The last stage before kidney failure (Stage 5) is Stage 4 Chronic Kidney Disease (CKD), a period of severe kidney damage where kidneys function at only 15-29% capacity, requiring preparation for future dialysis or transplant as waste builds up, leading to significant symptoms like fatigue, swelling, and shortness of breath, notes this article from the National Kidney Foundation and Yale Medicine, respectively.
Understanding Kidney Failure and its Final Stages
The final stage is end-stage renal disease (ESRD) or end-stage kidney failure. As many as 808,000 people are living with ESRD. [3] When a person reaches this stage of kidney disease, without any treatment they will die within weeks to days.
What are the first warning signs of kidney failure?
Patients may experience a wide variety of symptoms as kidney failure progresses. These include fatigue, drowsiness, decrease in urination or inability to urinate, dry skin, itchy skin, headache, weight loss, nausea, bone pain, skin and nail changes and easy bruising.
Stage 5 CKD means you have kidney failure (also known as end-stage kidney disease or ESKD). People with stage 5 CKD have an estimated glomerular filtration rate (eGFR) less than 15 for 3 months or more (confirmed with repeat testing to make sure you don't have acute kidney injury) or they are on dialysis.
Key Warning Signs That You May Need Dialysis Soon
For someone around 60, stage 1 stage 2 kidney disease life expectancy will be approximately 15 years. That figure falls to 13 years, 8 years, and 6 years in the second, third, and fourth stages of kidney disease, respectively.
Kidney damage, once it occurs, can't be reversed. Potential complications can affect almost any part of your body and can include: Fluid retention, which could lead to swelling in your arms and legs, high blood pressure, or fluid in your lungs (pulmonary edema)
Sleep disorders, are common in people with chronic kidney disease and end stage renal disease. In addition to insomnia, sleep-disordered breathing, excessive sleepiness, and restless leg syndrome many have a high incidence of sleep apnea and periodic limb movements in sleep.
People with kidney failure may survive days to weeks without dialysis, depending on the amount of kidney function they have, how severe their symptoms are, and their overall medical condition. Is death from kidney failure painful? Not usually. If you do feel any discomfort, pain medication may be prescribed for you.
You feel kidney pain near the middle of your back, just under your ribcage, on each side of your spine where your kidneys are. Your kidneys are part of the urinary tract, the organs that make and remove urine from the body. (pee). You may feel kidney pain on one or both sides of your back.
Causes. The two main causes of kidney failure are diabetes and high blood pressure, which make up about two-thirds of cases. Other diseases can also lead to kidney failure, including IgA nephropathy, lupus nephritis, polycystic kidney disease, Fabry disease, and many others.
The main test for kidney disease is a blood test. The test measures the levels of a waste product called creatinine in your blood. A doctor uses your blood test results, plus your age, size, and gender to calculate how many millilitres of waste your kidneys should be able to filter in a minute.
Some of the most common end-of-life kidney failure signs include:
As people get closer to dying, they may sleep more, become drowsy or be difficult to wake. They may fall asleep while talking. A person may slowly lose consciousness in the days or hours before death.
While early kidney disease often has few signs, three key early warning signs to watch for are changes in urination (more/less frequent, foamy, or bloody), persistent fatigue, and swelling in hands, feet, or ankles, all pointing to the kidneys struggling to filter waste and excess fluid. These symptoms, along with others like itchy skin, poor appetite, or trouble concentrating, signal a need to see a doctor for proper testing.
Possible symptoms of decreasing kidney function and why they occur later
You can check kidney function at home using at-home test kits for urine (detecting protein/albumin) or finger-prick blood tests (checking creatinine/eGFR), often with smartphone apps for analysis, or by monitoring symptoms like increased nighttime urination (nocturia), swelling, or changes in urine (blood, foam) and discussing results with a doctor, as home tests screen but don't replace professional diagnosis.
There is growing evidence that changes in sleep duration and time of sleep onset may have detrimental effects on renal function. Short sleep duration and shift work are associated with risk factors for chronic kidney disease (CKD), including hypertension, diabetes, and cardiovascular disease.
In some cases, sepsis can develop within 24 to 48 hours after the onset of severe symptoms, especially if medical intervention is delayed.
One of the earliest signs of kidney failure is persistent fatigue and weakness. As kidney function declines, waste products build up in the blood, leading to a general feeling of tiredness and lack of energy.
When should I start dialysis? National Kidney Foundation guidelines recommend you start dialysis when your kidney function drops to 15% or less — or if you have severe symptoms caused by your kidney disease, such as: shortness of breath, fatigue, muscle cramps, nausea or vomiting.
It is likely someone with stage 4 CKD will need dialysis or a kidney transplant in the near future as part of their treatment.
