Lungs play an essential role in keeping us alive by enabling oxygen to flow through our body and removing carbon dioxide. However, they are susceptible to numerous diseases that can affect their ability to function efficiently. According to the World Health Organization (WHO), respiratory diseases are among the leading causes of illness and death worldwide. Knowing the common lung diseases can help us recognize early symptoms, seek treatment, and take preventive measures.
In this blog, we’ll explore seven of the most common lung diseases, their causes, symptoms, and ways to manage or prevent them.
