Thanks for your replies.
It's not anxiety or hyperventilating it happens quickly and suddenly. Before diagnosed and ending up in hospital 17 years ago I was treated for stress. I was borderline coma and spent christmas week in hospital being treated for type 1 diabetes.
My bloods have varied but no specific pattern I have seen my doctor who thinks it's an allergy but can't be specific. He has prescribed strong longer lasting antihistamines and inhaler to open up the airways.
It's not unknown that allergic reaction can be caused by:
Type or brand of insulin, infusion set cannula, metal of needle, tape or adhesive, preservative in insulins.
My pump failed last evening and I became unwell very quickly with blood sugars and ketones rising. My chest became tight , I was very breathless and dizzy. I changed my pod and found a lot of insulin around the site. Followed the guideline flowchart did correction dose , drank a lot of water and had pen ready to inject if needed. I must say when feeling so ill it's very hard to stay focused on what's needed. Managed to stabilise before bedtime went to sleep then awake at 4 with lows of 2.
My ongoing symptoms are the same as described above I monitor blood glucose and ketones.
Have requested Freestyle control Solution to test my meter is working properly.
Seeing pump consultant next week I know she will say it's not diabetes but I feel it's the medication, tools used to treat it.
That being said there are days when I feel really well probably 2 days out of 7 just wish I could pinpoint what is causing these episodes where I am left feeling so unwell.
Thanks again for your help.
