Coughing Up Brown Mucus – 5 Causes And Simple Remedies

All of a sudden, coughing up brown mucus may make you feel anxious and worried about your lungs’ health.

Normally, the body produces mucus to keep the respiratory tract moist. It helps to trap and force out the small particles of foreign matter that may harm the lungs.

The body produces mucus to keep the thin, delicate tissues of the respiratory tract moist so that small particles of foreign matter that may pose a threat can be trapped and forced out.

Phlegm Consistency And Colors

Phlegm is a type of mucus that is formed in the chest. A noticeable amount of phlegm in varying degrees of consistency is formed when infection or disease is affecting the lungs, throat, respiratory tract, or nose.

The consistency of phlegm can range from mucoid (frothy) to mucopurulent (thick and sticky). It may get darker and thicker according to the type and severity of the infection.

The color comes from white blood cells.

When you are dehydrated or in the morning, it usually becomes thick and dark.

It can change colors depending on the type of infection affecting your lungs. For example, black lung disease (mostly found in coal miners), may cause black sputum.

The phlegm colors may change according to viral or bacterial infections, such as:

Yellow or Green Phlegm: Bronchitis, Cystic Fibrosis, Pneumonia, or Sinusitis.

Brown Phlegm: Bronchitis, Cystic Fibrosis, Lung Abscess, Pneumonia, or Pneumoconiosis.

White Phlegm: Bronchitis, Chronic Obstructive Pulmonary Disease (COPD), Congestive Heart Failure, or Gastroesophageal Reflux Disease (GERD).

Black Phlegm: Fungal Infection, Lung Abscess, Pneumoconiosis, or Smoking.

Clear Phlegm: Allergic Rhinitis, Bronchitis, Or Pneumonia.

Red Or Pink Phlegm: Congestive Heart Failure, Lung Abscess, Lung Cancer, Pneumonia, Pulmonary Embolism, Tuberculosis.

Why Are You Coughing Up Brown Mucus?

A mucus is a slippery liquid made by mucous membranes or mucosas.

Phlegm means a type of mucus that comes from the lungs and nearby lower respiratory airways.

This thick fluid has several beneficial functions for health. It helps trap particles such as dirt, minimizes water loss, protects the surface from damage, lubricates, and most importantly, destroys bacteria and viruses.

Coughing up phlegm may happen when one is suffering from a common cold or flu. It is normal, and there is nothing alarming about it.

But if you are coughing up a thick brown or chocolate-colored mucus, it would mean that you are suffering from infections or diseases affecting your lungs.

Usually, it is not an indication of any serious underlying health conditions. However, you should be vigilant in consulting a physician if the issue persists for more than a day.

Coughing Up Brown Phlegm

This condition is commonly caused by:

1. Lung Infections

Lung infection caused by bacteria or viruses is the main reason phlegm changes color to brown. Respiratory infections occur when a bacterium or virus is trapped in your nasal cavity.

Generally, bacteria can cause black phlegm when secondary bacterial infection occurs in your lungs due to a weakened immune system.

Here are some of the common infections that may cause it to be discharged while coughing:

Bacterial bronchitis: Acute or chronic bronchitis can produce rusty brown sputum. Smoking or continuous exposure to chemical fumes or other irritants can aggravate the situation.

Bacterial pneumonia: Brown or rusty-colored mucus is one of the symptoms of bacterial pneumonia.

Lung abscess: People suffering from lung abscess may experience a cough that brings up brown or blood-streaked sputum with a foul smell.

Pneumoconiosis: Discharge of brown fluid while coughing is one of the symptoms of Pneumoconiosis which is caused by regularly inhaling dust from coal, silicosis, asbestos, or other dust pollutants.

Cystic fibrosis: This chronic lung disease may cause rust-colored spittle.

2. Acid Reflux

Stomach acid or bile flowing back up into your esophagus is a common acid reflux issue faced by many.

GERD is a chronic form of acid reflux that can irritate the lining of your esophagus, causing it to become inflamed. This may also result in the development of mucus in the esophagus.

The phlegm can also become brownish when you regurgitate food, especially after you consume coffee, chocolate, or red wine.

3. Smoking

Throwing up rust-colored phlegm while coughing can also be the result of heavy smoking.

Smokers accumulate a combination of resins, tar, and nicotine in the lungs and bronchial passages, which makes the phlegm appear dark brown.

The side effects of smoking also result in chronic bronchitis and emphysema, which have brownish or rust-colored mucus as one of the symptoms.

4. Environmental Pollutants

A person living or working in a highly polluted environment may change the color of their sputum to dark brown or black.

Industrial laborers and factory workers who have to work in dusty surroundings might end up coughing up dark mucus.

After cleaning an extremely dusty room, you may discharge brown bile while coughing.

5. Nasal Polyps

Nasal polyps are painless, noncancerous growths that can lead to a loss of smell or infection.

The nose bleeding caused by nasal polyps may make the patient’s mucus brown or red in color. The dried blood in the sinus gets mixed with the phlegm to change its color to brown.

Coughing Up Dark Mucus After Quitting Smoking

Many smokers experience coughing up black mucus after quitting smoking. Yes, this may happen for a few more weeks after totally quitting smoking.

There are tiny hair-like projections on the surface of the airways called Cilia which help in clearing mucus and debris from the lungs.

Smoking tobacco damages the cilia, which results in the aggregation of mucus and debris in the lungs.

Cilia gradually regain function a week after quitting smoking, but it may take a few months for Cilia to regenerate to its actual status.

So it is natural that smokers continue to cough up brown mucus after quitting smoking for a couple of weeks more till the damaged cilia are fully regrown.
