Menopause Symptoms: Recognising the Signs of Hormonal Change
Menopause Symptoms: Recognising the Signs of Hormonal Change
Menopause is not a switch that suddenly flicks overnight. For most women it is a gradual hormonal transition that unfolds over several years.
Long before periods stop completely, the body begins adjusting to changing hormone patterns. Oestrogen and progesterone production becomes less predictable, which is why symptoms may appear in waves rather than in a clear sequence.
As a chiropractor who has spent more than two decades observing how the body adapts to change, one of the most important messages I share with women is this: your body is not failing. It is recalibrating.
Understanding the signs of menopause can help remove uncertainty and allow you to approach this stage of life with greater clarity and confidence.
Quick Guide: Common Signs of Menopause
Menopause symptoms can affect many different systems in the body. Some of the most commonly recognised changes include:
- Hot flushes and night sweats
- Sleep disruption
- Mood changes or increased anxiety
- Irregular menstrual cycles
- Fatigue and reduced energy
- Brain fog or difficulty concentrating
- Joint stiffness or discomfort
- Digestive changes
- Weight redistribution
- Skin or hair changes
What Is Menopause?
Menopause is defined as the point in time when a woman has gone twelve consecutive months without a menstrual period.
The transition leading up to this moment is called perimenopause, and it is during this stage that many of the first hormonal changes occur.
During the reproductive years, the ovaries produce most of the body’s oestrogen and progesterone. As menopause approaches, ovarian hormone production gradually declines.
Because these hormones influence many systems throughout the body, their fluctuation can affect sleep, mood, metabolism, joints, skin and cognitive function.
Why Many Women Feel “Not Quite Themselves”
“One of the most common things women say during this transition is that they simply don’t feel like themselves anymore.”
Energy levels may feel different. Sleep can become less predictable. Concentration may fluctuate. Emotions that once felt steady can sometimes feel more sensitive or reactive.
These changes can be confusing, especially when they appear gradually and without a clear explanation.
For many women, the most reassuring realisation is that these experiences are not unusual. They often reflect the body adjusting to shifting hormone patterns rather than something being “wrong”.
Understanding what is happening physiologically can help transform uncertainty into clarity, allowing women to approach this stage of life with greater confidence and self-compassion.
Early Signs of Menopause
Many women begin noticing subtle changes years before their final menstrual cycle.
Many of the earliest changes women notice during this stage are often referred to as perimenopause symptoms, reflecting the hormonal fluctuations that occur before menopause itself.
Some of the earliest signs can include:
- changes in cycle length
- heavier or lighter periods
- disrupted sleep
- mood fluctuations
- new sensitivity to stress
- increased fatigue
This transition phase typically begins in the mid-40s, although the timing can vary from woman to woman.
Many women also begin noticing changes in how their body regulates temperature, particularly episodes of sudden warmth known as hot flushes or night sweats. Understanding why these occur can help make sense of one of the most commonly recognised menopause symptoms.
Many women also notice changes in sleep patterns during menopause ( sleep and menopause → link to your future sleep article), which may be influenced by shifting hormone levels.
Hot Flushes and Night Sweats: Understanding What Is Happening
Hot flushes and night sweats are among the most commonly recognised symptoms of the menopause transition. Many women describe a sudden wave of heat rising through the chest, neck or face, sometimes accompanied by flushing of the skin, perspiration and a rapid heartbeat.
These experiences are closely linked to changes in how the brain regulates body temperature.
A small region of the brain called the hypothalamus acts as the body’s thermostat. It constantly monitors internal temperature and helps maintain balance by triggering responses such as sweating when the body becomes too warm.
Oestrogen plays a role in how the hypothalamus regulates temperature. As hormone levels begin fluctuating during perimenopause, the temperature control system can become more sensitive. Even small changes in internal temperature may trigger the hypothalamus to activate cooling responses such as sweating and flushing.
This is why a hot flush can sometimes feel as though it appears suddenly and without warning.
Many women also notice that emotional stress can coincide with episodes of flushing. The hypothalamus is involved not only in temperature regulation but also in the body’s stress response system, which works closely with the adrenal glands and the release of stress hormones such as adrenaline and cortisol.
Because these systems are interconnected, moments of emotional or mental stress may sometimes coincide with changes in temperature regulation. It’s not unusual for women to notice a hot flush appear after a stressful phone call, a moment of pressure or an emotionally charged situation.
Night sweats are simply the same process occurring during sleep. Many women find themselves repeatedly adjusting the bedding during the night, kicking the doona off when the heat wave arrives, then pulling it back on again once the body cools down, which I endearingly refer to as the “doona dance.”
