Question

Observe the given blood test result of a person and answer the following questions:

(a) Is the fasting blood glucose value normal?
(b) Is the given HbA1c value normal? Why?
(c) Suggest any two lifestyle habits that people should follow to maintain a normal blood glucose level.

Hint:

Remember: Normal FBS = 70–100 mg/dL, Normal HbA1c <5.7%. Higher HbA1c indicates long-term high blood sugar levels.

Answer 1

Step 1: Analyse fasting blood glucose (FBS).
The normal fasting blood glucose level lies between 70–100 mg/dL. The given value is 90 mg/dL, which falls within the normal range.
Step 2: Answer part (a).
Yes, the fasting blood glucose value is normal.
Step 3: Analyse HbA1c value.
HbA1c represents the average blood glucose level over the past 2–3 months. A normal HbA1c value is usually below 5.7%. Values between 5.7%–6.4% indicate prediabetes, and values 6.5% or above indicate diabetes. The given value is 6.7%.
Step 4: Answer part (b).
No, the HbA1c value is not normal because it is above 6.5%, indicating diabetic condition.
Step 5: Suggest lifestyle habits.
To maintain normal blood glucose levels, the following habits should be followed:
- Regular physical exercise
- Balanced diet with low sugar and controlled carbohydrate intake
Step 6: Answer part (c).
Two lifestyle habits are regular exercise and healthy balanced diet.
