Bone Loss You Can't Feel, and When to Ask for screening

Bone mineral density loss doesn't announce itself. There's no specific symptom or tell tale ache that shows up early, no marker on a standard blood panel (a serum calcium level doesn't tell us if you have enough in your diet to support your bone health), nothing you'd notice on an ordinary weekday that tells you your skeleton is quietly losing its structural scaffolding. The steepest drop in bone density happens in the 3 year window spanning your final menstrual period, which for a lot of readers lands right in the decade you're probably in now (40s or 50s). Bone loss begins to accelerate in the 1-2 years before your last period, declines at the fastest rate in the 1-2 years immediately following your last period, then slows down but continues at around 2 years after menopause. Canadian screening guidelines don't advise screening with the gold standard DEXA scan test until age 70 (or 65 if you have one risk factor, or over 50 with certain very specific conditions I'll outline below). These recommendations are not because the guideline is outrageously negligent (although to be honest, sometimes it can feel that way), it's actually built to evaluate people who've already accumulated the risk rather than look during the years when the most risk accumulation is in the middle of happening.

The pattern I keep seeing in practice

The patient in my office who really wants to prioritize and be proactive about their bone health usually appears with a very clear motivator: watching their mother go through osteoporosis treatment or a hip fracture, a parent's fracture recovery that they never fully bounced back from, even years later, sometimes a medication that was supposed to help and didn't do quite what everyone had hoped.

I don't want this to be scary for you. The first-line medications for osteoporosis are first-line for good reason, they're well studied, and I'd genuinely rather my patients benefit from them than avoid treatment out of fear. But biology doesn't come with guarantees attached, even with the right treatment for the right person, and watching that up close, as a daughter, changes how a woman thinks about her own bones decades before anyone hands her a requisition. If some version of that is part of why you're reading this, you're paying attention to something real.

An Important Distinction

Bone mineral density (BMD), bone health, osteoporosis, osteopenia, low bone mass, these are all things we talk about and focus on, but the real issue we all truly care about is fracture risk. All of those other terms help us measure someone's fracture risk and while they are very important it's essential to remember that it is only one piece of the equation and that a declining BMD score is not a doomsday sentence to an inevitable fracture, just like BMD preservation is not a guarantee that you won't break a bone if you take unnecessary risks with your body. Your BMD by itself doesn't mandate your quality of life or functional independence, however a fracture in your 80s most certainly can. I just want to call it out plainly because in some cases there can be a tendency to over-fixate or get distracted by certain metrics that we end up missing the bigger more important picture, and BMD risks falls into that category.

What the screening guidelines actually say

With that caveat above in mind, here's what the Canadian 2023 updated guidelines say about screening with a DEXA scan (dual x-ray absorptiometry), the current gold standard for screening.

When screening starts:

• Age 70+: everyone, risk factors or not

• Age 65+: if you have even one risk factor (see below)

• Age 50+: if you've had a fragility fracture, or you're carrying two or more risk factors

The risk factors are specific and listed here:

• A fracture from a minor fall after age 40 (ie. fragility fracture)

• A parent who has broken a hip

• Steroid medication use (at a specific dose, for a specific duration)

• Another condition that causes secondary bone loss (like hyperparathyroidism)

• Current smoking

• Heavy alcohol use

• A fall in the last year (with or without fracture)

• BMI under 20

One more thing worth knowing on its own: risk is highest in the two years right after any fracture, which is exactly the window a rushed visit can miss.

What is considered a fragility fracture?

A fragility fracture is when a fracture results from a force equivalent to a fall from standing height or less that would not typically break a healthy bone. They typically happen in the hip, vertebrae/spine, shoulder, forearm/wrist, and pelvis and notably do not include fractures of the hands/fingers, feet/toes, ankle, or skull and face.

Here's the rub in a publicly funded health care system

A provider agreeing that screening makes sense doesn't always mean it gets funded. In April 2026, Osteoporosis Canada publicly called out changes in OHIP (Ontario's publicly funded health insurance program) billing rules for subsequent bone density testing, arguing they don't actually line up with that 2023 national guideline. So if your request for a repeat scan gets met with hesitation, that's not necessarily your provider disagreeing with the evidence. Sometimes it's the public system's own billing rules that are out of step with the guideline, not the judgment behind your ask. Private-pay scans are available for people who want to move sooner than the funded rules currently allow. I don't agree with the situation, I just want you to understand something your doc might not have time to fully explain in your 7 minute visit about menopause.

What can help? Write your own list down before your next appointment. Does anyone in your family have this history? Have you had a fracture that seemed too minor to explain? Are you on a medication that might affect bone? That list is the real leverage point, years before a scan ever gets ordered, and it's worth having ready if the first answer you get is "not yet."

Yes, take your calcium. But also…

Yes, calcium and vitamin D are well established considerations, but a study out this year in Osteoporosis International looked at women who already had enough calcium in their diet and were already on bone medication (hormone therapy or an antiresorptive), and found the calcium supplement itself wasn't the heavy lifter (Papageorgiou et al., 2026). This aligns with the existing observational evidence that in people who get enough calcium from their diet, adding more calcium via supplements doesn't make a significant difference to BMD or fracture risk. Interestingly, in this recent study what actually influenced how well the medication worked in this population was protein intake. Before you roll your eyes at yet another plug for protein during menopause and beyond (believe me, I don't blame you!), let's understand who this specific research applies to: these were women with an osteoporosis diagnosis who were already meeting their dietary requirements for calcium and being actively treated with medication, so this isn't a green light to skip your calcium supplement, but it is a reason to caution against assuming the pill in your cabinet has you fully covered.

Another important conversation that is often overlooked

Hormone therapy is a recognized way to help protect bone density while you're on it. When someone stops, density is expected to drift back toward where it would have been without treatment, usually within a year or two. This is one of the reasons people choose to continue on hormone therapy well past menopause. Keep in mind this is not a reason to fear stopping it if you need to. It's a reason for the conversation about stopping to include what gets monitored next, and in my experience, that part often gets overlooked. If you're planning to come off hormone therapy, or you already have, ask what the follow-up plan for your bones actually looks like. It's a fair question that deserves a concrete plan.

Where this goes next

None of this is fatalism. Genetics carries real weight, your mother's history matters, but bone responds to load and impact. What you actually do about that, the how, is a bigger conversation. It's the one I'm walking through at The Perimenopause Summit this month (my session airs September 24), where I get into the specifics: whether the weighted vest makes a real difference, what vitamin K's real job is, why walking is just not enough, and what the specific exercise recommendations include. This piece is about knowing when screening can be helpful. The upcoming summit talk is about what to do once you have the answer.

For now, write your risk factors down before your next appointment. And for anyone who wants a second set of eyes on the whole picture, whenever you're ready, Book a Free Discovery Consult. I got you.
