A growing body of evidence suggests that excess body weight is a major factor driving the development of cardiovascular-kidney-metabolic (CKM) syndrome, a condition that links obesity, diabetes, kidney disease, and cardiovascular disease through shared biological pathways. The findings, published in the journal Circulation, emphasise the importance of addressing excess weight early to reduce the risk of serious health complications affecting multiple organs.
According to researchers, CKM syndrome is a systemic disorder in which metabolic risk factors, chronic kidney disease, and cardiovascular disease interact and reinforce one another, ultimately leading to multi-organ dysfunction and a significantly higher risk of heart attacks, strokes, and premature death.
The study highlights that excess body weight, particularly abdominal obesity, often serves as the starting point for a chain reaction of health problems. Excess weight can contribute to insulin resistance, elevated blood pressure, unhealthy cholesterol levels, and inflammation, all of which increase the likelihood of developing diabetes, kidney disease, and cardiovascular conditions.
Commenting on the growing recognition of CKM syndrome, Dr. Kartikeya Kohli, Senior Consultant Internal Medicine Diabetes, Obesity and Kidney Diseases specialist, said, "CKM is one disease, many organs. The heart, kidneys, and metabolism work as one system; when one suffers, the others often follow. Treating one condition early helps protect the entire body.”
The American Heart Association defines Cardiovascular-Kidney-Metabolic Syndrome as a systemic disorder characterised by pathophysiological interactions among metabolic risk factors, chronic kidney disease, and the cardiovascular system, leading to multi-organ dysfunction and a high burden of cardiovascular disease.
Explaining the relationship between these conditions, Dr. Kohli noted that heart disease, kidney disease, diabetes, and obesity should not be viewed as isolated health problems.
“Heart disease, kidney disease, diabetes, and obesity are closely interconnected and often worsen one another. Obesity can lead to insulin resistance, diabetes, high blood pressure, and abnormal cholesterol levels. Diabetes damages blood vessels in the heart and kidneys, increasing the risk of cardiovascular disease and chronic kidney disease,” he explained.
He further added that impaired kidney function can raise blood pressure and place additional stress on the heart, while heart disease may reduce blood flow to the kidneys, accelerating kidney damage.
“Because these conditions share common risk factors and biological pathways, they are increasingly viewed as part of a single Cardiovascular-Kidney-Metabolic (CKM) syndrome,” Dr. Kohli said.
Researchers say this integrated approach represents a shift in how healthcare professionals understand and manage chronic diseases. Rather than treating obesity, diabetes, kidney disease, and heart disease separately, experts are encouraging a more comprehensive strategy focused on preventing and addressing the root causes that connect them.
The study also underscores the importance of routine screening for metabolic and cardiovascular risk factors, particularly in people who are overweight or obese. Early identification of elevated blood sugar levels, high blood pressure, declining kidney function, and abnormal cholesterol can help prevent progression to more severe disease stages.
In simple terms, CKM syndrome helps people understand how one health problem can trigger another. As Dr. Kohli explained, "CKM syndrome is a term doctors use to describe how obesity, diabetes, kidney disease, and heart disease are all deeply connected.”
“Instead of being separate problems, they feed into one another: extra weight can lead to diabetes, diabetes damages the kidneys, and kidney trouble forces the heart to work harder, dramatically raising the risk of a heart attack or stroke,” he said.
“In short, it’s a way of looking at health that says: if you treat one of these conditions early, you help protect the rest of your body.”
The findings reinforce the message that maintaining a healthy weight, staying physically active, eating a balanced diet, and managing risk factors early can play a crucial role in preventing CKM syndrome and protecting long-term heart, kidney, and metabolic health.
