Hiccups can be caused by improper eating habits such as eating irritating or cold food or overeating, which can lead to physiological exhaustion of air into the stomach, and can usually be relieved by drinking warm water and applying heat to the navel. If it is still not effectively relieved, it is necessary to consider the causes of gastric insufficiency, indigestion, gastrointestinal spasm, and gastrointestinal flu, which can also lead to frequent hiccups. Patients can visit a gastroenterology or intestinal clinic to confirm the diagnosis through blood tests, gastroscopy, stool routine and pathogen culture, and then choose probiotics, gastrointestinal motility drugs and antiviral drugs for treatment according to the doctor’s instructions. Chew more when eating, chew slowly and don’t be in too much of a hurry.
