High Cortisol in Women Over 40: What It Means and What to Do

Cortisol gets blamed for a lot in midlife.

Weight gain.
Poor sleep.
Feeling wired but exhausted.
Hormone symptoms that don’t seem to settle.

If you’ve ever felt overwhelmed by the cortisol conversation online or elsewhere, you’re not alone.

And while it’s true that cortisol plays a role in many of these issues, here’s the part that often gets missed:

Cortisol itself isn’t the problem. It’s actually a hormone we need.

Why Hormone Therapy Can Make Menopause Symptoms Worse (and What to Do Instead)

Bio-identical hormones can be an incredibly helpful tool for many women moving through perimenopause and menopause.

I’ve experienced this personally. For me, bioidentical progesterone was a game changer for my sleep during perimenopause.

But here’s the part that doesn’t get talked about nearly enough:

Hormones aren’t always the first thing that needs to be addressed — and in some cases, adding them too early can actually make symptoms worse.

Let me explain…

Is It Too Late to Lose Weight in Your 40s or 50s? Here’s What Actually Works

There’s a lot more conversation happening now about perimenopause and menopause — and that’s a good thing.

But I also hear something different from many of the women I work with who are past that stage.

“I wish this had been talked about more when I was going through it.”

“I struggled for years and didn’t feel like I had any real options.”

If that’s you, this is what I want you to hear…

A few things I’m ready to leave behind in 2025…

The end of a year and the start of a new one naturally invites reflection. It always makes me think about the passage of time - where I am relative to where I’d like to be, and how I want my life and health to feel moving forward.

As we head into 2026, there are a few things I’m ready to say goodbye to, especially in the world of women’s health.

Here are three of them…

My Joyful Holiday Gift to You

I know this is an incredibly busy time of year. It can feel like a whirlwind, but I hope it also holds some peaceful moments when you’re able to pause, take in the lights, and remember what truly matters.

I am so grateful for this community. Thank you for taking the time to read these messages and for allowing me to share my thoughts and a bit of my life with you.

As we head into the holidays, I want to offer a gentle reminder that doing what brings us joy is an important part of our health. Most weeks I write about nutrition, movement, hormones, and the habits that help us feel our best. But something I’ve learned over the past few years is how powerful it is to pay attention to what genuinely brings us joy, and then make sure we spend some time doing it.

Why Strength Training is Essential for Hormone Balance in Midlife

This might be a little controversial…

but walking does not count as exercise in the way most women over 40 need it to.

And neither does yoga.

They’re both fantastic forms of movement — they support stress, mobility, mental health, and overall wellbeing. But when it comes to hormonal balance, metabolism, and aging well, they simply can’t do the job on their own.

Why I Was So Tired in My 40s (and What Helped Me Have More Energy Than Ever at 49)

Lately, I’ve been reflecting on something that feels really good to say out loud: I feel happy.

Not the surface kind of happy that comes and goes, but a deep sense of contentment. I feel good in my body, energized about what’s ahead in my business, and more present with my family.

But that’s not the way it’s always been.

“My Blood Work is Normal, But I Feel Terrible” - Here’s Why…

You deserve so much more than the line of “fine.”

Lately in my stories, I’ve been talking about how often women are told they’re “fine” — especially with blood work — even when they absolutely don’t feel fine. This message has resonated deeply with so many of you, and honestly, I’m not surprised. I hear this every single week in my practice.

And yes… normal ranges matter. It’s good news when nothing is drastically abnormal.

But normal doesn’t mean optimal — and it definitely doesn’t guarantee that you feel energized, rested, or like yourself.

This is the secret to success — in workouts and in life

Not every workout feels great. Not every meal you cook will be perfect. Some days you won’t reach your water goal or get all your steps in. But there’s incredible value in showing up anyway.

That’s been a theme I’ve talked about a lot lately — how the simple act of showing up for yourself builds momentum. Whether it’s in exercise, nutrition, or any other area of your life, consistency — especially when it’s inconvenient or imperfect — is what creates lasting change.

A haunted house… but it’s your hormones

A haunted house… but it’s your hormones

A haunted house… but your doctor says your hormones “look fine” — even though you’re exhausted, snapping at everyone, and every joint in your body aches.

A haunted house… but you wake up at 3 a.m. haunted by your racing mind, hot flashes, and a sudden urge to reorganize your entire life.

A haunted house… except the habits and programs that used to help you feel your best — or lose weight — just don’t seem to work anymore.

Sound familiar?

Forward momentum beats perfection

Some days it feels like I’ve got it all together. Other days… not so much.

And the truth? There’s no such thing as perfect balance.

Here’s what I mean:

The other day, I was feeling pretty good. I’d gotten up early for a strength workout, did some patient consults and finished up charts, posted on social media and answered messages, even squeezed in a trip to the Farmer’s Market with the kids. By dinnertime, I thought: I’m on top of it today.
