Respected doctors, my dad took a blood sugar test on 25th July in the afternoon after having lunch. It showed his blood sugar level as 289. To confirm, we took the blood test the next day, 26th July, which showed a completely different sugar level of 125 fasting and 153 after breakfast. After seeing both reports, the diabetologist advised my dad to exercise and walk more. Which sugar level is accurate? The first one taken after lunch or the second report taken in the morning, fasting and after food? Currently, he has not been prescribed any medicines and is taking the morning reading as the accurate one.

The first sugar test (289) after lunch is not reliable it varies based on meal. Fasting (125) and post breakfast (153) are more accurate and indicate prediabetes. Lifestyle changes are correct. Repeat HbA1c to get average 3 month sugar status. No meds needed if lifestyle is maintained.

My mother is 53 years old and has diabetes. Her recent blood report shows, serum creatinine is 1.0 mg/dL, blood urea is 33 mg/dL, cholesterol is 144 mg/dL, fasting blood sugar is 104 mg/dL, and post meal blood sugar is 177 mg/dL. Are these results concerning, and what should be the next steps for her care?

How fast can one change the HbA1c result?

Answered by Apollo Doctors

My father does not have diabetes. However, today his fasting glucose was 121 mg/dL, and his postprandial blood sugar (PPBS) was 88 mg/dL. Is this a concern? Why is the PPBS lower than the fasting glucose? How should we proceed? His HbA1c is 6.2 percent
