I Started HRT in perimenopause. Why Am I Still Gaining Weight?
“I finally got on hormones. My hot flashes are better. I’m sleeping again. So why is the scale still going up?”
I see some version of that question on social media almost every day.
If this is you, I want to tell you something…
You didn’t do it wrong. Your hormone therapy is doing its job. It was just never the job you were told it would do.
Why it seems like HRT should handle it
The weight showed up when your hormones changed. So putting the hormones back should send the weight packing. Makes sense, right? Well, partially.
Hormone therapy (you’ll see it called HRT or MHT) does so much. It’s more than hot flash relief. It matters for your bones, your brain, and your heart, everything that keeps you strong for the next 30 years. I love mine, and I’m not giving it back!
When I started my hormones, my symptoms calmed down (thank goodness), but my weight didn’t change. So I went looking for why.
Meet the Hormone Hierarchy
When it comes to addressing weight gain, sequence matters. I teach it as a tree. (Probably because my Dad is a forester and I grew up walking the woods with him.) So I want you to picture a big beautiful tree in summer.
- The canopy is estrogen, progesterone, and testosterone. These are the leaves, the flowers, and the fruit. They’re the hormones everyone talks about, and they’re where hormone therapy does its work.
- The trunk is your thyroid and DHEA. It carries energy from the roots up to everything above.
- The roots are cortisol, insulin, and melatonin. In plain terms, that’s your stress, your blood sugar, and your recovery. These three drive your metabolism every single day.
As every gardener knows, a tree grows from its roots up. It never grows from the leaves down.
What happens when only the canopy gets attention
Hormone therapy gives back to the canopy. That’s why, for so many women, the hot flashes ease and the fog starts to lift and mentally you feel better.
But the roots are a different story. And the roots drive your metabolism. You’ll always have a hard time losing weight without focusing here:
- Cortisol (your stress). Say your stress has been running high for years. Your body reads that as danger, and a body in danger holds on to its fuel, aka fat.
- Insulin (your blood sugar). Say your blood sugar has been drifting, and insulin is working overtime to keep up. More of what you eat can get stored, and a lot of it lands around your middle.
- Melatonin (your recovery). Say you’re sleeping better than before, but still tired. Your hunger signals turn up and your fullness signals turn down.
None of that lives in the canopy. So you can have beautiful hormone levels on paper and a metabolism that’s still taking its orders from the roots.
That’s not a willpower problem. It’s the order your body works in.
Every woman’s mix is different. Want to know what’s driving yours? Take the quiz.
Roots first, so the canopy can do its job
This isn’t hormones versus lifestyle. Hormone therapy is one tool in the toolkit, and no tool is the whole strategy. But the roots need to be addressed too. And it’s never too late to go back and take care of them.
It’s also not a reason to stop your hormones. That decision belongs to you and your doctor.
What it means is that the next question isn’t “do I need a higher dose?” It’s “what’s happening at my roots and what can I do to nourish them.”
What’s driving yours?
So what is that number on the scale trying to tell you?
I built a quiz for this exact question. It’s called What’s Driving Your Midlife Weight Gain? You answer some questions about your sleep, your stress, your energy, and your cravings, and it shows you which pattern looks most like yours.
Think of it as a first look at what’s going on underneath.
