Chronic Bronchitis

Overview

Chronic bronchitis is defined clinically as a productive cough on most days for at least three months in two consecutive years. It is part of the COPD spectrum, caused by long-term irritation of the airways — most often from cigarette smoking or biomass-fuel smoke. The persistent inflammation produces excess mucus, causing the daily cough and phlegm. This page focuses on the bronchitis-within-COPD perspective; the broader airflow limitation is covered on the COPD page, and acute short-term bronchitis on the Acute Bronchitis page.

Symptoms

• A daily cough, often worse in the mornings, productive of phlegm.
• Breathlessness on exertion that progresses over time.
• Wheeze and chest tightness.
• Frequent flare-ups with increased cough, phlegm and breathlessness.

Causes

Long-term cigarette smoking is the leading cause. Biomass-fuel smoke from cooking, occupational dust and fumes, and recurrent airway infections also contribute. The ongoing irritation drives mucus over-production and airway narrowing.

Diagnosis

Diagnosis is based on the history of a chronic productive cough and confirmed with spirometry showing airflow limitation (placing it within COPD). A chest X-ray helps exclude other causes, and sputum tests or a chest X-ray are ordered during flare-ups when infection is suspected.

Management

Management centres on smoking cessation, bronchodilator inhalers, inhaled steroids for frequent flare-ups, vaccinations (flu and pneumococcal), pulmonary rehabilitation, and prompt treatment of flare-ups with increased inhalers and, where bacterial infection is present, antibiotics. Hydration helps clear mucus.

Warning signs — seek urgent care

• A severe flare-up with marked breathlessness, confusion or bluish lips.
• Blood in the phlegm.
• Very low oxygen on a pulse oximeter.
• Fever and worsening breathlessness.

How we help

Dr. Nayak confirms chronic bronchitis within the COPD spectrum, optimises inhaler treatment, supports smoking cessation, and manages flare-ups promptly. Consultations are available in-clinic in Bhubaneswar and over teleconsultation.
