Do you ever find yourself Googling things like, “Is this stress or hormones?” or “Why do I feel like a stranger in my own body?” — Well, so have we. Many people start asking these questions long before anyone ever mentions the word perimenopause.
What makes this especially confusing is that the symptoms of perimenopause and hormonal imbalances overlap almost entirely. Mood shifts, fatigue, disrupted sleep, weight changes, and irregular cycles can show up in both scenarios, often leaving people unsure of where to begin. Let’s slow this down and walk through what’s actually happening.
—————————————————————————————————————
What Perimenopause Is (and What It Isn’t)
Perimenopause is the transitional phase leading up to menopause (1), marked by increasing variability in ovarian hormone production. Instead of a smooth hormonal decline, estrogen and progesterone behave more like a rollercoaster — sometimes surging, sometimes dipping, and often doing both within the same cycle.
This transition can begin years before menopause, sometimes in the mid-to-late 30s, and may last anywhere from four to ten years. Progesterone tends to decline first as ovulation becomes less consistent, while estrogen fluctuations are largely responsible for many of the cognitive and emotional symptoms people notice early on, leaving women+ particularly vulnerable to depression (2). Understanding that perimenopause is driven by variability, not simply low hormone levels, helps explain why symptoms can feel unpredictable from month to month.

What We Mean by “Hormonal Imbalance”
Unlike perimenopause, “hormonal imbalance” isn’t tied to a specific life stage. It’s a broad term used to describe situations where hormone signaling becomes disrupted due to internal or external stressors, even when hormone levels appear normal on lab work.
These disruptions often involve stress hormones, blood sugar regulation, thyroid signaling, gut health, or inflammation. For example, those who experience chronic stress are more likely to release stress hormones — cortisol and catecholamines (adrenaline and noradrenaline) — more frequently into the bloodstream, which can cause a hormone imbalance. This can lead to irregular menstruation, low energy, insomnia, and infertility (3). Starting to see the connections?
Because hormones rely on proper communication between organs and tissues, anything that interferes with that communication — tumor, disease, nutrition, chronic stress, lack of sleep, digestive issues (4) — can create symptoms that feel hormonal in nature. And if you’re in the age range for perimenopause, it’s no wonder you’re questioning if you’re slowly entering menopause.

Why the Symptoms Feel So Similar
Hormones don’t operate in isolation; they act through interconnected systems involving the:
brain
gut
liver
nervous system.
When any of these systems become stressed or dysregulated, hormone signaling downstream can feel chaotic — regardless of the original trigger.
In perimenopause, fluctuating estrogen and progesterone alter how the brain responds to neurotransmitters involved in mood, sleep, and stress regulation. In hormonal imbalances, similar symptoms arise because cortisol, insulin, or gut-mediated estrogen metabolism interfere with those same pathways. This overlap explains why supporting blood sugar stability and gut health — themes explored in more detail in our Protein for Hormonal Health (5) and The Fiber-Hormone Connection (6) blogs — often improves symptoms across both scenarios.

Perimenopause vs. Hormonal Imbalance: A Symptom Comparison
At this point, it helps to zoom out and compare patterns side by side. While no chart can capture every individual experience, looking at common trends can offer helpful context — especially when symptoms feel overwhelming or contradictory.
This comparison isn’t meant to label or diagnose; it’s simply a way to organize information and notice which patterns resonate most strongly with your experience.
—————————————————————————————————————
Can You Have Both at the Same Time?
Yes — and this is more common than most people realize. Entering perimenopause doesn’t automatically resolve existing stress, metabolic challenges, or inflammatory conditions that were already affecting hormone signaling. In fact, fluctuating estrogen and progesterone during perimenopause can magnify pre-existing imbalances, making symptoms feel more intense, persistent, and harder to predict.
Chronic stress is a big player here. Elevated cortisol can interfere with sleep, blood sugar regulation, and thyroid signaling — all of which overlap with symptoms of perimenopause (7). This creates a layered experience, not just a single hormone “acting up,” but rather multiple systems talking over each other at the same time.
Conditions like polycystic ovary syndrome (PCOS), thyroid dysfunctions, or inflammatory disorders such as endometriosis can further complicate this picture, especially in individuals who were already hormone sensitive before perimenopause began. That overlap — and why inflammation matters so much — is explored more deeply in the Endometriosis 101 blog (8).

So… How Do You Tell Which One You’re Dealing With?
Instead of focusing on finding the correct diagnosis on your own, it’s more helpful to look for patterns over time. And if necessary, visit your primary care provider (PCP) or gynecologist (OB-GYN), or schedule a call with us. Asking yourself when symptoms show up, and what seems to influence them, can provide far more clarity than a single hormone panel.
Here’s a simplified way to think about it:
Hormonal imbalance symptoms tend to feel reactive, flaring with stress, missed meals, poor sleep, or digestive disruption — and often improve when those factors are addressed.
Perimenopausal symptoms, on the other hand, often feel unfamiliar and less predictable, even when routines, diet, and stress levels stay consistent.
Overlapping symptoms (fatigue, brain fog, anxiety) can blur the line, especially when thyroid dysfunction is present. Both situations benefit from foundational support, but recognizing the dominant driver can guide where to place your energy first.

The Big Picture
Perimenopause isn’t a sudden breakdown, and hormonal imbalances aren’t personal failures. They’re both reflections of how adaptable — and sensitive — the endocrine system truly is. Rather than signaling “something is wrong,” symptoms are often your body’s way of communicating that multiple interconnected systems are shifting and need support.
Understanding whether your hormones are fluctuating due to reproductive transition, struggling to communicate due to stress or metabolic strain, or a combination of both allows for more compassionate and effective support. Research suggests that combining nutritional, physical, and stress-management approaches can help mitigate many common symptoms and support overall health during perimenopause and hormonal imbalance itself.
Nutrition & Diet (9): Eating balanced meals rich in whole foods, lean protein, healthy fats, and complex carbohydrates supports stable blood sugar — a foundational element of hormone balance. Additionally, diets high in fiber and omega-3 fatty acids have been associated with better mood regulation, anti-inflammatory effects, and metabolic support.
Exercise & Movement (9): Regular physical activity, such as aerobic exercises and strength training, has been linked to improved mood, reduced vasomotor (constriction and dilation of blood vessels), better sleep, and maintenance of muscle and bone health during the perimenopausal transition.
Stress Management (10): Chronic stress elevates cortisol, which can interfere with reproductive hormones and worsen mood, sleep, and metabolic symptoms. Mind-body practices such as mindfulness meditation, deep breathing exercises, and yoga have been shown to reduce stress and support hormonal resilience.
Integrating these evidence-based strategies can help you feel more in control — not by “fixing” a problem with a magic wand, but by strengthening the systems that actually influence hormone signaling and overall well-being.
Your hormones aren’t turning against you — they’re communicating. Learning how to listen and support the whole system is where real clarity begins.
