Sometimes it can be hard to know how serious your shortness of breath is. In fact, sometimes the most severe shortness of breath can be something that’s not life-threatening—like hyperventilation or a panic attack, and the mildest symptoms can be related to serious causes.
Serious causes can be accompanied by other symptoms.
