Persistent Phlegm in Throat: Causes and When to Seek Help

Inability to expel phlegm?

Since around the sixth grade, I have felt like there is phlegm in my throat that I can't expel.
During this time, when I catch a cold, I do produce phlegm, but sometimes it comes out when I cough, while that persistent sensation remains.
I usually don't pay much attention to it, but occasionally when I try to swallow, it feels very uncomfortable.
What could this be? This has been bothering me for about seven years.
Around the same time, I also noticed that when I swallow saliva, I hear a sound in my ears that is hard to describe; it sounds somewhat like static or a popping noise.
Would you recommend that I get this checked?

Dear Xiao Xuan,
Hello, the sensation of phlegm or a foreign body in the throat is often caused by chronic pharyngitis, which may be related to smoking, air pollution, gastroesophageal reflux, or post-nasal drip.
The unusual sound in the ears when swallowing saliva could indicate an issue with the Eustachian tube.
It is advisable to seek medical attention for a thorough examination by a physician to identify the underlying problem.
Wishing you safety and health,
Dr.

More Info

Persistent phlegm in the throat can be a frustrating and uncomfortable condition, especially when it has been ongoing for several years. The sensation of having phlegm that you cannot clear can be caused by a variety of factors, and understanding these can help you determine the best course of action.

One common cause of persistent phlegm is post-nasal drip, which occurs when mucus from the nasal passages drips down the back of the throat. This can happen due to allergies, sinus infections, or even irritants in the environment such as smoke or pollution. When the body detects irritants, it produces more mucus as a defense mechanism, leading to the sensation of phlegm in the throat.

Another potential cause could be gastroesophageal reflux disease (GERD), where stomach acid flows back into the esophagus, irritating the throat and causing a sensation of mucus or phlegm. This can also lead to a chronic cough or the feeling of something stuck in the throat.

Chronic bronchitis or other respiratory conditions can also contribute to the feeling of persistent phlegm. In these cases, the lungs produce excess mucus, which can lead to coughing and discomfort in the throat.

Given that you have experienced this sensation for about seven years, it is advisable to seek medical attention. A healthcare professional can perform a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly imaging studies or allergy testing. They may also refer you to an ear, nose, and throat (ENT) specialist if necessary.

In addition to seeking medical advice, there are some self-care strategies you can consider. Staying hydrated can help thin mucus, making it easier to clear. Using a humidifier in your home can also add moisture to the air, which may alleviate throat discomfort. Avoiding known irritants, such as smoke or strong odors, can help reduce symptoms.

If allergies are suspected, over-the-counter antihistamines may provide relief. However, it is essential to consult with a healthcare provider before starting any new medication, especially if you have other underlying health conditions.

In summary, persistent phlegm in the throat can stem from various causes, including post-nasal drip, GERD, or chronic respiratory conditions. Given the duration of your symptoms, it would be wise to consult a healthcare professional for a proper diagnosis and treatment plan. Taking proactive steps to address this issue can significantly improve your quality of life and alleviate discomfort.
