Shortness of Breath
Hemoglobin allows your RBCs to transport oxygen around the body. Oxygen levels will also be low when your hemoglobin levels fall due to the deficiency of iron deficiency. This means your body cells and tissues won’t get adequate oxygen to carry out regular activities, such as walking, running, etc. Consequently, there is a marked increase in your breathing rate as your body strives to get more oxygen – leading to shortness of breath.
The intensity of this sign depends on the levels of iron in your body and the amount of work you have done. The lower the iron stores of your body, the quicker and more severe you will experience shortness of breath. If you find yourself breathless doing regular, daily tasks that you managed easily, such as working out or climbing stairs, iron deficiency could be to blame.
