Prolonged excessive drinking may lead to kidney crystallization. When long-term excessive drinking, as alcohol in the body will be decomposed into lactic acid under the action of various enzymes, the increase in the content of lactic acid may affect the excretion of uric acid, which will lead to the increase of uric acid concentration in the patient’s body. And uric acid is mainly metabolized through the kidneys, when uric acid is too high it may precipitate crystals in the kidneys, which may cause kidney crystals. Patients with high uric acid caused by long-term alcohol consumption should try to avoid purine-containing foods and beverages in their daily diet, such as animal offal, beer, carbonated beverages, spinach, seafood and so on. If necessary, follow the doctor’s instructions to take benzbromarone tablets and other drugs to promote uric acid discharge, the application of sodium bicarbonate tablets to alkalize the urine. If the patient is diagnosed with renal crystallization, it is recommended to seek immediate medical attention to clarify the nature of renal crystallization and actively cooperate with the doctor’s treatment.
