Pollutants And Post Nasal Drip: A Dangerous Link?

Post-nasal drip is when mucus from the nose or sinuses drips down the back of the throat. It can be caused by a variety of factors, including viral and bacterial infections, allergies, irritants in the air, and certain medications. While post-nasal drip is usually not dangerous, it can be annoying and uncomfortable. In some cases, it can lead to a chronic cough or other complications. It is important to see a doctor if you experience persistent or severe symptoms, or if your post-nasal drip does not improve with home remedies and over-the-counter treatments.

Pollutants like smoke and fumes can cause post-nasal drip

Post-nasal drip is a common diagnosis that can be caused by a variety of factors, including pollutants like smoke and fumes.

Post-nasal drip occurs when the body produces more mucus than usual, or the mucus is thicker than normal. This excess mucus then drips down the back of your throat, causing an uncomfortable, tickly feeling.

Mucus is a thick, wet substance that is produced by the glands in the linings of your nose, throat, airways, stomach, and intestinal tract. It is an important part of the body's defence system, trapping and destroying foreign invaders like bacteria and viruses before they can cause infection.

While mucus is typically produced and swallowed without you noticing, certain irritants can cause the body to produce too much of it, or for it to become thicker and more noticeable.

Smoke and fumes are among the common irritants that can cause this excess mucus production and lead to post-nasal drip. Other irritants include dust, strong perfumes, cleaning products, and other environmental pollutants.

People who smoke are more likely to experience post-nasal drip. The cilia, or small hairs, in the lining of the nose help to propel mucus toward the back of the nose for clearing. However, smoke can stunt the cilia's ability to function properly, causing the mucus to become very thick and triggering post-nasal drip.

In addition to smoke, exposure to fumes can also lead to post-nasal drip. Fumes from chemicals, perfumes, cleaning products, and other irritants can cause inflammation or swelling of the lining of the nose, leading to overproduction of mucus.

If you are experiencing post-nasal drip due to exposure to smoke or fumes, there are several treatment options available. Over-the-counter medications such as antihistamines and decongestants can help dry out or thin the mucus, providing relief from the uncomfortable symptoms of post-nasal drip.

Home remedies can also be effective in managing post-nasal drip. These include drinking plenty of fluids to thin the mucus, using a humidifier or steam inhalation, and sleeping with your head elevated to prevent the mucus from pooling at the back of your throat.

While post-nasal drip is typically more of an annoyance than a serious health threat, it is important to consult a doctor if your symptoms persist or are accompanied by other concerning signs, such as bloody or discoloured mucus, shortness of breath, or a high fever.

Post-nasal drip can be caused by viral infections like the common cold

Post-nasal drip is the drainage of mucus from the nose or sinuses into the throat. It is usually caused by the body producing more mucus than usual, or thicker mucus. This excess mucus can be caused by viral infections, such as the common cold, or by other factors such as allergies, sinus infections, or irritants in the air like dust or smoke.

Viral infections like the common cold often cause inflammation or swelling of the nasal passages, leading to a build-up of mucus. This excess mucus then drips down the back of the nose and throat, resulting in post-nasal drip.

Post-nasal drip caused by viral infections like the common cold can be treated with over-the-counter (OTC) medications such as antihistamines and decongestants. Steroid nasal sprays can also be effective in reducing inflammation and mucus production. In addition, there are several home remedies that can help manage symptoms, including:

• Drinking plenty of fluids to thin out mucus and keep it flowing smoothly.
• Using a humidifier or steam inhalation to add moisture to the air and help thin out mucus.
• Propping up pillows while sleeping to prevent mucus from collecting at the back of the throat.
• Nasal irrigation using a neti pot or saline solution to flush out mucus and irritants from the sinuses.

Allergies can cause post-nasal drip

Allergic post-nasal drip is often accompanied by symptoms like sneezing, an itchy nose, and teary/itchy eyes. It is also a seasonal condition that most commonly affects children and young adults.

The body's reaction to allergens involves producing more mucus to flush out the invading particles. While this is a healthy response, it can be uncomfortable.

