Swelling in the feet and ankles is often dismissed as a sign of standing for too long, or perhaps a little weight gain. But increasingly, medical professionals are urging people not to ignore this symptom, as it could be an early indicator of kidney disease. The kidneys, vital organs responsible for filtering waste and excess fluid from the blood, play a crucial role in overall health. Recognizing the subtle early signs of kidney problems, like unexplained swelling, is key to timely diagnosis and treatment.
Chronic kidney disease (CKD) affects approximately 10% of the global population, according to the National Kidney Foundation . Yet, many people remain unaware of the condition in its early stages. Dr. Hemant Chaugule, a consultant nephrologist at Holy Family Hospital in Mumbai, emphasizes that symptoms don’t always appear only when the disease is advanced. “The body often gives subtle early warning signs. We just need to pay attention,” he says.
Understanding these early warning signs is crucial, as early intervention can significantly sluggish the progression of kidney disease and improve quality of life. Beyond swelling, several other changes can signal a problem with kidney function. Here’s a closer look at five key indicators to watch for, as identified by Dr. Chaugule.
Changes in Urination Patterns
One of the most noticeable early signs of kidney disease is a change in your usual urination habits. These patterns are generally consistent, so any deviation warrants attention. Dr. Chaugule explains that these changes can manifest in several ways. “First warning sign and you may find yourself passing urine more frequently,” he noted. “Some patients tell me their urine looks foamy or bubbly, which can indicate protein leakage. Some people say they feel like they are passing less urine. Some people say they feel like they are passing more urine in night (nocturia), passing blood in urine (hematuria).”
Foamy or bubbly urine is a particularly significant sign, as it suggests the presence of protein, which the kidneys should normally retain in the bloodstream. Increased frequency, reduced output, or blood in the urine are all reasons to consult a doctor promptly.
Swelling in the Feet, Ankles, or Around the Eyes
As mentioned earlier, swelling, or puffiness, in the feet, ankles, or around the eyes is a common early symptom. This occurs because the kidneys aren’t effectively filtering fluid, leading to a buildup of salt and water in the body. Dr. Chaugule points out that it’s easy to mistake this swelling for weight gain, but the key difference is that swelling tends to be localized and fluctuate, rather than being evenly distributed throughout the body.
Unremitting Fatigue and Weakness
Persistent fatigue and weakness, even after adequate rest, can also be an early sign of kidney problems. This is often linked to anemia, a condition where the body doesn’t have enough red blood cells. “A hormone produced by the kidneys regulates red blood cell production,” Dr. Chaugule explains. “If kidney function is impaired, the body becomes anemic. Weakness, breathlessness and fatigue may suggest anemia.”
Loss of Appetite, Nausea, or a Metallic Taste
Changes in appetite, accompanied by nausea or a metallic taste in the mouth, can also signal early kidney damage. These symptoms are often overlooked, but they can be indicative of a buildup of waste products in the blood, a hallmark of declining kidney function. It’s important not to dismiss these symptoms as simply a lack of hunger or a minor digestive issue.
Hypertension Challenging to Control
High blood pressure is a well-known risk factor for kidney disease, but Dr. Chaugule highlights an important connection: if hypertension remains difficult to control even with medication, particularly in younger individuals, it could be a sign of underlying kidney issues. The kidneys play a vital role in regulating blood pressure, and impaired kidney function can contribute to hypertension that is resistant to treatment.
Dr. Chaugule recommends that individuals with diabetes, hypertension, or a family history of kidney disease undergo regular blood and urine tests, rather than waiting for severe symptoms to develop. Early detection is paramount in managing and potentially slowing the progression of kidney disease.

As awareness of kidney health grows, proactive monitoring and attention to these early warning signs can empower individuals to accept control of their health and seek timely medical attention. The National Kidney Foundation continues to advocate for increased research and early detection initiatives to combat the rising prevalence of chronic kidney disease. If you are experiencing any of these symptoms, or have risk factors for kidney disease, schedule an appointment with your healthcare provider for evaluation.
