Neurogenic belching, in clinical terms, is also called gastrointestinal dysfunction. This disease is mainly related to bad habits, such as frequent overeating, emotional anxiety, mental stress and so on. In addition, it may also be caused by the human body being infected by Helicobacter pylori. 1. Overeating: If patients often overeat and eat too fast, this will lead to insufficient absorption of food in the gastrointestinal tract, and a large amount of gas will enter the abdominal cavity when eating, which will lead to the symptom of neurogenic belching. 2. Emotional anxiety, mental stress: If the patient is often anxious, mental stress is relatively large, adverse emotions will stimulate the cerebral cortex causing hypothalamic dysfunction. This will make the parasympathetic nerves overexcited, resulting in gastrointestinal peristalsis accelerated, gastric juice secretion rose, which is prone to neurogenic belching. 3. Helicobacter pylori infection: After being infected by Helicobacter pylori, it stimulates the gastrointestinal mucosa, causing gastrointestinal dysfunction and weakening of the digestive ability, so it is easy to have the symptom of nervous belching. It is recommended that patients with neurogenic belching pay attention to chewing and swallowing slowly when eating, maintaining emotional stability, and relaxing moderately. If there is Helicobacter pylori infection, it is necessary to promptly standardize the treatment under the guidance of the doctor.
