Metabolic syndrome is actually a cluster of medical conditions such as abdominal obesity, high blood pressure, high blood sugar and high cholesterol, which are associated with higher risk of developing cardiovascular disease and type 2 diabetes. It is estimated that 25% of American adults have metabolic syndrome. Although metabolic syndrome cannot be cured, it can be treated and mitigated with lifestyle changes such as exercise, quitting smoking, losing weight and eating a healthier diet.
