[QUOTE="Sapien, post: 2071288, member: 507939"] I had a fasting blood glucose of 5.8 mmol (105 mg/dL) on a lab test. Two tests were both about the same level. My A1c was 5.0%. My doctor says I have impaired fasting glucose. I got a meter and have been testing my response to carbs, protein and fat. Today I ate breakfast which included a veggie omelet, about a cup of beans (pinto) and some sweet potato. I tested at 1/2 hour 9.6 mmol (172 md/dL), 1 hour 6.7 (120) and 2 hours 5.7 (102). At 3 hours I was back to 4.7 (88) which was about the same as fasting upon waking 4.9 (89). I have read that most people only test at 2 hours (sometimes at 1 hour). If I only tested at 2 hours I would have never seen the big spike. I would have thought the carbs didn’t have such a big effect- only +0.7 mmol (13 mg/dL). How concerned should I be with the spike at 1/2 hour? It seemed really high to me. My understanding is any time the blood sugar goes over over 7.8 mmol (140 mg/dL) not normal and can lead to damage. It isn’t clear for me if a short spike like that if really bad or not. It makes me want to test simple carbs at 1/2 hour to see how high they would send me. I have normally not seen any numbers over 8 (144) at one hour or 6.7 (120) at two hours. I have noticed that when I eat more carbs than protein/fat that the spike is quick and when I eat mostly fat/protein with only relatively little carbs that the rise is of course much less but takes longer to peak - usually closer to the one hour mark. One other thing I have noticed is that when I wake up my blood sugar is usually between 4.5 (81) and 5.1 (91), if I don’t eat for a couple hours it rises sometimes as much as 0.8 (14). If I eat just a little fat/protein (e.g. a bit of cheese), it will drop a bit from the wake up reading. [/QUOTE]
