Stage 5 is the worst and final stage of chronic kidney disease (CKD), also called end-stage kidney disease or kidney failure. At this point, your kidneys are filtering less than 15% of what healthy kidneys would, measured by an estimated glomerular filtration rate (eGFR) below 15. Most people at this stage need dialysis or a kidney transplant to survive.
Understanding what stage 5 looks like, how it feels, and what options exist can help you or someone you care about prepare for what comes next.
How Kidney Disease Stages Work
Chronic kidney disease is divided into five stages based on eGFR, a number that estimates how well your kidneys filter waste from your blood. A healthy eGFR is above 90. Stage 1 and 2 involve mild damage that most people don’t feel. Stage 3 (eGFR 30 to 59) is when symptoms like fatigue and swelling often first appear. Stage 4 (eGFR 15 to 29) brings more noticeable problems and usually triggers planning for dialysis or transplant.
Stage 5, with an eGFR below 15 confirmed over at least three months, means your kidneys can no longer keep up with the body’s needs. Waste products, fluids, and minerals build up in the blood, affecting virtually every organ system.
What Stage 5 Feels Like
When kidneys fail, toxins accumulate in the bloodstream, a condition called uremia. Nausea, vomiting, and loss of appetite are usually the first symptoms people notice. From there, the list grows: unexplained weight loss, deep fatigue, shortness of breath, muscle cramps, persistent itching, and a metallic taste in the mouth. Many people also experience difficulty thinking clearly or remembering things.
Without treatment, uremia becomes severe. Breath can develop an ammonia-like smell. Yellow-white crystals may appear on the skin after sweating. Inflammation around the heart can cause chest pain. In the most extreme cases, toxin buildup in the brain leads to seizures or coma. These severe symptoms are rare in people already receiving treatment, but they illustrate why stage 5 requires intervention.
Complications Beyond Toxin Buildup
Kidney failure doesn’t just mean waste accumulation. The kidneys also regulate hormones and minerals that keep bones strong. When they can no longer do this, calcium and phosphorus levels fall out of balance, and bones become weak and misshapen over time. This is called mineral and bone disorder, and it’s common in stage 5. Treatment typically involves medications that restore mineral balance, along with dietary changes like avoiding packaged foods that contain phosphorus-based preservatives (look for ingredients with “PHOS” on the label).
Anemia is another frequent complication. Healthy kidneys produce a hormone that signals your body to make red blood cells. When that signal weakens, you end up with fewer red blood cells, which compounds the fatigue and shortness of breath already caused by uremia.
Treatment Options at Stage 5
At this stage, the primary options are dialysis or kidney transplant. The choice depends on your overall health, lifestyle, and personal preferences.
Dialysis
Dialysis takes over the filtering work your kidneys can no longer do. There are two main types. Hemodialysis cycles your blood through an external machine that removes waste and returns the cleaned blood to your body. It requires a surgically created access point, usually in the arm, where an artery and vein are connected. That minor surgery takes about 1 to 1.5 hours. Most people on hemodialysis go to a clinic three times a week for sessions lasting several hours each.
Peritoneal dialysis works differently. A special fluid is placed into the open spaces in your abdomen, where it absorbs waste through the abdominal walls before being drained. This can be done continuously during the day or overnight using a machine called a cycler, which gives some people more flexibility than hemodialysis.
Five-year survival on dialysis is roughly 41%, according to data from the United States Renal Data System. That number has stayed fairly stable over the past decade, hovering around 40 to 42% regardless of whether someone is on hemodialysis or peritoneal dialysis.
Kidney Transplant
A transplant offers significantly better long-term survival. Five-year survival after receiving a kidney from a living donor is about 91.5%. For a deceased donor kidney, it’s around 80%. The gap reflects both the quality of the organ and the fact that living donor kidneys can be transplanted more quickly, before the body accumulates years of damage on dialysis.
The catch is access. The national median wait time for a deceased donor kidney is about 30 months, though in more populated areas it can stretch to 10 years depending on blood type. A living donor, if available, dramatically shortens that timeline.
Dietary Changes in Stage 5
Diet becomes tightly controlled at this stage. The general recommendation is a daily limit of about 2 grams of sodium and 2 grams of potassium, along with strict phosphorus restriction. Saturated fat and cholesterol are also limited. These restrictions help manage blood pressure, protect bones, and reduce the workload on whatever kidney function remains.
For people on dialysis, a low-sodium diet can sometimes control blood pressure without medication, though many patients still need blood pressure drugs. Practically, this means reading every food label, cooking most meals from scratch, and working closely with a dietitian who specializes in kidney disease.
Choosing Not to Start Dialysis
Not everyone with stage 5 CKD chooses dialysis or transplant. For some people, particularly those who are older or have other serious health conditions, the burden of treatment may outweigh the benefits. Conservative management focuses on quality of life and symptom control rather than replacing kidney function.
This approach involves preserving whatever kidney function remains for as long as possible, managing symptoms like nausea and poor appetite, treating complications like anemia, and minimizing hospital stays that could worsen quality of life. Palliative care addresses physical, emotional, and spiritual needs. It often means fewer medical appointments, fewer blood draws, and fewer medications, with the goal of making the time you have as comfortable as possible. It also includes planning for end-of-life care on your own terms.
Conservative management is not giving up. It’s a deliberate choice that some people and their families make after weighing all the options.
How Fast Stage 5 Progresses
The pace of decline varies enormously. Some people live for years on dialysis. Others reach stage 5 quickly after a long, slow decline through earlier stages. The speed depends on what caused the kidney disease in the first place (diabetes and high blood pressure are the two most common causes), how well other conditions are managed, and individual biology.
What’s consistent is that stage 5 requires active decision-making. Whether that means starting dialysis, pursuing a transplant, or choosing conservative management, the choices made at this stage shape both how long and how well someone lives.
