Takeout meals, sitting at a desk most of the day and an extra 20 pounds that you just can't shake — if that sounds like you, listen up. You're one of the millions of Americans at risk of developing metabolic syndrome, a cluster of health conditions that includes obesity, high blood pressure, type 2 diabetes and abnormal cholesterol.
"All of these conditions are related — if you're overweight, especially around your abdomen, that fat secretes hormones such as stress hormones that raise your blood pressure, blood glucose levels and levels of LDL ["bad"] cholesterol,” explains Dennis Bruemmer, a cardiologist at the Cleveland Clinic.
The relationship between heart disease and type 2 diabetes has become so interrelated now, that some experts in the field are even suggesting the creation of a new specialty: “cardiabetes.” “My patients are surprised to learn that all of these are so interconnected, but they are,” Bruemmer adds.
While around 1 in 3 Americans have metabolic syndrome, people over the age of 60 are particularly vulnerable, with about 1 in 2 affected, according to a 2015 study published in the Journal of the American Medical Association.
"It's become more common in people of all ages, including children, but older adults are especially at risk because they're also more prone to weight gain and developing chronic diseases such as hypertension as they age,” Bruemmer notes. But this condition, also known as insulin resistance syndrome, or Syndrome X, raises the risk of a whole host of conditions, including type 2 diabetes, heart attack and stroke.
Here's what you need to know.
Why it's so dangerous
To be diagnosed with metabolic syndrome, groups like the American Heart Association and the American College of Cardiology agree that you need to have at least three of the following five risk factors:
- A waist size greater than 40 inches in men, and 35 inches in women.
- Abnormal blood sugar levels. You don't have to have full-blown type 2 diabetes, but you may be in the prediabetes stage. That's a fasting blood sugar greater than or equal to 100 milligrams per deciliter (mg/dL), or a hemoglobin A1C level that's at least 5.7 percent.
- High blood pressure (anything above 130/85)
- Elevated triglycerides (greater than or equal to 150 mg/dL)
- Low HDL ("good") cholesterol, or less than 40 mg/dL for men or 50 mg/dL for women.
But even having just one or two of these risk factors is cause for concern. “About half of all patients that we diagnose with metabolic syndrome already have undiagnosed cardiovascular disease, such as changes in the walls of their blood vessels that haven't yet caused symptoms,” Bruemmer says. That's why staying on top of all of these conditions — and treating them aggressively — is key. Otherwise, people who go on to develop metabolic syndrome are at risk of several life-threatening conditions, including:
