Most septal deformities result in no symptoms, and you may not even know you have a deviated septum. Some septal deformities, however, may cause the following signs and symptoms: Obstruction of one or both nostrils. This obstruction can make it difficult to breathe through the nostril or nostrils.
COPD is a type of obstructive lung disease in which chronic incompletely reversible poor airflow (airflow limitation) and inability to breathe out fully (air trapping) exist. The poor airflow is the result of breakdown of lung tissue (known as emphysema) and small airways disease (known as obstructive bronchiolitis).
Lung disease is any problem in the lungs that prevents the lungs from working properly. There are three main types of lung disease: Airway diseases -- These diseases affect the tubes (airways) that carry oxygen and other gases into and out of the lungs. They usually cause a narrowing or blockage of the airways. Airway diseases include asthma, emphysema, bronchiectasis, and chronic bronchitis.
