Metabolic syndrome is a group of risk factors that raises your risk for heart disease and other health problems, such as diabetes and stroke. These risk factors can increase your risk for health problems even if they're only moderately raised (borderline-high risk factors).
Most of the metabolic risk factors have no signs or symptoms, although a large waistline is a visible sign.
Some people may have symptoms of high blood sugar if diabetes—especially type 2 diabetes—is present. Symptoms of high blood sugar often include increased thirst; increased urination, especially at night; fatigue (tiredness); and blurred vision.
High blood pressure usually has no signs or symptoms. However, some people in the early stages of high blood pressure may have dull headaches, dizzy spells, or more nosebleeds than usual.
