Breathing with the mouth closed, an abnormal sound from the throat can be heard.

In general, hearing abnormal sounds in the throat during closed-mouth breathing may be caused by increased phlegm, foreign body irritation, pharyngitis, glottic fissure, vocal cord polyps, or other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Increased Phlegm

If one frequently consumes greasy or overly sweet foods, it may lead to excessive phlegm production. During closed-mouth breathing, airflow may pass through the accumulated phlegm, causing unusual noises. It is advisable to drink more water regularly to help dilute the phlegm and alleviate symptoms.

2. Foreign Body Irritation

If a foreign object is accidentally swallowed and becomes lodged in the throat, it may cause abnormal sounds during breathing due to air passing around the obstruction. Prompt medical evaluation is recommended for safe removal of the foreign body under professional supervision.

3. Pharyngitis

Bacterial infections can lead to pharyngitis, resulting in mucosal swelling and increased secretions, which may increase airway resistance and produce abnormal throat sounds during breathing. Under medical guidance, medications such as compound Honeysuckle granules, amoxicillin capsules, or roxithromycin tablets may be used for treatment.

4. Glottic Fissure

A glottic fissure refers to a gap between the vocal folds, which may result from congenital conditions or trauma. If present, air passing through this gap during respiration can generate abnormal throat sounds. Timely medical consultation is advised, with possible surgical closure performed under medical supervision.

5. Vocal Cord Polyps

Vocal cord polyps, often caused by chronic irritation or inflammation, may interfere with normal vocal cord movement, leading to audible throat sounds during closed-mouth breathing. Under medical guidance, surgical removal of the polyp may be recommended to promote recovery.

Maintaining healthy lifestyle habits is important. Avoid consuming spicy and irritating foods such as Sichuan pepper, chili peppers, and garlic, as these may hinder recovery.
