There are 2 main areas coming to light in the statistics. Firstly if you are obese then a much higher level of complications. We know that can go alongside high BG levels in some type 2s so I think the focus needs to be on keeping BG as close to non diabetic as possible.
For some people that may mean weight loss but high BG weakens the immune system so perhaps the ICU staff need to think insulin even if the patient is tablet / diet controlled. Just my thoughts!
Where an individual is very overweight, it is possible their breathing can be impacted on a day to day basis, by a number of factors from having a thick neck, to sleep apnoea , or even through mechanical compression of the lungs by other body parts, then blend in a respiratory disorder and it can all add up.
@Beastie_boy82 - I think for everyone living with diabetes, it is important at his time that we are very mindful to keep our numbers under control, and where possible also keep a close eye on our weight.
My levels have been in a decent place for over 6 years now, and much of my lifestyle has become almost second nature, but right now, I am mindful not to be having too many bored trips to the fridge, and to keep my exercise up.
