I think there are extra problems that come with being diabetic if we get injured. A lot will probably depend on what sort of treatment regime you are on and how good your levels of control and knowledge of managing your diabetes is. Higher overall levels will make the risk of infection higher and can result in things taking longer to heal or needing much closer attention. If hospitalised, there will probably be day-to-day difficulties like maintaining good activity levels and also the kind of diet you are used to to help keep your levels good.
A few years ago, my right femur snapped when I was at mile 23 of a marathon - I didn't finish it! At that time, I wasn't diabetic, but I do wonder now how I might have coped. I could barely walk for about 5 months, and in the first month my body demanded so much energy to try and heal the wound that I was consuming well in excess of 6,000 calories a day - in the form of cakes, biscuits, sweets etc. Despite this, I didn't put on weight, I simply burned it off! Additionally, there was a lot of stress from the pain and worry which would also have raised my levels. So yes, I do think that things can be much tougher as a diabetic 😱
