The consensus seems to be that hypoglycemia may have something to do with the "dead-in-bed syndrome", but it is not the underlying cause. They have no idea
what causes it. There was a big hoo-haa about this a while back, with speculation that dead-in-bed was somehow caused by the switch to intensive therapy (MDI) and the use of modern insulins. But that seems to have died down, and I have not been able to find any new data about it ...
