First time posting here and I hope I’m in the right place and not overstepping any boundaries.
I will try to keep this simple as it involves a history spanning the last couple of years. Over the past 3 years my fasting blood sugar has been hovering between 88-115 (just recently was 115 last month during a routine physical but I was very stressed out the evening before and morning of regarding a different matter so I’m not sure if my stress levels reflected in my blood sugar. Previously it was never this high, highest was 103). My a1c has ranged between 5.5-5.7 (mostly always 5.5). I am on a statin for a family history of high cholesterol and heart disease but my lipid panels are totally optimal. I go every 6 months to my cardiologist for routine blood work and that’s why I am always exposed to my blood sugar ranges.
Technically Based on the above numbers I am prediabetic. I am 5’11 180lbs and can lose some more weight from my midsection but I’m not out of shape. Three years ago when I first got a reading above 100 I weighed 230lbs and gradually took up exercise and gradually lowered my carbs until I’ve reached a point where I eat a low carb diet (can’t say strictly keto)
Long story short I’ve been trying to get to the bottom as to why on occasion my fasting blood glucose sometimes tops 100and my a1c although no diabetic fringes on almost prediabetic (with once instance prediabetic at 5.7 a couple of years back). I bought myself a glucose meter and noticed 1) my blood sugar goes up after exercise and hangs out there for like 2 hours or so in the 110 range and 2) my blood sugar after meals are always optimal (never tested after a carb heavy meal because I don’t eat carb heavy meals except when on vacation)
My cardiologist suggested I go see an Endo to curb my curiousity/concern and I have an appointment scheduled for next week. In advance of our consultation she ordered blood work for me which I took and everything came back within normal limits except for the c peptide which was literally a tick below normal at 0.79 (normal range is 0.8-3.4). I fasted at least 10 hours before that test and the day before only at one meal (I do a lot of intermittent fasting). My fasting insulin was 4.4 and my fasting glucose was 88. My a1c was as usual 5.5.
I want to assume that the low c peptide is a product of my low carb eating and intermittent fasting and hopefully not an early indicator that I am developing LADA. Unfortunately no antibody testings were ordered so I have no clue about autoimmune possible issues. I’m trying to figure out if I’m truly no diabetic or if I’m just very well controlled and of course rule out the slim possibility of LADA. Any insight would be appreciated in preparation of my upcoming consultation
