COPD

Overview

Chronic Obstructive Pulmonary Disease (COPD) is a long-term lung condition in which the airways are persistently narrowed and the air sacs are damaged, causing ongoing breathlessness, a chronic productive cough and reduced exercise tolerance. It is most often caused by long-term cigarette smoking or biomass-fuel (chulha) smoke exposure. COPD is not fully reversible, but with the right treatment, smoking cessation, vaccinations and pulmonary rehabilitation, symptoms can be improved, flare-ups reduced, and progression slowed.

Symptoms

• Chronic breathlessness, initially on exertion and later at rest.
• A chronic cough, often productive of phlegm, especially in the mornings.
• Wheeze and chest tightness.
• Reduced exercise tolerance and tiredness.
• Flare-ups (exacerbations) with increased breathlessness, cough and phlegm, often triggered by infection.

Causes and risk factors

• Cigarette smoking — the leading cause.
• Long-term biomass-fuel smoke exposure from cooking or heating.
• Occupational dust and fume exposure.
• Genetic factors (alpha-1 antitrypsin deficiency, rare).

Diagnosis

Diagnosis is made from the history and confirmed with spirometry, which shows persistently reduced airflow that does not fully reverse. A chest X-ray, pulse oximetry and, in some cases, a CT scan help assess the lungs and exclude other causes. COPD includes chronic bronchitis and emphysema — see Chronic Bronchitis for the bronchitis-focused perspective.

Treatment and management

Treatment combines bronchodilator inhalers (long-acting relievers), inhaled steroids for frequent flare-ups, smoking cessation, annual flu and pneumococcal vaccinations, pulmonary rehabilitation, and oxygen for severe cases. Flare-ups are treated promptly with increased inhalers and, where a bacterial infection is present, antibiotics and steroids. Weight management and nutrition matter, as both overweight and underweight states affect breathlessness.

Warning signs — seek urgent care

• A severe flare-up with marked breathlessness, confusion or bluish lips.
• Very low oxygen on a pulse oximeter.
• Chest pain or fainting with breathlessness.
• Inability to manage at home despite increased inhaler use.

How we help

Dr. Nayak confirms COPD with lung function testing, optimises inhaler treatment, supports smoking cessation, and monitors for flare-ups and complications. Consultations are available in-clinic in Bhubaneswar and over teleconsultation.
