Mr Anjan,
your fasting sugar is moderately high which puts you in pre-
diabetic or
diabetic range. When you say post-
lunch, how many hours had passed after
lunch when the sugar was checked ? I ask because I would have expected that number to be as high or higher than the fasting number. However, if the post lunch test was done after many hours with perhaps you being moderately active, then that would explain the relatively low number.
