Perimenopause Explained
Understanding the Transition Before Menopause
Perimenopause unfolds gradually and looks different from one woman to another. Symptoms can be inconsistent, overlap with other health patterns, or appear at an age where they are dismissed as stress, aging, or “just life.”
​
Without clear context, this can feel confusing or destabilizing. Many women come to see these changes as inevitable decline rather than as a physiological transition that can be understood and met with agency
This page exists to offer orientation and understanding.
What is Perimenopause
Perimenopause is the phase before menopause when reproductive hormones begin to fluctuate and decline. Menopause itself is defined as the point when you have gone twelve consecutive months without a menstrual period. Perimenopause refers to the years leading up to that point.
​
For some women, this phase begins in the early forties. For others, it starts earlier or later. There is no single timeline that applies to everyone.
​
What matters more than age is pattern.
​
Hormonal shifts during perimenopause are often uneven. Estrogen and progesterone do not decline smoothly. They fluctuate. This variability is what drives many of the changes women notice long before menopause is formally reached.
How Perimenopause Often Shows Up
Perimenopause is not only about hot flashes.
​
Many women first notice changes such as:
​
-
Shifts in energy or stamina
-
Disrupted sleep or changes in recovery
-
Mood changes, irritability, or increased anxiety
-
Difficulty focusing or feeling mentally sharp
-
Changes in appetite, weight distribution, or response to food
-
Changes in desire, intimacy, or emotional closeness
A growing sense that familiar routines no longer work.
​
These experiences are common, but they are not always explained clearly or connected back to hormonal change. Without that context, it is easy to assume something is wrong with you, rather than recognizing that your body is operating under new conditions.
Why Old Strategies Stop Working
During perimenopause, your body’s tolerance for stress often changes.
​
What once felt manageable may now feel depleting. Training harder, restricting food, pushing through fatigue, or ignoring recovery signals can backfire more quickly than before.
​
This does not mean you are simply getting old.
Your system is reconfiguring, shifting into a different way of functioning, with different thresholds, signals, and needs.
Many experiences during perimenopause are widely shared, even if they are not widely discussed. At the same time, common does not mean untouchable or something you must simply endure.
There are often multiple ways to work with these changes, depending on your body, your values, your capacity, and your life circumstances. Understanding comes first. Choice follows.​
Perimenopause Lives in Context
While hormonal changes are central, perimenopause often coincides with broader life shifts.
​
Many women find this phase overlaps with changes in identity, work, relationships, caregiving roles, or long-held assumptions about how life is supposed to look.
​
Because these changes are happening simultaneously, it can be difficult to separate what is physiological from what is emotional or situational. In reality, they are often interacting.
​
Understanding perimenopause means understanding both the body and the context in which it is living.
Nourishment During Perimenopause
Perimenopause often changes how your body responds to food.
You may notice energy crashes, stronger reactions to missed meals, digestive changes, or clearer links between what you eat and how you feel mentally or emotionally. What once felt flexible may now feel less forgiving.
​
Rather than restriction or control, nourishment during perimenopause works best when it supports regulation and resilience.
​
This means eating in a way that supports:
​
-
More consistent energy across the day
-
Fewer crashes and reactive states
-
Emotional steadiness and cognitive clarity
The goal is not a perfect diet.
It is nourishment that makes life more workable under changing physiological conditions.
Why Early Understanding Matters
When perimenopause is recognized early, it becomes something you can work with rather than something that surprises you later.
​
Language reduces confusion. Context reduces self-blame.
Understanding opens the door to more informed decisions about nourishment, movement, rest, relationships, and support.
