Sudden blood glucose jump to 12 when doing nothing, but diagnosed as non diabetic

[TheGreatGateway]

Today I was lying down playing a video game and waiting for a taxi. It had been 4 hours since my breakfast (Weetabix) and my glucose numbers seemed fine then. Suddenly all my vision dimmed and I began to sweat and feel irritable for no reason. I checked my blood sugar and it had jumped to 12.5mmol/l! This is not the first time it has happened, and it happens randomly, usually with a spike but one time also dunking my glucose to 3 mmol instead. My diet is no different than normal and weetabix has never done this to me before.

According to my Hba1c and fasting glucose I'm not diabetic (5.1% and 5.2 mmol average) but I'm terrified that these spikes are causing me harm and that I actually do have diabetes after all, especially as it takes ages for my post meal glucose to decline. What's going on?

Obviously I cannot diagnose or know the exact reason why you are getting high spikes and unusual readings.
But, I can say those symptoms and the sudden quick rise could be the cause.
Fluctuating blood glucose levels will cause symptoms. The more severe, the worse the symptoms.

However, until you use your glucometer in a way that tracks your blood glucose levels in a more regimented way, can you see if it is your usual response to certain foods.
My advice is to keep a food diary, recording your pre meal levels, then one hour, then two hours after first bite.
A food diary will help your GP, and depending on those readings, he can get you the tests necessary for whatever is going on.

Having normal fasting levels and getting spikes into the teens, if there is too many carbs and sugar in that meal, will probably be a normal response.

Weetabix have a shipload of carbs in them...
