I am completely confused about how blood sugar control is working in my body. I am not worried about my numbers (in fact, I'm quite pleased), but I am totally confused as to what is going on and was hoping someone could supply a reasonable answer (I'm drawing a complete blank).
I'm a 39 year old woman, active (exercise 6-7 days a week) and normal weight, with a history of blood sugar problems. In 1995 (in college) I was diagnosed with reactive hypogycemia (and checked my sugars for 2 months to figure out how to eat - basically the same reduced carb approach as diabetes). I had gestational diabetes three times - 2002, 2005, 2006) (on insulin the first time since I wasn't diagnosed until the third trimester and had trouble getting my fasting and post meal numbers under control, but controlled by diet and exercise the next two when diagnosed at 14 weeks). In 2010 I was diagnosed with prediabetes and tested for about a month to see what I needed to change in my diet. So, I have had four episodes where I have tested my sugars regularly and (other than my first pregnancy) I still have the records. I typically had fasting numbers in the 90s (sometimes low 100s) and 2 hour post numbers between 100 and 120 when I was watching what and how I ate. I have been eating a balanced carb/protein diet for most of my life and 2 years ago I gave up wheat (I also have endometriosis and that led me to remove wheat from my diet).
So, here is my confusion: About 6 months ago I switched to the South Beach diet since my a1c numbers remained in the prediabetic range. Recently I've been super exhausted and not felt great so I got some strips and started testing. My numbers are terrific - I mean I have NEVER seen such good numbers in any previous testing experience. My fasting numbers are in the 80s, my 1 hour post meal numbers are typically under 100 (and almost all have been under 120 even when I push the number of carbs I feel comfortable eating). I've even seen several post meal numbers in the 70s (numbers I have never seen - in college my low numbers were in the 60s never in the 70s). So, clearly, my exhaustion is not blood sugar related. What I am wondering is if something like the South Beach diet can have that much of an affect on the way my body handles blood sugar? I am thrilled, but I want to figure out what the change is so that I can keep it up! FWIW, my a1c in Dec 2012 was 5.8 and my fasting was 94.
Again, I want to emphasis that I am not worried (nor am I bragging!), I am just very confused. Anybody have light to shed on this?
Thanks!
