• The most common perimenopause symptoms include hot flushes, fatigue, sleep disruption, mood changes, and weight gain

• These symptoms are driven by fluctuating oestrogen and progesterone levels

• Nutrition, strength training, stress management, and sleep support can significantly reduce symptoms

• Small, consistent daily habits have the biggest impact

What are the most common perimenopause symptoms?

The most common perimenopause symptoms include:

• Hot flushes and night sweats

• Irregular periods

• Fatigue

• Brain fog and memory lapses

• Mood changes

• Sleep disruption

• Weight gain (especially around the midsection)

• Vaginal dryness and reduced libido

• Hair, skin, and nail changes

• Increased emotional sensitivity

Perimenopause can feel like your body is suddenly working against you. Mood swings, sleep disruption, fatigue, and weight changes may leave you feeling overwhelmed, frustrated, and confused. Let’s talk about the 10 most common perimenopause symptoms and how you can take control of your health, energy, and mood.

1. Hot Flushes and Night Sweats

Hot flushes or night sweats are common, uncomfortable, can be embarrassing and can disrupt sleep. A hot flush is a sudden feeling of heat, often accompanied by sweating, flushing, or heart palpitations. They occur because the fluctuation in oestrogen affects your body’s temperature regulation mechanism.

What helps:

• Dressing in layers to allow for easy ways to cool quickly as a practical measure

• Keeping your bedroom cool to reduce overheating

• Avoid triggers which for many women include alcohol, caffeine and spicy foods

• Hot flushes can also be triggered by anxiety so behaviours such as mindful breathing can help reduce the frequency and lessen the intensity of a hot flush

2. Irregular Periods

During perimenopause your menstrual cycle may become shorter, longer, heavier, or lighter. All of these are normal! Fluctuations in oestrogen and progesterone stop the ovulation cycle. Without ovulation, the hormonal pathway to getting our period is also stopped. Periods are irregular however because these hormones are fluctuating - sometimes they produce the right amounts for ovulation to occur and sometimes they don’t.

What helps:

• Track your cycle to identify patterns so you can see how your hormones are shifting

• Eat plenty of protein to support hormone production, healthy fats to assist with hormone synthesis, and phytoestrogens to gently support oestrogen levels

• Manage stress and prioritise sleep to help protect hormone balance

If your periods are irregular in a way that is severe and disrupts your daily life, speak to your doctor. This might include flooding, pain that disrupts your daily life, or any other irregularity that concerns you.

3. Fatigue

Feeling exhausted is common in perimenopause, even if your sleep quality and quantity is adequate. Exhaustion has many causes during this time and it is important to practice self care. Exhaustion may be due to hormone fluctuations, stress, sleep disruption, and nutrient imbalances.

What helps:

• Prioritise protein at every meal and enjoy balanced meals that include complex carbohydrates, protein and healthy fats

• Focus on restorative sleep which includes going to be earlier and winding down before bed time

• Include gentle movement and stress-management practices in your daily routine

4. Brain Fog and Memory Lapses

Trouble focusing, forgetfulness, or difficulty concentrating are all common during perimenopause. It happens because Oestrogen plays a key role in brain function, including memory and cognition. The decline of this hormone during perimenopause can cause brain fog and memory lapses.

What helps:

• Break tasks into smaller steps and use notes to keep you on track

• Maintain a routine which enables you to operate out of habit and structure

• Include nutrient rich foods such as omega 3 fatty acids

• Ensure you are eating adequate protein (especially at breakfast)

5. Mood Changes

Irritability, anxiety, low mood, or emotional sensitivity are all common but they don’t need to be a part of your experience. Our neurotransmitters that regulate mood are impacted by the hormonal shifts that occur during perimenopause.

What helps:

• Mindfulness, meditation, and breathing exercises help to keep mood stable

• Talk therapy can help if feelings become overwhelming

• Regular exercise boosts endorphins and stabilises mood

• Strength training (lifting weights) can dramatically impact your mood

6. Sleep Disruption

Difficulty falling asleep, staying asleep, or waking up unrefreshed are reported as some of the most common and frustrating symptoms of perimenopause. It can sometimes seem that the harder you try to fall asleep, the worse it becomes. It occurs because night sweats, cortisol imbalances, and low progesterone interfere with our ability to relax and fall into deep sleep.

What helps:

• Establish a calming bedtime routine

• Keep your sleep environment cool and dark

• Avoid late-night caffeine and sugar

• Ensure you eat enough protein in your dinner meal to keep you full overnight

• Use supportive practices such as meditation and yoga nidra to calm the mind

7. Weight Gain, Especially Around the Midsection

Unexplained weight gain, particularly belly fat, occurs during perimenopause due to a decline in oestrogen and an increase in cortisol, which encourages the storage of fat around the abdomen. Muscle loss and metabolic changes also both contribute to how fat is stored as we age.

What helps:

• Resistance training to maintain muscle

• Balanced meals with high protein and fibre and minimise naked carbs

• Reduce sugar and processed foods

• Manage stress and sleep, both of which affect hormones

• Exercise in the ‘weight loss’ heart rate range to help lose weight if this is your goal

8. Vaginal Dryness and Changes in Libido

Vaginal dryness, discomfort, and reduced sexual desire occur because declining oestrogen affects vaginal tissue, lubrication, and blood flow to the region. This can cause tension in a relationship so letting your partner know this is normal helps to remove the feelings of rejection that may occur.

What helps:

• Water-based lubricants

• Regular sexual activity and pelvic floor exercises

• Discuss options like topical oestrogen with your healthcare provider

• Talk to your partner and rekindle intimacy in ways that feel good rather than relying on sexual desire to maintain a physical relationship

9. Hair, Skin, and Nail Changes

Physical changes such as thinning hair, dry skin, brittle nails, or slower nail growth can impact the way we see ourselves during perimenopause. Hormonal changes impact collagen production and hair follicle growth and stress can also cause hair loss.

What helps:

• Collagen-rich foods or supplements

• Drink plenty of water as hydration and a gentle skincare routine both affect skin appearance

• Nutrients like zinc, vitamin C, and biotin help to support these changes

10. Hot Emotional Reactions or Feeling Overwhelmed

Feeling unusually emotional, reactive, or “on edge” is very common and this is a time for extreme self-care. Hormonal fluctuations, stress, and the mental load that women often carry during this time in our lives can amplify emotions.

It is normal to feel this way but it doesn’t have to be your experience.

What helps:

• Prioritise self-care and stress management (think an early bedtime, time out to read a book or go for a walk with a friend, having a massage or a bubble bath)

• Set boundaries with work and family demands (assign tasks to others if you can)

• Connect with supportive friends or groups
