Uric acid is a metabolite of purine-based foods in the body. Uric acid is generally high and common in clinical practice, and low uric acid is rare in clinical practice. Patients with high uric acid have high uric acid because they have improved their standard of living and eat too much big fish and meat. Low uric acid may be related to a slower and lower metabolism in general, or eating less purine-containing foods. Low blood uric acid has no obvious harm to the organism; you can eat appropriate high purine foods such as fish and meat, keep a balanced diet and avoid malnutrition, and uric acid will return to normal.”
