What fasting blood glucose level indicates a potential risk for metabolic syndrome?

1. Less than 100 mg/dL

2. 100 to 110 mg/dL

3. Greater than or equal to 110 mg/dL

4. Greater than or equal to 120 mg/dL

The correct answer is: Greater than or equal to 110 mg/dL

A fasting blood glucose level of greater than or equal to 110 mg/dL is significant as it indicates an elevated risk for developing metabolic syndrome. Metabolic syndrome is characterized by a cluster of conditions, including increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels. Monitoring fasting blood glucose levels is crucial because higher levels can indicate insulin resistance, a key feature of metabolic syndrome. The threshold of 110 mg/dL marks a critical point where intervention and lifestyle changes may be necessary to prevent progression to more serious conditions, such as type 2 diabetes and cardiovascular disease. The ranges below this threshold suggest a lower risk; thus, values of less than 100 mg/dL are generally considered normal, while those between 100 and 110 mg/dL are looked upon as prediabetic. Maintaining blood glucose levels below this critical point is vital for overall metabolic health.
