What should I do about postnasal drip and excessive throat mucus caused by sinusitis?

Sinusitis is an inflammation of the sinuses. When the sinuses become infected, inflamed, or affected by allergic reactions, the sinus mucosa swells and produces excessive mucus. Postnasal drip and excessive throat phlegm caused by sinusitis can be managed through maintaining good hydration habits, avoiding irritants and allergens, saline rinses, maintaining a moist environment, and medication therapy. Specific approaches are as follows:

1. Maintain good hydration habits: Increasing fluid intake helps thin mucus, making it easier to expel. Drinking sufficient water or other non-caffeinated beverages, especially warm water or hot tea, helps improve hydration levels in the body.

2. Avoid irritants and allergens: Minimize exposure to irritants and allergens such as smoke, dust, air pollutants, and pollen. These substances may worsen symptoms of sinusitis.

3. Saline rinses: Using warm saline solution or nasal irrigation solutions to rinse the nasal passages helps clear the sinuses and reduce mucus buildup. This can alleviate sinusitis symptoms and thereby reduce postnasal drip and excessive phlegm.

4. Maintain a moist environment: Keeping the throat and nasal passages moist helps reduce discomfort and inflammation. A humidifier can be used to increase indoor humidity, or steam inhalation can be performed, allowing moisture in the air to soothe irritation in the throat and nasal areas.

5. Medication therapy: The above measures typically address symptoms associated with sinusitis. Under medical guidance, medications such as roxithromycin tablets or cefalexin for oral suspension may be used for treatment.

If symptoms are severe or do not improve, consult a doctor promptly for an accurate diagnosis and further treatment recommendations.
