The causes of non-stop hiccups from one day to the next include eating too fast, pyloric spasm, gastrointestinal neurosis, chronic gastritis and so on. 1. Eating too fast: eating too fast, eating too quickly, easy to ingest too much air, causing involuntary contraction of the diaphragm, resulting in non-stop hiccups. 2. Pyloric spasm: when the pylorus spasms, air is blocked from being discharged in the stomach, causing involuntary contraction of the diaphragm and hiccups. 3. Gastrointestinal neurosis: In patients with gastrointestinal neurosis, gastrointestinal peristalsis is weakened, causing diaphragmatic spasm and hiccups. 4. Chronic gastritis: chronic gastritis patients with gastrointestinal dysfunction, excessive secretion of gastric acid causing gastric stimulation, as well as gastric emptying obstruction, hiccups can also occur. There are many other reasons that cause hiccups day and night. If the hiccups are not relieved, or accompanied by other symptoms, you should go to the hospital in a timely manner, to identify the cause of the hiccups, and then give targeted treatment.
