Hemoglobin is a protein that oversees carrying oxygen to the blood of vertebrates, and one of the crucial elements that make up hemoglobin is iron. So what exactly happens when someone does not have enough iron in their blood? Low iron, also known as iron deficiency anemia, can cause tiredness, tightness in the chest, and paler skin, to name a few symptoms.
People who have an increased risk of anemia are women, especially during their monthly periods and labor. In addition, children between the ages of one to two have growth spurts and need more iron in the body to support them. The elderly (to be more specific, those over the age of 65) are prone to anemia because they typically do not have enough iron in their diets and can develop chronic diseases. These are only a few examples of people who may develop anemia, but this list is not limited as there may be other cases that have not been mentioned here.
