Meta Description: Learn about Blood Sugar (Fasting & PP), normal values, causes of high & low sugar, and how to maintain healthy glucose levels.
What is Blood Sugar (Fasting & PP)?
Blood sugar, also known as blood glucose, is the concentration of glucose in your blood. It comes from food and is the body’s main source of energy.
Fasting Blood Sugar (FBS): Measured after 8–10 hours of fasting, usually in the morning.
Postprandial Blood Sugar (PPBS): Measured 2 hours after eating a meal.
Both are essential for diagnosing and monitoring diabetes.
Why is Blood Sugar Testing Important?
Detects diabetes and prediabetes early.
Helps monitor treatment in diabetic patients.
Prevents long-term complications (heart, kidney, nerve, eye problems).
Guides doctors to adjust medicine, diet, and exercise.
Causes of High & Low Blood Sugar
🔴 High Blood Sugar (Hyperglycemia)
Diabetes (Type 1 & Type 2)
Eating too many carbs
Lack of physical activity
Stress or infection
Hormonal disorders
🔵 Low Blood Sugar (Hypoglycemia)
Overdose of insulin/medications
Skipping meals
Drinking too much alcohol
Prolonged fasting
Normal Blood Sugar Values
Test Type Normal Range Prediabetes Diabetes
Fasting Blood Sugar (FBS) 70 – 100 mg/dL 101 – 125 mg/dL ≥ 126 mg/dL
Postprandial Blood Sugar (PPBS) < 140 mg/dL 140 – 199 mg/dL ≥ 200 mg/dL
How to Maintain Healthy Blood Sugar?
✅ Eat a balanced diet (vegetables, whole grains, lean protein).
✅ Avoid refined sugar and processed carbs.
✅ Exercise at least 30 minutes daily.
✅ Manage stress and get enough sleep.
✅ Monitor sugar regularly if you have diabetes.
✅ Follow doctor’s advice for medicines or insulin.
Conclusion
Blood Sugar (Fasting & PP) tests are simple yet powerful tools for detecting and controlling diabetes. Knowing the normal values and adopting a healthy lifestyle can protect you from severe complications.
