Unexpected high sugar levels

Morning all

I have had high levels for the past two days and can only put it down to bad insulin?

I'm half way through the novarapid pen and noticed yesterday it went high and this morning I woke up with 7.1 and had a normal sized bowl of cornflakes and took 5units and my levels have risen to 14.4

Can anyone advise of the insulin is bad and I should start a new pen ?
 
Honestly if in doubt I'd start a new pen.

There are lots of other reasons why your bgs might rise (from illness to, according to some, wrong coloured socks) but changing the cartridge is the first thing to try,

Also you might want to check that your pen isn't faulty,as in injecting the right amount of insulin?

How about your basal insulin? Could that be at fault?
 
High readings (how high?) could be caused by lots of reasons. For instance: less exercise than usual, mis-counting carbohydrates, a virus, or an infection. But do start a new pen, in case it is bad insulin.
 
I hope I’m not in the wrong section here but your post is similar.

My 1st blood test was 4.8 (I am T2)

Stayed in as felt incredibly tired & but if a tummy ache. My breakfast was the same I have every morning no change.

A little niggle said check your blood again and it came back as 14

Any suggestions what I should do & why my lowest reading has suddenly jumped so much?

Thanks in advance, JoMar

The best way to check if your insulin isn't as effective as it was is to take an injection and wait for your blood sugars to drop 0.3 mmol/l before eating. This can vary for me between 5 minutes and 40 minutes depending on where I am in my vile age, my injection site, etc, etc.

Before changing my insulin regime in any way, like @EllieM stated above, I always check my basal first by meal skipping (or eat no carbs) to see if my blood sugars stay level.
 
My first check would be to wash my hands and take another finger prick reading.
Before jumping to any conclusions, I double check the readings. If it is from a CGM, it could be faulty (and they often over estimate highs). If it is from a finger prick, I may have something on my fongers affecting my readings.
If i then believe it is the insulin, I change it,
