A bad kidney function number usually means an eGFR (estimated Glomerular Filtration Rate) below 60 mL/min, indicating potential kidney disease, with levels under 15 signaling kidney failure, requiring dialysis or transplant; higher numbers are better, as normal function is generally 90+, but can decline with age. A low eGFR suggests the kidneys aren't filtering waste well, with specific stages defined by the number: <60 (disease), 15-29 (severe loss), <15 (failure).
A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.
Severe loss of kidney function, eGFR of 15–29
At this stage of chronic kidney disease (CKD), it's important to manage your health as best you can to preserve kidney function and start planning ahead for potential treatments like a kidney transplant or dialysis.
Kidney disease in children is diagnosed the same way it is in adults. A urine test, blood test, imaging test or kidney biopsy can help determine if something is wrong with the kidneys. The eGFR (estimated glomerular filtration rate) blood test shows how well the kidneys are working.

Certain conditions may cause a person to have higher than normal levels of creatinine. People with only one kidney may have a normal creatinine level of about 1.8 or 1.9. Creatinine levels of 2.0 or more in infants and 5.0 or more in adults may indicate severe kidney damage.
By comparing the blood and urine level of this substance, the doctor has an accurate idea of how well the kidneys are working. This result is called the creatinine clearance. Usually, when the creatinine clearance falls to 10-12 cc/minute, the patient needs dialysis.
What are the symptoms of kidney disease in children?
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.
Three key early warning signs of kidney problems are changes in urination (more or less frequent, especially at night), foamy or bloody urine, and persistent swelling, particularly around the eyes, feet, or ankles, indicating fluid retention. Other common signs include persistent fatigue, nausea, itching, and loss of appetite, as toxins build up when kidneys aren't filtering effectively.
Treatments can involve diet changes or medications. Treatments also vary with the type of kidney disease. However, if these problems become too severe, dialysis may be necessary. Hemodialysis uses a machine to clean the blood to make up for the loss of kidney function.
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.
The damage that occurs in CKD is more permanent. So, people with CKD are less likely to see their eGFR number go up, even if it is treated. In CKD, your eGFR number may not go back up. This does not mean there is nothing you can do to help!
If your kidney function drops below 15 percent of normal, you are said to have kidney failure. You may have symptoms from the buildup of waste products and extra water in your body. To replace your lost kidney function, you may have one of three treatment options: hemodialysis.
Yes, end-stage renal failure can lead to death. With the right treatment, most people can live with kidney failure. It's important to remember that there's no cure for kidney failure. That means even with treatment, your kidneys won't go back to functioning as they did before you had kidney disease.
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol, while also managing blood pressure and blood sugar to prevent damage.
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.
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.
Generally, earlier stages are known as 1 to 3. And as kidney disease progresses, you may notice the following symptoms. Nausea and vomiting, muscle cramps, loss of appetite, swelling via feet and ankles, dry, itchy skin, shortness of breath, trouble sleeping, urinating either too much or too little.
Itching often happens on both sides of the body at the same time (for example, both arms or both legs). Itching is most common and severe in people with kidney failure,but those in the earlier stages of CKD may also notice milder itching.
Kidney disease can affect anyone at any age. Babies can be born with kidneys that haven't developed normally or don't function normally. Genetic alterations can result in kidney diseases developing during childhood or later in life. Other types of kidney disease can develop at any age.
Chronic kidney disease and treatment
There are five Stages of CKD, with the most advanced being Stage 5, with an estimated glomerular filtration rate (eGFR) of less than 15. It is generally patients with Stage 5 CKD that are considered candidates to start dialysis therapy or be considered for kidney transplantation.
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.
