I have not been officially diagnosed with diabetes. My A1C was 8.5 with normal FBS levels. My doc has never seen that before so he said to keep a food and BS log for the next 3 months with no meds and we would test again. All my BS numbers, before, after, bedtime, morning, hours after eating have all been in normal range so I have no idea why my A1C was so high. Anyway, I decided I wasn’t going to wait for 3 months to see if I really had diabetes or not, so I started 16:8 fasting and low carbs. I started only 3 days ago but my FBS was 67 today and has never been that low. Can anyone tell me what that means? I am not on medication. Can diabetics get low FBS if not on medication? I read that its normal for non-diabetics FBS to drop a little fasting but its not for diabetics. Sorry for a million questions, I am just trying to understand whats going on with me!
Did you ever have any other A1c test before that? Did your doctor repeat it? (lab errors are rare, but do exist). Did you take steroids recently? Do you have any condition that falsely increases A1c results?
- genetic variants of hemoglobin
- iron deficiency
- B-12 and folate deficiency
- absence of the spleen
- (high dose) daily aspirin and vitamin C
- narcotic pain medications
- certain kidney and liver diseases
When you have your a1c done fast beforehand. Then have them also do a FBS. Simultaneously, test your FBS with your meter then compare your meter FBS with the lab’s FBS. Also if you know someone who let your use their meter for comparison.
