Metabolic syndrome is a group of health problems that include too much fat around the waist, elevated blood pressure, high triglycerides, elevated blood sugar, and low HDL cholesterol.
Together, this group of health problems increases your risk of heart attack, stroke, and diabetes.
Metabolic syndrome is caused by an unhealthy lifestyle that includes eating too many calories, being inactive, and gaining weight, particularly around your waist. This lifestyle can lead to insulin resistance, a condition in which the body is unable to respond normally to insulin. If you have insulin resistance, your body cannot use insulin properly, and your blood sugar will begin to rise. Over time, this can lead to type 2 diabetes.
This syndrome raises your risk for coronary artery disease (CAD), even beyond that caused by high LDL cholesterol alone.footnote 1 It also increases your risk for diabetes.
The things that make you more likely to develop metabolic syndrome include:footnote 1
Your doctor can diagnose metabolic syndrome with a physical exam, your medical history, and some simple blood tests.
You may be diagnosed with metabolic syndrome if you have three or more of the risk factors listed in the table below. Note: These criteria were developed by the National Heart, Lung, and Blood Institute. Other organizations may have different criteria for diagnosis.
Abdominal obesity (waist measurement)
Men: 40 in. (102 cm) or more
Women: 35 in. (88 cm) or more
150 mg/dL or higher, or taking medicine for high triglycerides
High-density lipoprotein (HDL) cholesterol
Men: Less than 40 mg/dL
Women: Less than 50 mg/dL
Or taking medicine for low HDL cholesterol
130/85 mm Hg or higher, or taking medicine for high blood pressure
Fasting blood sugar
100 mg/dL or higher, or taking medicine for high blood sugar
The main goal of treatment is to reduce your risk of coronary artery disease (CAD) and diabetes. The first approaches in treating metabolic syndrome are:
