Growing a new life is an amazing journey, but it is also one of the most demanding physical feats the human body can perform. Behind the scenes, your body is working overtime, performing incredible biological shifts to support your growing baby. One of the most massive changes? Your blood volume.

To keep you and your baby healthy, your body must produce up to 30% more blood durante el embarazo.

This dramatic surge requires a massive supply of iron to build new red blood cells. If you do not consume enough iron to fuel this process, you can develop iron-deficiency anemia—a condition where your blood can no longer carry enough vital oxygen throughout your body.

More than just tired: the real toll of low iron

Anemia is incredibly common. In the US, nearly 1/3 of pregnant women will become anemic at some point. The risk peaks during the third trimester, when your blood volume reaches its highest level.

Because pregnancy already comes with a healthy dose of tiredness, anemia often disguises itself as “normal” pregnancy fatigue. However, this hidden oxygen shortage is a serious medical issue, not just standard exhaustion.

Untreated anemia forces your heart to work much harder and deprives your body of oxygen. This drastically increases the risk of delivering a premature or low-birth-weight baby, and can affect your baby’s brain development. For moms, the impact of anemia continues after birth, increasing the risk of postpartum depression and problems with milk supply.

Boost your iron levels

Fortunately, pregnancy anemia is completely preventable and treatable. You can take control of your health and protect your baby by following these 3 core strategies:

  1. Get Screened Early and Often: At week 8 and week 24-28.

Do not assume your fatigue is just a normal part of pregnancy. Ask your healthcare provider for a Complete Blood Count (CBC) test at your very first prenatal visit. Because blood volume peaks later, insist on a second blood screening between 24 and 28 weeks to catch any sudden drops in your red blood cell count.

  1. Take an Iron Supplement Daily through your entire pregnancy: 

Your body’s demand for iron is simply too high to meet through food alone. Commit to taking a daily prenatal vitamin that contains iron. If your doctor diagnoses you with anemia and prescribes a separate iron supplement, take it exactly as directed.

  1. Power Up Your Plate: With every meal.

Fill your diet with iron-rich foods like dark leafy greens, beans, lentils, red meat, and iron-fortified cereals.

  • The booster: Always pair iron with Vitamin C (like oranges, strawberries, bell peppers, or tomatoes) to improve iron absorption.
  • The blockers: Do no consume dairy, calcium supplements, coffee, or black tea at the same time as your iron-rich meals or supplements, as these actively block your body from absorbing the iron.

Advocate for Your Health

Pregnancy anemia is a serious health concern, but it is one you have the power to conquer. Take control of your well-being today: ask your healthcare provider about taking an iron supplement, ask for regular blood tests at each appointment, and eat high-iron foods with foods high in vitamin C. Your energy, your health, and your baby’s future are worth it!
