Can Diabetes Damage Your Kidneys? Yes. Diabetes can gradually damage the kidneys, particularly when blood glucose or blood pressure remains above the person’s recommended target over time. The condition is commonly called diabetic kidney disease or diabetic nephropathy. One important problem is that diabetes kidney damage symptoms may not appear during the early stages. A person may feel completely well while changes such as albumin leaking into the urine or a reduction in kidney filtration are already developing. This is why kidney testing is important even when there are no obvious symptoms. Patients with diabetes can learn more about the relationship between diabetes and kidney health through Diabetes & Kidney Diseases. Quick Answer Diabetes can damage the kidneys without causing early symptoms. Two of the most useful tests are a blood test used to calculate eGFR and a urine albumin-to-creatinine ratio (UACR). Protein or albumin in urine can sometimes appear before a major reduction in kidney filtration is detected. What Is Diabetic Kidney Disease? diabetes-kidney-tests-uacr-egfr-creatinine Diabetic kidney disease is kidney damage associated with diabetes. The kidneys contain tiny filtering structures that remove waste and extra fluid from the blood. Over time, diabetes can affect these filtering structures and the blood vessels supporting them. Kidney damage may lead to albumin or protein leaking into urine, changes in eGFR and, in some people, worsening chronic kidney disease. High blood pressure can further contribute to kidney damage, making blood pressure management particularly important for people with diabetes. For more information on long-term kidney-function problems, see Acute & Chronic Kidney Diseases. What Are the Early Signs of Kidney Damage From Diabetes? Early diabetic kidney disease often causes no noticeable symptoms. This is why waiting for physical symptoms is not a reliable way to protect kidney health. As kidney disease becomes more advanced, possible symptoms can include: – Swelling around the feet, ankles, hands or eyes – Foamy or unusually bubbly urine – Blood pressure becoming more difficult to control – Tiredness or weakness – Changes in urination – Reduced appetite – Nausea – Shortness of breath or increasing fluid retention These symptoms are not specific to diabetic kidney disease, so they should not be used for self-diagnosis. Persistent or unexplained symptoms require medical evaluation. Mayo Clinic similarly identifies swelling, foamy urine, harder-to-control blood pressure and fatigue among possible later-stage symptoms. What Tests Check for Diabetes-Related Kidney Damage? 1. Urine Albumin-to-Creatinine Ratio — UACR The UACR test looks for albumin, a blood protein, leaking into urine. Healthy kidneys normally keep most albumin in the bloodstream. Persistent elevation in urine albumin can be an early marker of kidney damage. Importantly, one abnormal result does not always establish chronic kidney disease because factors such as infection, strenuous exercise, fever, marked hyperglycemia, menstruation or very high blood pressure can temporarily increase UACR. The 2026 ADA guidance recommends confirming albuminuria when two of three samples within about 3–6 months are abnormal. 2. Serum Creatinine and eGFR Creatinine is measured with a blood test. The result is used with other information to estimate the glomerular filtration rate, or eGFR, which gives a better indication of kidney filtration than looking at creatinine alone. A normal-looking creatinine value does not always tell the entire story because creatinine can vary with factors such as muscle mass. This is one reason doctors interpret creatinine together with eGFR, urine results and the patient’s overall medical history. diabetic-kidney-disease-symptoms What Do UACR and eGFR Results Mean? Test result General interpretation UACR below 30 mg/g Normal to mildly increased albumin UACR 30–299 mg/g Moderately increased albuminuria UACR ≥300 mg/g Severely increased albuminuria eGFR ≥90 Normal/high filtration; kidney disease can still exist if other markers are abnormal eGFR 60–89 Mild reduction; interpretation depends on other evidence of kidney damage eGFR 30–59 Moderate to significant reduction eGFR 15–29 Severe reduction in kidney function eGFR below 15 Kidney failure range requiring specialist assessment An eGFR persistently below 60 mL/min/1.73 m² and/or persistent urine albumin above 30 mg/g can indicate chronic kidney disease. Results should be interpreted over time rather than from a single number, especially when kidney function is changing rapidly. How Often Should People With Diabetes Get Kidney Tests? According to the American Diabetes Association Standards of Care in Diabetes—2026, kidney function should generally be assessed with UACR and eGFR at least once a year in everyone with type 2 diabetes and in people with