Hemodialysis for kidney disease can bring down blood creatinine. Hemodialysis is one of the renal replacement therapy modalities, replacing the kidneys to remove part of the toxins, maintain electrolyte balance and remove excess water from the body. If the patient is in acute renal failure, after timely hemodialysis treatment, the kidney function will gradually recover and creatinine can be maintained at a certain level or completely normal, after which dialysis treatment may not be needed. If the patient has chronic renal failure, the blood creatinine will rise again because the kidney is seriously damaged, and regular hemodialysis treatment is needed. Kidney disease patients are advised to go to regular hospitals for timely consultation and targeted treatment or therapy under doctor’s guidance.
