Lung disorders refer to a variety of conditions that affect the lungs and their ability to function properly. Common examples include asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. These disorders can lead to symptoms such as coughing, wheezing, shortness of breath, and chest tightness, impacting a person's overall health and quality of life. Many lung disorders are caused by factors like smoking, air pollution, and infections. Diagnosis often involves medical history, physical exams, and tests such as chest X-rays or pulmonary function tests. Treatment options may include medications, lifestyle changes, and in some cases, surgery to improve lung function and alleviate symptoms.
