Hormone Therapy and Mounjaro: Finding Balance in Midlife

We’ve finally hit a point in history where women in midlife have options. Not one-size-fits-all advice like “watch your portions” or “just walk more”, but actual tools that work.

For hormone balance in menopause, we have MHT(menopause hormone therapy). For insulin resistance, metabolic shifts, and weight that won’t budge? GLP-1 medications like Mounjaro are changing the landscape. And there are supplements and other medications for the ones who cannot or don't want MHT.

But when you’re using both at the same time, questions come up. Some women feel amazing. Others feel like they’re unraveling. Most are somewhere in between, adjusting, adapting, and learning. This post is about that middle ground. The balance. The benefits, the challenges, and the real experiences behind the science.

When the Combo Works: MHT + Mounjaro as a Power Team

Used together, MHT and Mounjaro can support the body in ways that feel almost revolutionary for women in their 40s, 50s, and beyond. Many women report:

Better sleep and fewer hot flashes
Less food noise and more stable energy
A drop in inflammation and visceral fat
Relief from anxiety, brain fog, and metabolic chaos

That’s not a promise, it’s a possibility. And for a lot of us, it’s real. When these therapies are working well, it feels like you finally have your footing. You can think clearly. You eat because you're hungry, not because you're chasing dopamine. You move more freely. You rest better. And most importantly, you stop fighting your body.

It happened to me, and I am sure it happens to a lot of women out there. It took me months to stabilize myself and feel better, so please don't lose hope. It takes time for your body to adjust.

Listening to the Subtle Shifts

Of course, not everyone has the same smooth ride. Some women, myself included, start to notice subtle shifts after combining weight loss medication with hormone therapy. At first, they’re easy to ignore: a little spotting here, a foggy morning there. But over time, it becomes clear something’s changed.

If you’re on both treatments, watch for signs like:

Unexplained spotting or bleeding
A return of hot flashes or night sweats
Mood swings, irritability, or anxiety
Breast tenderness, insomnia, or fatigue
Lab tests showing lower estradiol or progesterone

These changes might not be your imagination, or your hormones “just acting up.” They may be a sign that your body isn’t absorbing what it used to.

The Many Faces of Menopause: Symptoms No One Warned You About

What GLP-1s Do To Your Digestion (and Why It Still Might Affect MHT)

GLP-1 medications like Mounjaro work in part by slowing gastric emptying, meaning food and anything you swallow moves through your stomach more slowly. This helps with appetite and blood sugar control, but it can also affect how your body absorbs medications. It’s commonly assumed that only oral estrogen and progesterone are impacted, but many women are discovering that’s not the full picture.

While oral MHT can become less effective due to delayed or inconsistent absorption, some women on transdermal estradiol (patches, creams, gel, or sprays) also report a significant drop in hormone levels. In these cases, the issue isn’t digestion; it may be changes in skin absorption, blood flow, or metabolic rate influenced by the medication itself.

So if you're taking:

Oral estradiol → estrogen levels may drop unexpectedly
Oral progesterone → your uterine lining might not be fully protected
Transdermal estradiol (patch/spray/gel) → may require dose adjustments to stay effective
Birth control pills or other oral meds → timing and dose may need to be re-evaluated

You may find yourself wondering: “Why am I bleeding again when I’ve been stable for months?”
This happens to many women. Sometimes, hormone levels tank, despite no change in dose or method, and symptoms like bleeding, hot flashes, and mood swings return.

There aren’t many published studies yet on how GLP-1s affect transdermal or non-oral hormone delivery. However, the British Menopause Society’s 2025 guidance on incretin-based therapies acknowledges the potential for interaction and the need for individualized adjustments to MHT and even birth control pills.

Some doctors may even suggest stopping the GLP-1 altogether, or getting off the MHT. But with the right monitoring and dose adjustments, many women find they can continue both therapies safely and effectively.

Ways to Keep Things in Sync

The good news? You don’t have to give up either therapy. You may just need to fine-tune things a little. Here are some strategies to explore with your doctor:

Consider switching formats:

Use estradiol patches or gels (transdermal = no stomach absorption needed). Change the location of the estradiol patch, instead of applying it on your tummy, place it on the hip, or buttocks.
Try vaginal progesterone for more direct endometrial protection or talk to your doctor if an IUD, like Mirena, with progesterone might be a better option for you.

Keep an eye on your body:

Track symptoms like bleeding, fatigue, hot flashes, mood shifts
Ask for bloodwork 4–6 weeks after starting or adjusting your routine
If you’re bleeding postmenopause, get an ultrasound to check your uterine lining.

You’re not looking for perfection, you’re looking for consistency, comfort, and a sense that your treatment is actually working for you.

Don’t Forget the Gut: Constipation and Sluggish Digestion

GLP-1s slow digestion. That’s not a side effect, it’s part of how they work. But the downside? Constipation. It happened to me and I bet it happens to a lot of people. Combine that with a lower appetite, a high-protein diet, and possibly hormone fluctuations, and you’ve got a recipe for gut frustration.

Here’s what helps many women (myself included):

Psyllium husk in water or smoothies
Cooked vegetables like broccoli, spinach, zucchini
Berries, flaxseed, chia
Magnesium citrate before bed
Drinking enough water, even when you’re not thirsty

It’s not glamorous, but it matters. A backed-up digestive system can make everything feel worse, your mood, your sleep, your absorption, even your motivation to eat healthy.

You’re Not Doing It Wrong- You’re Just Paying Attention

Here’s the part no one says: you are your own data set. Most doctors aren’t trained in both menopause and metabolic health. They may not know how to help you fine-tune this combo. But you can observe, track, adjust, and advocate. You’re not failing. You’re experimenting. And that’s exactly what this phase of life requires.

Whether things are working beautifully or you’re still trying to figure it all out, you’re allowed to ask questions. You’re allowed to change course. And you’re allowed to expect more from the medications that are supposed to support your health.

MHT and Mounjaro can absolutely work together, and when they do, the results can be transformative. But finding that balance takes awareness, flexibility, and sometimes a little patience.

If you're navigating both right now, know this: You're not alone. You're not broken. And you're not imagining it.

You’re learning how to support your body in a way the medical world is still figuring out. But every woman who tracks her symptoms, asks questions, and refuses to be dismissed is helping change that. One story at a time, we’re pushing the system forward.
