Which conditions are included in the definition of "metabolic syndrome"?

Metabolic syndrome is defined by a collection of conditions that increase the risk of heart disease, stroke, and diabetes. The correct answer identifies high blood pressure and excess body fat as key components of this syndrome. High blood pressure contributes to the strain on the cardiovascular system, while excess body fat, particularly around the abdomen, is associated with an increased risk of insulin resistance and other metabolic issues. The presence of these conditions typically indicates metabolic dysfunction, making individuals more susceptible to serious health complications.

In contrast, the other options mention conditions that do not correlate with metabolic syndrome. Low cholesterol and high energy levels do not indicate metabolic dysfunction. Similarly, poor vision and high calcium levels or low blood sugar and lack of appetite do not relate to the key indicators of metabolic syndrome. Understanding the relationship between these specific health conditions and metabolic syndrome is crucial for recognizing and managing the risks associated with it.
