Menopause May Be More Than a Transition: Understanding the “Physiological Cliff”

We’ve been talking about menopause as a transition for years.

But what if, biologically, it’s more of a tipping point?

A fascinating new preprint analyzed an extraordinary amount of data: 300 million laboratory test results from approximately 1.3 million women across two large national cohorts, to look at what happens to the body in relation to the final menstrual period.

The researchers found something striking: rather than seeing menopause as a smooth, gradual shift, they identified what they describe as a “physiological cliff.” Around the final menstrual period, they observed relatively abrupt changes across multiple biological systems, including endocrine, skeletal, liver, kidney, inflammatory, and lipid-related markers. Perhaps even more interesting is that signs of physiological dysregulation appeared more than a decade before the final menstrual period.

For many women, the menopausal experience begins long before their periods stop. Sleep can change. Mood can shift. Anxiety can increase. Executive functioning can feel different. Energy and motivation can fluctuate. Physical symptoms may emerge. And yet women are often told they’re “not there yet” because they’re still menstruating.

This reinforces the importance of taking symptoms seriously well before menopause is technically reached.

A woman doesn’t need to be postmenopausal for hormonal changes to affect how she feels, thinks, sleeps, functions, and copes.

This is particularly relevant for women with ADHD, who may already be navigating challenges with attention, emotional regulation, executive functioning, and energy. When hormonal changes are layered on top of that, the strategies that worked for years may suddenly feel less effective.

Therapy can help women make more sense of these changes. It can involve identifying patterns, adapting expectations, developing strategies that match changing capacity, and addressing the grief that can come with realizing that a previous way of functioning isn’t sustainable anymore.

The study also found that hormone replacement therapy appeared to attenuate some of the physiological changes observed around menopause. That’s an important finding, but it shouldn’t be interpreted as evidence that HRT is appropriate for everyone. Medical treatment decisions need to be individualized and discussed with an appropriately qualified healthcare provider.

And because this is a preprint, these findings need to be replicated and critically evaluated through further research.

Still, the larger message is compelling: Menopause isn’t simply the moment periods stop. The transition may begin much earlier, involve far more of the body than we’ve traditionally recognized, and represent a significant window for prevention and support.
