What are Chronic Lower Respiratory Diseases?
Chronic Lower Respiratory Diseases (CLRD) is a group of lung diseases that cause breathing difficulties and airflow obstruction.
Some of the most common CLRDs include:
» Asthma: A chronic disease that affects the airways in the lungs, causing recurrent attacks of breathlessness and wheezing due to airway narrowing. It is the most common chronic disease among children.
» Chronic Obstructive Pulmonary Disease (COPD): A condition that includes chronic bronchitis and emphysema. It affects the airways and causes long-term breathing problems, often due to smoking or exposure to certain chemicals or fumes.
» Cystic Fibrosis: A genetic disease that causes thick, sticky mucus to build up in the lungs, digestive tract, and other areas of the body. This can lead to severe respiratory problems.
» Lung Cancer: A type of cancer that starts in the lungs and can cause a range of respiratory symptoms, such as coughing, wheezing, and shortness of breath.
» Tuberculosis (TB): A bacterial infection that primarily affects the lungs, causing symptoms such as coughing, chest pain, and difficulty breathing.
» Occupational Lung Diseases: These are respiratory diseases caused by exposure to certain substances in the workplace, such as dust, chemicals, or fumes. Examples include pneumoconiosis and occupational asthma.
» Pulmonary Hypertension: A type of high blood pressure that affects the arteries in the lungs and the right side of the heart. It can cause shortness of breath, dizziness, and chest pain.
Tobacco smoke, air pollution, allergens, and frequent lower respiratory infections during childhood are some of the risk factors for CLRDs. While these diseases aren’t curable, various forms of treatment can help control symptoms and improve daily life for people living with these conditions.
Trend
• In the US, approximately 16 million people have been diagnosed with COPD, and it is estimated that an additional 16 million have undiagnosed COPD.
• The number of people with CLRD has been increasing over the years. In 2022, the percentage of adults who have ever been diagnosed with COPD, emphysema, or chronic bronchitis was 4.6%.
History of Chronic Lower Respiratory Diseases
The history of CLRD dates back to ancient times, with evidence of its existence found in Egyptian mummies. However, it was not until the 19th century that the term "chronic bronchitis" was first used to describe the condition. In the 20th century, the link between smoking and CLRD was established, leading to a better understanding of the disease and its prevention. Today, CLRD is a major public health issue worldwide.
