The patient hiccups food reflux into the throat, a condition seen in reflux esophagitis or functional gastric disease, because the peristaltic emptying function of the stomach is poor and food containing stomach acid refluxes upward into the esophagus and even into the throat, causing damage to the mucosa of the throat and esophagus, which requires an electronic gastroscopy to clarify. After the diagnosis is confirmed, treatment with mosapride citrate and domperidone plus omeprazole is needed for 3-8 weeks. When you have the above symptoms, avoid overeating, eat less greasy, fried and other hard-to-digest foods, abstain from alcohol, and focus on light foods. If the above symptoms are obvious when the patient sleeps, it is recommended to elevate the foot of the bed slightly on the head side to reduce reflux. Taking a proper walk after a meal is also beneficial to reduce this symptom.
