Is FB and PP a realistic check of blood sugar than a one time Hba1C

Ans: HbA1c provides a long-term view. It measures average blood glucose levels over the past 2 to 3 months and used to diagnose diabetes and monitor long-term glucose control. While FB and PP measurements offer insights into immediate fluctuations. FB levels are sensitive to immediate changes (e.g., stress, illness) and PP is useful for understanding how specific foods affect blood sugar. Combining these tests provides a comprehensive picture of blood sugar control.

Pre and post sugar levels do not matter all we need to keep H1BAC below 7 is true

Ans: Not true. Glucose levels throughout the day matter. A combination of high and low glucose levels on some days will still give a good HbA1c. We need to avoid both highs and lows. “Time in range” is the latest concept and you need a CGM (continuous glucose monitor) device to estimate that.

Hi , My Hba1c is 6.5-6.6 but sugar fasting is 100-110 and PP is varying 120-145 . These results are in same range since 2years .what does it means ? what should be the diet plan ? how to reduce Hba1c ? whether i am a diabetic ?pl suggest

Ans: A normal level for an HbA1c is below 5.7%.. Your level is indicative of diabetes. Normal fasting blood sugar is less than 100 mg/dl and your range of 100-110 mg/dl which suggests prediabetes. Focus on a balanced diet rich in whole grains, lean proteins, healthy fats, and plenty of vegetables. Limit refined sugars, processed foods, and high-calorie snacks. Monitor portion sizes and spread meals throughout the day. Regular exercise helps lower blood sugar levels. Discuss your results with a registered dietician or your family physician.

Is HbA1c 12.5 & fasting 270 with PP 303 very high sugar??

Ans: Yes. An HbA1c of 12.5% and fasting blood sugar of 270 mg/dl indicate poor blood sugar control. Similarly, a postprandial (after-meal) blood sugar level of 303 mg/dl is also high. It’s essential to consult with your family doctor to manage and address these elevated levels promptly.

Dear Sir I am diabetic. Since last 2 yrs my doctor is advising for PP and hba1c tests after 1.5 hrs instead of 2 hours of taking food. All reputed Labs also following the same time period. Then what should be the ideal pp and hba1c value in that conditions for a diabetic. Regards

Ans: Not sure why you are being advised pp after 90 min.
The timing of pp is two hours after the first bite of breakfast.

A good control mean, PP in range of 70 to 180 mg%. However, more around 100 to 140 mg%. The HbA1c should be below 7% Specially those whoa re above 65 years of age and preferably below 6.5% for a tighter control if person is younger than 65 years.

These days, more individualised approach is followed for these parameters for effective control.
