Uric acid is below normal, usually does not cause any disease, but may indicate the presence of renal tubular function damage, liver function is seriously impaired and other problems. 1. Uric acid is a product of the body’s nucleic acid purine metabolism, and because it is a metabolic waste product, its lowering generally does not cause any major problems. 2. However, when uric acid is lowered, it may indicate the presence of certain diseases. (1) If renal tubular function is impaired, it will lead to reduced reabsorption or (and) increased secretion in the proximal renal tubules, which will easily lead to a decrease in the concentration of blood uric acid, thus causing renal hypouricemia. (2) If liver function is severely impaired, purine catabolism will be impaired, resulting in a decrease in uric acid production, and therefore a decrease in blood uric acid. If this situation is found, it is recommended to consult a doctor in time to clarify the condition under the guidance of a professional doctor. Uric acid lower than normal value generally does not lead to any serious diseases, but the lowering of uric acid has a certain clinical significance, it is recommended to consult a doctor in a timely manner.
