HRT & GLP-1 Q&A: Progesterone Problems, Hair Loss, Weight Gain, and More

The Hormone Solution | Menopause, Perimenopause, & Women's Midlife Health

What do you do when you finally start HRT and instead of feeling amazing, you feel exhausted, puffy, bloated, or like something is just not right? Or you start a GLP-1, lose weight, and suddenly your hair starts falling out? Today’s episode is another listener Q&A, and we are getting into the real-life questions women are asking when hormone therapy, thyroid treatment, weight-loss peptides, and menopause symptoms do not fit neatly into a textbook. We talk about progesterone intolerance, oral versus topical progesterone, when estradiol may still be too low even though your doctor says...

GLP-1s and Menopause: What Every Woman Over 40 Needs to Know

The Hormone Solution | Menopause, Perimenopause, & Women's Midlife Health

You cannot open your phone anymore without hearing about Ozempic, Wegovy, Mounjaro, Zepbound, retatrutide, and before-and-after transformations. One person says GLP-1s are the greatest thing ever. Another says they are going to destroy your health. As usual, the truth is somewhere in the middle. In this episode, I break down GLP-1s specifically through the lens of perimenopause and menopause, because midlife women are dealing with a completely different metabolic landscape. Estrogen is changing. Muscle is easier to lose. Insulin sensitivity may be shifting. Sleep is falling apart. Belly fat is...

Estrogen Dominance Explained: What Every Woman on HRT Needs to Know

The Hormone Solution | Menopause, Perimenopause, & Women's Midlife Health

If you are taking HRT, it is not enough to only ask how much estrogen you are using. You also have to ask a second question: how well is your body actually processing and clearing that estrogen? In this episode, I sit down with David Roberts and John Gilday from Mara Labs to unpack estrogen metabolism, estrogen receptors, environmental hormone disruptors, detoxification pathways, and why the conversation around “estrogen dominance” is often way too simplistic. We talk about the difference between having high estrogen and having estrogen that is not being metabolized efficiently, especially...

Your Body Isn’t Broken: Why Doing More Can Make Midlife Worse with Debbie Potts

The Hormone Solution | Menopause, Perimenopause, & Women's Midlife Health

Have you ever felt like you are doing everything right and your body is just not cooperating? You are eating well, exercising, tracking your protein, fasting, taking supplements, getting your steps in, and still gaining weight, feeling exhausted, sleeping poorly, and wondering why the strategies that used to work suddenly do not anymore. In this episode, I sit down with Debbie Potts to talk about what may actually be happening when healthy habits become unhealthy stressors. We get into the connection between the nervous system, metabolism, hormones, muscle, recovery, under-fueling,...

Are You Actually Optimized on HRT? The Levels, Doses, and Symptoms That Matter

The Hormone Solution | Menopause, Perimenopause, & Women's Midlife Health

How do you know if your HRT is actually optimized? Not just enough to stop a hot flash, but enough to support your bones, brain, mood, metabolism, sleep, sexual health, and overall quality of life? In this episode, I break down one of the most confusing parts of hormone replacement therapy: dose, levels, and symptom response. Because the old-school advice to simply use the lowest dose possible until your symptoms disappear does not tell us the whole story. At the same time, more is absolutely not always better. We dig into what the research actually tells us about estradiol dose and brain...

GLP-1s, Skinny Culture, and the Question Every Woman Should Ask Herself with Natalie Jill

The Hormone Solution | Menopause, Perimenopause, & Women's Midlife Health

Something happened after my conversation with Natalie Jill on her podcast, Midlife Conversations. Women flooded my inbox and my community, not with questions about dosing or side effects, but with something closer to relief. They finally felt heard. That reaction told me this conversation needed a second chapter, so I'm bringing you the rest of it here, along with some of the raw, honest messages from women in my community who are done being quietly shamed for a choice that has changed their health and their lives. In this episode, Natalie and I go back to where it all started. We talk about...

The Dark Side of GLP-1s No One Is Talking About

The Hormone Solution | Menopause, Perimenopause, & Women's Midlife Health

Karen Martel grew up with a front row seat to diet culture most of us only felt secondhand. Her mom didn't just live it, she ran a weight loss center. Butter was called Vaseline. Popcorn was the enemy. And by her teenage years, Karen was deep in an eating disorder that would shape her relationship with food for decades. In this conversation, Karen gets honest about that history, and about something she still checks herself on today. Because here's the twist. We told ourselves we moved past the thin obsession. Body positivity was supposed to be the turning point. But somewhere in the last two...

More Episodes

You've been told menopause is a hormonal transition. It's also a vascular one, and almost nobody is talking about it.

In this episode, Karen sits back down with Cathy Eason, Chief Science Officer at Berkeley Life, for round two on a molecule most women have never heard of but should know by heart: nitric oxide. It is tiny, it is a gas, and it touches nearly every system in your body. When estrogen drops in perimenopause and menopause, nitric oxide production drops right along with it, and that decline may be quietly connected to your fatigue, your brain fog, your blood pressure, your blood sugar, and yes, your libido.

Karen and Cathy get specific about the vascular side of midlife that rarely makes it into the conversation. That includes what nitric oxide has to do with responsive desire versus spontaneous desire, why heart disease risk climbs even in women who feel healthy, and what your labs might be trying to tell you before anything feels obviously wrong. Cathy also shares a personal story involving her spouse's vascular event that reframes how seriously women need to take this.

This one connects a lot of dots. If you've ever felt like your energy, your desire, and your health markers were somehow all falling apart at once with no clear explanation, this episode is going to make a lot more sense of it.

In This Episode, We Cover:

What nitric oxide actually does in the body and why it touches nearly every organ system
The direct link between declining estrogen and declining nitric oxide production
Why fatigue is the number one reported symptom in perimenopause and menopause, and the physiological reason behind it
How nitric oxide affects blood sugar, digestion, and insulin sensitivity
The connection between nitric oxide, brain fog, mood, and sleep
Why responsive desire is normal for most women, and what blood flow has to do with it
What time of day your circulation actually peaks, and why that matters for sex
The lifestyle habits quietly depleting your nitric oxide without you realizing it
What labs and at-home tests can hint that you're running low
A personal story about a spouse's vascular event and why women need to take heart health seriously now, not later

Who This Episode Is For

This episode is for the woman who has been chasing energy, sleep, and libido fixes without ever hearing about the blood flow piece. It's for anyone who has been told her labs are normal but she still doesn't feel like herself. It's especially relevant if you're on HRT and not getting the full results you expected, or if heart health has never really been on your radar because you don't have metabolic disease. If you've noticed cold hands, brain fog, low energy, or a sex drive that disappeared and you've been chalking it up to just getting older, this conversation is for you.
