**What is Chronic Bronchitis?**
**Definition:**
Chronic bronchitis, also known as **chronic obstructive bronchitis (COB)**, is a long-term inflammatory condition that affects the bronchi, the large airways that carry air in and out of our lungs. It causes a persistent cough with wheezing or shortness of breath.
**Symptoms:**
* Persistent cough that lasts for at least three months of the year, for two or more consecutive years
* Coughing up clear, colorless, or whitish mucus
* Wheezing or shortness of breath, especially during exertion
**Causes:**
* **Smoking** (primary cause)
* Air pollution
* Occupational exposure to dust, fumes, or gases
* Previous respiratory infections
**Pathophysiology:**
* Repeated inflammation in the airways leads to **chronic swelling and irritation.**
* The bronchi become thicker and produce more mucus, which narrows the airways and makes it harder to breathe.
* Airflow becomes obstructed, leading to symptoms such as coughing and shortness of breath.
**Complications:**
* **Exacerbations:** Sudden worsening of symptoms that require medical attention
* **Lung infections:** Pneumonia, bronchitis, and influenza
* **Respiratory failure:** In severe cases, the body may not be able to get enough oxygen
* **Cardiovascular disease:** Increased risk due to inflammation and narrowed airways
**Diagnosis:**
* Physical examination and medical history
* Pulmonary function tests (spirometry) to measure airflow
* Chest X-ray or CT scan to rule out other lung conditions
**Treatment:**
* **Medication:**
* Bronchodilators to open airways
* Inhaled steroids to reduce inflammation
* **Oxygen therapy:** For severe cases
* **Pulmonary rehabilitation:** To improve breathing and quality of life
* **Lifestyle modifications:**
* Quitting smoking
* Avoiding air pollutants
* Getting regular exercise
**Prevention:**
* **Avoid smoking:** Smoking is the leading cause of chronic bronchitis.
* **Reduce exposure to air pollution:** Wear masks when necessary, stay indoors during peak pollution times.
* **Get vaccinated:** Vaccinations against respiratory infections can reduce the risk of exacerbations.
**Outlook:**
Chronic bronchitis is a long-term condition that cannot be cured, but it can be managed with proper treatment and lifestyle changes. Early diagnosis and treatment are crucial to prevent complications and improve quality of life.
This is the definition, causes and symptoms of chronic bronchitis.
