Natural menopause
Natural menopause happens as part of the normal ageing process, typically between ages 45 and 55. It’s diagnosed once you haven’t had a period for 12 consecutive months, and it’s not caused by surgery or illness.1
Menopause is a major turning point in a woman’s life. It's not just the end of periods, but a whole-body transition that can affect your mood, memory, sleep, skin, and more. It's driven by a gradual decline in oestradiol (a form of oestrogen), which typically begins in your 40s and continues beyond your final period. This shift can bring a range of physical and emotional changes, from sleep disruption and brain fog to mood changes and hot flushes.1
While conversations around menopause are improving, it’s still not always clear where to turn for support or reliable information. That’s why we’re here: to help you understand what’s happening in your body, explore your hormone health, and access resources when you need them.
Menopause, defined as having no periods for 12 consecutive months, is a natural, age-related process driven by a gradual decline in the hormones that support the reproductive system, primarily oestrogen, but also progesterone and testosterone. These hormones play a vital role in various bodily functions like bone strength, brain function, mood regulation, and body temperature control.1
As you age, the number of egg-containing follicles in your ovaries decreases. With fewer follicles, hormone production begins to slow. The body attempts to compensate by increasing levels of follicle-stimulating hormone (FSH), but over time, the ovaries become less responsive, ovulation stops, and periods come to an end. Consequently, symptoms like hot flushes, sleep disruption, and longer-term changes like reduced bone density can arise.1
Menopause marks the end of your menstrual cycles and fertility. While for many women it happens naturally in their 40s or 50s, others may experience it earlier due to medical or environmental reasons.

Surgical menopause
When both ovaries are removed (often to treat or prevent cancer), hormone production stops suddenly. This triggers immediate menopause symptoms, regardless of age.2
Removing just one ovary (unilateral oophorectomy) doesn’t cause menopause but may bring it on slightly earlier.2
Medication-induced menopause
Some cancer treatments can damage the ovaries, either temporarily or permanently, reducing or stopping hormone production. This can trigger menopause earlier than expected.3
Medical conditions
Diseases like Addison’s disease, Hashimoto’s thyroiditis, and Grave’s disease can cause your immune system to mistakenly attack your ovaries, thereby inducing menopause early.5
Environmental exposure
Smoking is one of the most well-known environmental triggers for early menopause. Other factors like pesticides and phthalates (found in plastics and some cosmetics) may also disrupt hormones and speed up menopause.5

Understanding whether you’re going through menopause isn’t always straightforward, especially when symptoms begin gradually, often years before your periods stop. Speaking with a clinician about what you’re experiencing can offer valuable clarity. While menopause is a clinical diagnosis based on symptoms and life stage, a simple blood test can provide helpful insight into your hormone levels and support more informed conversations about what’s happening in your body.

Managing menopause isn’t about treating a condition, but about supporting the symptoms that come with hormonal changes, so you can feel more like yourself again. A clinician can help you understand your symptoms and explore the full range of support options. While Numan doesn’t currently offer HRT prescriptions, we can help you monitor your hormone levels and find the best treatment option for you, be it hormonal or non-hormonal.
