Kidney dialysis: Here's what you need to know
Dialysis is a lifesaving medical treatment for people whose kidneys can no longer efficiently filter waste, toxins and excess fluids from the blood.
Kidney dialysis is a crucial medical treatment for individuals whose kidneys are unable to effectively filter toxins, waste, and excess fluids from their blood. This condition, known as kidney failure, can arise from various factors such as diabetes, high blood pressure, glomerulonephritis, or genetic disorders.
Dialysis serves as an artificial kidney, taking over the vital functions of the failing kidneys and maintaining the necessary balance within the body. There are three primary types of dialysis: in-center hemodialysis, performed at a specialized dialysis center by trained medical staff; home hemodialysis and peritoneal dialysis, both of which can be performed at home, offering patients greater independence and flexibility.
Hemodialysis necessitates travel to a dialysis center at set intervals, typically three times a week. In contrast, home hemodialysis and peritoneal dialysis provide more scheduling flexibility and fewer dietary restrictions. Peritoneal dialysis utilizes the lining of the abdomen as a natural filter and does not require equipment installation or a partner present at home.
The choice of dialysis method depends on a patient's personal health, lifestyle, and preferences, often discussed in detail with their kidney doctor. Regardless of the chosen method, patients and their care teams collaborate to ensure the best possible outcome, adjusting the treatment plan as necessary.
Dialysis can impact a patient's diet, limiting intake of certain foods and nutrients like salt, potassium, phosphorus, and fluids, while maintaining adequate protein levels. Plant-based diets with lean protein intake, as recommended by a doctor and nutritionist, can promote overall health. Patients should avoid processed and factory-made foods to maintain a heart-healthy diet.
While dialysis can lead to various side effects, such as cramping and feelings of fatigue, patients undergoing home dialysis may experience fewer side effects due to more frequent treatment sessions. These sessions allow for steadier fluid management and fewer fluctuations, resulting in less fatigue or swelling.
Dialysis teams, comprising doctors, social workers, dietitians, and nurses, provide comprehensive care to address the patient's overall needs. Patients are encouraged to maintain an active and fulfilling life, including traveling with family and friends. In some cases, ocean cruise ships even have dialysis machines on board.
Ultimately, kidney transplantation is considered the preferred long-term solution for kidney failure. For eligible patients, dialysis can serve as a bridge until they receive a transplanted kidney. Post-transplant, patients may require immunosuppressant medications to prevent organ rejection.
