The digestive system has a host of symptoms, principally nausea, vomiting, heartburn, bloating, cramping, diarrhea, constipation and flatulence. The onset of such symptoms may simply reflect a normal response to an unusual meal or be associated with some lifestyle factors such as improper diets or high stress lifestyles. Excitement, disappointment, fear, anxiety and other strong emotions can cause some distress in the digestive system.
The digestive system has a limited set of symptoms for expressing distress, so the same symptoms may also reflect any one of a number of very serious disorders, including gastritis, or inflammation of the stomach lining. Intestinal problems such as ulcerative colitis or Crohn’s disease (IBD), diverticulitis, an inflammation and infection of the intestinal wall, IBS (irritable bowel syndrome) which affect movement within the intestines or even cancer are other results.
Similarly nausea and vomiting may be triggered by an adverse reaction to a medication, emotional upset, mild viral infection, ear disorders, migraine headache and motion sickness or even more serious as a heart attack and intestinal obstruction.