type 1 diabetes who have had diabetes for five years or longer. If chronic kidney disease is already present, monitoring may be required one to four or more times per year, depending on kidney stage, albuminuria, treatment and the patient’s clinical condition. Your doctor should decide the appropriate testing frequency. Why Is Early Detection Important? Detecting kidney changes before major symptoms develop gives the treating team an opportunity to assess possible causes and address factors that may contribute to further kidney damage. Management may involve improving diabetes control, managing blood pressure, reviewing medications, assessing cardiovascular risk and monitoring kidney function. Current diabetes guidelines also include kidney-protective therapies for selected patients, but treatment depends on factors such as eGFR, urine albumin, blood pressure, diabetes type, other health conditions and current medicines. Patients who also have difficult-to-control blood pressure can read about Resistant Hypertension. How Is Diabetic Kidney Disease Managed? There is no single treatment suitable for every patient. Management starts with identifying the degree of kidney involvement and controlling the conditions contributing to it. Depending on the patient’s situation, care may include individualized blood glucose management, blood pressure treatment, medication review, monitoring UACR and eGFR, dietary advice where appropriate and treatment of other cardiovascular or kidney risk factors. The aim is to protect remaining kidney function and reduce the risk of progression rather than promising a guaranteed reversal. Risks and Important Considerations People with diabetes should avoid assuming that every creatinine increase is automatically caused by diabetes. Other kidney diseases, dehydration, medicines, urinary obstruction, infection and acute illness can also affect kidney function. NIDDK specifically advises that diabetes should not automatically be assumed to be

Chronic kidney disease (CKD) can develop quietly. In its early stages, many people have no obvious symptoms, which is why abnormal blood pressure, urine protein, rising creatinine or a reduced eGFR may be noticed before a patient actually feels unwell. As kidney function declines, symptoms such as unusual tiredness, swelling, foamy urine, changes in urination, poor appetite or itching may appear. People with diabetes, high blood pressure, heart disease or a family history of kidney disease should not wait for symptoms before checking kidney health. Patients with abnormal kidney reports can seek evaluation from a nephrologist in Navi Mumbai or Vashi to understand whether further testing or monitoring is needed. What Is Chronic Kidney Disease? Early Signs of Chronic Kidney Disease Chronic kidney disease is a long-term condition in which the kidneys become damaged or gradually lose their ability to filter waste and excess fluid from the blood effectively. CKD is commonly associated with conditions such as diabetes and long-standing high blood pressure. Other causes can include inherited kidney disorders, autoimmune diseases, urinary obstruction and repeated or prolonged exposure to certain kidney-affecting medicines. Patients who want to understand CKD in more detail can explore Dr. Jyoti Bansode’s Acute & Chronic Kidney Diseases service page. Acute & Chronic Kidney Diseases Why Are the Early Signs of Chronic Kidney Disease Important? One of the biggest challenges with CKD is that the kidneys can compensate for reduced function for a long time. This means a patient can feel normal even when kidney damage has already started. Mayo Clinic notes that early chronic kidney disease often produces few or no noticeable symptoms. Symptoms tend to become clearer as kidney function declines. Finding CKD early gives doctors an opportunity to identify the cause, control contributing conditions and monitor kidney function before the disease becomes more advanced. What Early Kidney Disease Signs Do Patients Often Miss? 1. Unusual Tiredness Persistent fatigue or reduced energy can occur when kidney function becomes impaired. However, tiredness can have many causes, which is why it is often overlooked. 2. Foamy or Frothy Urine Persistently foamy urine can sometimes indicate protein leaking into the urine. Protein or albumin in the urine can be an important sign of kidney damage. 3. Swelling Around the Feet or Ankles Kidneys help regulate fluid and salt. When kidney function declines, excess fluid can contribute to swelling in the feet, ankles or sometimes around the eyes. 4. Changes in Urination Some patients notice that they urinate more frequently, especially at night. Others may notice changes in urine quantity, appearance or frequency. 5. High Blood Pressure High blood pressure can damage the kidneys, but kidney disease can also make blood pressure more difficult to control. Persistent or difficult-to-control hypertension therefore deserves attention. 