The symptoms of diarrhea can occur when the organism is overstressed. Because the gastrointestinal tract of the body is a very sensitive organ, when it is overstressed, the nerve function regulating the stomach will be disturbed, causing abnormal contraction of the muscles of the gastrointestinal tract, resulting in diarrhea and soft or thin stools. In addition, paroxysmal pain around the umbilicus may occur. Stress and diarrhea are functional disorders and do not involve organic lesions, so do not worry too much. The symptoms usually disappear when the nervousness is relieved. When the symptoms are relatively mild, it is recommended to relieve on your own. If the diarrhea symptoms are more serious, it is recommended to take medication to stop the diarrhea. Also, in daily life, it is important to reduce stress and regulate the mental state to prevent the nerves from being in an overly tense state. If the symptoms of diarrhea are not relieved after the psychological state is restored to normal, it is recommended to go to the hospital for examination to exclude the possibility of organic lesions.
