If I Am in Kidney Failure, Do I Have to Go on Dialysis?
When your kidneys fail, they can no longer filter waste, excess fluid, and toxins from your blood effectively. This condition, known as kidney failure or end-stage renal disease (ESRD), often raises a big question: Do I have to go on dialysis? And if so, what stage of kidney failure requires dialysis? Here’s what you need to know about kidney failure and dialysis.
Understanding Kidney Failure
Kidney failure happens when your kidneys lose most of their function—usually when they are working at less than 10%–15% of normal capacity. Without proper treatment, waste and fluid can build up in your body, leading to serious complications such as high blood pressure, anemia, and heart problems.
Dialysis: The Standard Treatment
Dialysis is the most common treatment for kidney failure. Dialysis is typically required when patients have reached Stage 5 of chronic kidney disease. Dialysis acts as an artificial kidney, filtering waste and excess fluid from your blood. There are two main types:
- Hemodialysis: With hemodialysis, your blood is filtered through a machine, usually at a dialysis center, several times per week.
- Peritoneal dialysis: With peritoneal dialysis, a special fluid is placed in your abdominal cavity, which absorbs waste and is then drained. This can often be done at home.
Dialysis is a lifesaving option for those who cannot get a transplant right away. It helps keep your body in balance and prolongs your life, but it isn’t a cure.
Are There Alternatives to Dialysis?
Not everyone with kidney failure has to start dialysis immediately. Options include:
- Kidney Transplant: A transplant is the most effective way to restore kidney function. If you’re a candidate, receiving a healthy kidney from a living or deceased donor can eliminate the need for long-term dialysis.
- Conservative or Supportive Care: Some patients—particularly those with other serious health conditions or older adults—may choose conservative management. This approach focuses on managing symptoms, maintaining quality of life, and avoiding dialysis. It involves careful monitoring, medications, dietary changes, and lifestyle adjustments.
When Dialysis Becomes Necessary
Your healthcare team will monitor your labs and symptoms closely to determine the right time to go on dialysis. You may be able to delay going on dialysis if your kidneys are still functioning well enough to manage waste and fluid balance.
Dialysis may become essential when:
- Waste products build up to dangerous levels
- Fluid retention causes swelling or shortness of breath
- Electrolyte imbalances affect your heart or other organs
- You experience severe fatigue, nausea, or confusion
Questions to Discuss With Your Doctor
If you’re facing kidney failure, talk with your nephrologist about:
- Whether dialysis is necessary now or can be delayed
- Transplant options and eligibility
- How lifestyle and diet can help manage kidney function
- Quality-of-life considerations
Not every patient with kidney failure has to go on dialysis immediately, but without some form of treatment—dialysis or a transplant—kidney failure is life-threatening. Understanding your options and working closely with your healthcare team can help you make the best decision for your health and lifestyle.
