Hello,
Thank you for choosing DoctorSpring.
First, let me assure you there is no reason to worry. Controlling Sugars needs some patience and perseverance. And it is never impossible. You will need to do is understand it well. At time when there is a chance in medication the bloof sugar values might take some time to be under control. The dose adjust is basically a trial and error method, and there is no 'single' magic dose for each blood sugar value. It varies.
Lantus is a good change from NPH if used well.
You need to target the fasting and premeal sugars with adjusting the dose of Lantus. Humalog before meals is more for controlling the post meal sugars. So I would like you to chart out sugar readings like this....Fasting, pre lunch...pre dinner....post Bfast, post lunch and post dinner (all 2hr post meal) on a day...and let me know...dont change your present dose of Insulin till then.

Hello Dr. Muthukrishnan
Thank you for your speedy response. I have been using accu-chek compass software to keep records. Counting carbohydrates has been a part of our daily life since my daughter was diagnosed.
her current carbohydrate intake is roughly 10 - 15g per meal/snack.
On average, she is having around 100g of complex carbohydrates a day.
The newest average BG data we have is as follows
AM, (fasting) 109,3
after breakfast 211
Before lunch 93
After lunch 178.6
Before dinner 126
After dinner 202
Evening 180
Her trend graph shows
Above target >140 41.7%
within target 70-140 50%
Below target 8.3%
Highest BG 310
Lowest BG 51
Average BG 158
Ultra rapid dosage was based on this guideline before changing to Lantus
Very low schedule (Insulin-sensitive)
BG 150-199: 0.5 unit bolus Insulin (regular or rapid-acting)
BG 200-249: 1 units bolus Insulin
BG 250-299: 1.5 units bolus Insulin
BG 300-349: 2 units bolus Insulin
BG Over 350: 2.5 units bolus Insulin
Her insulin needs have gone up since the change we now are in between the previous table and the following.
Low schedule
BG 150-199: 1 unit bolus Insulin (regular or rapid-acting)
BG 200-249: 2 units bolus Insulin
BG 250-299: 3 units bolus Insulin
BG 300-349: 4 units bolus Insulin
BG Over 350: 5 units bolus Insulin
Total daily ultra rapid dosages range from 6.5 UI to 8 depending on the day.
Her highest peaks happen at school(15:00), after snack time where she has under 10g of fiber rich carbohydrates.
She is currently 23 kg
Her previous NPH dosage was 15 UI divided in 2 dosages, 12 in the AM and 3 at night.
Our doctor switched to lantus using 11 UI based on the 80% rule changing from NPH.
I am an engineer and the last time I did the math I come up with 12 UI (80% of 15 UI). There might be a very good reason for 11 UI but I throw the question out there.
I hope this is enough data for you to get a picture of the situation. You may contact me david(dot)erikovich(at)gmail(dot)com.
Thank you again for your time and consideration.
Sincerely
David
Dear David,
I have gone through the profile in detail and appreciate your dilligence in maintaining it.
It is generally ok, except the pre-dinner levels. I suggest you make these changes. Lantus 12U at bedtime, Humalog 4U before BF, 6U before Lunch and 4U before dinner. Target premeal sugars at 70-110mg and post meal below 160mg/dl.
You haven't told me about the HbA1c levels.?
You can add the correction bolus as per your chart if the premeal levels are above the intended target.
Check again after 3 days and let me know.
Regards
