Why Is My Mucus Brown is a question many people ask when they notice unusual discoloration in their phlegm or nasal mucus. Brown mucus isn’t the typical clear or white discharge; it can indicate irritation, inflammation, old blood, or debris in the respiratory system. Understanding the potential causes helps you know when to seek medical attention.
Whether you’re seeing brown mucus in the throat, brown mucus from the nose, or coughing up brown mucus, it can be concerning, especially if accompanied by cough or discomfort. At our Eagle Pass emergency room, medical professionals are prepared to evaluate these symptoms and provide the proper treatment or urgent care as needed.
What Does Brown Mucus Mean?
Brown mucus, also called brown phlegm or phlegm with brown flecks, usually indicates that your respiratory system is expelling old blood, tar, debris, or environmental particles. While not diagnostic, it may indicate airway irritation, inflammation, or infection. A study reviewing 5,770 sputum samples found that discolored sputum had 81% sensitivity in indicating bacterial involvement but only 50% specificity, showing color must be interpreted alongside other symptoms.
Brown Mucus Symptoms
- Persistent cough bringing up brown phlegm.
- Brown mucus from the nose or nasal discharge.
- Thick, rubbery mucus from the throat.
- Mucus is brownish-yellow in appearance.
- Brown mucus and a cough that lasts for several days.

What Causes Brown Mucus
Brown mucus often occurs when the respiratory system is irritated, inflamed, or trying to expel particles, blood, or debris. While it indicates a change in airway health, the underlying causes can range from minor irritants to serious conditions. Identifying the cause guides proper treatment and helps prevent complications. Below are some of the most common reasons for brown mucus.
Smoking and Tobacco Exposure
Smoking and exposure to tobacco products can deposit tar, chemicals, and other particles in the lungs. Over time, these substances mix with mucus, producing brown phlegm. Chronic irritation can damage airways and increase mucus production. Morning cough is especially common in long-term smokers.
Symptoms
- Morning brown mucus spit.
- Persistent smoker’s cough.
- Wheezing or shortness of breath.
- Chest tightness.
- Increased mucus production.
Respiratory Infections
Infections such as bronchitis, pneumonia, or the common cold inflame the airways, often leading to coughing up brown mucus. The discoloration may result from oxidized blood, immune cells, and debris. Symptoms vary with infection severity, and prompt treatment can prevent complications.
Symptoms
- Fever and chills.
- Chest pain or discomfort.
- Persistent productive cough.
- Foul-smelling sputum.
- Difficulty breathing.
Chronic Lung Diseases (COPD, Bronchiectasis)
Chronic lung conditions like COPD or bronchiectasis can cause ongoing inflammation and thick mucus production. Repeated infections may lead to brown phlegm. Management usually requires long-term care, and changes in mucus color may indicate infection flare-ups.
Symptoms
- Long-term cough with phlegm.
- Wheezing and shortness of breath.
- Frequent respiratory infections.
- Thick, sticky mucus.
- Fatigue from breathing effort.
Cystic Fibrosis
Cystic fibrosis is a genetic condition that causes thick, sticky mucus buildup in the lungs. Trapped bacteria can lead to infections, producing brown mucus in the throat. Early treatment reduces complications, and airway clearance techniques are often necessary.
Symptoms
- Chronic cough with thick phlegm.
- Recurrent lung infections.
- Poor weight gain.
- Sinus congestion.
- Shortness of breath.
Lung Abscess
A lung abscess is a localized lung infection that produces pus and may cause brown mucus spit. The mucus often has a foul odor due to bacterial activity. Severe cases may require drainage or prolonged antibiotics, making timely medical evaluation essential.
Symptoms
- Foul-smelling phlegm.
- Fever and night sweats.
- Chest pain.
- Fatigue.
- Weight loss.
Environmental Irritant Exposure
Exposure to dust, chemical fumes, or pollution can irritate the respiratory tract, leading to phlegm with brown flecks. The body produces more mucus to trap these irritants, and chronic exposure can worsen airway inflammation. Protective measures can reduce symptoms.
Symptoms
- Cough after irritant exposure.
- Throat irritation.
- Eye irritation.
- Increased mucus production.
- Worsened symptoms in polluted areas.
Nasal Bleeding / Dryness
Minor nosebleeds or dry nasal passages can mix with mucus, resulting in brown colored mucus. Dry climates and frequent nose blowing increase the likelihood. Most cases are mild, but persistent bleeding should be evaluated. Saline sprays can help relieve dryness.
Symptoms
- Brown discharge from nose.
- Dry nasal passages.
- Occasional nosebleeds.
- Post-nasal drip.
- Scratchy throat.
Acid Reflux (GERD)
Acid reflux can irritate the throat and airways, causing brown mucus in the throat, especially in the mornings. Stomach acid triggers inflammation and mucus production. Controlling reflux can reduce mucus discoloration, and lifestyle changes or medications are often recommended.
Symptoms
- Heartburn or acid taste.
- Cough after meals.
- Hoarseness or sore throat.
- Regurgitation of stomach contents.

When to See a Doctor?
Seek medical care if brown mucus persists, worsens, or is accompanied by other concerning signs. Early evaluation helps prevent complications and identify infections or chronic conditions.
- Persistent brown mucus and cough.
- Blood in mucus from the throat or hemoptysis.
- Shortness of breath or chest pain.
- High fever or chills.
- Unexplained weight loss.
Contact the STAT Specialty Hospital for urgent evaluation if these symptoms occur.
How to Get Rid of Mucus?
Relieving brown mucus involves addressing the underlying cause, keeping airways clear, and supporting lung function. Staying hydrated, using steam therapy, and following medical guidance can help thin thick mucus and reduce discomfort.
Treatments
- Hydration and Steam Therapy: Drinking fluids and inhaling steam help thin mucus, making it easier to cough up and clear from the respiratory tract.
- Expectorants (e.g., Guaifenesin): These medications loosen mucus, reducing congestion and facilitating easier expulsion of brown phlegm.
- Antibiotics (if bacterial infection diagnosed): Targeted antibiotics treat bacterial infections that may be causing brown phlegm with blood, preventing complications.
- Inhaled Bronchodilators: Bronchodilators help open airways, improving airflow and mucus clearance in chronic lung diseases like COPD.
- Chest Physiotherapy: Techniques like postural drainage or percussion loosen thick mucus, especially in conditions like bronchiectasis or cystic fibrosis.
- Smoking Cessation Programs: Quitting smoking reduces tar and chemical buildup in the lungs, preventing chronic airway irritation and brown mucus.
- Nasal Saline Rinse: Rinsing nasal passages flushes out irritants, helping reduce brown mucus from the nose and post-nasal drip.
- Acid Reflux Management: Medications like proton pump inhibitors and lifestyle adjustments reduce throat irritation, contributing to brown mucus in the throat.
- Hospital Interventions (if severe): Procedures such as bronchoscopy or abscess drainage may be necessary in severe or complicated cases to remove infection or blockage.
