Metabolic syndrome is a group of conditions that occur together, increasing the risk of heart disease, stroke, and type 2 diabetes. Obesity plus a sedentary lifestyle along the increasing age contributes to risk factors for metabolic syndrome, such as: large waistline, high blood pressure, high blood sugar levels, abnormal cholesterol or triglyceride levels, and excess body fat around the waist. Most of the disorders associated with metabolic syndrome do not have obvious signs or symptoms and are getting worse over time.
