Hi,
Im hoping for a bit of help.Ive been feeling very tired for about a month, vistied my doctor on Wednesday who has booked me in for fasting blood next week. Anyway, today at uni i was reading and all of a sudden my vision went blurry; couldnt read what was on the page and had to put my book down. When i stood up i felt very dizzy and came across all hot and flushed. One of my lectureres (was at hospital as im a student nurse) had a blood sugar test thing - sorry, i have no idea what it is called. He took a pinprick of blood from my finger which read at 4.3. Is this normal? I had already had 2 bananas, 2 crackers with cheese and a bag of crisps but he made me eat 2 chocolate biscuits.
A bit concerned as both my doctor and lecturer have mentioned diabetes to me now.
Thanks. x
 
Hi
No one can say for sure, though the blurry vision is a classic sign. However a 4.3 after banana, crackers, crisps doesnt suggest someone who has a problem with diabetes, cause if i had eaten that even with insulin Id be lucky to be under 10!
In saying that, the symptoms you had do sound a bit hypo and for diabetics anything under 4 is hypo so maybe if you have been running higher sugars and not knowing it, a drop to 4.3 might feel like that for you.Im surprised the person who took your blood didnt know how to interpret the results. I wouldnt think a non diabetic would feel anything at 4 so at this point its just too hard to say unfortunately, sorry.
Maybe you have reactive hypoglycaemic, maybe nothing? Blurred vision might just be tiredness and then anxiety about the blurred vision caused the dizziness?

You are doing the right thing getting a fasting blood test but make sure you get checked for other things too. Low blood pressure causes dizziness and often people can feel dizzy on standing quickly (orthostatic hypotension) but this is not necessarily linked to diabetes per se.

Let us know how you go, Fingers crossed for you its not.

It's possible your BG had fallen below that number, your liver had just woken up and noticed and dumped a load of glucose into your blood and you were back on the way up when you took the reading. Or what you ate sent you high and your pancreas overcompensated with too much insulin. I used to get symptoms from rapid BG changes.

Fasting BG may not show much, see if you can get tested around an hour after eating something carby, if your colleagues can't do this try a pharmacy, some will do a walk in BG test
