A.
 During the night your liver is involved in modulating blood sugar with insulin. If you have diabetes or pre-diabetes or even metabolic syndrome, this modulation overnight is also not right. That's why fasting blood sugar can be high.
It can be because of the insulin intolerance you might have - meaning your body doesn't use insulin effectively in metabolizing blood sugar. Or it can happen because of the way your liver releases glucose. Your liver releases glucose (blood sugar) during the night to provide you with enough energy to function until you eat again. (This always happens between meals) But in diabetes the signal that your insulin-glucose mechanism sends to the liver to stop releasing glucose is off and therefore your liver simply releases too much glucose during the night or in between meals in general.
