COPD – Everything you need to know

Professionally updated: January 12, 2026

COPD, also known as Chronic Obstructive Pulmonary Disease, is a common term for a group of lung diseases that cause breathing difficulties. The disease affects the airways and reduces the amount of air that can move in and out of the lungs. This can lead to a range of symptoms and affect quality of life.

Causes of COPD

COPD can be caused by years of exposure to harmful particles or gases, especially from tobacco smoke. Other risk factors include air pollution, occupational exposure to dust and chemicals, and frequent childhood lung diseases.

Can you recognize these symptoms?

The most common symptoms of COPD are shortness of breath, chronic cough, and increased mucus production. Over time, the symptoms may become more severe, and people with COPD may experience more frequent shortness of breath, chest pain, swollen ankles, weight loss and fatigue.

Diagnosis

To diagnose COPD, a doctor will typically use spirometry, which is a lung function test. This test measures the amount and speed of air a person can inhale and exhale. Other tests may include chest X-rays and arterial blood gas analysis.

COPD treatment

Although COPD cannot be cured, the symptoms can be treated and managed. Treatment options include medication, physiotherapy, pulmonary rehabilitation, and in severe cases, surgery. It is important to avoid tobacco smoke and other lung-damaging substances to prevent the progression of the disease.

Good quality of life

Living with COPD can be challenging, but with the right treatment and support, it is possible to maintain a good quality of life. It is important to follow your doctor's advice, take your medication as prescribed, participate in rehabilitation programs, and avoid triggers that can worsen symptoms.

COPD prevention

The best way to prevent COPD is to avoid smoking or to quit smoking. Other preventive measures include protecting yourself from harmful chemicals, dust, and air pollution in the workplace and in the environment. Annual flu vaccines and pneumococcal vaccines are also recommended for people with COPD to prevent complications.
