High uric acid does not necessarily mean bad kidney. High uric acid may have a variety of reasons, mainly for increased uric acid production or decreased uric acid excretion. 1. Increased production of uric acid: intake of more purine-rich foods such as animal liver, kidney, anchovies, etc.; or leukemia, malignant tumors, cytotoxic drugs, chemotherapy, hemolysis, rhabdomyolysis, strenuous exercise, severe epilepsy, myocardial infarction, acute respiratory failure, etc. may produce a large number of purines, causing hyperuricemia. 2. Decreased excretion of uric acid: about 2/3 of uric acid is excreted through the kidneys, and the remaining 1/3 is excreted through extra-renal pathways such as the intestines and biliary tract. Therefore, when kidney function is impaired, it may lead to high uric acid levels. If patients find high uric acid, it is recommended to go to regular hospitals in time and standardize the treatment under the guidance of doctors.
