Psychological Stress


                                                        Stress and the Digestive System

       The stomach and intestines actually have more nerve cells than the entire spinal cord, leading some experts to call the digestive system a "mini brain."

In recent years, doctors have uncovered a remarkably complex connection between the brain and the digestive system.

Stress is especially troubling for people who have digestive problems without any clear physical cause -- "functional gastrointestinal disorders" in medical speak. In these cases, every part of the system looks healthy and normal, but they still don't work as they should. These disorders are extremely sensitive to stress.

If your digestive system isn't running smoothly, don't suffer in silence.

If your doctor can't find a physical explanation for your digestive troubles, you may need to calm your mind before you can calm your stomach.

Digestive problems might be a message. Roughly translated, that message is "Live well and learn to relax."

In fact, experts now see stress as a major player in a wide range of digestive problems, including irritable bowel syndrome, indigestion, and heartburn.
