When we think of kidney disease, we often picture an older adult battling high blood pressure or diabetes. But what if the real danger is actually lurking in children? Have we misunderstood the signs? Are the kids issues undetected? Pediatric kidney disease are rarely talked about, yet they can have lifelong consequences. Unlike adults, who have clear signs, children often exhibit symptoms so subtle that even the most attentive parents and doctors could miss it. Dr Narendra Shetty, Chief Wellness Officer at Kshemavana emphasizes, "Kidney diseases in children often go unnoticed because their symptoms mimic common childhood conditions. Early detection is key to preventing long-term complications."The Silent SymptomsA child who frequently wets the bed or seems tired throughout the day could very easily be dismissed by calling him "lazy" or saying that he is just "going through a phase". But what if that bedwetting is a sign of an underlying kidney disorder? What if their fatigue signals something far more serious than just a lack of sleep?Adults show obvious symptoms like swelling, high blood pressure, or reduced urine output. However, for children, it may be easier to overlook. Poor appetite, developmental delays, and general fatigue are often attributed to other childhood conditions or simply brushed off as normal. And for infants and toddlers—who cannot verbally express their discomfort—signs like excessive crying, restlessness, or irritability are often misunderstood, delaying crucial diagnoses.Dr. Shetty explains, "Children may not always communicate their discomfort effectively, making it crucial for parents and pediatricians to stay vigilant for subtle signs of kidney dysfunction."The concern is that the symptoms kids go through, often falls under the same category of common childhood infections. A child suffering from frequent urinary tract infection (UTI), could actually be vesicoureteral reflux (VUR), a condition where urine flows backward from the bladder to the kidneys, potentially causing long-term damage. However, because UTIs are more common in children, the actual condition may go undetected. Routine kidney function tests (RFTs) are rarely conducted in children unless there’s a specific reason. This lack of screening means many kidney issues remain hidden until the disease has progressed significantly, making treatment more complex and the impact more severe.Why Pediatric Kidney Diseases Are Different?In adults, kidney diseases are more often than note linked to lifestyle choices. However, in pediatric conditions, they are congenital or genetic. Some of the children are born with structural abnormalities that impair kidney function from the start. These conditions, if left undiagnosed can stunt physical growth. They could also delay developmental milestones and lead to long-term health complications. Children’s kidney diseases also tend to progress differently. They may remain silent for years, only surfacing when the damage is irreversible. In contrast, adult kidney disease usually progresses slowly, with symptoms appearing over time due to factors like hypertension or diabetes.Is Kidney Health Only About Drinking Water?If you think like this, then you may need to think again. Maintaining a healthy kidney is more than just drinking water. It has a lot to do in what you eat and what don't you eat. A high-sodium diet can raise blood pressure, putting unnecessary stress on the kidneys. Processed foods loaded with sugar and preservatives are equally harmful. Encouraging home-cooked meals over packaged snacks can go a long way in protecting children’s kidney health.Hydration plays a key role in maintaining kidney function. While dehydration can cause kidney stones and urinary tract infections, excessive fluid intake in children with conditions like nephrotic syndrome can lead to swelling and other complications.But diet alone isn’t the only villain. Environmental factors—such as exposure to heavy metals in contaminated water, pesticide-laden foods, air pollution, and overuse of certain medications—can silently damage the kidneys over time. Long-term exposure to toxins like arsenic, lead, and mercury can cause severe renal impairments, yet many parents remain unaware of these hidden dangers.Dr. Shetty warns, "Children are more vulnerable to environmental toxins than adults. Clean water, organic foods, and limiting unnecessary medications can go a long way in safeguarding their kidney health."Chronic Kidney DiseaseIn children with chronic kidney disease or CKD, dialysis and kidney transplants have long been the option. However, science could do more. One breakthrough in pediatric kidney care is the recombinant growth hormone (rGH) therapy which helps improve growth in children with CKD who suffer from malnutrition and stunted development. Emerging treatments such as stem cell therapy and regenerative medicine are also showing promise. Scientists are working on lab-grown kidney tissues that could one day replace damaged kidneys, offering new hope to children who would otherwise require transplants.A more holistic approach is also gaining traction. Dietary changes, including a low-protein, alkaline-based diet supplemented with omega-3 fatty acids, can slow kidney disease progression. Alternative therapies such as acupuncture, herbal treatments, and even specific yoga poses are being explored to complement traditional medical treatments.