6. Poor Appetite or Nausea Reduced appetite, nausea or an unusual taste in the mouth may occur as kidney disease becomes more advanced. 7. Dry or Itchy Skin Persistent itching can occur in more advanced kidney disease and may be related to changes in mineral balance and the buildup of substances normally cleared by healthy kidneys. 8. Muscle Cramps or Trouble Sleeping Muscle cramps and sleeping problems are also reported in people with worsening kidney disease, although these symptoms are not specific to CKD. What Are the Different Stages of Chronic Kidney Disease? CKD is generally categorized into stages based largely on estimated glomerular filtration rate (eGFR) together with evidence of kidney damage such as urine albumin. CKD Category eGFR General Meaning G1 90 or above Normal/high filtration with other evidence of kidney damage G2 60–89 Mildly reduced filtration with evidence of kidney damage G3a 45–59 Mild to moderate reduction G3b 30–44 Moderate to severe reduction G4 15–29 Severe reduction G5 Below 15 Kidney failure range The number should always be interpreted by a healthcare professional because one eGFR result alone does not necessarily establish CKD. What Are the Benefits of Detecting CKD Early? Early detection can help identify potentially treatable or controllable causes of kidney damage. For example, controlling diabetes and blood pressure, reviewing medicines and monitoring urine protein may help reduce additional stress on the kidneys. Diabetes is an important cause of chronic kidney disease. Patients with both diabetes and abnormal kidney tests can learn more about Diabetes & Kidney Diseases. Diabetes & Kidney Diseases How Is Early Chronic Kidney Disease Detected? Because symptoms are often absent, blood and urine tests are particularly important. Kidney evaluation may include serum creatinine, eGFR, urine routine examination and the urine albumin-to-creatinine ratio (UACR). NIDDK identifies eGFR and urine albumin as two key markers used when assessing chronic kidney disease. A UACR above 30 mg/g is considered abnormal and may indicate albuminuria. Doctors may repeat abnormal tests because kidney disease is generally evaluated using persistent findings rather than relying on a single result. Who Should Consider Regular Kidney Testing? kidney-function-testing-monitoring Regular kidney monitoring is particularly important for people with: – Diabetes – High blood pressure – Heart disease – Previous kidney problems – Family history of kidney failure – Abnormal creatinine or eGFR – Protein or blood detected in urine People with these risk factors may have kidney damage before noticeable symptoms appear. Risks and Important Considerations Symptoms such as tiredness, swelling or frequent urination do not automatically mean that someone has CKD. Many other conditions can produce similar symptoms. At the same time, patients should not ignore persistent symptoms or abnormal kidney reports. Avoid self-treatment with excessive water, herbal remedies or unverified “kidney detox” products. Kidney treatment should depend on the underlying cause and individual kidney function. What Factors Affect the Cost of CKD Evaluation? There is no single fixed cost for chronic kidney disease evaluation because different patients require different investigations. Costs may depend on the nephrology consultation, creatinine and eGFR testing, urine tests, UACR, blood pressure assessment, ultrasound or other investigations. Patients with established CKD may also need ongoing monitoring depending on the stage and underlying cause. Expert Insights: When Should You See a Nephrologist? Consider seeing a nephrologist if you have persistently

Your eGFR (estimated glomerular filtration rate) is one of the most useful numbers for understanding how well your kidneys are filtering waste from your blood. In general, a higher eGFR suggests better kidney filtration, while a persistently low eGFR may indicate reduced kidney function. However, one eGFR result alone does not diagnose chronic kidney disease. Doctors interpret eGFR together with creatinine, urine albumin or protein, previous reports, age, medical history and conditions such as diabetes or high blood pressure. Patients with repeatedly abnormal kidney-function reports can consult a nephrologist in Navi Mumbai for appropriate evaluation. What Is an eGFR Test? eGFR stands for estimated glomerular filtration rate. It estimates how much blood the kidneys filter over a period of time and is commonly reported as part of a kidney function blood test. The value is usually calculated using the amount of creatinine in your blood along with other relevant factors. Creatinine is a waste product generated from normal muscle activity. Because the kidneys remove creatinine from the bloodstream, changes in creatinine can