Do Low Blood Sugar Levels Cause Fainting Spells?

I have a friend, age 91, who fainted a few weeks ago and fell and hit his head on a hard edge. He had a cut over one eye, and a cut on his nose, and went to a re-hab facility. He asked me today, why did I faint? and I thought perhaps it might be low blood sugar, or just lack of enough food?
