What is chronic bronchitis, and how does it differ from acute bronchitis?

Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) characterized by:

1. Persistent inflammation: Long-term inflammation of the bronchial tubes (airways).
2. Excess mucus production: Thick, sticky mucus that’s difficult to cough up.
3. Coughing and wheezing: Persistent cough and wheezing for at least 3 months in 2 consecutive years.
4. Airflow limitation: Narrowing of the airways, making breathing difficult.

Chronic bronchitis differs from acute bronchitis in:

Duration: Chronic bronchitis persists for months or years, while acute bronchitis lasts for a few weeks.
Causes: Chronic bronchitis is often caused by long-term exposure to irritants like smoke or pollution, while acute bronchitis is usually caused by a viral or bacterial infection.
Symptoms: Chronic bronchitis symptoms are persistent and progressive, while acute bronchitis symptoms are temporary and resolve with treatment.
Impact on lungs: Chronic bronchitis leads to permanent damage and scarring of the airways, while acute bronchitis does not cause long-term damage.

Key differences:

Chronic bronchitis:

– Long-term inflammation and damage
– Persistent symptoms
– Progressive airflow limitation
– Often caused by smoking or pollution

Acute bronchitis:

– Short-term inflammation and infection
– Temporary symptoms
– No long-term damage
– Usually caused by viral or bacterial infections
