HIGH blood sugars!
For the last 4 days after dinner my 2 hour post meal has been 11 +. Now I am trying to keep my patience but I am struggling to hold it in any more, also this evening I even injected more than I was supposed to by 30 g and still went up to 13.7, 2 hours later. Can someone please explain what is going on and give me their input if they have experienced something like this, I know to a lot of you this might not seem like much but to me it is making my evenings and nights hell as I refuse to go to sleep until my blood sugar is down and correction doses take a while to work.
 
Hi @james122 im sure people can understand why that's not very pleasant for you.

Can you give a bit more information? What were you levels before eating? What are you eating for dinner? What ratio are you using & how much insulin did you bolus? When did you bolus in comparison to eating (before/after/at the same time)?
 
Hi james-- getting readings quite high 2 hours post meal could indicate that your I:C ( insulin to carb ratio ) needs to change.
as catapillar asked above perhaps more background info would help to look at your numbers to support.
 
Are your other test results OK? Maybe you need to change your carb ratio for your your evening meal. In fact, if it's only your post evening meal result that's high, 4 days is enough to merit raising your bolus.
 
Yes in response to your questions, before dinner I am usually below 6 mmol/l and I bolused for 75 g and ate about 45g and my carb ratio has to frequently change but for the last couple of weeks I have been on 1:10 so quite a high dosage. I also bloused 30 minutes before I ate and all my carbs were slow acting so I am very confused.
 
If this has only started happening a few days ago, you might want to change your insulin pen/vial/cartridge just in case it's gone off and lost effectiveness.

The other thing I'd do is check my carb counting as that will also rule out one variable.

Try not to,stress as that can make blood sugar higher.

You could experiment by eating the same meal for a few nights - exactly the same. Then you can see what insulin dose fits best and that will help you check your ratio. When I do that, I try to eat carbs that are easy to weigh/count, and I don't have high fat because that can interfere. So I might have something simple like potato, meat and leafy green veg.

I'm sure you can sort it :) If you increase your ratio, go slowly and cautiously and test lots.

Edited to add that it's also possible you're coming to the end of your honeymoon period. You'd see your insulin needs rising then.
 
@james122, you should do a basal test to make sure your high bg levels isn't a result of too little basal insulin.
 
That is really good advice from @azure -- that is exactly what I do myself -- if I am unsure of something I will repeat the meal until i get the results I want
 
What long acting are you on & when do you take it? I just ask cos it could be that your basal dose is running out by the evening, possibly - do you split your basal dose?

It could be that you need to up your ratio & I would agree that the best way to figure that out is to eat the same thing 3 or 4 nights on the trot. You would need to be pretty certain of the carbs so it would all ideally be weighed etc & nothing too fatty/cheesey because that will slow down the carb absorption - but try to make it a meal you like if you are going to be eating it 4 nights in a row & you will always have that meal as one you are certain of the carb content of once you've weighed it once!
