If you're not normally an angry or irritable person and suddenly feel aggressive, your stomach may be to blame.

Researchers at the Texas A&M Health Science Center School of Public Health say the emotional connection between your stomach and your bad mood actually has a scientific explanation.

They describe the condition as 'Hanger' or 'Hangry.' The mood swing happens when you haven't eaten frequently enough to keep the glucose levels in your body from getting too low. When the level drops below normal, the brain starts releasing stress hormones.

According to the study, it's a physiological response our body uses to indicate it's important to go find food. The body's reaction is less self control, making people more likely to react negatively to situations they can normally deal with.

If you see someone acting 'Hangry' or you are starting to feel 'Hanger,' the cure is simple, just eat a well-balanced nutritious meal. You can avoid 'Hanger altogether by not going too long between meals.
