So you don't have any episodes since changing you're diet?
Until you know what is causing the problem, and it is more than likely, food! And probably carbs and sugars! You won't know!
Once I was diagnosed and not given a choice on how to control my blood glucose levels.
I tested, tested, tested everything that I liked in various combinations or on their own, until I was satisfied, that what I was eating didn't make me go hyper, then hypo!
I didn't change my diet, I changed my lifestyle.
I changed from eating three meals, to 7 smaller meals. I ate to my meter, and stayed in control.
I changed from a 16 stones, very ill, struggling old man.
To a 11 stone happy, healthy, much younger man!
My ill health problems and there was a long list of them. Where going to put me in my coffin!
Now with a little bit of luck I'll be around to see my great grandkids!
I understand your disbelief, I had it, before diagnosis, but with a couple of very helpful, knowledgeable people, I have, learned to see the right way for me!
Hope this helps!
