Why is there an excessive amount of white phlegm in the throat that seems impossible to completely cough up, and what should be done?

Normally, the presence of excessive white phlegm in the throat that seems difficult to expel completely may be caused by environmental irritants, improper diet, chronic pharyngitis, chronic bronchitis, bronchiectasis, or other related factors. Treatment options include general management and medication under a doctor's guidance. If discomfort occurs, timely medical consultation is recommended. A detailed explanation is as follows:

1. Environmental Irritants

When exposed to environments with heavy dust pollution, high levels of chemical volatilization, or excessive air humidity, the respiratory mucosa may become irritated. This irritation can stimulate increased mucus secretion as a protective response. The mucus combines with inhaled impurities to form white phlegm, leading to persistent phlegm discharge from the throat. It is advisable to avoid such adverse environments as much as possible, for example, by wearing a protective mask on hazy or heavily polluted days and maintaining fresh indoor air.

2. Improper Diet

Excessive consumption of raw, cold, greasy, or overly sweet foods may impair normal spleen and stomach function, causing disturbances in the body's metabolism of fluids and leading to the formation of dampness and phlegm. This phlegm may accumulate in the throat, resulting in continuous white phlegm discharge. A balanced diet should be maintained, with reduced intake of such foods and increased consumption of vegetables, fruits, whole grains, and other foods rich in dietary fiber.

3. Chronic Pharyngitis

Chronic pharyngitis typically arises from repeated episodes of acute pharyngitis, long-term irritation from smoking and alcohol consumption, or inhalation of harmful gases. It may lead to congestion and swelling of the throat mucosa, increased mucus secretion, and persistent white phlegm in the throat. Symptoms such as coughing, hoarseness, and sore throat may also be present. Medications such as Pharyngitis Tablets, Cetylpyridinium Iodide Lozenges, and Amoxicillin Capsules may be used under medical guidance for treatment.

4. Chronic Bronchitis

Chronic bronchitis is generally caused by infectious or non-infectious factors. It may lead to increased mucus secretion from the bronchial mucosa, resulting in excessive white phlegm in the throat that is difficult to fully expel. Symptoms such as coughing, wheezing, and shortness of breath may also occur. It is recommended to follow medical advice and use medications such as Dextromethorphan Oral Solution, Ambroxol Hydrochloride Oral Solution, and Cefradine Capsules for treatment.

5. Bronchiectasis

Bronchiectasis is mainly associated with genetic disorders, infections, immune deficiencies, ciliary abnormalities, and foreign body inhalation. These factors can lead to increased bronchial secretions and excessive white phlegm in the throat. Symptoms such as coughing, difficulty breathing, and chest pain may also occur. Treatment under medical supervision with medications such as Carbocisteine Oral Solution, Salbutamol Aerosol, and Levofloxacin Hydrochloride Capsules is recommended.

In daily life, it is important to engage in moderate physical activities, such as walking or yoga, to enhance immune function. Attention should be paid to weather changes, and clothing should be adjusted promptly to prevent the respiratory tract from exposure to cold air. Good sleep habits should be developed, ensuring sufficient sleep to support the normal recovery and regulation of bodily organs.
