Hi,
Sorry to hear that you are having trouble with your sugar levels. I was just wondering - what are you eating? If you are eating something that is high in protein then that may be why your sugar levels are spiking after a couple of hours. Protein is converted to glucose, but at a much slower rate. Also fat can slow the digestion of food. (hopefully someone with more knowledge or a better explanation can help when they come along and read this soon!)
To get an insulin pump you need to fill certain criteria - do a search online and it should come up with who qualifies to get an insulin pump from the NHS.
I got one due to constant low sugars (it was swinging between being high and low). I have found that the pump is helpful to keep my fasting blood sugar levels stable as I can adjust the amount (of short acting insulin) I am giving myself by the hour. However, this did take a LOT of testing to set up and was a bit frustrating, but it was worth it.
The other thing I can do on my pump is to give myself an extended or dual bolus when i have eaten. Extended bolus - give myself insulin to cover my meal over a number of hours. Dual bolus - give some insulin to cover my meal immediately and the rest over a set number of hours. This I have found helpful to cover a low carb, high protein meal or high fat meals. However, for me personally I found that the insulin pump did not solve all my worries and so I chose to go low carb.
I would look in the insulin pump forum on here to find out other people's experiences of using an insulin pump.
