Gout attack will cause redness, swelling, heat and pain in one or more joints, local swelling of the joint is obvious and cannot be tolerated, resulting in limping and even the production of uric acid crystals in the joint. This can lead to deformation of the joint. Long-term hyperuricemia and gout attacks can lead to joint deformities, joint destruction, joint abnormalities, and even crystals deposited in the ureter and kidney, causing urinary stones, such as kidney stones, ureteral stones, and so on. Therefore, people with high uric acid are advised not to drink beer and not to eat foods high in purines.
