The menopausal transition is a significant and inevitable phase in a woman’s life, marking the end of reproductive capability. It is a complex process that involves dramatic hormonal shifts and a variety of physical and emotional symptoms.
This transition is typically divided into two stages: perimenopause, the phase leading up to menopause when hormonal fluctuations begin, and post menopause, which starts after a woman has experienced 12 consecutive months without a menstrual period. During this time, the decline in oestrogen levels can lead to a wide range of symptoms, some of which can greatly impact quality of life. For healthcare practitioners, it is essential to have a comprehensive understanding of these changes to provide effective support and care for women going through this transition.
The objective of this mini review is to offer a thorough examination of the endocrine changes, symptomatology, and non-pharmacological approaches to managing menopausal symptoms. In doing so, healthcare providers can ensure a more holistic and patient-centred approach, recognising that the experience of menopause varies significantly among women.
Physiological and Clinical Aspects of Menopause
Hormonal Changes
The menopausal transition is fundamentally driven by changes in ovarian function. During a woman’s reproductive years, the ovaries produce oestrogen and progesterone, two hormones essential for regulating the menstrual cycle and maintaining various aspects of health. As a woman approaches menopause, the ovaries begin to lose their ability to produce these hormones efficiently. This decline in ovarian function leads to erratic ovulation and fluctuating oestrogen levels, characteristic of perimenopause. Eventually, the ovaries cease releasing eggs altogether, leading to the cessation of menstruation[1].
One of the hallmark features of menopause is the decline in follicle-stimulating hormone (FSH) levels, which plays a critical role in the development of ovarian follicles. In response to declining ovarian function, the pituitary gland increases FSH secretion, but the ovaries are less responsive to this signal as they enter a state of hormonal dormancy. This process leads to the cessation of oestrogen and progesterone production, which is directly responsible for the various symptoms and clinical manifestations of menopause[2].
Perimenopause
Perimenopause, often beginning in a woman’s 40s, is marked by irregular ovulation and varying levels of oestrogen. These hormonal fluctuations can last for several years, during which time women may notice changes in their menstrual cycles. Some women experience shorter cycles, while others may have heavier or lighter periods. This phase is accompanied by symptoms such as hot flashes, night sweats, vaginal dryness, and mood swings, among others[3].
The severity and duration of perimenopausal symptoms can vary widely among women. Some women may only experience mild discomfort, while others may face debilitating symptoms that interfere with daily life. Sleep disturbances and cognitive changes, including issues with memory and concentration, are common complaints during this time as are migraines[4]. Emotional health can also be affected, with many women reporting feelings of anxiety, depression, or irritability. These symptoms are largely attributed to the erratic fluctuations in oestrogen levels that occur during perimenopause[5].
Post menopause
Postmenopause is the period that follows the final menstrual period. Oestrogen levels remain low, and many of the symptoms experienced during perimenopause may continue, although they often diminish in intensity over time. However, the long-term consequences of low oestrogen levels become more apparent during this phase. Osteoporosis, cardiovascular disease, and genitourinary syndrome of menopause (GSM) are all more prevalent in postmenopausal women due to the protective effects of oestrogen no longer being present[6].
Osteoporosis, for example, is a condition characterised by a reduction in bone density, making bones more fragile and susceptible to fractures. Oestrogen plays a critical role in maintaining bone health by inhibiting the activity of osteoclasts, the cells responsible for bone breakdown. As oestrogen levels decline, bone resorption outpaces bone formation, leading to a net loss in bone density. Studies indicate that postmenopausal women are twice as likely to develop osteoporosis compared to their premenopausal counterparts[7].
Cardiovascular disease also becomes more of a concern after menopause. Oestrogen has been shown to have protective effects on the cardiovascular system, including improving cholesterol levels and maintaining the flexibility of blood vessels. The decline in oestrogen post menopause leads to an increased risk of heart disease, with studies suggesting a 20-30% increase in risk[8].
Genitourinary syndrome of menopause (GSM) refers to a collection of symptoms affecting the genital and urinary systems, including vaginal dryness, urinary urgency, and increased susceptibility to infections. These symptoms are a direct result of the thinning of vaginal and urethral tissues due to decreased oestrogen levels. GSM affects up to 70% of postmenopausal women and can have a significant impact on sexual function and quality of life[9].
