RED-S and the Long-Term Implications on Pregnancy

Date: July 2025

🏃‍♀️💔 We often talk about RED-S (Relative Energy Deficiency in Sport) in terms of performance and fertility.

But there’s something even more important to consider:

its lasting effects on pregnancy and your baby’s health.

When your body isn’t getting the fuel it needs, your hormones shift.

And that delicate balance is vital for conception and carrying a healthy pregnancy.

Without it, risks increase, like:

• Miscarriage or preterm birth
• Babies not growing as expected
• Pregnancy complications like hypertension and preeclampsia

Here’s why. RED-S doesn’t just affect your cycle. It impacts the quality of your uterine lining, how well the placenta develops, and how your blood vessels function — all of which are essential for a healthy pregnancy.

One study published in Sports Medicine (2019) confirmed it.

RED-S can have effects that reach far beyond the track or the field.

That’s why we need to act early.

Caring for RED-S isn’t just about helping athletes compete at their best.

It’s about helping them thrive as future parents too.

And that’s my focus.

I work with elite female athletes to optimise their preconception health through a blend of sports medicine and personalised obstetric care.

Together, we:

• Detect energy deficiency before it becomes a risk
• Restore hormonal health and metabolic function
• Strengthen uterine and placental health
• Build pregnancy-safe plans tailored to each athlete’s unique needs

Because preparing for motherhood starts well before the first positive test.

Let’s connect and create a plan to support your athletes now and their growing families in the future.
