If I only have osteopenia, not osteoporosis, am I okay? No, you’re still at risk.

When we talk about fracture risk, most people think of osteoporosis. But the numbers tell a different story. Because osteopenia is so common, more than half of hip fractures in women occur in those with osteopenia, not osteoporosis. The risk isn’t only at the extreme. It lives in the middle.

This is where the gut–bone axis becomes important. The microbiome influences inflammation, immune signaling, and ultimately bone turnover. Targeting that pathway offers another layer of protection.

One approach is Bondia by .bioscience—a symbiotic formula designed to support the microbiome with specific probiotics that work together to generate anti-inflammatory compounds. In clinical research, women near menopause taking Bondia showed dramatically reduced hip bone loss compared with placebo.

Why 65 is too late to begin monitoring bone health. Start early!

Bone health works a lot like retirement planning. In youth, you’re earning. Puberty through your twenties are the deposit years, when the skeleton builds and stores strength. By about 30, most people reach peak bone mass. The account is funded. From that point forward, the strategy shifts.

Now it’s about preservation. Because once those years pass, building significant new bone becomes difficult. The goal is protecting what you’ve already earned.

That’s why bone health can’t start at 65. The conversation should begin decades earlier. Screen sooner. Measure bone density around menopause—often near 50, sometimes earlier. Waiting until osteoporosis appears is like checking your bank account after retirement.

How can the gut microbiome affect menopause bone loss?!?

The gut microbiome is a vast ecosystem—trillions of microorganisms, mostly bacteria, living inside the digestive tract. They interact with food, communicate with the immune system, and influence metabolism across the body. What happens in the gut doesn’t stay in the gut. It shapes physiology far beyond digestion.

Bone is one of those systems. It may seem unrelated. The gut and skeleton never physically meet. But biology doesn’t require proximity to create influence.

Research in animal models revealed something remarkable. When menopause is induced in mice, bone loss normally follows. But in germ-free mice—animals raised without a microbiome—that bone loss largely disappears. The microbiome helps drive the bone response to declining estrogen.

My latest talk:
Why you wake up at 3AM in menopause (and how to fall back asleep)
https://youtu.be/StFd92nZ16Q

In this talk, I explain why so many women wake up in the middle of the night, often around 2–3AM, and have trouble falling back asleep.

Hormonal changes in perimenopause and menopause play a major role. Declining estradiol affects serotonin and melatonin production, which disrupts normal sleep cycles. At the same time, cortisol can rise during the night, making it harder to fall back asleep. Night sweats and hot flashes are also a common cause, but they are not the only reason.

I review other key contributors, including light exposure, circadian rhythm disruption, exercise timing, alcohol, late meals, medications, sleep apnea, and environmental factors like noise and temperature. I also share practical strategies to improve sleep, including light exposure, sleep hygiene, cognitive behavioral techniques, and when to consider hormone therapy or a sleep study.

Waking up occasionally is normal. Not being able to fall back asleep is not—and it is something that can be improved.

Sleep challenges in menopause are extremely common. Depending on what study you look at, 40%-60% of women in menopause struggle to sleep well. And waking up early is the most common sleep challenge that women report.

Frustratingly, there is also a very few tried and true therapies that women can depend on to fix their sleep and feel better.

We all know that if you don’t sleep well, you don’t feel good. So what can you do if you are one of the millions of women who consistently find themselves inexplicably awake at 3AM?

Join me today when I discuss the best approaches to limiting these awakenings and falling back to sleep when they do happen

Tonight, let’s talk about fatigue in menopause. Usually, when people talk about fatigue, it’s in the context of sleep, which is obviously very important. And sleep definitely suffers for many women throughout the menopause transition. But menopause fatigue is more than lack of sleep.

Loss of estradiol affects metabolism on a cellular level. Metabolism is the creation, utilization, and storage of energy, and it is foundationally tied to the health of mitochondria.

So let’s dig into what happens to energy when estradiol drops. And then we’ll explore ways to support your mitochondria so you can restore your energy levels and get back to doing what you love.
