I am 65, 45 days back, during annual checkup found my blood sugar 291 fasting and 391 PP. I consulted three doctors- including one expert in diabetics. All told me to start metformin. I did not start the medicine, bu started taking bitter guard+cucumber juice and ladies finger juice in the morning. I totally stopped rice and eat whole wheat bread, wheat porridge and vegetables. After the first 15 days my sugar (serum) came down to 126 fasting and 153 PP. Now after 45 days, of dieting and excecise my glucose (whole blood) has come down to107 fasting and 131 pp Is it safe to continue without medicine?
