The scientists who studied dyspnea in-depth have determined the causes of this illness. If the person has pulmonary diseases, he or she is under the greater risk of facing dyspnea too. Other factors which should be considered while treating dyspnea are the possible heart failure, ischemic heart disease (IHD), hypoxia, problems with metabolism, and different problems with the lungs (e.g. kyphoscoliosis).  The diagnosis should be based on the category of causes.
