The Significant Duties of a Pulmonologist in Chronic Lung Disease Management

When it comes to our health, there are many different types of specialists that we may need to see for various conditions. One such specialist is a pulmonologist, who focuses on the respiratory system and related diseases. But what does a pulmonologist do exactly? In this article, we will explore the scope of what does a pulmonologist do, from diagnosing and treating asthma to managing lung cancer.

Firstly, pulmonologists are often involved in the diagnosis and management of asthma. Asthma is a chronic respiratory disease that causes the airways to become inflamed, tight, and produce extra mucus. This can lead to symptoms such as wheezing, coughing, and shortness of breath. Pulmonologists can help to determine the severity of asthma, prescribe medications, and provide education on avoiding triggers that can worsen asthma symptoms.

Secondly, pulmonologists also treat chronic obstructive pulmonary disease (COPD). This is a progressive lung disease that includes emphysema and chronic bronchitis. Symptoms of COPD include difficulty breathing, coughing, and excess mucus production. A pulmonologist may help to manage COPD through medications, oxygen therapy, and pulmonary rehabilitation programs that include breathing exercises and physical activity.

Thirdly, pulmonologists are often involved in the diagnosis and treatment of lung cancer. Lung cancer is the leading cause of cancer-related deaths worldwide, and early diagnosis and treatment are crucial for improving outcomes. Pulmonologists can perform diagnostic tests such as CT scans, biopsies, and bronchoscopies to determine the stage and extent of lung cancer. They may also work closely with oncologists to develop a treatment plan, which can include surgery, chemotherapy, radiation therapy, and palliative care.

Fourthly, pulmonologists can help to manage sleep disorders such as sleep apnea. Sleep apnea is a common condition where breathing temporarily stops or becomes shallow during sleep, which can lead to disrupted sleep and daytime fatigue. Pulmonologists may perform sleep studies to diagnose sleep apnea and recommend treatments such as continuous positive airway pressure (CPAP) machines, oral appliances, and lifestyle modifications.

Lastly, pulmonologists can also provide care for pulmonary hypertension. This is a type of high blood pressure that affects the arteries in the lungs, making it harder for blood to flow through them. Symptoms of pulmonary hypertension include shortness of breath, fatigue, chest pain, and fainting. Pulmonologists may perform diagnostic tests such as echocardiograms and right-heart catheterizations to determine the severity of pulmonary hypertension. Treatment options include medications that widen blood vessels and improve blood flow, as well as supplemental oxygen therapy.


In conclusion, pulmonologists play a crucial role in diagnosing and treating a wide range of respiratory conditions, from asthma and COPD to lung cancer and sleep disorders. If you are experiencing symptoms such as difficulty breathing, coughing, wheezing, or fatigue, it may be beneficial to seek the expertise of a pulmonologist. With their knowledge and experience, they can help to improve your respiratory health and overall quality of life.
