Doctor confused: So am I: Good a1c, high bs
I live in Japan. The health standards are high here. Because I'm larger (Canadian living in Japan) I often get asked to have my blood checked, even when the issue is something unrelated (Injury at the gym etc).
For years, my doctors have always said "OK, well you're not diabetic." and I get treated for whatever it is I am in for.
Last July I was placed on CPAP for sleep apnea. After being placed on it, I started to feel much better. However, my ha1c went up from 5.3 to 6.3 (The standards for measuring are different in Japan, anything below 6 is normal, above is pre, over 7 for a prolonged period and meds are considered). I don't know what my fasting blood sugar was when I first found this out.
I adjusted my diet and my gym routine (More cardio on off days). However, my a1c went up to 7.4. A friends father suggested the amount of stress I had over the course of the last year (Work, family, living in another country for so long) was impacting everything. Still, I adjusted my diet even more.
I decided to wait 6 months instead of the usual 3. I went in today and my a1c was at 5.6 and the doctor seemed very happy. I asked about my fasting blood sugar and it was 175. I asked him why it was high and he said it was likely something I ate (He didn't know I had fasted). He wasn't sure why I had such a high bs but normal a1c. He asked me to come in again in 2 weeks.
He said the only real possibility he could think of was that the night before (I had some serious family issues) my liver dumped glycogen into my system and that was what was left over. Still, he said looking at the rest of my exam (I had a complete heart check, stress was killing me and I thought I was going to have a heart attack soon, needed peace of mind) he wasn't sure what advice to give other than to keep doing what I'm doing.
I should also mention (As I mentioned to my doctor) that for the past 3 months I've been drinking more alcohol. I was a social drinker, but the last 3 months alcohol has been my drug of choice to 'chill out'. He said that it would have affected my a1c. I had nothing as far as alcohol this past week.
