2. Allergies and Sensitivities
Allergic rhinitis (hay fever) can trigger excess mucus production. Even mild allergies—dust, pet dander, pollen, mold—can cause chronic mucus in the throat.
Symptoms may include:
-
Sneezing and itchy eyes
-
Runny or blocked nose
-
Throat tickle and cough
-
Mucus that is clear or slightly white
What helps: antihistamines, nasal corticosteroid sprays, and reducing exposure to triggers (air purifier, cleaning dust, washing bedding).
3. Sinus Infections and Chronic Sinusitis
When your sinuses are inflamed or infected, mucus can become thicker and drain into your throat. Chronic sinusitis can last weeks or months.
Clues it may be sinus-related:
-
Facial pressure or headache
-
Thick yellow/green mucus
-
Stuffy nose
-
Reduced smell or taste
What helps: warm steam, saline rinses, and medical treatment if symptoms persist or worsen.
