I've always wondered what I would use if I needed to keep my blood sugar under control. What do you intend to do?
Well, the big NUMBER ONE is: "Whatever my doctor tells me to do."
Before I was 'officially' diagnosed, and while the signs of onset were unmistakeably strong,
I went and bought Walgreen's teeniest little BG monitor for $9.99.
They only need a 0.5microliter sample nowadays, which is a half sphere of blood about 1mm in diameter.
I can barely feel the lancet and I'm usually quite the squeamish, whiny baby about needles. I learned how to do it over last weekend.
My initial readings were in the 300's (untreated.)
After 1 day on Metformin I came down to 286 yesterday and 264 this morning.
I am going to get seen again today and they may give me a bit of insulin to smack it down to normal. (maybe 80 - 110)
Type II (adult onset) can be very well managed with a careful diet, regular exercise, and medications.
Your body's own dashboard of meters is broken, so you have to go in there and take the data yourself, then YOU DRIVE.
Your system can't handle carbs and sugars and fats and stuff 'on automatic,' but you can know what you just added to the system by checking what's on the nutrient labels.
For me at this stage I have to discover a 'carb to glucose ratio,' and the way to do that is to take a blood reading before a meal, know who much carbs are in the meal, then check blood again after 2 hours. Doing this over about a week will let me know how my blood reacts to what I just ate.
Then I can avoid 'bad things happening' by avoiding things that I know would spike the numbers - ( a chopped strawberry shake made with double-yolk French Vanilla ice cream, and whole milk - 4.3% fat) - - or I can cut way down on the quantity and have just a small taste now and then.
People on insulin get to 'prepare' for an indulgence, rather than wait for the body to react (or fail to react.) If you know your carb to glucose ratio, you can figure what a butterscotch sundae will do to your numbers, and then apply an countervailing dose of insulin. (NOT GOOD PRACTICE. But people 'play' like this.) Thing is, if you then NOT have the sundae, or if you calculate wrong and you slam your glucose into the basement, then you could go for a coma, or get hypoglycemic and do stupid, stoner type things, like walk down the street naked...
Luckily I don't have a big sweet tooth - my vice is large meat servings with heavy sauces.
Every person's body will be different.
