Iron is essential for the body as it plays a pivotal role in many critical functions. This includes boosting the immunity, maintaining cardiovascular health and aiding cognitive development. Approximately 70% of iron is found in the red blood cells (hemoglobin) and muscle cells (myoglobin). It is extremely important to the transporting of oxygen through red blood cells to various parts of the body. Lack of iron in the blood can occur due to poor diet, blood loss, or the inability to absorb iron through foods. Many people do not know when they have insufficient iron in their blood. This can lead to various complications. This problem is easily treated, if they know the signs to look out for.

An iron deficiency can cause a myriad of symptoms. The most prevalent is lethargy or fatigue. Other low iron symptoms include shortness of breath and changes in the appearance. Most often, the symptoms of iron deficiency differ according to its severity. It may also differ between children and adults.

Low Iron Symptoms in Children

There are many reasons for children to suffer with iron deficiency. Apart from a poor diet and the inability to absorb iron from foods, iron deficiency in children may also occur due to long-term slow, blood loss and rapid growth.

Women lose more blood than men because of their monthly period and also during child birth. They may also lose iron during pregnancy and breastfeeding as these nutrients are transferred to the baby. Young women, aged 14 to 18, require at least 15mg of iron per day. Women over the age of 19 through 50 require 18mg while pregnant women may require approximately 27mg of iron. Adult men, however, only require approximately 8mg of iron per day. However, men too suffer with the symptoms of iron deficiency.
