I am 60 years old male. I am suffering wit diabetics. My FBS & PPBS were 140 &165 respectively. After using an aurvedic medicine for the last four months Blood Gluckose level has come down to FBS 112 & PPBS 118. Now it is observed that my latest FBS 124 & PPBS116. For the last few test it is noticed that the FBS is more than PPBS. Why it is sow ?
