What are the symptoms of hyperuricemia?

The symptoms of hyperuricemia can be divided into different types. Generally, patients need to check their arthritis and check their usual urine excretion. In addition, after contracting this disease, the main symptoms will be joint pain or even joint swelling.

Typical symptoms

Asymptomatic hyperuricemia refers to patients who only have hyperuricemia (serum uric acid level >420 μmol/L and 360 μmol/L in men and women, respectively) but no clinical symptoms such as arthritis, tophi, and uric acid stones. The incidence rate in adult males is 5% to 7%. The patient had never had an attack of gouty arthritis, but during a physical examination, it was accidentally discovered that the uric acid level in the blood was high.

Diagnosis

1. Under the standard normal purine diet state for hyperuricemia, the fasting blood uric acid levels on two different days are greater than 416.5μmol/L for men or greater than 357μmol/L for women.

2. Classification diagnosis of hyperuricemia Classification diagnosis helps to discover the cause of hyperuricemia and provide targeted treatment. After 5 days of low-purine diet, patients with hyperuricemia should collect urine for 24 hours to test uric acid levels. (1) Uric acid excretion is less than 2.86 μmol/(kg·h) and uric acid clearance rate is less than 6.2 ml/min. (2) Overproduction of uric acid: uric acid excretion is greater than 3 μmol/(kg·h), and uric acid clearance rate is greater than or equal to 6.2 ml/min. (3) Mixed uric acid excretion exceeds 3 μmol/(kg·kh) and uric acid clearance rate is less than 6.2 ml/min.
