You've been told your hormone levels are "normal." But what if one blood test isn't telling the whole story?

In the first episode of On the Qynside, Qyn Labs founder and CEO Shilpi Gupta sits down with Dr. Tara Scott, OB-GYN, certified menopause practitioner, and hormone health expert, to explore why hormone testing is more complicated than a single number.

Drawing on more than two decades of experience in hormone health, Dr. Scott shares why hormone fluctuations matter, how traditional testing can miss important context, and why understanding your individual patterns could help change the way we approach women's health.

In this episode, we explore:

• Why "normal" hormone levels don't always tell the whole story
• What a single hormone test can and can't reveal
• The importance of understanding hormone fluctuations during perimenopause
• Why personalized hormone data matters
• The gaps in hormone education and women's healthcare
• What's next for hormone monitoring

Your hormones change. Your understanding of them should, too.

We usually think about hormones as something our bodies produce internally.

But our endocrine system can also be influenced by substances in the world around us.

Some are known as endocrine-disrupting chemicals, or EDCs.

What are endocrine disruptors?

EDCs are substances that can interfere with the body’s hormonal signaling.

Some can mimic the activity of naturally occurring hormones, including estrogen. Others may block hormone receptors or alter how hormones are produced, transported, or broken down.

Chemicals with estrogen-like activity are sometimes called xenoestrogens.

Researchers have identified potential endocrine-disrupting substances in everyday products, including certain plastics, pesticides, cosmetics, fragrances, and household materials.

Does exposure mean your hormones are imbalanced?

Not necessarily.

Scientists continue to investigate how different chemicals affect human health, including the importance of exposure levels, timing, duration, and individual susceptibility.

There is evidence linking some endocrine-disrupting chemicals with reproductive and metabolic health concerns. But it’s an oversimplification to assume everyday chemical exposure is the explanation for common hormonal symptoms.

Small changes that can reduce exposure

You don’t need to replace everything in your home overnight. Consider a few practical swaps:

• Store and reheat food in glass or other food-safe containers instead of heating it in plastic.
• Reduce unnecessary fragrance exposure where practical.
• Wash fresh produce thoroughly.
• Choose personal care and household products with ingredient information you’re comfortable with.

These steps won’t guarantee better hormone levels, but they can help reduce exposure to certain substances.

Knowledge, not fear

Understanding environmental influences is one part of understanding hormonal health.

And it’s worth remembering that hormones are affected by far more than what we put on our skin or store our food in.

Our internal systems play an important role, too.

Estrogen gets a lot of attention, especially when something feels off with our bodies. But estrogen isn’t the enemy. In fact, it’s essential to everything from our menstrual cycles and bone health to our brain, skin, and cardiovascular health.

So what happens when estrogen and other hormones aren’t working together as expected?

What is estrogen dominance?

You may have heard the term estrogen dominance, particularly in conversations about PMS, heavy periods, and perimenopause.

It’s a term commonly used in functional medicine to describe situations where estrogen’s effects are relatively strong compared with progesterone.

It’s important to understand that estrogen dominance isn’t a formally recognized medical diagnosis. But the relationship between estrogen and progesterone is very real.

Estrogen helps build the uterine lining during the first half of the menstrual cycle. After ovulation, progesterone rises and helps regulate that lining.

When ovulation becomes irregular, progesterone production may decrease, changing the way these hormones interact.

Can your estrogen levels be normal?

Yes. Hormone levels naturally fluctuate throughout the menstrual cycle, and a single measurement may not tell the whole story.

A result that appears normal on one day doesn’t necessarily explain what was happening earlier in your cycle or how your hormone patterns may be changing over time.

This is particularly relevant during perimenopause, when estrogen can fluctuate significantly and ovulation may become less predictable.

Understanding the bigger picture

Rather than focusing on whether estrogen is simply high or low, it can be more useful to understand your hormone levels in context. Where are you in your cycle? Are you ovulating regularly? What symptoms are you experiencing? Have those patterns changed? Because when it comes to hormones, context matters just as much as the numbers.
