Irritable? It may be hunger and/or low blood glucose

From the BBC Future article “The brain science that explains hanger”


We now know the reason that hunger causes us to lose our temper. But is it true that women are more susceptible than men?

“We’ve long recognised that hunger leads to irritability in science,” says Sophie Medlin, lecturer in nutrition and dietetics from Kings College London. “But the wonderful world of social media has merged the two words for us and now we know it as ‘hanger’.

“When our blood sugars drop, cortisol and adrenaline rise up in our bodies – our fight or flight hormones.”

These then have an impact on our brain. That is because neuropeptides, secreted by neurons, control the chemicals in our brain. “The ones that trigger for hunger are the same ones that trigger for anger and rage and impulsive type behaviours. So that’s why you get that sort of same response,” she says.
