What causes a persistent cough with white phlegm and an itchy throat, and what should be done?
Generally speaking, the throat refers to the pharynx. Prolonged coughing with white phlegm and a sore throat may be related to environmental irritants, improper diet, dry throat, bronchitis, allergic rhinitis, and other factors. It is recommended to seek timely medical attention and follow the guidance of a physician for treatments such as general therapy or medication. A detailed explanation is as follows:
1. Environmental Irritation
Remaining in a dry, dusty environment for a prolonged period can irritate respiratory mucosa, causing coughing, a sore throat, and white phlegm. It is recommended to maintain fresh indoor air and wear a mask when going outdoors to reduce inhalation of harmful substances.
2. Improper Diet
Consuming excessive spicy, greasy, or cold foods or drinking alcohol in large quantities can irritate the throat mucosa, leading to coughing and throat discomfort, which may easily induce the production of white phlegm. It is recommended to adjust dietary habits and avoid excessive intake of irritating foods and alcohol.
3. Dry Throat
When the throat is dry, the mucosa loses moisture, causing throat itching and coughing, which may also result in the production of white phlegm. It is recommended to drink more water to keep the respiratory tract moist and prevent throat dryness.
4. Bronchitis
Bronchitis is commonly triggered by viral or bacterial infections. Inflammation stimulates the bronchial mucosa and surrounding nerves, causing throat itching and coughing, with increased mucus secretion in the throat, resulting in white sticky phlegm. It is usually accompanied by symptoms such as fever, chills, and headache. Follow medical advice for treatment with medications such as Levofloxacin Hydrochloride Tablets, Cefixime Capsules, and Compound Methoxyphenamine Capsules.
5. Allergic Rhinitis
Allergic rhinitis is typically caused by allergens such as pollen or house dust mites irritating the nasal mucosa. The rhinitis leads to excessive nasal discharge, which flows backward into the throat, causing coughing and white phlegm, while also stimulating nerve endings, resulting in throat itching. It is generally accompanied by symptoms such as nasal itching, paroxysmal sneezing, and nasal congestion. Follow medical advice for treatment with medications such as Azelastine Fluticasone Nasal Spray, Budesonide Nasal Spray, and Triamcinolone Acetonide Acetate Cream.
Maintain a clean environment in daily life, regularly open windows for ventilation, and avoid staying in enclosed, polluted environments for long periods to prevent symptoms such as coughing and throat itching.
