Why does phlegm come out when I massage my throat, and what should I do about it?

Generally, the expulsion of phlegm upon massaging the throat may be caused by normal swallowing reflex stimulation, coordinated action of respiratory cilia, chronic pharyngitis, bronchitis, pneumonia, or other reasons. Treatment options include general therapy and medication under a doctor's guidance. If discomfort occurs, prompt medical attention is recommended. Detailed analysis is as follows:

1. Normal Swallowing Reflex Stimulation

The human throat contains a swallowing reflex mechanism. When massaging the throat, stimulation of the surrounding muscles and nerves may trigger a mild swallowing reflex. During this reflex process, the muscles in the throat and related areas contract in coordination, pushing any small amount of phlegm present in the throat, making it easier to expel. It is recommended to maintain oral hygiene, rinse the mouth promptly after meals, reduce residual food particles in the oral and throat areas, and avoid excessive secretions caused by irritation.

2. Coordinated Action of Respiratory Cilia

Cilia are present on the respiratory mucosa; these cilia rhythmically move and can transport dust, bacteria, and secretions in the respiratory tract toward the throat. Throat massage may, to some extent, enhance the coordination of ciliary movement, accelerating the expulsion of phlegm toward the throat. It is recommended to avoid prolonged exposure to heavily polluted air, reduce outdoor activities during haze weather, and wear protective masks when going out if necessary.

3. Chronic Pharyngitis

Chronic pharyngitis is usually caused by smoking, air pollution, or infections. Chronic pharyngitis leads to congestion of the throat mucosa and increased secretions. Phlegm expulsion may be triggered by irritation of the mucosa during massage, possibly accompanied by symptoms such as a foreign body sensation and throat discomfort. Treatment options include medications such as Pharyngitis Tablets, Amoxicillin Capsules, and Shuanghuanglian Oral Liquid, under medical guidance.

4. Bronchitis

Bronchitis is mainly caused by viral infections, bacterial infections, cold air, dust, or irritating gases. When bronchial inflammation occurs, goblet cells and mucus glands in the bronchial mucosa proliferate and enlarge, secreting large amounts of mucus that form phlegm. When massaging the throat, due to the interconnected nature of the throat and bronchi within the respiratory system, phlegm in the bronchi may move toward the throat and be expelled under the influence of respiratory airflow and throat muscle movements. Symptoms may also include dry cough, wheezing, and shortness of breath. Medications such as Ambroxol Hydrochloride Oral Solution, Theophylline Sustained-Release Tablets, and Roxithromycin Tablets may be used under medical guidance.

5. Pneumonia

Pneumonia is generally caused by age-related factors, smoking, low immunity, bacterial infection, viral infection, or other reasons. When lung inflammation occurs, exudates are produced in the inflamed alveoli and bronchi, which mix together to form phlegm. During throat massage, with changes in respiratory movements and body posture, phlegm from the lungs may move upward along the bronchi and be expelled through the throat. Symptoms may include high fever, cough, and expectoration. Medications such as Azithromycin Tablets, Cefixime Dispersible Tablets, and Feilikhe Mixture may be used under medical guidance.

It is recommended to reduce irritating factors such as smoking, alcohol consumption, and exposure to harmful gases in daily life to protect respiratory health.
