Phlegm is a type of mucus that is formed in the chest.  A noticeable amount of phlegm in varying consistency is formed when there is an infection or disease affecting the lungs, throat, or nose (1,2).

The consistency of mucus can range from mucoid (frothy) to mucopurulent to purulent (thick and sticky).  According to the type and severity of the infection, the phlegm may get darker and thicker (3).

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

Mucus can change into different colors depending on the type of infection affecting your lungs.

Phlegm may change colors according to infections such as (4,5,6):

  • Green Or Yellow: Bronchitis, Cystic Fibrosis, Pneumonia or Sinusitis.
  • Brown: Bronchitis, Cystic Fibrosis, Lung Abscess, Pneumonia or Pneumoconiosis.
  • White: Bronchitis, Chronic Obstructive Pulmonary Disease (COPD), Congestive Heart Failure Or Gastroesophageal Reflux Disease (GERD).
  • Black: Fungal Infection, Lung Abscess, Pneumoconiosis or Smoking.
  • Clear: Allergic Rhinitis, Bronchitis Or Pneumonia
  • Red Or Pink: Congestive Heart Failure, Lung Abscess, Lung Cancer, Pneumonia, Pulmonary Embolism, Tuberculosis

Why Are You Coughing Up Brown Mucus Or Phlegm?

Mucus is a slippery liquid made by mucous membranes or mucosas.

Mucus or phlegm is a very important material which 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 (7,8,9).

Coughing up phlegm commonly happens when one is suffering from common cold or flu. It is normal and nothing so alarming about it.  

But if you are coughing up thick brown mucus it would mean that you are suffering from infections or disease affecting your lungs (10).

Usually, brown phlegm (bflem) 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.  

Brown phlegm is commonly caused by:

1. Lung Infections

Lung infection caused by bacteria or viruses are the main reason for phlegm changing color to brown. Respiratory infections occur when a bacterium or virus is trapped in your nasal cavity (11,12).

Here are some of the common infections that may cause brown mucus discharge while coughing:

  • Bacterial bronchitis: Acute or chronic bronchitis can produce rusty brown sputum. Smoking or continuous exposure to chemical fumes and 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 sputum 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 sputum.

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 brown 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 make the phlegm appear dark brown.

The side effects of smoking also result in chronic bronchitis and emphysema which has brown mucus as one of the symptoms.

4. Environmental Pollutants

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

Industrial labors and factory workers who have to work in dusty surrounding might end up coughing up brown mucus.

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

5. Nasal Polyps

Nasal polyps are painless, noncancerous growths that can lead to a lost sense of smell or infection (13,14).

The nose bleeding caused by Nasal polyps may make the patient’s mucus to become brown or red in color. The dried blood in sinus gets mixed with the phlegm to change its color to brown.Reasons For Coughing Up Brown Phlegm
