what is glucose in blood test high

High glucose levels in a blood test, also known as hyperglycemia, indicate that there is too much sugar (glucose) in your bloodstream. This can be a sign of diabetes or prediabetes. Here are some key points:

• Normal Range: Fasting blood glucose levels should typically be between 70-99 mg/dL.
• Prediabetes: Fasting blood glucose levels between 100-125 mg/dL may indicate prediabetes.
• Diabetes: Fasting blood glucose levels of 126 mg/dL or higher on two separate tests usually indicate diabetes.

High glucose levels can result from:

• Insulin Resistance: Your body isn't using insulin effectively.
• Lack of Insulin: Your pancreas isn't producing enough insulin.
• Diet and Lifestyle: High carbohydrate intake, lack of exercise, and stress can contribute.

If your blood glucose levels are consistently high, it's important to consult with a healthcare provider for further evaluation and management.
