Bronchitis

Etiologic and Other Factors Leading to Bronchitis:

1. Etiologic Factors:
   • Infections: Viral infections (e.g., influenza, rhinovirus, or RSV) are the most common causes. Bacterial infections (e.g., Mycoplasma pneumoniae, Bordetella pertussis) are less common.
   • Chronic Irritants: Smoking, air pollution, chemical fumes, or dust exposure can lead to chronic bronchitis.
   • Allergic Reactions: Environmental allergens may trigger bronchitis in susceptible individuals.
2. Other Contributing Factors:
   • Weakened Immune System: Conditions like diabetes or prolonged stress can increase susceptibility.
   • Pre-existing Lung Conditions: Asthma, COPD, or previous lung infections can predispose one to bronchitis.
   • Weather Changes: Cold, damp environments may exacerbate symptoms.

When to Seek Professional Help:

• High fever (over 102°F or 39°C) lasting more than 3 days.
• Persistent or worsening symptoms after 10 days.
• Shortness of breath, wheezing, or chest pain.
• Cough producing blood or thick yellow/green mucus.
• Pre-existing respiratory conditions like asthma or COPD worsening.
• Signs of dehydration (e.g., dry mouth, dizziness, reduced urination).

Christopher Hobbs:

“Bronchitis is inflammation of the bronchi, part of the system of tubes that transport air throughout the lungs. Bronchitis can be acute, which is often associated with viral or bacterial infections, or chronic, which can be caused by long-term exposure to air pollutants and cigarette smoke. Chronic bronchitis can also occur with chronic asthma, and it is often difficult to separate the two.”
