Two weeks later - testing rapid insulin

26 June 2019

All my cancer tests were clean ...whew....No indication of any cancer events.

My prosthetic leg is behaving for a change. I did a 5km Park run in 1 hour 3 minutes.

I am learning a LOT about diabetes.

I get weak and dizzy after an insulin shot, so I tested 30 minutes after, and BG (blood glucose) was high, not low. I don't understand. I'll have to ask Dr.

If I wake up with a fasting BG of just under 7 mmol/L (126 mg/dl), and then eat breakfast of oatmeal and blueberries, my BG will rocket up to about 15mmol/L in 30 minutes, and still be about 12 mmol/L after 2 hours. Obviously my slow release insulin isn't handling that very well.

To really see what my BG levels are doing requires many finger pricks a day. Normally I do one when I wake up, and one about  2 hours after every meal. I have a few timers that I start when I start eating, to warn me 2 hours later.

Because oatmeal and blueberries are consistent with the BG variations, today I am trying something different.
 A shot of fast acting insulin is called a "bolus" dose. a shot of slow acting is called a "basal" dose. Basal are usually only once a day, while Bolus are before each meal, or when ever needed.
Bolus doses are used for two reasons. One reason is to counteract the carbohydrates you are going to consume, and the other is to lower your current BG.

The fast acting insulin my Dr. gave me is called Novorapid.
Their web site mentions that the "normal" reactions of Novorapid are:
1 ui of Novorapid will lower the BG by about 2.7 mmol/L (50 mg/dl).
1 ui of Novorapid will counteract about 15 mg of carbohydrates that I eat.

Before breakfast (oatmeal with blue berries)  this morning I tested my BG 6.4 mmol/L (115 mg/dl).
If this had been high, then I would need insulin to lower it. I am happy with 6.4 so no insulin is needed to lower it.
The 50g of oatmeal has 30g carbs. The 43g of blue berries have 6g carbs. Total carbs for breakfast will be 36g carbs. This should require about 2.4 ui of Novorapid to counter act the carbs.
I shot myself with 2 ui Novorapid, just before I eat.
One hour later I feel dizzy, and my BG is 12.7. Dizzy usually means low BG. Mine is high. I thought the Novorapid would stop the spike. It didn't.
Obviously I don't understand all I know about this.