Understanding what is happening physiologically can help make these experiences feel less mysterious and more like part of the body adapting to shifting hormone patterns during the menopause transition.
Your body is not broken. It is adjusting to changing hormonal signals and gradually finding a new balance.
Why Menopause Can Affect the Whole Body
One reason menopause symptoms can appear in so many different ways is that oestrogen receptors are present throughout the body, not just within the reproductive system.
These receptors are found in many tissues including the brain, skin, bones, joints, blood vessels, muscles and parts of the digestive system.
Throughout the reproductive years, oestrogen interacts with these receptors and contributes to the regulation of many physiological processes such as temperature control, bone maintenance, skin health, mood regulation and metabolic activity.
As hormone patterns begin shifting during perimenopause and menopause, these systems may respond in different ways. This is why the menopause transition can involve changes that affect multiple areas of the body rather than a single isolated symptom.
Understanding the widespread influence of oestrogen helps explain why menopause is often experienced as a whole-body transition rather than purely a reproductive one.
Why Menopause Symptoms Occur
Hormonal shifts during menopause influence several key systems in the body.
Ovarian Hormone Changes
The ovaries gradually reduce their production of oestrogen and progesterone as menopause approaches. Instead of following predictable monthly patterns, hormone levels may begin fluctuating from one cycle to the next.
You could think of the ovaries as slowly preparing for retirement after decades of consistent work. Rather than switching off overnight, their activity gradually winds down, which is why the transition into menopause often unfolds over several years.
Adrenal Compensation
As ovarian hormone production begins to decline, the body may rely more heavily on the adrenal glands to contribute to hormone balance.
The adrenal glands are best known for producing the stress hormones adrenaline and cortisol, which help the body respond to physical and emotional stress. They also produce small amounts of precursor hormones that can be converted into other hormones within the body.
Because the adrenal glands play such an important role in both stress response and hormone pathways, periods of prolonged stress can sometimes make the menopause transition feel more challenging for some women.
Adipose Tissue and Hormones
Fat tissue can produce small amounts of oestrogen through a process called aromatisation, where certain hormones are converted into oestrogen within the body.
As ovarian hormone production declines during menopause, adipose tissue can become one of the body’s secondary sources of oestrogen. While the amount produced is much smaller than what the ovaries once supplied, it may still contribute to overall hormone activity.
During midlife, many women notice that body fat distribution begins to shift. Instead of being stored more around the hips and thighs, fat may increasingly accumulate around the abdomen and waistline. This pattern is sometimes referred to as a central or abdominal distribution.
Several factors may influence this change, including hormonal shifts, metabolic changes, stress patterns and lifestyle factors. Because adipose tissue plays a role in hormone metabolism, the body’s fat distribution can interact with broader hormonal changes occurring during the menopause transition.
Liver Hormone Processing
The liver plays an important role in metabolising and clearing hormones from circulation. After hormones such as oestrogen have been used by the body, the liver helps convert them into forms that can be safely eliminated.
This process involves several stages of biochemical activity, sometimes referred to as detoxification pathways, where hormones are broken down and prepared for removal through bile and the digestive system.
Because the liver helps regulate how hormones are processed and cleared, its overall function can influence the balance between hormone production and hormone elimination.
A number of factors may influence how efficiently these pathways operate, including nutritional status, digestive health, exposure to environmental toxins and overall metabolic wellbeing.
During the menopause transition, when hormone patterns are already shifting, supporting healthy liver function can be one of the ways the body maintains balance within its broader hormonal system.
Because these systems interact, menopause symptoms often reflect whole-body adaptation rather than a single isolated change.
Menopause symptoms reflect the interaction between several systems including the ovaries, adrenal glands, adipose tissue and liver.
Stages of the Menopause Transition
Women generally move through three recognised stages.
Perimenopause
The transition phase when hormones fluctuate and cycles become less predictable.
Menopause
Defined as twelve months after the final menstrual period.
Post-menopause
The years following menopause when hormone levels stabilise at lower levels.
Understanding these stages can help explain why symptoms may change over time.
Common Symptoms During Menopause
While every woman’s experience is unique, several symptoms are commonly reported during menopause transition.
Hot flushes and night sweats are among the most widely recognised, but other changes may also occur as hormone patterns fluctuate.
Some women notice changes in sleep quality during menopause transition (link to sleep and menopause page), finding it harder to fall asleep or stay asleep through the night. Others describe periods of mental fatigue or difficulty concentrating, sometimes referred to as “brain fog.”
Mood changes may also appear for some women, including increased emotional sensitivity or feeling more easily overwhelmed during times of stress.
