My last 2 HbA1c were 95 and then 84.
Reading this morning was 7.8. I was quite disappointed with this as I thought it would have been a bit lowest
According to your hba1c your average blood glucose must have been around 14. I think waking up at 7.8 is brilliant in comparison!
(Top and bottom line in the chart, ignore the middle ones.)
The only way to find the right dose of insulin for anyone is by trial and error. This means starting on a relatively low dose to bring bg's down slowly for safety reasons.
Imagine starting on, say, 25 units and then finding out you only need 4 units... You'd need to eat all day and through the night to compensate for this, if not a glucose drip because the basal works all day!
The other way around is much safer. If you start out with 10 units and it turns out you need 80, your dose will be titrated up slowly until you start seeing the numbers you want. This way you'll have higher numbers for a couple more weeks but no blue-light trips to the hospital.
With your 7.8 you're already very close to a healthy morning bg!
