Hello,, I went through your query, there are two tests done to know the suger levels in body,, one is fasting blood suger and another Is postprandial blood suger(ppbs) . (2hrs after food), if your fasting blood suger Is, 160-170, even after excersie and diet then you need to take medicines, if it is ppbs, which is 160-170,then no beer to worry,, do cycling for 20min in the evening along with regular exercise, avoid sweets and rice,, it will come well under control. And
hba1c, shows
sugar control form past 3 or 4months,, so if fbs and ppbs are under control then don't worry.