Changes in joint comfort (link to arthritis condition page), skin texture, hair thickness or body fat distribution are also sometimes noticed during this stage of life.
Not every woman experiences all of these changes, and the intensity can vary significantly from person to person. For many women, symptoms gradually settle as the body adapts to its new hormonal environment.
How Long Does Menopause Last?
The menopause transition varies between individuals.
Perimenopause may last several years, during which symptoms can appear intermittently. After menopause occurs, the body continues adapting to its new hormonal baseline.
For many women, symptoms gradually become less disruptive as the body finds a new equilibrium.
Why Symptoms Differ Between Women
Menopause can feel very different from one person to another.
Several factors may influence symptom intensity:
- stress levels and adrenal health
- sleep patterns
- metabolic health
- gut and liver function
- inflammatory load
- lifestyle factors
These variables help explain why some women experience only mild symptoms while others may notice more significant changes.
Supporting Your Body Through the Menopause Transition
Many women choose to explore supportive lifestyle strategies during the menopause transition as part of their broader wellbeing routine.
Areas that are often discussed include:
- maintaining consistent sleep routines
- prioritising balanced nutrition
- supporting digestive health
- managing stress levels
- maintaining regular physical activity
These approaches can help support overall balance as the body adapts to changing hormone patterns.
Some women also choose to incorporate topical botanical preparations or nutritional formulations into their daily routine as part of their personal approach to midlife wellbeing.
Within the Dr Kez Chirolab range, products such as Hormotion® Lotion Natural Wild Yam Cream, formulated with plant-derived ingredients including wild yam and supportive botanicals, and PlantEm® Essentials CleanEm Detox, designed to support digestive and liver pathways, are examples of products some women choose to include in their routine.
Because every woman’s experience of menopause is unique, what feels supportive can vary from person to person.
Some women also explore topical or nutritional options as part of their broader menopause support routine.

Frequently Asked Questions About Menopause
What are the symptoms of menopause?
Menopause symptoms can vary widely between individuals but commonly include hot flushes, night sweats, sleep disruption, mood changes, fatigue, brain fog, joint discomfort and changes in menstrual cycles. These symptoms occur as hormone patterns shift during the menopause transition.
What are the first signs of menopause?
The earliest signs of menopause often begin during the transitional stage known as perimenopause. During this time, hormone levels begin fluctuating rather than following the regular patterns of the reproductive years.
Common early changes may include irregular menstrual cycles, sleep disruption, mood fluctuations, increased fatigue and occasional hot flushes. Not every woman experiences the same symptoms, and the timing of these changes can vary.
What age does menopause usually begin?
Most women experience menopause between the ages of 45 and 55, although the timing varies between individuals. The transition leading up to menopause, called perimenopause, can begin several years earlier.
Genetics, overall health, lifestyle factors and environmental influences may all play a role in when menopause occurs.
What is perimenopause?
Perimenopause is the transitional phase leading up to menopause. During this stage the ovaries gradually begin producing less oestrogen and progesterone, and hormone levels may fluctuate from month to month.
These fluctuations can influence menstrual cycles, sleep patterns, mood and energy levels. Perimenopause can last several years before menopause is reached.
How long does menopause last?
Menopause itself refers to the point when a woman has gone twelve consecutive months without a menstrual period.
However, the broader transition often spans several years. The phase before menopause is known as perimenopause, and the years following menopause are called post-menopause.
Each woman’s experience of this transition is unique.
Why do menopause symptoms happen?
Menopause symptoms are primarily related to changes in hormone patterns, particularly the decline and fluctuation of oestrogen and progesterone.
These hormones interact with many systems in the body, including the brain, nervous system, metabolism, joints, skin and digestive system. As hormone levels shift, the body adapts to a new hormonal environment, which can lead to a range of physical and emotional changes.
Can menopause affect sleep?
Many women report changes in sleep during the menopause transition. Hormonal fluctuations can influence the body’s temperature regulation, stress response and circadian rhythm.
Hot flushes, night sweats and changes in nervous system regulation may also contribute to disrupted sleep patterns.
Can menopause affect mood or mental clarity?
Hormonal changes during menopause may influence brain chemistry and nervous system regulation. Some women notice changes in mood, increased sensitivity to stress or periods of mental fatigue.
Many women also describe episodes of “brain fog,” which may involve difficulty concentrating or temporary lapses in memory.
When should I seek professional advice about menopause symptoms?
If symptoms become persistent, disruptive or concerning, discussing them with a qualified healthcare professional may be helpful.
An individualised assessment allows health history, lifestyle factors and current concerns to be considered when developing a tailored plan.
