Experts sound alarm over threat nearly 90% of adults will likely suffer from: 'A snapshot into our future'

Close to nine in 10 American adults are living with some degree of cardiovascular-kidney-metabolic syndrome, a condition that quietly damages the heart, kidneys, and metabolism all at once, reported the New York Post.

What's happening?

The American Heart Association devoted an entire chapter to CKM syndrome in its 2026 annual update, a first that signals how pervasive this health issue has become.

The condition occurs when issues with the heart, kidneys, blood sugar, and weight feed into one another. When one system falters, it drags the others down, too.

The data is especially troubling for younger generations: Over eight in 10 adults under 50 already display red flags for the syndrome.

"These numbers should ring alarm bells, particularly among young adults, because that's a snapshot into our future," said Dr. Sadiya S. Khan, a Northwestern University cardiologist and one of the report's lead authors, per the Post.

Why is CKM syndrome concerning?

When your heart, kidneys, and metabolism aren't working well together, the risk of heart attacks, strokes, and dying young goes up.

Air quality factors in here, too. Research has linked long-term exposure to polluted air with higher rates of heart disease, and those effects compound when someone already has metabolic or kidney problems.

For everyday people, this means paying attention to multiple health markers at once, not just one number at a doctor's visit. Blood pressure, blood sugar, cholesterol, and kidney function are connected, and letting one slip can pull the others off track.

The AHA report noted that hypertension and diabetes numbers have ticked upward in recent years, while obesity among kids has also climbed. These trends suggest the problem will only grow without intervention.

What can I do about CKM syndrome?

The good news is that the same habits that protect your heart also support your kidneys and metabolism.

The AHA's Life's Essential 8 guidelines offer a framework: focus on eating nutritious foods, staying physically active, avoiding tobacco, and getting enough sleep. Keeping tabs on your weight, cholesterol, blood sugar, and blood pressure matters, too.

If you live in an area with poor air quality, check your local daily pollution forecasts. Limit outdoor exercise on high-pollution days to reduce the strain on your cardiovascular system. Ask your doctor what markers you should watch, and build habits that protect all three systems at once.
