<s>[INST] Last year on my physical ,my blood sugar level was 5. months after that I had a terrifying experience were I couldn t stop shaking for about 45 mins to an hour afterwards. This year s physical my blood sugar level was 6.2 fasting and 7.1 after glucose tolerance test. According to my doctor a have diabetes. Is it possible that having that terrifying experience could have caused it? and is it diabetes for sure or is that borderline? [/INST] A 5 is great. A sugar level of 6.2 fasting puts you in the pre-diabetes range. You could be carrying a diabetes gene and that experience turned your gene on, we can only guess. You do need to take appropriate measures to lower it a bit. Take a look at your diet and get rid of junk, add healthy fruits/veggies/whole grains (especially OATS), good fats (virgin olive oil, etc) and exercise. Now, on the other hand your 7.1 you received after the 2 hour OG TT would have been closer to 7.8 for prediabetes. Ask him to do a HbA1C to cut the tie. If you do have red, you want to nip it in the bud!!! A HbA1C should be 5.7 (optimally) to 6.4% A HBA1C of 6.5% is diagnostic of Diabetes. And, ask him specifically why he thinks 7.1 is prediabetic?? He is probably translating it into blood sugar for fasting instead of looking at the cutoffs for a 75 g OG TT test. If he is confused have him refer to the January 2015 Diabetes Care issues on the new Standards of Diabetes Medical Management. It is good for you to question the discrepancies, but in the end, ask yourself if you are being given warning signs? The HbA1C should give you further information. Good luck. A good diet never hurt anyone! </s>
