The causes of hiccups and flatulence at night include gastrointestinal dysfunction and gastritis, which need to be actively treated. 1. Gastrointestinal dysfunction: When overeating and eating too much greasy food, due to the slowing down of gastrointestinal peristalsis at night, gastrointestinal dysfunction may occur, manifested as hiccups and flatulence. It is recommended to avoid overeating in life, less oil and salt, avoid overfilling, quit smoking and drinking, and exercise reasonably after meals. 2. Gastritis: the vagus nerve is more excited at night, and the gastrointestinal mucosa is more sensitive to the stimulation of inflammatory reaction, so the symptoms of hiccups and flatulence are more obvious at night. You can take drugs to protect the gastric mucosa such as magnesium aluminum carbonate, misoprostol, etc., regulate gastrointestinal dynamics such as domperidone, cisapride, trimethoprim maleate, etc., and inhibit the secretion of gastric acid drugs such as omeprazole, ranitidine, etc. to improve the symptoms. When night burping and flatulence occurs, it is recommended to go to the hospital in time to clarify the cause of the disease, and actively cooperate with the doctor to receive treatment to relieve the discomfort and improve the symptoms through treatment. Drugs need to be used under the guidance of a doctor, and when there are adverse reactions to the emergence of timely consultation.
