Perimenopause: Understanding the Changes Your Body May Go Through
Perimenopause is a natural stage of life — but the changes that come with it can sometimes feel confusing. Here's what's really going on, and how to support yourself through it.
Your periods may suddenly become irregular. You may notice changes in your sleep, mood, energy levels, or even how your body feels day to day. You might wonder, "Is this normal?" or "Could I be going through perimenopause?"
Understanding what is happening can help you feel more prepared and more connected to your body.
What Is Perimenopause?
Perimenopause is the transition period before menopause.
During this stage, the ovaries gradually change how they function, and hormone levels — particularly estrogen — can fluctuate. These hormonal changes can affect your menstrual cycle, ovulation, and other aspects of your wellbeing.
Perimenopause doesn't happen in exactly the same way for everyone. Some women experience noticeable changes, while others may have relatively mild symptoms.
It is also important to understand that perimenopause is not the same as menopause. Menopause is reached when you have gone 12 consecutive months without a menstrual period, when there is no other explanation for the absence of periods.
When Does Perimenopause Start?
Perimenopause commonly occurs during the 40s, although the timing can vary from person to person.
For some women, the first noticeable sign may simply be a change in their menstrual cycle. This is why paying attention to your usual cycle can be useful — changes that seem small at first may become more noticeable over time.
How Can Your Period Change?
One of the most noticeable changes during perimenopause can be your menstrual cycle. Your periods may become:
- Earlier or later than usual
- Longer or shorter
- Heavier or lighter
- Less predictable
- Occasionally skipped
You may also notice that the number of days between periods changes from one cycle to another. These changes happen because ovulation can become less regular and less predictable as the body moves toward menopause.
However, an irregular period does not automatically mean you are experiencing perimenopause — other factors and health conditions can also affect menstrual cycles.
What Other Changes Might You Notice?
Perimenopause isn't only about your period. Hormonal fluctuations can be associated with a range of changes:
🔥 Hot flushes & night sweats
Sudden feelings of heat, sweating or discomfort, particularly at night.
🌙 Changes in sleep
You may find it harder to fall asleep, stay asleep or feel rested in the morning.
💭 Mood changes
Hormonal fluctuations, sleep changes and other factors can affect mood, irritability or emotional wellbeing.
🧠 Brain fog
Some women describe difficulty concentrating, forgetfulness or feeling mentally less sharp.
💧 Vaginal dryness
Changes in estrogen levels can affect vaginal tissues, leading to dryness or discomfort.
💗 Changes in sex drive
Hormones, sleep, stress and physical wellbeing can all influence sexual desire.
Not everyone experiences these symptoms, and their intensity can vary significantly from person to person.
PCOS vs Perimenopause: Are They the Same?
PCOS and perimenopause can sometimes appear similar because both can involve irregular periods and changes in ovulation. But they are not the same thing.
PCOS
Polycystic ovary syndrome (PCOS) is a hormonal and metabolic condition that can affect people during their reproductive years. It can be associated with irregular ovulation, irregular periods, excess androgen activity and other metabolic features.
Perimenopause
Perimenopause is a natural stage of reproductive ageing that occurs as the body transitions toward menopause. During this stage, ovulation can become irregular and menstrual cycles increasingly unpredictable.
The key difference:
PCOS is a health condition. Perimenopause is a natural life stage.
Because their symptoms can overlap, it's important not to assume that irregular periods automatically mean PCOS or perimenopause.
Can You Still Ovulate During Perimenopause?
Yes. During perimenopause, ovulation may become less frequent or unpredictable, but it can still occur. This means pregnancy is still possible during perimenopause.
As the transition progresses, ovulation eventually stops and menstruation ends, leading to menopause.
How Can You Support Your Body During Perimenopause?
There isn't one supplement, food or lifestyle change that can stop perimenopause. Instead, think about supporting your overall health and nutritional needs as your body goes through this transition.
Focus on a balanced diet
A varied diet can help provide the nutrients your body needs — a good balance of vegetables, fruits, whole grains, protein sources and healthy fats.
Support bone health
Estrogen levels decline as women approach menopause, making bone health particularly important. Adequate calcium and vitamin D intake, together with appropriate physical activity, can support healthy bones.
Stay physically active
Regular movement supports muscle strength, bone health, cardiovascular health and overall wellbeing — walking, strength training, yoga or any activity you enjoy.
Prioritise sleep
A consistent sleep routine, a comfortable bedroom and managing stress may help support better sleep.
Pay attention to your body
Keeping track of your menstrual cycle and noting changes in symptoms can help you understand your individual patterns. If something feels unusual or concerning, don't simply assume it's part of perimenopause.
When Should You Speak to a Healthcare Professional?
Many changes during perimenopause are normal, but unusual or very heavy bleeding should not automatically be dismissed as perimenopause.
Speak with a healthcare professional if you experience bleeding that is unusually heavy, prolonged, occurs between periods, or happens after menopause. A healthcare professional can help determine whether your symptoms are related to perimenopause or whether another condition needs to be considered.
Know Your Body. Understand the Changes.
Perimenopause is a transition — and every woman's experience can be different. Your periods may change. Your sleep or mood may change. Your body may feel different from how it did a few years ago. These changes don't necessarily mean something is wrong.
Pay attention to the changes.
Support your nutritional needs.
Make informed choices for your wellbeing.
Most importantly, give yourself the time and space to understand what your body is telling you. 💗
