What Is Bronchitis?
Bronchitis is inflammation of the bronchial tubes, the airways that carry air to and from the lungs. When these airways become inflamed, they produce excess mucus, making it harder to breathe and often causing a persistent cough. Bronchitis may be acute, lasting a few weeks, or chronic, a long-term condition that is often associated with chronic obstructive pulmonary disease (COPD).
Most cases of acute bronchitis are caused by viral infections and improve with supportive care.
Why Bronchitis Matters
Bronchitis can interfere with breathing, reduce daily activity, and increase the risk of complications in older adults and individuals with chronic lung or heart disease.
Common Causes
- Viral infections
- Bacterial infections (less common)
- Smoking
- Exposure to air pollution
- Chemical fumes or dust
- Chronic lung diseases
Common Symptoms
- Persistent cough
- Coughing up mucus
- Wheezing
- Shortness of breath
- Chest discomfort
- Fatigue
- Low-grade fever in some cases
How Is Bronchitis Diagnosed?
Healthcare providers diagnose bronchitis through a medical history, physical examination, and, when needed, chest X-rays, pulmonary function tests, or laboratory testing to rule out other conditions.
How Is Bronchitis Treated?
Treatment depends on the cause and may include rest, hydration, medications to relieve symptoms, inhalers for some individuals, and antibiotics only when a bacterial infection is confirmed or strongly suspected.
How Home Care Can Help
Home care professionals encourage hydration, reinforce medication schedules, monitor breathing and oxygen levels when appropriate, support breathing exercises, and observe for signs of worsening respiratory symptoms.
Home Care Tip
Drink plenty of fluids, unless your healthcare provider has advised otherwise, to help thin mucus and make coughing more effective.
Frequently Asked Questions About Bronchitis
Is bronchitis contagious?
Acute viral bronchitis can be contagious because the viruses that cause it spread from person to person. Chronic bronchitis itself is not contagious.
Do antibiotics treat bronchitis?
Most cases of acute bronchitis are caused by viruses, so antibiotics are usually not needed. Your healthcare provider will determine whether antibiotics are appropriate.
Can home care professionals help someone with bronchitis?
Yes. Home care professionals support medication adherence, encourage hydration, monitor respiratory symptoms, and help individuals recover safely at home.
When to Seek Immediate Medical Care
Seek immediate medical attention if you experience severe shortness of breath, chest pain, blue lips or fingertips, coughing up large amounts of blood, or rapidly worsening breathing problems.
