Episode 003 — PMS, Histamine & Hormones: What’s Really Going On?

There’s a viral trend going around — women taking Zyrtec, Claritin, and Pepcid before their periods and reporting that their PMS and PMDD symptoms are dramatically better. And honestly? It’s working. But why?

In this episode, I break down the real reason antihistamines are helping — and what it’s actually telling you about what’s going on inside your body. Because the trend is onto something. It’s just not the whole story.

We cover:

• How estrogen and progesterone directly control histamine release — and what happens when they fall out of balance

• Why histamine isn’t just an allergy problem — and how it drives mood swings, anxiety, bloating, and migraines

• The feedback loop that keeps symptoms stuck and makes them worse over time

• Two key genetic variants that explain why you might struggle more than your sister, your friend, or the woman next to you

• What a root cause approach actually looks like — and where antihistamines fit in

Whether you’re in your 30s dealing with PMDD or in your 40s wondering why perimenopause is hitting differently than you expected — this episode will give you a framework for understanding what’s really going on, and what’s worth addressing first.

Just like a roadtrip, you’ve got to know where you’re starting from, where you’re going and what you’ll encounter along the way.

In this episode of Her Genetic Edge Podcast I break down 5 things to consider before you start your journey.

In this episode I share how both my patients and I have been using Mira for quick and easy hormone monitoring at home. Mira provides 20% off when you use our affiliate code 2AIKMANL20 at https://shop.miracare.com/. I personally use the Ultra4 Kit for Perimenopause.

You’re not failing. And your body isn’t broken.

What works for one woman doesn’t always work for another, because hormones are only part of the picture. Your genetics influence how your body processes hormones, responds to stress, handles inflammation, and navigates the hormonal shifts of midlife.

In this episode, we’ll explore why midlife often exposes patterns the body could compensate for before, why HRT is not one-size-fits-all, and how understanding your genetics can help you make more informed, personalized decisions about your health.

You’re gaining weight even though you’re doing everything the same. You’re losing your patience and getting triggered in a way that’s out of character for you. Not to mention your hair is thinning, you can’t sleep, can’t focus and fatigue feels like an understatement. 

You’re of that age so it’s got to be your hormones. Off to the doctors you go.

Only to be told your bloodwork is still “within normal limits.” And that what you’re experiencing is expected for your age.

If you’re a woman in midlife you might know this scenario all too well.

As both a nurse practitioner and a woman in my 40s navigating this personally, the pattern I’ve seen is that midlife often exposes patterns the body was compensating for before.

When we’re younger, hormones provide a bit of buffer.

Higher levels of estrogen, progesterone, and testosterone can help the body be more resilient. But as our hormones begin to fluctuate and decline during perimenopause and menopause, imbalances that may have been in the background can suddenly become much more noticeable.

This may explain why you suddenly don’t feel like yourself anymore. It’s not all in your head.

The Gap I Kept Seeing in Medicine

I’ve been in practice since 2011. Early in my career, I worked in the hospital setting before transitioning into traditional outpatient medicine because I wanted to help keep people out of the hospital.

But I quickly realized there was a major gap between what I had been trained to do… and what was actually helping patients feel better.

I was the provider telling women “Everything looks normal.”

Which translates to I don’t have an answer for your symptoms. 

After seeing woman after woman presenting with this same scenario I knew something deeper was going on.

Day after day, I saw women walking into my office saying:

• “I think it’s my hormones.”

• “I can’t sleep.”

• “I’m anxious all the time.”

• “I’m losing my hair.”

• “I feel inflamed.”

• “My body feels different.”

And I knew this wasn’t just women being dramatic.

Searching for answers eventually led me into functional medicine, a more root-cause approach focused on understanding why symptoms are happening rather than simply suppressing them.

But Even Functional Medicine Wasn’t Explaining Everything

After a few years of using functional lab testing in practice, like DUTCH testing, gut testing, organic acids, and advanced bloodwork analysis, I noticed another pattern.

Some women improved dramatically.

Others didn’t.

Sometimes two women would follow nearly identical protocols and have completely different results. One would feel amazing while the other barely improved… or improved temporarily before symptoms returned.

Again, I found myself asking what was missing. 

Everything changed when we began looking at genetics first.

Why Two Women Can Take the Same Hormones and Feel Completely Different

Genetics influence how your body:

• processes hormones

• responds to stress

• handles inflammation

• detoxifies

• produces energy

• and adapts during midlife changes

This is why two women can take the exact same HRT regimen and have completely different experiences.

One woman may feel incredible.

Another may still struggle with:

• sleep

• anxiety

• inflammation

• weight gain

• mood changes

• fatigue

• or persistent symptoms

The difference is often not that one woman is “doing it right” and the other isn’t.

It’s that their bodies are wired differently.

And when we started looking at those genetic patterns, so many things finally began to make sense.

We could see where someone’s bottlenecks were.
We could understand why certain protocols worked beautifully for one person but not another.
And probably the most important, these women could finally stop blaming themselves.

Personalization Matters More Than Ever in Midlife

We are entering a completely new era in women’s health.

After years of fear surrounding hormone replacement therapy following the WHI study in the early 2000s, more women are now seeking HRT support, and newer research is showing us that hormones are safer and more beneficial than many women were once told.

And I’m a huge believer in supporting women through midlife with hormones when appropriate. (I’m on HRT personally).

But one-size-fits-all medicine still doesn’t work.

Because hormones are only part of the picture.

How your body processes those hormones matters too.

This is why I created Her Genetic Edge, to bridge the gap between conventional medicine, functional medicine, genetics, and the hormonal changes women experience in midlife.

Because women deserve more than being told: “Everything looks normal.”

You deserve to understand why your body responds the way it does.

And more importantly:
You deserve a more personalized approach to feeling better.

Your body is not broken.
It may simply need a more personalized roadmap.

The seemingly sudden drop in estrogen and progesterone can be quite destabilizing. Everywhere you turn, someone is giving you the strategy that will reverse all your symptoms. Just take the HRT, eat all the protein, do you’re weighted-vest workouts, and don’t forget your cupful of supplements.

So why isn’t it working for you? Especially when it seems to be working for everyone else? The answer may be in your genetics!
