Fasting Blood Sugar Levels

Fasting blood sugar is the level of glucose in your blood after not eating for at least eight hours, usually measured first thing in the morning. Interpreting fasting blood sugar levels can help detect conditions such as prediabetes or diabetes.

Prediabetes	100-125	Indicates a higher risk of developing diabetes. Lifestyle changes are recommended.
Diabetes	126 or higher	Consistent readings in this range may indicate diabetes. Consult a healthcare provider.

Blood Sugar Levels After Meals (Postprandial)

Postprandial blood sugar refers to your blood glucose levels measured after eating. It is usually checked one to two hours after starting a meal. This measurement is important as it shows how well your body is processing the carbohydrates you've consumed.

Category	1-2 Hours After Meal (mg/dL)	Interpretation
Normal	Less than 140	Indicates healthy glucose metabolism after eating.
Prediabetes	140-199	May indicate impaired glucose tolerance. Requires lifestyle interventions.
Diabetes	200 or higher	Suggests poor glucose control. Medical intervention may be necessary.
