Four Stages Of Gouty Arthritis
- Asymptomatic Hyperuricemia: In this stage, which usually doesn't require treatment, a person has elevated blood uric acid levels but no other symptoms.
- Acute Gout / Acute Gouty Arthritis: In this stage, hyperuricemia has caused deposits of uric acid crystals in joint spaces, leading to gouty attacks.
- Interval / Intercritical: In this stage, the periods between acute gouty attacks, a person has no symptoms.
- Chronic Tophaceous Gout: In this stage, the disease has caused permanent damage. With proper treatment, most never progress to this advanced stage.
