What is Shortness of Breath?

Shortness of breath is a symptom, indicating difficulty in breathing or a feeling of breathlessness. It can be a manifestation of various underlying conditions such as asthma, heart disease, or lung disorders.

The majority of cases of shortness of breath are caused by heart or respiratory issues. The heart and lungs are essential in carrying oxygen to the tissues and removing carbon dioxide.
