- The first obvious one to mention is the respiratory system (ie the lungs). So if you have asthma or emphysema for example, then this can cause shortness of breath
- The blood system for carrying the oxygen around the body. So if you are anaemic or iron deficient, then this can cause shortness of breath.
- The heart, which is responsible for pumping the blood to the lungs to load the oxygen onto the red blood cells and then carrying it throughout the body. So if you have cardiac failure, then this can cause shortness of breath.
Make sure you see your Doctor to have it properly assessed.
As a general rule, a firm diagnosis of anxiety, depression or any mental illness is only made once the physical causes are ruled out.
