Stage 4 kidney disease (CKD) isn't automatically terminal, but it's a severe condition where kidneys are failing, progressing towards Stage 5 (End-Stage Renal Disease, or ESRD), which requires dialysis or transplant to survive long-term, and it significantly shortens life expectancy, with many dying from heart disease or complications before kidney failure itself. While there's no cure, dedicated management can slow progression and improve quality of life, but it's a serious illness with a reduced life expectancy, especially without treatment.
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.
Stage 4 CKD means that your kidneys are moderately or severely damaged and are not properly filtering waste from your blood. When your kidneys aren't properly filtering waste products like urea and creatinine from your blood, it can lead to a condition called uremia.
There is no cure for kidney failure, but with treatment it is possible to live a long, fulfilling life. Having kidney failure is not a death sentence. People with kidney failure live active lives and continue to do the things they love.
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).
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.
If you have diabetes, controlling your blood glucose (blood sugar) levels may help slow the progression of kidney disease. Adopt a diabetes- and kidney-friendly diet, and follow the instruction of your doctor when it comes to diet, insulin, or other medications.
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.
How to manage kidney disease by being active
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.
Symptoms of stage 4 kidney disease
Urination changes (foamy; dark orange, brown, tea-colored or red if it contains blood; and urinating more or less than normal) Kidney pain felt in their back. Sleep problems due to muscle cramps or restless legs. Nausea and/or vomiting.
A severe decrease in kidney function can lead to a buildup of toxins and impurities in the blood. This can cause people to feel tired or weak and can make it hard to concentrate. Another complication of kidney disease is anemia, which can cause weakness and fatigue.
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.
In stage 4 CKD, you are at the highest risk for having kidney failure and you are at very high risk for heart disease (even if your uACR is lower than 30). As your uACR number goes up, your risks of developing heart disease and kidney failure both go up.
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.
Sleeping on Your Side: Sleeping on your side is another suitable option for kidney patients. It helps improve blood flow, which can better the kidney functions. It is recommended to sleep on your left side to promote optimal blood circulation which will help reduce the workload on kidneys.
Heart disease, uncontrolled high blood pressure or diabetes can make kidney disease get worse faster. So it is important that your doctor keeps an eye both on how your kidneys are working and your overall health.
To support kidney health, focus on fruits like berries, apples, and red grapes; vegetables such as cauliflower, red peppers, and leafy greens; lean proteins like fish (salmon) and egg whites; and healthy fats from olive oil, using herbs and spices instead of salt for flavor, as a varied diet rich in whole foods helps filter toxins and manage inflammation.
Medicines that may need to be avoided, adjusted, or changed include:
How does sugar affect the kidneys? Sugar is not a problem for the kidneys unless the blood sugar level gets too high. This commonly occurs in both Type 1 and Type 2 diabetes. Once the blood sugar level gets higher than 180 mg/dl, the kidneys start to spill sugar into the urine.
In large, population-based studies with long-term follow-up, a proportion of patients with CKD undergo regression or remission over time. The likelihood of remission, however, is strongly associated with the presence and severity of albuminuria.
Special renal vitamins are usually prescribed to provide extra water soluble vitamins needed. Renal vitamins contain vitamins B1, B2, B6, B12, folic acid, niacin, pantothenic acid, biotin and a small dose of vitamin C.
Top 10 Drugs That Cause Kidney Damage
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
