People with sleep apnea often wake up suddenly due to shortness of breath. Upon waking, they may also choke, snort, or gasp. You may not even be aware of some of these symptoms while you sleep, but waking up feeling out of breath is a strong indicator that you have sleep apnea.
Shortness of breath is a common symptom of chronic obstructive pulmonary disease (COPD). Both chronic bronchitis and emphysema can cause shortness of breath. The symptom is also called âbreathlessnessâ or âdyspnea.â. People with COPD have damage to their lungs that makes it harder to breathe. 1  They often feel short of breath because it takes more effort to make air travel in and out of the lungs. This feeling of breathlessness is also described as: 2  More effort needed to breathe. 3  Feeling of heaviness in the chest. 4  Hunger for air. 5  Gasping for air.
