A Woman’s Need for Iron Throughout Her Life

In honour of International Women’s Day (March 8th), I thought it was fitting to make today’s post all about the ladies. Did you know that simply being female puts you at a higher risk for developing iron deficiency?

It is estimated that 20% of women of childbearing age are iron deficient and 50% of pregnant women develop iron deficiency. Each life stage can bring about different causes (or types) of the condition, which include:

  • Increased blood volume
  • Blood loss
  • Reduced absorption

Let’s have a look at the risk that each stage of life brings with it and why…


Age 0 to 3: Growth Spurts

Think of a baby or toddler – it’s unbelievable how quickly they seem to grow, right? Well, a rapidly growing body means an increasing blood volume and an amplified need for iron to accommodate the growth spurts that happen between 0 to 3 years of age.


Age 10 to 14: Puberty & Menstruation

During her adolescent years, a girl’s risk of iron deficiency – due to blood loss or increased blood volume – increases. Puberty brings with it rapid growth spurts and menstruation (along with pimples and embarrassing fashion choices). As mentioned above, the body requires more iron to accommodate the higher blood volume during growth spurts. Unless the young lady is getting additional iron through an iron-rich diet or even an oral iron supplement, her iron levels may have trouble keeping up. Add to this the blood lost each month due to menstruation and you’ve got a perfect storm for iron deficiency.


Age 15 to 45: Childbearing Age

We’ve talked about how blood loss due to menstruation increases the risk of iron deficiency. Pregnancy also greatly increases the risk because of increased blood volume. A woman’s body will produce almost 50% more blood during pregnancy to keep up with her body’s growth and provide iron for her baby. Come the final trimester, the baby begins storing iron for the first 6 months of his/her life, and without proper iron supplementation both mother and baby can be at risk.


Age 55+: Golden Years

In a woman’s golden years, blood loss and poor absorption are the most common causes of iron deficiency. Use of a non-steroidal anti-inflammatory drug (NSAID) and aspirin over many years can damage the gastrointestinal tract and cause bleeding. Also, not producing enough stomach acid can interfere with iron absorption. Women in their golden years may also experience decreased appetite and consume a nutrient-poor diet that doesn’t contain enough iron, further increasing their risk of developing iron deficiency. Finally, medications and chronic conditions (which are more common during this stage of life) can also increase the risk.


Triad of Symptoms Related to Iron Deficiency

As you can see, while iron is an essential nutrient to everyone’s diet, a woman’s need to maintain a healthy iron level is pertinent all throughout her life.

It’s never too early to:

  1. Talk to your doctor about your iron status
  2. Get to know the signs and symptoms of iron deficiency
  3. Understand the different iron supplements that are available for adults and the iron formulations that are available for children
