Hello Friends,

This is my first post and it's out of desperation. I have been diabetic for decades and have only had good control sporadically, were talking months here out of decades. I'll say more about that at some other time. It would fill a book!
Here is today's problem. My morning fasting sugars were 205. I took 7 units of Humulin R and 10 units of Humulin N (pen) 1/2 hr before breakfast. Brkfst was two fried eggs, in butter and 1oz of cheddar cheese. Two hours later my test results were 257. What's going on? Liver dump? Oh, and two cups of coffee with cream and Splenda drunk slowly over the two hours.

Thanks ,

If you drank regular coffee with caffeine it could be that. Caffeine can raise blood sugar quite a bit. I had to give up caffeine a long time ago because of that.

Welcome to the site ronbo! Let’s hose you down and reduce this desperation?! No need for it. Feed it, it gets larger…

Based on your post eg decades and using both Long and short acting you are a T1 correct?

Let’s go down the “list” of possibles? Fingers cleaned with hot water ensure the readings themselves were “kosher”? Do the readings in a cold/hot wet or humid place? These factors can skew readings easily…

Fifty points is a puzzle not a terror. Do NOT make it a terror!!! It ain’t, only a unpleasant math problem.

Did you put the R & N in entirely different spots in your body??? You cannot put them in the same location. Presume you are aware of that after 25, yes? Left side right side fine but not the same leg the same side of the belly…

Did you get any backflow? Insulin that came back out after you injected it? Remember keep in in place for 5/6 seconds then remove the needle. Typically takes care of that issue.

For the short acting you use a favorite injection spot? Could be scar tissue beneath the surface… that could distort the absorption. Still breaks down after 4 hours but delays the typical absorption just a little.

One day is NOT a pattern, it’s an annoyance. Perform the same procedure 2-3 days in a row THEN change and you figure out if it truly had no effect or whether you got a truly random result. Get a
Month of them and you’ll see real clearly if there is a true issue.

Not ALL bg is food caused. Could be the somegil (sp.?) effect, the mysterious morning rise that most get. That’s hardwired into us as a species. Need sugar to outrun the creature trying to eat us for breakfast once upon a time. There are tweaks but gotta be real careful because it’s the long acting that you tweak as such much more danger (sic. it lasts a lot longer). Short acting out of the body totally in a few hours… long acting gets the theme music from jaws when it misbehaves.

Nothing you describe eating will cause big rises. Protein, fat, milk sugar, whichever sweetener you used. How did things look at hour 3, or 4? That should write this “script”… it’ll help you tweak, if, IF you really need to. But one reading not the best pattern with which to change!

You have “vigorous fun” with a partner the night before? Depending on the length of that -vigor- could still be adrenaline floating around. If not intimate exercise how bout hard regular exercise in the last 12 hours.

All kinds of possible.

Get a larger pattern 2 hrs post meal. Then explore the data. Regardless 250 is not scary, and should not be. A week, a couple weeks a month ok then you got a diabetic hardy boys mystery see if you can find the cause(s)

Let us know what you find out.

After a meal, even with insulin there is a rise. I would not expect my numbers to drop immediately after eating even having taken insulin. Is this something that you normally do and track? Is this an abnormal reading (a 45 point rise is not a bad rise)

As others have stated, that there could be many causes. Did you test again a little later to see if the drop started?

When I first went low carb, my numbers would go up because my body was used to having glucose and my liver was full. So as I at low carb over a longer period of time, the liver has less to offer, my body is not freaking out by a low carb meal.

From my experience, I would increase those dosages by about 5 each time till i found what works ( and document it) and then let my doc know my results. But that's just me, I don't have any problem experimenting on my own. You have to put yourself in the proper mindset and then follow through.

Thank you all for your concern and willingness to be of help. I nave never been good at following instructions and making lists or keeping track of things. Which is why Diabetes self management has never gone well for me. I've never heard the term "correction factor" The idea that anyone could know how much one unit of insulin can account for however many grams of carbs is astounding. I'm doing a lot of belated research, I'll post again as soon as I figure out a few more things. Oh, one more question… How do you know how much insulin your body needs in the first place? Without that info it's all guess work.

Ronbo, there is no one right answer to your question since we are all different, even though we all have diabetes. My insulin sensitivity is very high with a sensitivity factor of 100 which means that 1 unit of insulin can be expected to reduce my BG by 100 mg/dl. I suspect that your sensitivity factor is much much lower and that you need more daily insulin to stay in control than I do. (I use from 16 to 18 total units of insulin per day. If you use more, your sensitivity factor will be lower.) Your sensitivity factor is initially calculated by how much total daily insulin you need to maintain control. Gary Scheiner's book "Think Like a Pancreas" has a chart showing insulin sensitivity factors based on this. His book was key in my understanding how to treat my diabetes with insulin. He also has a whole chapter on "Bolus Calculations" with a sub-section on "Insulin to cover carbs" that should be helpful to you. In that same chapter is a section on "Insulin to correct blood sugar" His book has become my go-to manual for dealing with my diabetes.

hello just wondering what did you eat before bed time and then you ate carbs for breakfast you will have to monitor all that you eat so you can adjust your insulin and check with your doctor keep us updated

Short answer: no idea. 205 is kinda high, do you agree? I use a pump with Humalog. I don't see any carbs in your meal to cause the BG to rise. Well, sure, the liver is releasing glucose. or, some adrenaline or other endocrine stimulated release of glucose from liver ("gluconeogenesis"). No idea.

It could very well be Dawn Phenomenon or possibly poor insulin absorption due to scar tissue if you don't regularly rotate your injection sites. I'm on an insulin pump and it has been years since I've used Novolg and Lantus on MDI. Prior to that I was on 2 daily shots of NPH. The action time for Regular insulin (R) starts in 15 to 30 minutes and peaks between 2 and 3 hours, lasting a total of 4 to 6 hours. The peak activity of Humulin N typically occurs approximately eight hours after your injection. The duration of activity is approximately 12 to 16 hours. The activity profile of Humulin N makes it useful for maintaining a relatively constant level of insulin in your bloodstream if administered twice daily. So, the Humulin N wouldn't have much effect 2 hours after injecting it. Do you have a correction factor that you use? I know that after 41 years as a Type 1, I have to adapt my insulin therapy to my changing body as it ages…what once worked may not work so well anymore. May be time to re-evaluate your carb to insulin ratios for your R insulin as well as evaluating your insulin sensitivity and correction ratios.
