Hi Dr, age 57, recently my Dr did a blood glucose test on me in our general hospital, FPG result 5.7 and 2 hrs later OGTT result 3.7. Well he claim that I vomited, which was not the case neither did drink any water during the 2 hrs. Then send me for second test, 2 weeks later, again FPG 5.6 and OGTT 3.2. He is puzzled and cannot give any answer , just brushing off the question by saying at least we know you are not diabetic. My question is, why my glucose level drop so much after consuming the glucose? And am I diabetic? Thank you.
