What is perimenopause?
Perimenopause is the natural transition leading up to menopause. During this time, hormone levels begin to fluctuate and the body gradually moves toward the end of the reproductive years.
For many women, perimenopause begins in the late 30s to early 40s, although symptoms often become more noticeable in the mid-40s. This phase can last several years before menopause occurs.
While perimenopause is a normal life stage, the hormonal shifts involved can create a range of physical and emotional symptoms.
Understanding what is happening in the body can help women navigate this transition with greater clarity and support.
What happens to hormones during perimenopause?
Throughout the reproductive years, hormones such as oestrogen and progesterone follow a predictable monthly rhythm.
During perimenopause, this rhythm begins to change.
Ovulation may become less regular, which can lead to fluctuations in progesterone levels. Oestrogen levels may also rise and fall unpredictably throughout the cycle.
These hormonal changes can influence many systems in the body, including mood, metabolism, sleep and digestion.
Because hormones interact with the nervous system, gut microbiome and immune system, symptoms may appear in multiple areas of health.
Common symptoms of perimenopause
Every woman experiences perimenopause differently. Some women notice only subtle changes, while others experience more significant symptoms.
Common symptoms may include:
• irregular menstrual cycles
• heavier or lighter periods
• hot flushes or night sweats
• sleep disturbances
• mood changes or increased anxiety
• brain fog or difficulty concentrating
• fatigue
• weight changes, particularly around the abdomen
• increased bloating or digestive changes
These symptoms often fluctuate from month to month as hormone levels change.
Why symptoms occur
Many perimenopause symptoms are linked to the decline in progesterone that occurs when ovulation becomes less consistent.
Progesterone plays an important role in calming the nervous system and balancing the effects of oestrogen. When progesterone levels drop, women may notice increased anxiety, sleep disruption or mood changes.
At the same time, fluctuating oestrogen levels can influence body temperature regulation, metabolism and brain chemistry.
These shifts are a natural part of the transition toward menopause.
How long does perimenopause last?
Perimenopause can last anywhere from four to ten years, although the length of this phase varies widely between individuals.
Menopause itself is defined as 12 consecutive months without a menstrual period.
Once menopause occurs, the body transitions into the post-menopausal stage where hormone levels stabilise at lower levels.
A naturopathic approach to perimenopause
Although perimenopause is a natural life stage, many women benefit from additional support to help the body adapt to hormonal changes.
A naturopathic approach focuses on supporting the systems involved in hormone balance, including the endocrine system, nervous system and digestive system.
Support may include:
• regulating blood sugar and metabolism
• supporting the nervous system and stress resilience
• improving sleep quality
• supporting gut health and microbiome balance
• reducing inflammation
• supporting liver detoxification pathways involved in hormone metabolism
Lifestyle medicine, nutrition and herbal medicine can all play an important role in supporting women through this transition.

Herbs that may support perimenopause
In naturopathic practice, certain herbs are traditionally used to support hormonal balance and reduce common symptoms of perimenopause.
Depending on the individual presentation, herbs such as sage, black cohosh, vitex, lemon balm and ashwagandha may be used to support temperature regulation, mood, sleep and hormonal balance.
Herbal prescriptions are typically personalised to address each woman’s unique hormonal landscape.

When to seek support
If symptoms such as hot flushes, sleep disturbance, fatigue or mood changes are affecting daily life, additional support may be helpful.
Understanding the underlying drivers of symptoms - including hormonal fluctuations, stress, digestive health and lifestyle factors - can help guide more effective long-term strategies.
Personalised support
Perimenopause is a significant transition in a woman’s life, but with the right support it can also be an opportunity to strengthen long-term health.
If you are experiencing symptoms associated with perimenopause, a personalised naturopathic consultation can help identify the underlying drivers and create a supportive plan tailored to your body.
