Creatinine 230μmol/L may recover if it is caused by acute renal failure, and generally cannot recover if it is caused by chronic kidney disease. If the patient’s creatinine 230μmol/L is caused by acute renal failure, it can be recovered if it is treated timely and effectively. If the patient’s creatinine 230μmol/L is caused by chronic kidney disease, it proves that the patient’s condition has been more serious, and the chances of recovery are not great. Patients should keep a good mindset and take the initiative to cooperate with doctors for treatment, meanwhile, they should pay attention to the dietary rules, consume chicken, lean meat and other high-quality proteins, and eat less high purine food such as pig liver, shellfish or fish, so as not to aggravate the condition, in addition, they should control the intake of water, and should not consume too much at one time. It is recommended that patients with elevated creatinine go to regular hospitals on a regular basis and follow the doctor’s instructions for standardized treatment.
