Dear Doctor .I need an advice regarding my sugar management as below -- I was noticed with PP sugar of 206 in Jan 2014 and fasting at 120. My HBa1c parameter was at 6.5. I was given Sugamet MC for almost nine months and testing was done every three months. Now -- 1.With sugamet MC 500 once a day my HBa1c is 5.6 and also the fasting sugar and PP sugar is with in normal book limits. 2.I stopped sugamet mc 500 3 months back. Now my parameters are as below -- HBa1c parameter is 6.0. Fasting sugar is 111 and PP sugar is 160 My question is --- 1.When I am in normal limits (ofcourse its near the upper limit) without medicine. Should I still take the medicine? 2.Is taking metformin preventive in nature? I mean taking Sugamet mc 500 still will prevent my sugar metabolism from worsening further? I am a regular exerciser. I spend one hour in a gym doing muscle and weight training exercises. Alternate days I go for fast walk for 2kms with stretching exercises. Its my regular routine. Pls advise if I shd continue with medicine or not. Regards
