Perimenopause is the transitional stage before menopause when hormone levels begin to fluctuate, this will often cause a wide range of physical and emotional symptoms. It usually starts in a woman’s 40s but can begin earlier and often lasts several years until periods stop completely. While perimenopause is a normal stage of life, its symptoms can feel overwhelming. To manage perimenopause symptoms effectively, combine healthy lifestyle changes with evidence-based supplements and, where appropriate, medical treatments guided by a healthcare professional.

 In this guide, we’ll explain what perimenopause means, highlight the most common signs, and explore effective ways to ease the transition naturally and with holistic support.

What is Perimenopause

Perimenopause represents the transitional period leading up to menopause, characterised by fluctuations in hormone levels. This phase is triggered by a gradual decline in oestrogen and progesterone as the ovaries decrease their egg release. The perimenopausal stage ends after a woman has experienced 12 consecutive months without menstruation. While it predominantly occurs in women in their 40s, it may commence earlier, and its length can vary, generally spanning from two to ten years.

"Perimenopause is not a sudden change but a gradual journey. Every woman experiences it differently, which is why understanding your body and seeking the right support is key. Small lifestyle adjustments, the right nutrition, and evidence-based treatments can make a real difference in how women feel during this transition." - Panasha Desai, Pharmacist at Landys Chemist

When does perimenopause happen and how long does it last?

Perimenopause usually begins between the ages of 40 and 44, though it can start earlier (late 30s) or later (mid-to-late 40s). The average duration is 4 to 8 years, but some women may experience it for as little as 2 years or as long as 10 years. Lifestyle, genetics, and overall health play a role in when it starts and how intense symptoms may be.

Menopause vs Perimenopause

Perimenopause is the transitional stage before menopause, when fluctuating hormones can cause irregular periods, hot flushes, and mood changes. Menopause occurs after 12 consecutive months without a period, marking the end of reproductive years as hormone levels settle at a lower baseline. Knowing the difference helps women recognise symptoms early and take steps to manage their health.

Signs of Perimenopause

Perimenopause affects both the body and mind. Perimenopause symptoms can range from mild to severe; for example, mild symptoms may include occasional hot flushes or slight changes in the menstrual cycle, while more severe symptoms could involve frequent, intense hot flashes, heavy periods, or significant mood swings that interfere with daily life.

Perimenopause symptoms:

• Hot flushes and night sweats that can disrupt daily life and sleep
• Vaginal dryness or discomfort during sex
• Irregular, lighter, or heavier periods
• Sleep disturbances and persistent fatigue
• Weight gain, bloating, and changes in body composition
• Thinning hair and dry, less elastic skin
• Mood swings, irritability, or heightened anxiety
• Brain fog, difficulty concentrating, and memory lapses

How to Manage Perimenopause Symptoms

Managing perimenopause can be effective when combining lifestyle strategies with supplements. Taking these steps early can help reduce the impact of symptoms and make the transition more manageable:

• Nutrition: Consume a balanced diet abundant in vitamins, minerals, and phytoestrogens. For natural hormone balance, consider incorporating phytoestrogen-rich foods such as soybeans, tofu, flaxseeds, chickpeas, and lentils into your diet.

• Exercise: Engage in regular physical activity to support bone and heart health, and to improve mood. Incorporate a mix of cardiovascular exercise, strength training, and yoga to promote bone density, energy, and emotional wellbeing.

• Stress Management: Utilise techniques like meditation, yoga, or deep breathing to manage stress effectively. Incorporate daily mindfulness exercises or brief guided meditations to manage mood and lessen anxiety throughout hormonal shifts.

• Sleep: Establish consistent routines and create a comfortable environment to prioritise sleep. Avoid screens before bed, keep your bedroom cool, and try herbal teas such as chamomile or lemon balm to support restful sleep.

• Lifestyle Choices: Limit alcohol consumption and abstain from smoking. Reducing alcohol and avoiding smoking can help stabilise hormones, support cardiovascular health, and ease symptoms such as hot flushes.

When To Consider Seeing A Doctor For Perimenopause?

While many perimenopause symptoms can be managed through lifestyle changes and supplements, it’s important to consult a doctor if symptoms become severe or interfere with daily life. Contact your doctor if you experience very heavy or erratic bleeding, persistent pelvic pain, sudden mood swings, or sleep issues that do not improve with self-care.
