The respiratory system is an essential part of the human body, allowing us to breathe in oxygen and expel carbon dioxide. Respiratory disorders can have a significant impact on a person's quality of life. The top 10 disorders of the respiratory system are asthma, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonia, tuberculosis, cystic fibrosis, pulmonary embolism, acute respiratory distress syndrome (ARDS), laryngitis, and sleep apnea. Asthma is a chronic inflammatory condition of the airways, which can lead to shortness of breath, wheezing and coughing. COPD is a progressive disease characterized by difficulty breathing, fatigue, and chest tightness. Bronchitis is an inflammation of the bronchial tubes, which can cause coughing and chest discomfort. Pneumonia is an infection of the lungs that results in coughing, fever, and difficulty breathing. Tuberculosis is a highly contagious bacterial infection that can cause serious respiratory problems. Cystic fibrosis is a genetic disorder in which the lungs and digestive system become clogged with thick mucus. Pulmonary embolism is a blockage of the pulmonary artery, which can cause chest pain and trouble breathing. ARDS is an acute lung condition that can cause fluid to build up in the lungs and lead to breathing difficulties. Laryngitis is an inflammation of the larynx, which can cause hoarseness, coughing, and difficulty speaking. Lastly, sleep apnea is a disorder that causes the patient to stop and start breathing during sleep, resulting in frequent nighttime awakenings.
