that's not completely true--type 1 diabetics require insulin, or they'll go into a coma from high blood sugar. (A friend of mine died in high school from this.) A lack of carbs, combined with too much insulin, will cause blood sugar to plummet, which causes an insulin reaction (also called insulin shock). So it's dangerous on both ends, but only a lack of insulin will send a person into a coma.
Beautiful,wonderful!
I have a granddaughter that is a diabetic - she is 5 years old--and was just diagnosed last December so I am still learning, but I do know that on several occasions she didn't eat her breakfast, and would be jumping and playing one minute, and the very next, she would be passed out, and we would have to shove cake icing or honey in her mouth--
Luckily, she "came to" after that, but what would have happened if we weren't there to put the honey or cake icing in her mouth?
Her uncle was 23, and had the flu, couldn't keep any food down, and died in the middle of the night.
So much confusion on this issue.
Yes a lack of insulin will eventually send a diabetic into a coma if they continue eating, and don't take insulin, but it will take quite some time.
On the other end If a person takes insulin, and doesn't eat, their blood glucose level will drop, to the point they will pass out, if they don't immediately get glucose into their system they are DEAD! This can happen in a short time.
Some of us are fortunate, we can tell when our blood sugar level starts going low, others don't notice until it gets very low.
