Lung problems refer to various conditions that affect the lungs' ability to function properly. Common issues include asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. These conditions can lead to symptoms such as coughing, wheezing, shortness of breath, and chest tightness. Many factors can contribute to lung problems, including smoking, exposure to pollutants, and respiratory infections. Early diagnosis and treatment are essential for managing these conditions and improving quality of life. Maintaining lung health can involve avoiding irritants, exercising regularly, and following medical advice.
