Description

Acute bronchitis is a common respiratory condition which refers to the inflammation of the bronchial tubes, which are responsible for carrying air to and from the lungs. The inflammation leads to increased production of mucus, which can cause a persistent cough and other respiratory symptoms. Unlike chronic bronchitis, which is a long-term condition often linked to smoking, acute bronchitis is usually caused by a viral infection and tends to resolve on its own within a few weeks [1].

Symptoms

The symptoms of acute bronchitis can vary in severity but commonly include;

Cough: Initially dry and irritating, which may later produce phlegm.

Mucus production: Often clear, yellow or green in color.

Fatigue: Feeling tired or exhausted due to the body's response to infection.

Chest discomfort: Mild to moderate chest discomfort or soreness.

Shortness of breath: Difficulty in breathing, especially during physical activity.

Slight fever and chills: Some patients may experience a low-grade fever and chills.

These symptoms can overlap with those of other respiratory conditions, making an accurate diagnosis important for effective treatment [2].

Causes

Acute bronchitis is commonly caused by viral infections, particularly influenza viruses, rhinoviruses (common cold viruses), Respiratory Syncytial Virus (RSV). These viruses spread through respiratory droplets when an infected person coughs or sneezes. Bacterial infections can also lead to acute bronchitis, but they are less common [3-5]. Other risk factors include;

Smoking: Both active and passive smoking can increase the risk and severity of bronchitis.

Environmental irritants: Exposure to dust, fumes or air pollution can irritate the bronchial tubes.

Weakened immune system: People with compromised immune systems, such as those with Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS) or undergoing chemotherapy, are more susceptible.

Gastric reflux: This condition, where stomach acid rises into the esophagus and throat, can also contribute to bronchial irritation.

Diagnosis

Diagnosing acute bronchitis typically involves;

Medical history: Including symptoms and recent illnesses.

Physical examination: Listening to the lungs for abnormal sounds such as wheezing.

Tests: In some cases, a chest X-ray or sputum culture may be ordered to rule out other conditions like pneumonia.

In many cases, doctors can diagnose acute bronchitis based on symptoms and a physical examination alone, without the need for additional tests [6,7].

Treatment

Treatment for acute bronchitis focuses on relieving symptoms and supporting the body's natural healing process. Common approaches include;

Rest: Getting adequate rest allows the body to recover more quickly.

Hydration: Drinking plenty of fluids helps thin mucus and ease coughing.

Over-the-counter medications: Such as ibuprofen or acetaminophen for pain and fever and cough suppressants or expectorants to manage cough symptoms.

Inhalation therapy: Using a humidifier or steam inhalation can help soothe irritated airways.

Avoiding irritants: Such as cigarette smoke or other pollutants that can worsen symptoms.

Antibiotics are not typically prescribed for acute bronchitis unless there is a bacterial infection present or if symptoms persist or worsen over time. Overuse of antibiotics contributes to antibiotic resistance and should be avoided unless absolutely necessary [8].

Complications

While acute bronchitis usually resolves without complications, in some cases, it can lead to;

Pneumonia: Particularly in elderly adults or those with weakened immune systems.

Chronic bronchitis: Recurrent episodes of bronchitis can contribute to chronic inflammation and airway damage.

Worsening of underlying conditions: Such as asthma or Chronic Obstructive Pulmonary Disease (COPD).

Seeking medical attention promptly if symptoms worsen or persist beyond a few weeks can help prevent complications and ensure appropriate treatment [9].

Prevention

Preventing acute bronchitis involves reducing exposure to viruses and other respiratory irritants. Strategies include;

Hand hygiene: Regular handwashing with soap and water, especially during cold and flu season.

Avoiding close contact: With individuals who have respiratory infections.

Quitting smoking: Both active and passive smoking increase the risk of bronchitis [10].

Vaccinations: Annual flu vaccines can reduce the risk of influenza-related bronchitis.

Healthy lifestyle: Eating a balanced diet, exercising regularly and getting adequate sleep support overall immune function.

Conclusion

Acute bronchitis is a common respiratory condition that typically follows a viral infection and resolves within a few weeks with supportive care. Recognizing the symptoms and understanding the causes can help individuals seek timely treatment and adopt preventive measures to reduce their risk. While most cases of acute bronchitis do not require antibiotics, should consult healthcare professional if the symptoms persist which is necessary to prevent complications and ensure appropriate management. By practicing good hygiene, avoiding respiratory irritants and maintaining a healthy lifestyle, individuals can reduce their chances of developing acute bronchitis and other respiratory infections.
