PPBS Levels More Than FBS. Previously Opposite. HBA1C 4.9. Reason, Treatment?

Blood sugar values pp more than fasting . Why is it so. What should I do? Why my fasting sugar value is rising.? My PP is always more than fasting values of blood sugar. I am 42 year old male weighing 61 kg with height at 155 cm. My blood sugar pp comes lower than the fasting. It has happens thrice and once it is equal. My father was diabetic. The latest values are 95 mg/dl (fasting) and 81 mg/dl (pp) An year before it were 90 mg/dl (fasting) and 78 mg/dl (pp). Three years back it was 91 fasting and pp. Eight years back it was 87 (fasting) and 70 (pp) I got it done from other lab and it was 98 (fasting) and 125 (pp) two years back. Hb1Ac is 4.9. It was same one year back. My queries and concerns are Why PP is more than fasting. and why fasting is in the higher range of normal values and rising every time. What can be done.

Hi there.

It is common in many people to have higher fasting sugar level than the PP sugars due to higher liver output of glucose during the overnight fast.
In your case you are totally safe as far as diagnosis of diabetes is concerned. Yearly or two yearly check up of sugars with HbA1c is more than enough for you to keep a watch.
In case you put on weight or become very sedentary in lifestyle or if any stress bothers you then in future there is a chance of having higher fasting sugar levels compared to your PP sugars as it is a sign of more insulin resistance in people genetically prone to have diabetes.
Hence take care of your general health and use preventive measures to avoid diabetes in you. Take care.