Symptoms and Risks Associated with Menopause
The symptoms associated with menopause vary widely in their severity and duration, but some of the most common include:
| Symptom | Prevalence |
| Hot Flashes | 80% |
| Night Sweats | 60% |
| Vaginal Dryness | 50% |
Hot flashes and night sweats are among the most commonly reported symptoms. Hot flashes are sudden feelings of warmth that can spread throughout the body, often accompanied by sweating and a rapid heartbeat. They can occur at any time, but night sweats, which occur during sleep, can be particularly disruptive. These vasomotor symptoms are thought to be caused by the hypothalamus, the part of the brain that regulates body temperature, becoming more sensitive to small changes in temperature due to fluctuating oestrogen levels which can be effectively modulated with food concentrates[10].
In addition to the commonly experienced symptoms, menopause also carries an increased risk for certain chronic conditions, as shown below:
| Disease | Risk Increase |
| Osteoporosis | 2-fold |
| Cardiovascular Disease | 20-30% |
| Genitourinary Syndrome of Menopause (GSM) | 0-70% |
These increased risks necessitate a proactive approach in the management of postmenopausal women, with a particular focus on bone health, cardiovascular monitoring, and the management of GSM.
Non-Pharmacological Therapeutic Approaches
Given the range of symptoms and risks associated with menopause, a variety of non-pharmacological interventions have been explored to alleviate symptoms and improve quality of life. While hormone replacement therapy (HRT) has long been a standard treatment for menopausal symptoms, concerns over its long-term safety, particularly regarding breast cancer and cardiovascular risks, have led many women to seek alternatives. Non-pharmacological approaches provide a viable option for women who either cannot or prefer not to use HRT. Dysbiosis and the relationship between the microbial health of the gastrointestinal tract has started to demonstrate a close relationship between the microbes and the risk of menopause-related conditions, indicating that the use of pre and probiotics may confer a benefit[11].
Lifestyle Modifications
Regular exercise has been shown to be beneficial in reducing the frequency and severity of hot flashes. Exercise is thought to help regulate the body’s thermoregulatory system, making it less susceptible to the temperature fluctuations that trigger hot flashes. Additionally, exercise improves overall health, helps maintain a healthy weight, and reduces the risk of cardiovascular disease, which is of particular concern post menopause[12].
A healthy diet rich in fruits, vegetables, and whole grains is another important aspect of managing menopausal symptoms. Diets high in phytoestrogens, which are naturally occurring compounds in plants that mimic the effects of oestrogen, may help alleviate some symptoms. Foods such as soy, flaxseeds, and legumes are good sources of phytoestrogens and have been shown to provide modest relief from hot flashes and other symptoms[13].
Mind-Body Therapies
Cognitive-behavioural therapy (CBT) has been proven effective in managing the mood-related symptoms of menopause, including anxiety and depression. CBT helps women develop coping strategies and challenge negative thought patterns that can exacerbate symptoms. Studies have shown that CBT can also reduce the severity of hot flashes and improve sleep quality[14].
Yoga and meditation are increasingly popular mind-body therapies for managing stress, improving sleep, and enhancing overall well-being. These practices focus on relaxation and mindfulness, which can help mitigate the effects of stress and reduce the frequency of hot flashes. Regular practice of yoga has also been shown to improve flexibility and strength, which can help counteract the physical changes associated with aging[15].
Food Supplements
Food supplements such as black cohosh, red clover, probiotics, isoflavones, omega-3 fatty acids and others are also commonly used to alleviate menopausal symptoms[16]. While some studies have shown that these supplements can provide relief, the evidence is mixed, and more research is needed to fully understand their efficacy and safety[17]. A combination of botanicals and grape seed extract, hops and succinic acid has been found helpful in the amelioration of hot flashes, and other nutrient combinations may be used alongside, to balance the changes in hormone fluctuations[18].
Conclusion
The menopausal transition is a complex phenomenon requiring comprehensive care from healthcare practitioners. By understanding the physiological and clinical aspects of menopause, common symptoms, and non-pharmacological therapeutic approaches, providers can develop individualised treatment plans tailored to each woman’s needs. While no single approach works for everyone, incorporating lifestyle modifications, mind-body therapies, and alternative treatments can significantly improve the quality of life for women navigating this critical stage of reproductive aging.
