Many parents believe kidney disease is a distant concern for their children, affecting only a small number of unlucky kids. However, specialists note that pediatric kidney disease is not as rare as we imagine. In fact, many parents may even be contributing to it! Older Children Who Still Wet the Bed Should Have Kidney Function Checked"Kidney disease now threatens not only adults but has become a serious health risk for children. The problem is, often when kidney issues arise, the guardians—the parents—remain completely unaware," says Dr. Bao Huaying, Chief Physician of the Nephrology Department at Nanjing Children's Hospital.
Take the simplest example: When a child continues bedwetting as they grow older, parents may feel anxious. But how many would consider that it might be time to have their child's kidneys checked?
"In fact, if a child over 5 years old experiences involuntary urination during sleep ≥2 times per week for over 6 months, it qualifies as pediatric enuresis.In such cases, it's essential to seek consultation with a nephrologist," Bao Huaqing explained. This is because enuresis can stem from numerous causes. Beyond genetic factors, it may involve issues across nephrology, endocrinology, urology, neurology, and psychology. Notably, many kidney and urinary system problems can trigger childhood enuresis. At this point, parents should consult a specialist.
Incorrect feeding practices may also harm kidneys
Additionally, many parents are unaware that seemingly harmless actions can pose significant threats to their child's kidneys.
For instance, pediatricians often advise against adding salt to a baby's food before age one. Ideally, low-salt, bland diets should be maintained until age three if possible.Yet some parents still fail to understand or follow this advice. They may not realize that introducing salt too early not only develops a preference for salty flavors, making babies reject plain foods, but also places a heavy burden on their kidneys!
Dr. Ding Guixia, Associate Chief Physician at the Nanjing Children's Hospital Nephrology Department, explains that infants under one year old require less than 1 gram of salt daily. Breast milk or formula alone provides sufficient sodium for this age group.Adding salt or high-sodium foods to their diet places substantial strain on their tiny kidneys. Over time, this may increase the risk of developing kidney disorders.
"In reality, numerous factors contribute to childhood kidney issues. Beyond genetic predispositions, many relate to lifestyle choices—diet, exercise, hygiene habits, and common infections. Parents often fail to recognize how these seemingly minor issues connect to kidney health," Dr. Ding explained. "This can lead to unnoticed kidney damage, with parents unaware—or even inadvertently worsening the situation."
