What is Acute Bronchitis?
- An infection of the main airways (bronchi) that leads to inflammation and swelling
- Can be caused by viruses, bacteria, or irritants like smoke
- Often develops after a cold or the flu
- Usually lasts 1-2 weeks, but cough can persist for several weeks
What Causes Acute Bronchitis?
- Viruses – such as influenza, rhinovirus, or respiratory syncytial virus (RSV)
- Bacteria – like Streptococcus pneumoniae or Haemophilus influenzae
- Irritants – like smoke, dust, or chemical fumes
- Weakened immune system
- Recent respiratory illnesses like the common cold
Preventing Acute Bronchitis
- Get the flu vaccine annually
- Avoid exposure to lung irritants like smoke and air pollution
- Wash hands frequently to prevent the spreading of viral infections
- Stay hydrated and get enough rest when sick
- Cover your coughs and sneezes to prevent spreading illness
Signs and Symptoms of Acute Bronchitis
- Persistent cough, often with mucus production
- Chest discomfort or tightness
- Wheezing or whistling sound when breathing
- Low-grade fever
- Sore throat
- Fatigue
Treating Acute Bronchitis
- Rest and drink plenty of fluids
- Over-the-counter pain relievers and cough suppressants
- Prescription medications to help manage symptoms, if needed
- Medical treatment only for confirmed bacterial infections
- Monitoring for worsening symptoms that require medical attention
Self-Care for Acute Bronchitis
- Get plenty of rest
- Stay hydrated by drinking lots of water, broth, or herbal tea
- Use a humidifier to keep air moist
- Suck on cough drops or hard candy to soothe a sore throat
- Avoid irritants like smoke and dust
Medications for Acute Bronchitis
- Cough suppressants like dextromethorphan or guaifenesin
- Expectorants to thin mucus and make coughing more productive
- Decongestants to reduce swelling in the airways
- Bronchodilators to open up the airways and improve breathing
- Prescription medications only if the infection is bacterial
Risk Factors for Acute Bronchitis
- Weakened immune system
- Chronic lung diseases like COPD or asthma
- Smoking or exposure to secondhand smoke
- Air pollution or exposure to lung irritants
- Recent respiratory illness like a cold or flu
How Acute Bronchitis Spreads
- Spread through coughing and sneezing, dispersing virus particles or bacteria
- Touching contaminated surfaces then touching your face, nose, or mouth
- Close contact with someone who has an active respiratory infection
- Sharing food, drinks, or utensils with an infected person
Summary
Acute bronchitis is a common and usually mild condition that often resolves on its own with proper self-care. However, it’s important to monitor for signs of worsening symptoms or progression to pneumonia, which would require prompt medical attention. Let me know if you have any other questions!
