Phlegm with Nasal-Like Secretions: Causes and Solutions - Otolaryngology

Share to:

Sputum contains substances similar to nasal secretions?


Hello, Doctor.
In the past two years, I have occasionally felt like there is mucus resembling nasal secretions stuck in my throat, and expelling it provides significant relief.
This occurs about 2 to 4 times a day, and it feels different from typical phlegm; it has a more solid, booger-like structure.
Could this be caused by post-nasal drip? (I often experience nasal congestion and post-nasal drip issues.) Should I see an ENT specialist for this mucus problem? Thank you, Doctor.

Hello: Common issues that may be related to post-nasal drip include excessive or foul-smelling secretions.
It is advisable to visit an otolaryngologist to check for conditions such as sinusitis or other related problems.
Wishing you safety and health.

More Info


The symptoms you are experiencing, particularly the sensation of phlegm that resembles nasal secretions in your throat, are indeed suggestive of post-nasal drip, which is a common condition associated with nasal congestion and sinus issues. Post-nasal drip occurs when excess mucus accumulates in the nasal passages and drips down the back of the throat, leading to discomfort and the feeling of needing to clear your throat frequently.


Causes of Post-Nasal Drip
1. Allergic Rhinitis: Allergies can lead to inflammation of the nasal passages, causing increased mucus production. Common allergens include pollen, dust mites, pet dander, and mold.

2. Sinusitis: Chronic sinusitis can result in thickened mucus that may not drain properly, leading to a sensation of mucus accumulation in the throat.

3. Infections: Viral or bacterial infections can cause increased mucus production. A cold or flu can lead to temporary post-nasal drip.

4. Environmental Irritants: Exposure to smoke, strong odors, or pollutants can irritate the nasal passages and lead to increased mucus production.

5. Structural Issues: Conditions such as a deviated septum or nasal polyps can obstruct normal mucus drainage, contributing to post-nasal drip.


Symptoms Associated with Post-Nasal Drip
- A sensation of mucus in the throat
- Frequent throat clearing
- Coughing, especially at night
- Sore throat
- Bad breath
- Nasal congestion or blockage

Management and Treatment Options
1. Nasal Irrigation: Using a saline nasal spray or a neti pot can help clear mucus from the nasal passages and reduce post-nasal drip.

2. Hydration: Staying well-hydrated can thin mucus, making it easier to expel.

3. Antihistamines: If allergies are the cause, over-the-counter antihistamines can help reduce mucus production and alleviate symptoms.

4. Decongestants: These can help reduce nasal swelling and improve drainage, but they should be used cautiously and not for extended periods.

5. Steam Inhalation: Inhaling steam can help loosen mucus and soothe irritated nasal passages.

6. Avoiding Irritants: Reducing exposure to known allergens and irritants can help manage symptoms.


When to See a Doctor
Given your symptoms of nasal congestion and the sensation of phlegm resembling nasal secretions, it would be advisable to consult an Ear, Nose, and Throat (ENT) specialist. They can perform a thorough examination, which may include:
- Nasal Endoscopy: This allows the doctor to visualize the nasal passages and sinuses directly.

- Imaging Studies: A CT scan may be necessary to assess for sinusitis or structural abnormalities.

- Allergy Testing: If allergies are suspected, testing can help identify specific triggers.

In conclusion, while post-nasal drip is a common condition, it can significantly affect your quality of life. Identifying the underlying cause is crucial for effective treatment. Consulting with an ENT specialist will provide you with a tailored approach to manage your symptoms and improve your overall well-being.
