Hi, I'm a 23y/o female with BMI of 18, not sure if I'm a prediabetes or in fact more than that. Recently feeling lightheaded around 1hr after eating or 4-5hrs after previous meal. Went to my GP and she ran a random blood test and thyrodism. I was told that my results are normal, but i didn't get to see them. I raised my concern on blood sugar levels and she insists that I'm no where near diabetes or low BG. After doing some research, i bought myself a blood glucose meter. I have tested for a few days and my fasting BG are always 5.1-5.3mmol, and 4-5hrs after meal when I'm feeling dizzy I'm usually at 4.4-5.1mmol which is not hypo at all, but my 1hr post prandial BG readings are crazy, Breakfast (<15carbs) - 30g plain oatmeal + 30ml wholemilk 0 mins - 5.3mmol 60mins - 8.5mmol 70mins - 6.4mmol Lunch ( <35carbs ) - 40g plain oatmeal, egg and small of of(carrots, brussels , sweethear cabbage, garden peas) 0mins - 4.8mmol 60mins - 11.8mmol 80mins - 6.9mmol Dinner ( < 20carbs) - 125g cooked white rice, 45g chicken breast and some leafy vege 0mins - 5.2mmol 60mins - 8.5mmol 120mins - 6.3mmol Any suggestions on whether I'm prediabetes or more? As I'm aware that normal people dont get their BG spikes over 7.8mmol.
