Gastrointestinal dysfunction is a general term for a group of gastrointestinal syndromes, mostly with a psychiatric background, with a predominance of gastrointestinal motility disorders without an organic anatomical basis, and therefore excluding gastrointestinal dysfunctions caused by other systemic diseases. The clinical manifestations are mainly in the gastrointestinal tract involving abnormalities in feeding and excretion, but are also often accompanied by other functional symptoms such as insomnia, anxiety, inattention, amnesia, hypersensitivity, and headache. Gastrointestinal disorders are quite common and there is a lack of precise statistics on their incidence in China. Among the neuroses of various organs, gastrointestinal disorders have the highest number of incidences and are mostly seen in young adults. So how do we treat gastrointestinal dysfunction syndrome? 1.Psychotherapy. It is effective for 2/3 of patients. The key to treating gastrointestinal functional disorders is to release the psychological barriers to adjust the organ function. If the patient suspects or worries that he or she is suffering from a certain disease, the doctor conducts a targeted examination, relieves the doubts and stabilizes the emotions, which is also a treatment means in itself. 2.Supportive therapy. Unless the patient’s general condition is very poor, generally do not need bed rest. Regular life and appropriate physical activities can enhance physical fitness and accelerate the recovery of neurological function. Patients with anorexia nervosa accompanied by severe malnutrition and nasogastric tube feeding and causing diarrhea need intravenous nutrition input. High-fiber food can relieve the symptoms of IBS patients. 3.Medication. Short-term administration of antidepressants has obvious efficacy for patients with psychiatric symptoms.
