Iron Deficiency In Pregnancy

Iron deficiency is one of the most common medical issues during pregnancy – yet many women are told their symptoms are simply a “normal part of being pregnant”.

At The Iron Infusion Clinic, Dr Joel Collins and our specialist-led team regularly care for women experiencing iron deficiency during pregnancy, helping restore iron levels safely and effectively.

Why is iron deficiency so common in pregnancy?

Pregnancy places enormous demands on the body’s iron stores.

Even women who begin pregnancy with normal iron levels can become iron deficient as pregnancy progresses. In fact, up to 80% of women will develop iron deficiency during pregnancy.

There are two major reasons for this:

Your body needs iron to support the growth and development of your baby
Your blood volume increases by approximately 30–50% during pregnancy, requiring large amounts of iron to produce additional blood

As a result, iron requirements increase dramatically:

Around 200% higher than normal during the second trimester
Around 300% higher during the third trimester

Symptoms of iron deficiency in pregnancy

Many symptoms of iron deficiency overlap with symptoms commonly attributed to pregnancy itself.

These can include:

Fatigue and exhaustion
Headaches
Restless legs
Leg cramps
Reduced energy and exercise tolerance
Difficulty coping physically during pregnancy

For many women, correcting iron deficiency can significantly improve these symptoms and overall quality of life during pregnancy.

Why treating iron deficiency matters

Iron deficiency during pregnancy affects more than just the mother.

Research shows that if a woman’s ferritin (iron stores) is low at the time of delivery, her baby is also more likely to be iron deficient at birth. Babies rely on maternal iron stores throughout pregnancy.

Low iron during pregnancy has also been associated with:

Difficulty establishing breastfeeding
Poorer recovery after delivery
Increased fatigue during the postpartum period
Reduced ability to cope with sleep deprivation and the physical demands of caring for a newborn
Lower mood after delivery

Having adequate iron stores before delivery is important for both maternal wellbeing and infant health.

Why iron tablets often struggle during pregnancy

Because iron requirements in pregnancy are so high, oral iron tablets are often insufficient to adequately restore iron stores.

Iron tablets can also cause side effects, particularly constipation – something already very common during pregnancy.

For this reason, many pregnant women benefit from intravenous iron therapy (iron infusion), particularly from the second trimester onwards.

Iron infusions during pregnancy

At The Iron Infusion Clinic, we routinely provide iron infusions for pregnant women from approximately 12–14 weeks gestation onwards when clinically appropriate.

Iron infusions:

Rapidly replenish iron stores
Avoid many of the gastrointestinal side effects of tablets
Are often effective within 1–2 weeks
Can be particularly important when delivery is approaching and there is insufficient time for tablets to work

Iron tablets may take 4–6 months to significantly improve iron stores. Pregnancy often does not allow that timeframe.

Our clinic has extensive experience providing iron infusions during pregnancy, with thousands of pregnant women treated safely through our service over many years.
