Gastrointestinal neurosis, also known as functional gastrointestinal disorder, primarily arises from psychological factors in the absence of organic diseases. Emotional stress, anxiety, difficulties in life and work, worries, and unexpected misfortunes can all disrupt normal gastrointestinal functions, leading to functional disorders. The treatment of gastrointestinal neurosis fundamentally requires psychological adjustment and behavioral changes. Traditional treatments include dietary therapy, nutritional support, sedatives, antispasmodics, and pain relievers. Depending on the condition, doctors may prescribe intestinal regulators, oryzanol, digestive enzymes, vitamin B1, Gaviscon (a brand name for an antacid), and Motilium (a brand name for a prokinetic agent). For patients with pronounced psychological symptoms, anti-anxiety or antidepressant medications may be administered to help alleviate psychological barriers.
