Gout is a disease caused by increased concentration of uric acid in the blood due to impaired purine metabolism in the body, excessive production of uric acid or/and decreased excretion of uric acid. The first stage of gout is asymptomatic hyperuricemia, the second stage is acute gouty arthritis, and the third stage is gouty stone and chronic gouty arthritis. 1. Asymptomatic hyperuricemia: in this stage, there is only fluctuating or persistent hyperuricemia, the patient’s body has purine metabolism disorder, which will lead to the body’s production of uric acid, hyperuricemia. 2. Acute gouty arthritis: impaired purine metabolism in the body will lead to excessive uric acid production, uric acid deposition and formation of crystals, it will stimulate the joints, resulting in joints, redness, swelling, heat, pain and dysfunction, and can be accompanied by fever. 3. Gout stone and chronic gouty arthritis: uric acid deposits form gout stone, gout stone will cause chronic inflammatory lesions in the tissues around the joints. Gout patients are recommended to go to the hospital in time, under the guidance of the doctor for treatment.
