Cough with Phlegm: Causes, Treatment and Home Remedies

Coughing up phlegm, or productive cough, involves expelling mucus from the respiratory tract. It is a common symptom of respiratory infections, and depending on the underlying condition, phlegm can vary in colour and consistency. Productive cough can disrupt your daily routine, interfere with sleep, and even cause embarrassment in social situations. However, understanding the causes, symptoms, and treatment options for a cough with phlegm can help you find relief and breathe easier.

What is Coughing up Phlegm?

Coughing up phlegm, also known as productive cough or wet cough, is a common symptom of various respiratory conditions. Phlegm, or mucus, is a sticky substance the respiratory system produces to trap and expel irritants, such as dust, bacteria, or viruses. When the body produces excessive phlegm, it can accumulate in the lungs and airways, resulting in a persistent cough.

Causes of Coughing up Phlegm

Several conditions can contribute to the production of excess phlegm and a cough with phlegm, including:

• Respiratory Infections:
  • Viral infections (e.g., common cold, influenza) can increase the mucus production
  • Bacterial infections (e.g., bronchitis, tuberculosis, or pneumonia) can lead to thickening of the mucus
• Chronic Respiratory Conditions:
  • Asthma can lead to airway inflammation and increased mucus production
  • Chronic obstructive pulmonary disease (COPD) results in persistent cough and mucus
  • Cystic fibrosis causes the development of thick, sticky mucus in the lungs
• Environmental Factors:
  • Air pollution can lead to phlegm
  • Smoke can irritate the mucosa of the respiratory tract and increase mucus production
  • Allergens (e.g., dust, pollen) can increase mucus production
• Postnasal Drip:
  • Sinus infections can cause postnasal drip and phlegm
  • Allergies can cause mucus production and cough

Symptoms of Coughing Up Phlegm

In addition to the persistent cough and production of phlegm, individuals may experience the following symptoms:

• Chest tightness or discomfort
• Wheezing or whistling sound when breathing
• Shortness of breath
• Fatigue
• Sore throat
• Fever (in case of infections)

The colour and consistency of the phlegm can also vary and depend on the underlying cause, such as:

• Yellow or green phlegm may indicate a bacterial infections
• Coughing up white phlegm with bubbles or without bubbles is more familiar with viral infections or allergies
• Brown or rusty phlegm may indicate blood in mucus
• Black phlegm means fungal infection, pneumoconiosis, or inhalation of high amount of smoke

Diagnosis

If you are experiencing a persistent cough with phlegm, it is essential to consult a doctor for an accurate diagnosis. Your doctor may perform the following tests:

• Physical Assessment: Your doctor will listen to your breathing and examine your throat and chest for abnormalities.
• Chest X-ray: This imaging test can help detect any underlying lung conditions or infections.
• Pulmonary Function Tests (PFTs): These tests help measure how well your lungs are working and can diagnose conditions like asthma or COPD.
• Sputum Analysis: Your doctor may analyse a sample of your phlegm to check for the presence of bacteria or other microorganisms.

Treatment

The treatment for a cough with phlegm depends on the underlying reason and the severity of the symptoms. Here are some common treatment options:

• Over-the-counter Medications:
  • Cough suppressants can help suppress the cough reflex.
  • Expectorants can help thin out mucus, making it easier to cough up.
  • Decongestants can help reduce congestion and postnasal drip.
• Prescription Medications:
  • Doctors may recommend antibiotics if a bacterial infection is the cause of the cough with phlegm.
  • Inhaled corticosteroids or bronchodilators for individuals with asthma or COPD.
• Lifestyle Changes:
  • Quitting smoking and avoiding secondhand smoke exposure can significantly improve respiratory health.
  • Reducing exposure to environmental irritants, such as air pollution or allergens, can help prevent exacerbations.

When to Call the Doctor?

While a cough with phlegm is often a self-limiting condition, seek medical attention if:

• Persistent cough lasting more than three weeks
• Coughing up blood or phlegm with an unusual colour or odour
• Severe shortness of breath or wheezing
• High fever or chills
• Chest pain or tightness

Home remedy for cough with phlegm

Several home remedies can help alleviate a cough with phlegm and provide relief. Here are some effective options:

• Honey: Honey is renowned for its natural antibacterial and anti-inflammatory traits that can soothe a sore throat and loosen mucus. Try mixing a tablespoon of honey with warm water or herbal tea.
• Ginger: Ginger is known for its anti-inflammatory and expectorant properties, which can help break down mucus and ease coughing. Add some grated ginger to hot water or tea or make a ginger-honey syrup.
• Saltwater Gargle: Gargling with lukewarm salt water can help decrease inflammation and loosen mucus in the throat. Dissolve half a teaspoon of your edible salt in a glass of lukewarm water and gargle for a few minutes.
• Steamy Showers or Humidifiers: Breathing in warm, moist air can help loosen and thin out mucus, making coughing easier. Take steamy showers or use a humidifier in your living space.
• Herbal Teas: Certain herbal teas, such as liquorice root, marshmallow root, or slippery elm, can have a soothing effect on the throat and help loosen mucus.
• Stay Hydrated: Drinking fluids, such as water, broths, or herbal teas, in optimal amounts can help thin out mucus and keep the respiratory system hydrated.

Conclusion
