Chronic obstructive lung disease

From WikiMD's Wellness Encyclopedia

Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term breathing problems and poor airflow. The main symptoms include shortness of breath and cough with sputum production. COPD is a progressive disease, meaning it typically worsens over time.

Causes[edit | edit source]

The primary causes of COPD are tobacco smoking and exposure to air pollution, including indoor air pollution such as biomass fuel used for cooking and heating. Genetics also play a role in the development of COPD, even if the person has never smoked or been exposed to strong lung irritants in the workplace.

Pathophysiology[edit | edit source]

COPD is a disease that involves chronic inflammation of the bronchial tubes, which results in swelling and narrowing of the airways. This inflammation leads to the production of large amounts of mucus, which further obstructs the airways and causes symptoms such as cough and shortness of breath.

Diagnosis[edit | edit source]

Diagnosis of COPD is based on symptoms, a physical examination, and diagnostic tests. A spirometry test is essential for the diagnosis of COPD and shows how well the lungs are working. Other tests may include a chest X-ray or a CT scan of the chest.

Treatment[edit | edit source]

While there is no cure for COPD, treatments can help manage symptoms and slow the progression of the disease. Treatments include smoking cessation, medications, pulmonary rehabilitation, and oxygen therapy. In severe cases, lung transplantation may be considered.

Prognosis[edit | edit source]

The prognosis for COPD varies depending on the stage of the disease and the overall health of the individual. With proper management, most people with COPD can achieve good symptom control and quality of life, as well as reduced risk of other associated conditions such as heart disease and lung cancer.

Epidemiology[edit | edit source]

COPD affects millions of people worldwide and is often underdiagnosed. It is most common in people over the age of 40 who have a history of smoking. COPD is the third leading cause of death worldwide.
