Agitation, anxiety causes of gastrointestinal disturbances?

Too much adrenaline! Fight or flight, anger or fear, when these responses produce adrenaline but we are not really in danger, the body has to get rid of the adrenaline and dumps it into the stomach where it mixes with stomach enzimes and creates gastrointestinal disturbances. You can treat the negative symptoms with medication or learn to think in a healthy way and not get your adrenaline going in first place.
