Bronchitis: Causes, Symptoms, Diagnosis & Treatment

Bronchitis is the inflammation of the bronchial tubes that carry air to your lungs. It can be acute or chronic, with symptoms like persistent cough, mucus production, and chest discomfort. Causes range from infections to environmental irritants. Bronchitis diagnosis involves medical history, physical exams, and tests like chest X-rays. Treatment may include rest, hydration, bronchitis medication, and in some cases, inhalers. Seek medical attention if symptoms worsen or persist.

What is Bronchitis?

Bronchitis occurs when the lining of the bronchial tubes becomes inflamed, causing difficulty in breathing and mucus buildup. This condition can range from short-term (acute) to long-lasting (chronic), often affecting people exposed to respiratory infections or pollutants.

Types of Bronchitis

Acute Bronchitis

Also called a chest cold, acute bronchitis typically results from viral infections like the flu or a cold. It lasts for a few days to weeks and is common during winter. 

• Key Features: Short-term inflammation, often resolving without complications. 

• Triggers: Viral infections, exposure to smoke, or allergens. 

Chronic Bronchitis

This is a long-term form of bronchitis and is a part of chronic obstructive pulmonary disease (COPD). It is marked by recurrent coughing and mucus production for at least three months annually over two years. 

• Key Features: Persistent inflammation that damages lung tissue over time. 

Triggers: Long-term smoking, air pollution, or occupational hazards.

Bronchitis Symptoms

Recognising bronchitis symptoms early can help manage the condition effectively: 

• Persistent cough (dry or producing mucus): A nagging cough that may be dry or bring up yellow or clear mucus. 

• Wheezing or whistling sounds during breathing: You might hear a high-pitched, whistling sound when you breathe, especially during exhalation. 

• Shortness of breath or tightness in the chest: Breathing may feel heavy or restricted due to inflammation and mucus buildup in the airways. 

• Fatigue or low energy: The ongoing cough and effort to breathe can leave you feeling unusually drained and tired. 

• Mild fever or chills: A slight fever or chills may accompany bronchitis, particularly if it’s caused by an infection. 

In chronic bronchitis, symptoms tend to worsen over time, while in acute bronchitis, they may subside within a few weeks.

What Causes Bronchitis?

Understanding bronchitis causes can help prevent the condition: 

1. Viral Infections: This is the most common cause of acute bronchitis. It is most commonly caused by the same viruses responsible for colds and the flu. 
2. Smoking: Tobacco smoke is the leading trigger for chronic bronchitis, irritating and damaging bronchial tubes over time. 
3. Pollutants: Exposure to air pollution, dust, and industrial fumes increases the risk. 
4. Allergies and Irritants: Seasonal allergens, strong odours, or chemical exposure can also lead to bronchial inflammation. 

How is Bronchitis Diagnosed?

Bronchitis diagnosis starts with a thorough examination by a healthcare provider: 

1. Medical History: The doctor will ask about your symptoms, smoking habits, or recent illnesses. 
2. Physical Exam: Listening to your lungs with a stethoscope can reveal wheezing or abnormal sounds. 
3. Chest X-ray: Used to rule out pneumonia or other conditions. 
4. Sputum Test: Analyzing mucus can help identify the presence of infections. 

Pulmonary Function Tests: These measure lung capacity and airflow, often used for the diagnosis of chronic bronchitis.

Treatment and Management

Bronchitis treatment depends on the type and severity of the condition: 

Home Remedies for Acute Bronchitis

• Hydration: Drinking plenty of fluids helps loosen mucus, making it easier to clear from your chest. 

• Rest: Adequate rest allows your body to recover. 

• Steam Inhalation: This can soothe irritated airways and reduce coughing. 

Medications

• Bronchitis Medication: Over-the-counter pain relievers like paracetamol can reduce fever and discomfort. 

• Cough Suppressants: These may be prescribed to ease persistent coughs. 

• Inhalers: For severe cases, bronchodilators can open airways. 

Chronic Bronchitis Management

• Lifestyle Changes: Quitting smoking and avoiding pollutants are essential. 

• Pulmonary Rehabilitation: A program combining exercise and breathing techniques to improve lung function. 

When to See a Doctor? 

Seek immediate medical attention if: 

• Your cough lasts more than three weeks. 

• You experience high fever, chest pain, or wheezing. 

• There is blood in your mucus. 

• Shortness of breath worsens despite treatment.

By maintaining a healthy lifestyle and seeking timely medical care, you can reduce the risk of complications and improve your quality of life.

Frequently Asked Questions

Which is the most common symptom of bronchitis?

A persistent cough, often accompanied by mucus production, is the most common symptom of bronchitis. 

What is the first-line treatment for bronchitis?

For acute bronchitis, rest, hydration, and over-the-counter medications are typically effective. In severe cases, inhalers or prescribed bronchitis medication may be needed to ease breathing. For chronic bronchitis, treatment focuses on bronchodilators, corticosteroids, and pulmonary rehabilitation to manage symptoms. Antibiotics are only prescribed for bacterial infections. Always consult a doctor for the right treatment plan based on your condition. 

What not to eat with bronchitis?

Avoid dairy products as they can thicken mucus, along with fried or overly processed foods that may worsen inflammation.
