Respiratory conditions refer to a range of diseases that affect the lungs and airways, making it difficult to breathe. Common examples include asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. These conditions can cause symptoms such as coughing, wheezing, shortness of breath, and chest tightness. Many respiratory conditions are caused by factors like smoking, air pollution, and allergens. Treatment options vary depending on the specific condition and may include medications, lifestyle changes, and in some cases, oxygen therapy. Early diagnosis and management are essential for improving quality of life and preventing complications.
