Hungry & Angry?
When blood glucose levels drop, your body releases stress hormones from the adrenal gland in response: cortisol and adrenaline – in effect, the fight or flight response you experience in situations that cause fear and anxiety.
This can cause your mood to fluctuate – perhaps you might experience sudden outbursts, or increased anger that you would expect when your body is in a fight or flight response.
Don’t forget that hunger and anger are linked to the survival of the human species – it is a normal, evolutionary, biological response to be more anxious, irritated, or angry when hungry. Only those ancestors who went in for the kill when they were hungry survived!