influence the calculated eGFR. Why Is eGFR Important for Kidney Health? Kidney disease can develop without obvious symptoms, particularly during its earlier stages. An eGFR test can therefore help identify reduced kidney filtration even when a person feels well. The test is particularly important for people who have diabetes, hypertension, heart disease, abnormal creatinine or a known kidney condition. If kidney function remains abnormal, further evaluation for acute or chronic kidney disease may be required Does an eGFR Below 60 Mean Kidney Disease? Understanding Low eGFR When to Consult a Kidney Specialist An eGFR below 60 can indicate reduced kidney filtration, particularly when it remains below this level over repeated tests for three months or longer. Your doctor may review previous creatinine and eGFR results to determine whether the change is persistent or temporary. A temporary reduction may sometimes occur during acute illness, dehydration or other situations affecting kidney function. This is why doctors do not normally interpret one laboratory result without considering the patient’s overall clinical condition. Is an eGFR Above 60 Always Normal? Not necessarily. Someone can have an eGFR above 60 and still have signs of kidney damage, such as persistent albumin or protein in the urine. This is why kidney assessment often includes both eGFR and a urine albumin-to-creatinine ratio (UACR). A UACR above 30 mg/g may indicate albuminuria and requires interpretation by a healthcare professional. How Are Creatinine and eGFR Connected? Creatinine and eGFR are closely related. When kidney filtration decreases, creatinine may rise and the calculated eGFR may fall. However, serum creatinine can also be influenced by factors such as muscle mass, diet and certain clinical conditions. For this reason, eGFR generally provides more useful context than looking at creatinine alone, although neither number should be interpreted in isolation What Can Affect an eGFR Result? Several factors can influence the accuracy or interpretation of an eGFR result. These may include changes in creatinine, unusual muscle mass, recent illness, diet, pregnancy, some medicines and rapidly changing kidney function. Because eGFR is an estimate rather than a direct measurement, doctors may sometimes use additional tests when the result does not match the patient’s overall clinical picture. Cystatin C can also be used in some circumstances to improve estimation of GFR Why Are Diabetes and High Blood Pressure Important? Diabetes and high blood pressure are important causes and risk factors for chronic kidney disease. People with diabetes should have their kidney health monitored because kidney damage can develop gradually. Patients who have diabetes together with abnormal eGFR or urine protein can read more about diabetes and kidney disease. Similarly, persistent or difficult-to-control hypertension may require evaluation because blood pressure and kidney health are closely connected. What Should You Do If Your eGFR Is Low? Do not panic based on a single laboratory result. Your doctor may first compare the result with previous reports and may recommend repeating creatinine and eGFR. Further evaluation may include urine routine examination, UACR, blood pressure assessment, electrolytes, blood sugar testing and kidney imaging depending on the clinical situation. The goal is to understand why the eGFR is low, whether the change is temporary or persistent and whether kidney damage is present. Can a Low eGFR Improve? A reduced eGFR may improve when it is caused by a reversible problem such as dehydration or certain acute illnesses. However, chronic kidney disease usually requires long-term monitoring and management aimed at slowing further loss of kidney function. Patients should not attempt to increase eGFR through excessive water intake, supplements or unverified kidney-cleansing remedies. Treatment should address the underlying cause and be guided by the treating doctor or nephrologist. When Should You See a Nephrologist? Consider seeing a kidney specialist if your eGFR remains below normal on repeated tests, continues to decline, or occurs with high creatinine, protein or blood in urine, swelling, reduced urine output, diabetes or uncontrolled hypertension. A rapid decline in kidney function, very low urine output, severe breathing difficulty, confusion or significant swelling may need urgent medical evaluation rather than waiting for a routine appointment. eGFR Evaluation by a Nephrologist in Navi Mumbai and Vashi Patients with abnormal kidney function reports can learn more about Dr. Jyoti Bansode and her nephrology services.

Frequently Asked Questions What is a normal eGFR? An eGFR of 90 or above generally represents normal or high filtration in adults, although kidney health should also be assessed using urine tests and other clinical information.

