how do i know if i have copd

To know if you have COPD (Chronic Obstructive Pulmonary Disease), watch for symptoms such as a long-term or chronic cough that produces a lot of mucus, shortness of breath especially during physical activity, wheezing, chest tightness, and fatigue. These symptoms often develop gradually and may worsen over time. If you have these symptoms, particularly if you are over 35 and have a history of smoking or exposure to lung irritants (like secondhand smoke, pollution, or workplace fumes), it is important to see a doctor for evaluation. Doctors typically use a lung function test called spirometry—which measures how much air you can blow out and how fast—to diagnose COPD. They may also perform a chest X-ray or other imaging tests to help confirm the diagnosis and rule out other conditions. If symptoms like persistent cough with mucus, increased breathlessness, or chest tightness are present, it is recommended to make an appointment with a healthcare provider. Early diagnosis and treatment are important to slow the disease progression and improve quality of life.
