Hiccups do not cause hiccups, but hiccups can lead to episodes of phlegm. This is a clinical manifestation of chronic pharyngitis, mainly due to diffuse mucosal congestion, edema, and lymphatic follicular hyperplasia in the throat, which leads to a foreign body sensation in the throat when the hyperplastic lymphatic follicles rub against the epiglottis. and gastrointestinal dysfunction, leading to acid reflux, sour water, and the stimulation of acid gas. For treatment, patients need to eat a light diet, avoid spicy and stimulating foods, stop smoking and drinking, and adjust gastrointestinal function to avoid acid reflux and hiccups. Oral loxacillin or morpholine can be used to suppress acid and increase gastrointestinal motility. If necessary, gastroscopy can be performed, and patients should also take oral lorazepam and diphenhydramine pellets to relieve throat symptoms.
