The second case is that the body can produce insulin, but because of present body condition, the body resists using it, hence because of which the blood glucose does not gets used. If you are urinating more number of time then usual, feeling more hunger or fatigue, then you should go to your doctor for a checkup as these are some common symptoms of type 2 diabetes.
I had also reduced my insulin dosage from 4 shots, 60 units of insulin (Humalog and Lantus) a day down to 1 shot, 10 units (only Lantus). By my next doctor’s appointment, I was down to zero shots and a zero insulin dosage. But, my endocrinologist was not happy and told me to return to my original insulin dosage. He said that since I was going through the “honeymoon period”, my blood sugar would eventually return to the high levels and I would have to go back on insulin.
