Oxygen is essential. Our bodies are unable to properly function without a sufficient supply of oxygen. Our quality of life is thus greatly affected when the supply of oxygen is hindered because of a respiratory illness. Respiratory diseases are among the most prevalent diseases. Various diseases can affect the respiratory system. In addition to acute infections such as colds, whooping cough, and bronchitis, these also include chronic forms such as asthma and COPD (chronic obstructive pulmonary disease). While acute respiratory diseases can usually be cured in a relatively short time, chronic diseases usually require life-long treatment. On this page, you will learn more about how asthma and COPD can be treated and how you can best cope with these diseases.
