Being a diabetic, I have never seen nor heard of that one before. As for the low blood sugar, they need to abort right away. A snack at depth is not going to work quick enough, depth plays havoc on blood sugars and a diabetic should never dive when there sugr levels are BELOW 180. When they notice levels are low, it is not long before they could appear narced and their condition be misinterpretted. All they need to do is surface, have a pepsi and a candy bar and get ready for the next dive!
Okay. I need sources on this statement. Greater than 180? I don't doubt you are a diabetic but this makes no sense. Having blood glucose greater than 180 doesn't give any ... Let me repeat that.. ANY safety bro. Depending on the trend of the blood sugar it could drop from 300 to 30 in less than 30 minutes. Depending on your control, whether you take insulin, whether you ate before the dive, etc.
So I guess you have a few things to explain about how depth affects the release of insulin, or glycogenesis. I'll be waiting for you specifically but a more knowledgable source may chime in because I would like to hear what is being recommended to the diabetic divers out there ( insulin and noninsulin dependent).
