shortness of breath-causes
Final Cause of Shortness of Breath: Lack of Oxygen in the Air. Sometimes, there's just nothing you can do to make things better. At high altitudes, the air is too thin to contain an adequate supply of oxygen for the body's needs.
Most cases of shortness of breath are due to heart or lung conditions. Your heart and lungs are involved in transporting oxygen to your tissues and removing carbon dioxide, and problems with either of these processes affect your breathing. A number of other health conditions also can make it hard to get enough air.
Emphysema Emphysema is a chronic lung condition that causes shortness of breath, a chronic cough, wheezing, and more. Atrial fibrillation Atrial fibrillation is a heart condition that causes heart palpitations, confusion, dizziness and more.
