It's novorapud for a pump, it's a different vial from the last one so I don't think it's that'swhat sort of insulin is it? Has it expired? I'd try a new batch in case it is not "perfect" and see.....
I have the same amount of carbs for the meal as I'd normally have,
Possibly my socks lol, I do check with my contour metre too, there's bout 0.6 difference, the contour being the higher of the 2.Are you detecting the hypo with Libre only or have you tested with a finger prick?
I do not find Libre very accurate so it may not really be a hypo.
As you have noticed it the last few days, it could be a low reading Libre.
Or it might just be the colour of your socks
It's in general the same meals or similar, I don't vary too much as I'm happy with the meals I have and know how my bloods usually react.Hi, blueeyed81, could be just another bit of T1 randomness or the colour of your socks, but I'm wondering whether it might be the type of carbs in the meal?
Even though the amount in terms of grams might be the same, 40g of toast, for example, is going to get in stream a lot quicker than 40g of beans/pulses, so it might be if your recent meals have been lower gi, the insulin is getting to work before the carbs get in stream?
The pre-bolusing, splitting and amounts I dose for toast will be way different compared to pulses, even though the carb count is the same.
I use dual bolus for take aways, pizzas and Chinese especially, I'm still fairly new to the pump, I'm only 2 years in lolPresumably the Libre graph doesn't help? It does sound odd. The meals weren't higher fat than usual? I tend to get a dip after a high fat meal then climb later on. I'm new to pumping & currently experimenting with extended boluses to cope with it.

Hi and thank you, I'm going to email my diabetes team and see what they say. I'm currently only using my arms as when in my stomach 9 times out of 10 it's sore and an infection occurs. (my diabetic dietician is going to talk to the medtronic rep about what options are best for cannula, I've asked to try a different one, currently using the minimed mio). I am going from left arm to right and chaniginf every 3 days unless my bgs are high and won't come down. I'll see what my dsn comes up with.Hi @blueeyed81, Sorry to hear of your troubles.
Several thoughts based on my experience as a T1D on a pump, not as professional advice or opinion::
1) could it be that the cannula has been inserted into muscle rather than under the skin into what is
called the subcutaneous(s/c) tissue?
Insulin is absorbed more rapidly from muscle and can lower BSLs more quickly.
a) The cannula could end up in muscle at the time of insertion, with it causing stinging and pain more
widespread then the usual pain after insertion or
b) maybe the tip of the cannula is close to the tissue layer between s/c and muscle tissue and with pressure
perhaps laying on the area at night pushes the tip through into the muscle?
When I have suspected one of the above has happened I have changed the cannula and chosen a different site.
2) problems with Medtronic pumps have been reported - including errors in infusion rates - could
your pump be inputting more insulin than programmed into your tissue?
Some of that may be excess insulin from the basal program giving you higher insulin levels before you eat
and maybe the bolus dose in excess tips you over the line for a hypo to occur.
3) as others have suggested hypos can be due to the described effect of delay in absorption of food due to
gastroparesis - where the stomach holds onto food and releases it very slowly so that the insulin is acting
well before the food reaches the small intestine to be absorbed. You would need to check that out with a doctor.
It is a known complication of diabetes but that is after many years of diabetes usually.
see mayoclinic.org gastroparesis - diagnosis and treatment
4) if the problem of hypos soon after eating is persisting and getting more common and worse - that has
happened to people whose kidneys for some reason are not working well and insulin is not being broken down.
That is an urgent situation and needs immediate medical attention. see https;//doi.org/10.1136/bmj.d567
5) I do not know what else - somebody else might !!
So please contact your health team asap to discuss your troubles and see what they have to say.
What do they suggest you do whilst the cause is being sorted? ? change cannula site? ?
What about insulin dose?
Check what the pump is recording as amount of insulin delivered? Are you having to change the pump's
reservoir more often than usual?
Best Wishes for an easy answer and solution.
I'd say split the bolus on the pump 60/40 over the 5 hour time period and see how that goes.
