As Malaysia grapples with rising obesity rates, experts are warning that the nation is facing an alarming increase in kidney failure cases linked to obesity-related chronic kidney disease (CKD).
In conjunction with World Kidney Day, which falls today, medical professionals are urging immediate action to combat the growing prevalence of CKD, which is heavily influenced by unhealthy dietary habits and sedentary lifestyles.
Prof. Dr. Wong Hin Seng, a consultant nephrologist and kidney transplant physician at Sunway Medical Centre, highlighted the serious risks of obesity on kidney health. He emphasized that even in the absence of diabetes or hypertension, obesity alone can lead to irreversible kidney damage.
According to the National Health and Morbidity Survey (NHMS) 2023, more than half of Malaysians (54.4%) are classified as overweight or obese. The survey also revealed that over two million people suffer from non-communicable diseases such as diabetes and hypertension. These conditions are major contributors to kidney failure, with the Malaysian Dialysis and Transplant Registry 2023 reporting that 56% of new dialysis cases are caused by diabetes, followed by hypertension at 30%.
Dr. Wong explained that obesity strains the kidneys by triggering chronic inflammation, oxidative stress, elevated blood pressure, and insulin resistance, all of which can lead to protein leakage in urine—an early indicator of kidney damage.
The dangers of kidney disease may go undetected for years, especially among younger individuals who may not exhibit obvious symptoms. The NHMS study further revealed that 84% of adults aged 18 to 24 are unaware that they have diabetes, a condition that significantly increases the risk of CKD.
“Obesity accelerates the progression of CKD. The constant strain on the kidneys from obesity can lead to faster deterioration of kidney function,” Dr. Wong warned. “For those who have been obese since childhood or adolescence, the damage to their kidneys may already be significant, potentially leading to CKD by their 30s or 40s.”
The surge in obesity rates in Malaysia is largely attributed to changes in dietary habits and lifestyle. Dr. Wong noted a shift away from traditional, healthier diets toward processed foods and sugary beverages, combined with a marked decline in physical activity. Children, once active and engaged in outdoor play, are now spending more time in front of screens, while adults lead increasingly sedentary lives, spending hours in front of computers or televisions.
Dr. Wong stressed the importance of early intervention in combating obesity and preventing kidney disease. He advised Malaysians to undergo regular health screenings, including kidney function and urine protein tests, to detect any early signs of kidney damage, particularly in those who are overweight or diabetic.
“By addressing obesity and prioritizing kidney health, Malaysians can build healthier, stronger futures,” Dr. Wong said. “Obesity is not just about weight—it’s about the toll it takes on our organs, especially the kidneys. Our kidneys work tirelessly, and it’s time we give them the care and attention they deserve.”
As the country faces an increasing burden of kidney-related diseases, experts stress the need for lifestyle changes, healthier eating habits, and more active lifestyles to protect the future of public health in Malaysia.
