It looks like General Petraeus suffered from a bit of low blood sugar and collapsed during a Senate hearing. Fox News has the story:
Gen. David Petraeus appeared to have passed out during a Senate Armed Services Committee hearing Tuesday, recovering enough to be escorted from the room.
The head of Central Command was in the midst of a dialogue with Arizona Sen. John McCain when he slumped over the witness table. Several officials gathered around Petraeus, who was able to stand up and walk out on his own.
The committee recessed its hearing for several minutes as lawmakers and aides determined whether Petraeus was well enough to continue. Committee Chairman Carl Levin, D-Mich., suggested that Petraeus was dehydrated but had recovered quickly.
“General Petraeus appears to be doing very well,” he said.

Michelle Malkin tweeted that the general hadn’t had anything to eat before the hearing and was dehydrated. You do not want to mess with low blood sugar because it will wreak all kinds of havoc on your brain and body. Your brain gets its fuel from the sugar in your blood, so if you don’t eat enough to sustain your activity levels, your brain will literally shut down, which is what happened to General Petraeus. In sports such as long distance biking, this is called bonking.
I’ve had hypoglycemia for several years and even passed out a few times before I knew the cause. If I don’t eat a good combination of protein and carbohydrates for dinner, I can have a hard time in the middle of the night. There have been times when my blood sugar has dropped so low so fast that it’s woken me up from a deep sleep. When that happens, I go downstairs and get something to eat. I have glucose tablets, but I don’t like the sugar rush and I end up crashing later. Instead, I like to have a big glass of milk or a yogurt and then lay down until the symptoms subside. In about ten minutes or so, I’m much better and can get back to bed without having to worry about suffering a sugar crash later.
Update: CBS has much better video in which you can hear the general say, “I need some sugar,” just after he stands up.