A high creatinine level can happen when the kidneys are not filtering waste from the blood efficiently, but it does not always mean that a person has kidney failure. Dehydration, intense exercise, certain medicines, a high intake of cooked meat, infections and temporary changes in kidney function can also increase creatinine. If creatinine remains high, continues to rise or is associated with a low eGFR, abnormal urine tests, swelling or changes in urination, further kidney evaluation may be required. Patients looking for a nephrologist in Navi Mumbai can have their reports evaluated to determine whether the change is temporary or related to an underlying kidney condition. What Is Creatinine? Creatinine is a waste product produced naturally by normal muscle activity. It enters the bloodstream and is filtered by the kidneys before leaving the body through urine. Because the kidneys remove creatinine, a serum creatinine blood test is commonly used as part of kidney function evaluation. However, creatinine should not be interpreted alone. Doctors usually consider it together with eGFR, urine tests, age, muscle mass, medical history, current medicines and previous laboratory reports. Why Is High Creatinine Important? High creatinine can sometimes be an early indication that kidney filtration has decreased. Kidney problems may not always cause noticeable symptoms in the early stages, which is why abnormal blood or urine reports can be important. Doctors pay particular attention when creatinine rises suddenly, stays elevated over repeated tests or occurs together with protein in the urine, reduced eGFR, uncontrolled diabetes or high blood pressure. Patients can learn more about conditions that affect kidney function through the acute and chronic kidney disease service page. What Are the Common Causes of High Creatinine? There are several possible causes of high creatinine, and the reason can differ from one patient to another. Dehydration: Poor fluid intake, vomiting, diarrhoea, fever or significant fluid loss can reduce blood flow to the kidneys and may temporarily affect creatinine levels. Acute kidney injury: Kidney function can sometimes decline suddenly because of severe dehydration, infections, very low blood pressure, certain medicines or serious illness. Chronic kidney disease: Long-term kidney damage may gradually reduce the kidneys’ ability to filter waste, resulting in persistently abnormal creatinine levels. Diabetes: Long-standing or poorly controlled diabetes can damage the small blood vessels involved in kidney filtration. People with diabetes and abnormal kidney reports can read more about diabetes and kidney disease. High blood pressure: Persistent hypertension can damage kidney blood vessels over time. Kidney disease can also make blood pressure more difficult to control. Certain medicines: Some painkillers and other medicines can affect kidney function, particularly in patients who are dehydrated or already have kidney disease. Prescribed medicines should not be stopped without medical advice. Other possible factors include strenuous exercise, creatine supplements, large amounts of cooked meat, urinary blockage, kidney infection and some severe medical conditions. Quick Facts About High Creatinine Question Quick Answer Does high creatinine always mean kidney disease? No Can dehydration raise creatinine? Yes, in some situations Can exercise affect creatinine? Intense exercise may temporarily increase it Is creatinine alone enough to diagnose kidney disease? No What other tests may be needed? eGFR, urine albumin/protein tests and other investigations Should persistently rising creatinine be evaluated? Yes What Are the Benefits of Early Kidney Evaluation? Early assessment can help identify potentially reversible problems such as dehydration, infection, medication-related kidney injury or urinary obstruction before they become more serious. For people with diabetes, hypertension or an existing kidney condition, regular kidney monitoring can also help detect changes in kidney function over time. Early evaluation may allow treatment to focus on protecting remaining kidney function and controlling contributing conditions. How Is High Creatinine Evaluated? A nephrologist or kidney specialist generally reviews more than one creatinine value. Previous laboratory reports, blood pressure, diabetes history, medicines, supplements, fluid intake and current symptoms are also important. Depending on the individual situation, kidney evaluation may include repeat serum creatinine, eGFR, urine routine testing, urine albumin or protein assessment, electrolytes and kidney imaging when clinically necessary. The investigations required vary according to the patient’s symptoms and medical history. Can High Creatinine Be Reduced? There is no single medicine, food or home remedy that is suitable for every person with high creatinine. Treatment depends entirely on why the creatinine has increased. For example, dehydration may require appropriate fluid management, infection may need medical treatment, diabetes and hypertension require ongoing control, and medication-related kidney problems require professional review. Patients should avoid excessive water intake, extreme diets or unverified supplements solely to reduce a laboratory number. Risks and Important Considerations One common misconception is that drinking large amounts of water will automatically reduce high creatinine. This is not appropriate for every patient. Some people with kidney or heart conditions may require specific fluid recommendations. Similarly, do not stop blood pressure, diabetes or other prescription medicines just because a creatinine result is abnormal. Medicine changes should be discussed with the treating doctor or nephrologist. What Factors Affect the Cost of High Creatinine Evaluation? High creatinine is a laboratory finding rather than a single disease, so there is no standard treatment cost. The overall cost depends on the nephrology consultation, repeat blood tests, urine testing, kidney imaging and treatment required for the underlying cause. A patient with a temporary increase may need fewer investigations than someone with acute kidney injury or chronic kidney disease.
