Perimenopause Symptoms: What Changes in Your Body and When

Perimenopause can feel confusing, especially when changes begin appearing unexpectedly. One month your period arrives earlier than usual, the next month you may notice disrupted sleep, mood changes, or feeling warmer than normal. If you're wondering whether these shifts are connected, you're not alone.

Perimenopause is a natural stage of life that occurs before menopause, and it can bring a range of physical and emotional changes as hormone levels begin to fluctuate. Understanding what is happening in your body can help you feel more informed, prepared, and confident during this transition.

What Is Perimenopause?

Perimenopause is the transition period leading up to menopause. During this time, the ovaries gradually begin producing lower and more variable levels of hormones, particularly oestrogen and progesterone^1,2. While menopause is officially reached when a person has gone 12 consecutive months without a menstrual period, perimenopause can begin several years beforehand. For many women, symptoms first appear during their forties, although some may notice changes earlier².

Women experience perimenopause differently. Some notice only mild changes, while others experience symptoms that have a significant impact on their daily routines.

When Do Perimenopause Symptoms Usually Start?

There is no exact age at which perimenopause begins. Symptoms may develop gradually, often years before menopause itself^1,2,3. In the early stages, menstrual changes are often the first noticeable sign. It's important to remember that symptoms may come and go. You may feel completely normal for several weeks or months before noticing further changes².

Common Early Symptoms of Perimenopause

Changes to Your Menstrual Cycle

One of the most common signs of perimenopause is a change in your usual menstrual pattern.

You may notice:

• Periods becoming shorter or longer
• Changes in flow, including heavier or lighter bleeding
• Longer gaps between periods
• Periods arriving earlier than expected
• Occasionally missing a period altogether

Because hormone levels fluctuate rather than decline steadily, cycle irregularity is often one of the first indicators that perimenopause has begun^1,2,3.

Hot Flushes and Night Sweats

Many women associate menopause with hot flushes, but these can begin during perimenopause^4,5. A hot flush is a sudden feeling of warmth that may spread across the face, neck, and chest. Some women also experience sweating, redness of the skin, or a rapid heartbeat. Night sweats are hot flushes that happen while sleeping and can sometimes interfere with rest.

Sleep Disturbances

Changes in sleep are another common symptom. Waking up more frequently during the night, struggling to fall asleep and feeling tired despite sleeping for a similar number of hours are all perimenopause associated. Sleep difficulties may be linked to hormonal fluctuations^2,4, night sweats, stress, or a combination of factors.

Emotional and Mental Changes

Perimenopause does not only affect the body. Hormonal fluctuations can also influence emotional wellbeing.

Some women report experiencing^2,3,4:

• Mood swings
• Increased irritability
• Feeling more emotional than usual
• Difficulty concentrating
• Brain fog or forgetfulness
• Increased anxiety

These experiences can feel frustrating, particularly if they seem to appear without an obvious cause. Understanding that these changes may be linked to perimenopause can help provide reassurance.

Physical Changes You May Notice

Vaginal Dryness and Intimate Discomfort

Lower oestrogen levels can affect vaginal tissues and intimate skin^4,6.

Some women experience:

• Vaginal dryness
• Increased sensitivity
• Irritation or discomfort
• Changes during intimacy

These changes can make everyday comfort feel different than before, making gentle personal care especially important.

Skin Changes

Hormonal shifts may also affect the skin.

Some women notice^2,4:

• Increased dryness
• Greater sensitivity
• Changes in skin texture
• More noticeable irritation from products they previously tolerated well

Because the skin can become more reactive during this stage, choosing gentle, fragrance-free products may help support comfort.

Changes in Bladder Function

Some women experience changes in bladder health during perimenopause^1,4. This can include:

• Increased urgency
• More frequent trips to the bathroom
• Leakage during coughing, laughing, or exercise

These symptoms are relatively common and may become more noticeable as hormonal changes continue.

How Long Does Perimenopause Last?

The duration of perimenopause varies from person to person. For some women, the transition lasts only a few years. For others, symptoms may continue for longer before menopause is reached. There is no "normal" timeline that applies to everyone.

Supporting Yourself During Perimenopause

Although perimenopause is a natural life stage, that does not mean you have to simply put up with uncomfortable symptoms.

Many women find it helpful to⁷:

• Prioritise regular sleep habits
• Stay physically active
• Eat a balanced diet
• Manage stress where possible
• Keep track of symptoms and cycle changes
• Speak with a healthcare professional about any concerns

It can also help to choose gentle personal care products that support comfort when intimate skin becomes more sensitive.

When Should You Speak to a Healthcare Professional?

If symptoms are affecting your quality of life, it's worth seeking professional advice.

You should also speak to a healthcare provider if you experience^2,4:

• Very heavy bleeding
• Bleeding between periods
• Symptoms that feel sudden or severe
• Concerns about changes to your physical or emotional wellbeing

A healthcare professional can help determine whether symptoms are related to perimenopause or whether another condition may be contributing.

Final Thoughts

Perimenopause is a natural transition, but that does not make it any less significant. From menstrual changes and sleep disruption to hot flushes, mood shifts, and increased skin sensitivity, the experience can affect many parts of daily life.

Learning what is happening to your body helps make these changes easier to handle. When you know what symptoms to look for and get support when you need it, you can navigate perimenopause feeling more comfortable, confident, and gentle with yourself.
