Shortness of Breath in Adults
So far you have indicated that you are more short of breath with exertion without wheezing, symptoms of infection or signs of anemia.
People who have not been physically active by choice or for medical reasons can become "deconditioned." In addition to decreased stamina, shortness of breath even with relatively little exertion can occur. Significant weight gain can also be the sole cause of new shortness of breath.
Make an appointment with your doctor.
