Throughout pregnancy, a woman’s body experiences major changes as it supports the growth of a new life.  But pregnant women face a number of challenges. One of which is the need to maintain optimal levels of essential nutrients like iron. Low iron in pregnancy, is a common condition that needs carefully handling. To safeguard both the health of the woman and the unborn child.

Importance of Iron in Pregnancy

A necessary mineral, iron is essential to the body’s capacity to carry oxygen and generate energy. Because iron is needed to support the growth and development of the fetus, placenta, and maternal tissues. The requirement for iron rises significantly during pregnancy. Hemoglobin, the protein in red blood cells that transports oxygen from lungs to body’s tissues, is formed only with iron. Additionally, it promotes the baby’s brain growth and keeps the immune system functioning normally.

Causes of Low Iron in Pregnancy

The following are some causes that can lead to iron deficiency anemia during pregnancy:

Increased Iron Requirements:

Because of the increased volume of blood in the mother and the increasing demands of the growing fetus. The body requires much more iron during pregnancy.

Inadequate Dietary Intake:

Poor eating habits and restrictive food patterns creates insufficient iron stores in pregnant women. Maintaining appropriate iron levels requires consuming foods high in iron. Those foods include lean meats, beans, chicken, fish, lentils, tofu, fortified cereals, and dark leafy greens.

Blood Loss: 

Pregnancy itself, can result in significant blood loss, especially during childbirth. Iron deficiency anemia is more common in women who suffer from excessive menstrual flow or problems during pregnancy and childbirth.

Multiple Pregnancies:

Iron deficiency is more common among women carrying multiple pregnancies, such as twins or triplets. Because they have higher iron requirements.

Gastrointestinal Disorders: 

The body’s capacity to absorb iron from meals can get hampered by conditions like gastric bypass surgery, inflammatory bowel disease. And celiac disease, which can result in deficits.

Chronic Illnesses: 

Long-term ailments, like heart failure, renal disease, and autoimmune diseases, can affect how iron gets metabolized. And increase iron deficiency anemia.
