Shortness of Breath
Iron deficiency anemia leads to a low level of hemoglobin in the red blood cells. Since these proteins are responsible for providing oxygen for your lungs, this problem would affect the activities of your respiratory system. The muscles in these organs will not have sufficient oxygen to perform normal tasks. As a result, you would feel shortness of breath even when doing some simple things like, climbing stairs, walking, or jogging. The breathing rate would also increase to compensate for the deficiency of oxygen. [4]
