nodules (or gout stones) around the joints. About 1/3 of patients with prolonged gout have kidney damage, manifesting as gouty nephropathy, acute renal failure, and urinary stones.
