A middle-aged man, who went to bed with everything normal, woke up in the middle of the night and suddenly felt redness, swelling, epidermal heat and pain like cutting in the first metatarsophalangeal joint of the right lower limb, and when he got up in the morning, he could not move on the ground. The pain in the joint was relieved quickly after treatment. What is gouty arthritis? Gouty arthritis is caused by a metabolite called purine in a high-protein diet. When purine metabolism is disturbed, its product uric acid increases, and when uric acid increases in the blood, it is easily deposited in the joint cavity, synovial membrane and cartilage, causing recurrent attacks of gouty arthritis. If uric acid is deposited in the kidneys, it causes damage to kidney function. Most attacks of gouty arthritis are related to diet. If you eat too much high purine diet, such as seafood, animal offal, bean products, fish, shrimp, crab, chicken, lamb, beer, etc. During an attack of gouty arthritis, nearly 70% of patients experience sudden onset of redness, swelling, heat, pain, and restricted movement in the first metatarsophalangeal joint or ankle joint.
