| There is a condition called Dead in Bed syndrome. Where the heart stops during sleeping hypo. But it only affects 1 in every 1000 type 1's and it maily affects children I think.
I was going to take part in a study at the university investigating this syndrome but the docs are using salbutamol to identify the condition and I already use salbutamol so i couldn't take part.
I have suffered many sleeping hypos and am still here. I think the chances of dying in your sleep are very slim as the adrenalin which is released usually wakes us up during hypo. But i have required the help of my partner on several occassions to treat the hypo. |
