Dyspnea: Shortness of breath can be from several causes, heart and lung issues are first, such as asthma, heart failure, etc. It is can also be secondary to stomach problems, such as gastritis and acid reflux. Chronic nasal congestion from allergies can also cause shortness of breath. Anemia is also another cause, the list is endless.