Allergies are not the only cause of post-nasal drip. It can also be caused by a sinus infection, the common cold, the flu, or a number of other factors. These include changes in weather, certain foods, and exposure to irritants like smoke or chemical fumes.

If you are experiencing post-nasal drip, there are a variety of over-the-counter medications and at-home remedies that can help you find relief.

Bacterial infections can cause post-nasal drip

Bacterial sinusitis is a bacterial infection of the paranasal sinuses, the hollow spaces in the bones of the face around the nose. It involves inflammation of the mucous membrane lining of the sinuses and is caused by a bacterial infection. Bacterial sinusitis often follows a viral infection, such as a cold or the flu.

Symptoms of bacterial sinusitis include:

• Pressure or pain around the nose, in the forehead, in the cheeks, or around the eyes.
• Discolored, thick nasal discharge.
• Decreased sense of smell and ability to taste.
• Coughing or sore throat.
• Post-nasal drip (mucus dripping down the back of the throat).
• Ear pain or a feeling of fullness in the ears.

Bacterial sinusitis may be treated with anti-inflammatory medications and antibiotics if needed. Most cases of bacterial sinusitis resolve within two weeks and have no further symptoms. However, if you have had symptoms for more than 10 days, or if your symptoms are worsening, you should see a doctor.

In addition to bacterial sinusitis, other bacterial infections that can cause post-nasal drip include acute bacterial rhinosinusitis (ABRS), an infection of both the nasal cavity and sinuses caused by bacteria such as Streptococcus pneumoniae and Haemophilus influenzae. Like bacterial sinusitis, ABRS often follows a viral infection. Symptoms of ABRS can include:

• Face pain or pressure that’s worse when leaning forward.
• Pain in the upper jaw.
• Toothache in the upper jaw.
• Yellow or greenish discharge from the nose.
• Ear pressure or fullness.

Like bacterial sinusitis, ABRS can be treated with antibiotics to kill the infecting bacteria. Rinsing the nasal passages with saline can also help.

To prevent post-nasal drip caused by bacterial infections, it is important to take steps to prevent the spread of colds, the flu, and other viral infections. This may include frequent handwashing, getting recommended vaccines, and avoiding irritants such as cigarette smoke.

Deviated septum can cause post-nasal drip

Post-nasal drip is the drainage of mucus from your nose or sinuses into your pharynx, or throat. It is a common symptom of colds, allergies, and infections. A deviated septum can cause post-nasal drip.

The septum is the wall of cartilage and bone that separates your two nostrils. Ideally, the wall is straight and divides your nose into two equally-sized nostrils. However, in most people, it is somewhat crooked or off-centre (deviated). While this condition is not usually severe enough to cause problems, it can interfere with breathing and cause ongoing congestion and sinus infections.

A deviated septum can cause the mucus to build up and thicken. It may feel as though the mucus is dripping down the back of your nose or accumulating in your throat. This is post-nasal drip.

The deviation in the septum can lead to turbulence in the regular airflow, making breathing a difficult and laborious process. There is also an increase in the resistance of the intake of airflow, adding complications to the breathing process. Septum deviations can lead to chronic feelings of nasal congestion. Alterations in the airflow intake patterns lead to excessive mucus production, further narrowing the nasal passages. These developments can make a person feel highly congested and stuffed, worsening breathing difficulties and causing hindrances in daily functioning.

The blockage of sinus drainage pathways results in stagnant mucus collection, which increases the vulnerability to bacterial growth and infections. The inflammation of tissues can also result in excessive mucus production, which causes more congestion. Being prone to recurring sinus infections can have other damaging consequences that degrade one's health. This includes the development or worsening of depressive symptoms, sleep disturbances, the onset of asthma, pneumonia, and degraded ear and brain health.

If you are experiencing post-nasal drip, there are several treatments you can try. Home remedies include drinking fluids, inhaling steam, and sleeping with your head elevated. Over-the-counter medications such as decongestants, antihistamines, and steroid nasal sprays can also help relieve symptoms. If these treatments are ineffective, you may need a prescription medication or surgery to correct your septum.
