We are living in an era of ever increasing advances — Doctors have long known that there is a link between being overweight and a variety of health issues. Now, updated guidance from the American Heart Association (AHA) confirms obesity as a central driver of cardiovascular-kidney-metabolic (CKM) syndrome, rather than “an isolated risk factor.”
CKM syndrome is a complex health disorder linking cardiovascular disease, chronic kidney disease, and metabolic disorders such as type 2 diabetes and obesity. The AHA officially defined CKM syndrome in 2023 to address the interconnected nature of these conditions.
Evidence suggests that nearly 9 in 10 adults in the United States have at least one component of CKM syndrome. This includes risk factors such as high blood pressure, irregular cholesterol levels, high blood glucose, reduced kidney function, and excess weight.
Many of these factors often coexist and contribute to progressive damage across multiple organ systems. CKM syndrome develops along a continuum, beginning with metabolic risk factors and potentially advancing to significant cardiovascular and kidney disease if left unmanaged.
Now, the first-ever clinical guideline on CKM syndrome from the AHA and the American College of Cardiology (ACC), published in the journal Circulation, highlights the role of excess weight, positioning it as a key driver of CKM syndrome rather than simply a risk factor.
Despite highlighting obesity as a key driver, the guideline notes that body weight alone does not tell the whole story. Individuals may have the same body weight, but markedly different health profiles depending on how fat tissue affects metabolic function.
The document highlights abdominal fat, specifically visceral fat, as a particularly important contributor to disease progression.
Excess fat surrounding organs can promote chronic inflammation, insulin resistance, and damage to blood vessels, increasing the likelihood of developing diabetes, kidney disease, heart failure, heart attack, and stroke.
Other key takeaways from the new guidelines include:
- The new guidelines emphasize early identification and intervention, encouraging healthcare professionals to discuss weight management before serious complications develop.
- Specifically, the guidelines highlight the importance of metabolic health and abdominal fat, which can contribute to inflammation, insulin resistance, and damage to the heart, kidneys, and blood vessels.
- Recommended treatment should be comprehensive and coordinated, combining lifestyle changes and medications when appropriate, while improving collaboration among healthcare specialties.
The guideline also highlights healthy lifestyle practices as the foundation of CKM syndrome management. In particular, it advises incorporating the AHA’s “Life’s Essential 8 framework.” These are 8 modifiable factors that can help to reduce the risk of heart disease and improve overall health. The 8 metrics include regular physical activity, heart-healthy eating patterns, avoiding nicotine exposure, healthy sleep habits, and maintaining a healthy weight, blood glucose, blood lipids, and blood pressure levels.
