Stage 4 kidney disease (CKD) isn't always considered terminal, but it's a severe, advanced stage where kidney function is significantly reduced, making progression to Stage 5 (End-Stage Renal Disease) likely, requiring dialysis or transplant; while there's no cure, treatment focuses on slowing damage and managing complications, but many people die from heart disease or other related issues before kidney failure, making careful management crucial for quality and length of life.
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.
There is no cure for kidney failure, but with treatment it is possible to live a long, fulfilling life.
Symptoms of Stage 4 CKD may include: Feeling weak and tired. Swelling in your arms or legs. Urinating more or less often than normal.
SGLT2-Inhibitors (Flozins)
SGLT2 inhibitors are FDA-approved to help lower blood sugar in adults with type 2 diabetes and people with kidney disease with an eGFR as low as 20 (CKD stage 4).
We found that participants with progressive CKD spent a median of 7.9 years in stage 3a, 5 years in stage 3b, 4.2 years in stage 4, and <1 year in stage 5.
Over-the-counter NSAIDS
They are not safe to use when you have kidney disease. Ibuprofen, such as Advil™ and Motrin™. Naproxen, such as Aleve™ and Naprosyn™. Aspirin for pain relief.
Kidney pain strikes below the rib cage on either side of the spine and can feel like it is coming from deep inside the body. It's common to feel pain on one or both sides of the body, depending on whether the trouble is in one or both of these bean-shaped organs.
A standard test to diagnose the stage of CKD is a blood test that determines the estimated glomerular filtration rate (eGFR), which indicates kidney function. In CKD stage 4, the eGFR is between 15 and 29 ml/min.
Managing stage 4 CKD
Patients should talk to their doctors about an exercise plan. Doctors can also provide tips on how to stop smoking. The National Kidney Foundation (NKF) guidelines recommend starting dialysis when kidney function drops to 15 percent or less.
High levels of metabolic waste products in the blood can damage nerve cells in the brain, trunk, arms, and legs. Uric acid levels may increase, sometimes causing gout. Diseased kidneys cannot excrete excess salt and water. Salt and water retention can contribute to high blood pressure and heart failure.
How to manage kidney disease by being active
Your kidneys filter your blood and send waste products out of your body in urine (pee). When your kidneys don't work correctly, waste products build up in your body. If this happens, you'll feel sick and eventually die without treatment.
People with certain kidney disorders (such as interstitial nephritis or kidney damage resulting from sickle cell anemia) may also urinate excessively because these disorders also decrease the amount of fluid reabsorbed by the kidneys. Rarely, urinary frequency is caused by spinal cord injury or disorder.
Chronic kidney disease usually progresses slowly. Regular blood and urine tests can help doctors to decide whether the kidneys are still working well enough, whether the treatment needs to be adjusted, or whether dialysis will be needed soon, for example.
Canned foods, some frozen foods, and most processed meats contain large amounts of salt. Snack foods such as chips and crackers are also high in salt. Table salt, some seasonings, ketchup, mustard, and certain sauces such as barbecue, soy, and teriyaki sauces are high in sodium.
Fluid intake targets are individualised in stages 4 and 5 CKD and depend on the amount of residual kidney function, type of dialysis undertaken, and diuretic therapy. When prescribed, fluid restrictions are typically 1000 to 1500 mL/day.
Eggs and Kidney Disease
Eggs are a good source of animal protein and phosphorus, which you may need to limit in CKD. Ask your kidney dietitian how many eggs are safe to eat. Eggs are low in sodium and potassium which may be helpful.

Kidney Failure Skin Color
One common change is a yellowing of the skin, known as jaundice. This is caused by a buildup of bilirubin, a waste product that is normally excreted by the liver. Jaundice can cause the skin and whites of the eyes to turn yellow.
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.
Top 10 Drugs That Cause Kidney Damage
Sleeping on Your Back: While sleeping on your back is not the best position for everyone, it is highly recommended for kidney patients. This position allows the body to maintain a natural alignment, placing less pressure on the kidneys.
