Thanks for the query.
RBG of 160 mg is high. It points out that there is a problem. But to decide whether one has diabetes
or not can only be decided by doing - Fasting, PP and HbA1c%. So please get these tests and then only a correct advise can be given. To confirm diabetes - FBG has to be 126 mg and above, PP 200 mg and above & HbA1c% 6.5 and above. So my suggestion is please get these tests at the earliest and come back with details. Thanks.
