Kidney stones, a painful and often recurring condition, are largely influenced by one’s lifestyle and dietary habits, according to Dr. Kwok Jia Lun, Consultant and Head of Endourology at Tan Tock Seng Hospital (TTSH).
Speaking to Berita Harian, Dr. Kwok explained that men are more likely to develop kidney stones than women, though there is no clear evidence showing that any specific ethnic group—such as Malays—has a higher risk. The primary culprits remain dehydration, high salt intake, diets rich in animal protein, and a lack of physical activity.
Why Certain Jobs Are More at Risk
Drivers and delivery workers are particularly vulnerable because their jobs often limit access to toilets or drinking water. Prolonged dehydration can lead to more concentrated urine, which allows minerals to crystallize and form stones.
Hydration Is Key
Dr. Kwok stressed that drinking enough water is the most important step in preventing kidney stones. Singapore’s hot and humid climate causes people to sweat more, increasing the risk of dehydration. Regular water intake helps to flush out excess salts and minerals before they can solidify into stones.
Prevention Through Lifestyle
He advised the public to limit salt, red meat, and high-protein foods, and to increase consumption of fruits and vegetables. Regular exercise, maintaining a healthy weight, and balanced nutrition all help reduce the likelihood of stone formation.
Recognizing the Early Signs
Common symptoms include sharp pain in the side or lower back, blood in urine, nausea, and vomiting. Dr. Kwok urged anyone who experiences such pain to seek medical attention early. Diagnostic tests like ultrasound or CT scans can detect stones accurately, and early treatment prevents complications.
Treatment and New Technology
Singapore hospitals now offer minimally invasive treatments such as ureteroscopy and laser lithotripsy, which can remove or break stones without major surgery. New technologies also allow for early detection, improving patient outcomes.
Key Takeaway
While some factors like genetics may play a minor role, most kidney stones are preventable through better hydration and diet. As Dr. Kwok noted, “Lifestyle choices remain the biggest factor — and prevention is always better than cure.”
