Chronic Bronchitis vs. Bronchiectasis: Understanding the Difference

Both are chronic respiratory diseases but differ in airway pathology.

Chronic Bronchitis

• Airways (bronchi) are inflamed and produce excess mucus.
• Causes coughing, wheezing, shortness of breath.
• Often caused by smoking; also air pollution, allergies, infections.

Bronchiectasis

• Airways are permanently damaged and widened.
• Causes coughing, wheezing, shortness of breath, large amounts of mucus.
• Often caused by infections; also genetic disorders, cystic fibrosis, rheumatoid arthritis.

Key Difference

Chronic bronchitis involves inflammation and mucus hypersecretion; bronchiectasis involves structural airway damage and dilation, leading to complications like recurrent infection, atelectasis, and respiratory failure.

Treatment

Both: medications, oxygen therapy, lifestyle changes. Bronchiectasis may require surgery in some cases.
