The Age of Onset of Menopause

Menopause is a significant life stage, marking the end of a woman's reproductive years. Understanding the onset factors, associated health risks, and how to maintain a healthy lifestyle during this transition is crucial for managing this phase effectively. Amira worked on that topic to understand from where it comes and how it works. 

What is Menopause?

Menopause occurs when a woman's ovaries cease to function, leading to the end of menstruation. For those still in the previous phase you can also be interested in Hot Flashes during your periods. Medically, menopause is diagnosed after a woman has gone 12 consecutive months without a period, indicating the end of ovulation and a significant decrease in estrogen and progesterone levels. 

This phase often brings various symptoms, including hot flashes, night sweats, joint pain, vaginal dryness, urinary incontinence, and mood swings, all due to the hormonal shifts. These symptoms can vary greatly in intensity from one woman to another. It's important to consult with a gynecologist if these symptoms significantly impact your life, as there are treatments available. Additionally, menopause is linked to increased risks of cardiovascular diseases and osteoporosis, making it essential to maintain a healthy lifestyle during this period.

If you want to know more on menopause, we started with the basics on one of our very first article : Menopause 101.

What is the Average Age of Menopause?

In the United States, the average age for a woman to reach menopause is around 51 years. Most women in developed countries enter perimenopause, the transition leading up to menopause, marked by irregular periods at an average age of 47.5 years.

As you can guess these datas are global and every person is reacting in a different way to stages of life so it can occure earlier or later. You could ask yourself what is the Maximum Age of Menopause? Generally, women experience menopause between the ages of 45 and 55, but as explained this can vary widely and the age of onset can differ by up to 4.4 years due to individual factors.

How to Determine When You Will Reach Menopause

Predicting the exact age at which menopause will occur is challenging. However, certain symptoms such as weight gain, sleep disturbances, hot flashes, and genitourinary syndrome (which includes vaginal dryness and urinary issues) are more indicative of menopause than perimenopause. Women experiencing these symptoms can find support and resources through Amira's Blog to better manage these changes.

Amira's mission is to help women to go through this step of life and this is why we created Terra to prevent and combat hot flashes at night. We developped a certain expertise about Menopause and if you want to talk about your situation, try Terra or ask us question about our goal you can also reach out to us, we will be very happy to talk to you !

How to Identify Menopause Without Relying on Menstrual Changes

Menopause is typically confirmed after 12 consecutive months without menstruation for women over 40. However, this method isn't always applicable. For instance, women who have undergone a hysterectomy no longer menstruate but may still ovulate, making it hard to diagnose menopause based solely on the absence of periods. In such cases, symptoms like hot flashes, sleep disturbances, and vaginal dryness, or consecutive hormone tests, can help diagnose menopause. Women on contraception that stops or alters their menstrual cycle may also need to discontinue its use or undergo blood tests to check for ovulation.

Explaining the Variation in Menopause Onset Among Women

Sociodemographic Factors

Research indicates that the age of menopause onset can differ based on sociodemographic factors. Women in developing countries tend to reach menopause earlier than those in developed nations. Additionally, women living in rural areas generally experience menopause sooner than those in urban areas. Ethnicity also plays a role; women of African or Latin American descent typically reach menopause about two years earlier than Caucasian women, while Asian women tend to have menopause at the same average age as Caucasian women (around 50-51 years).

Menstrual Cycle Length Between Ages 20 and 35

A study from 1967 revealed that the length of menstrual cycles earlier in life could influence the age of menopause onset:

• Women with menstrual cycles shorter than 26 days between ages 20 and 35 reached menopause 1.4 years earlier on average than those with a "normal" 28-day cycle.
• Conversely, women with cycles longer than 33 days during this period experienced menopause 0.8 years later on average.

Maternal Age of Menopause

Studies suggest that a woman's age at menopause may be influenced by her mother's age at menopause. Genetic research on European women has identified chromosomes with genes that could play a role in determining the timing of menopause.

Smoking and Menopause Age

Smoking is a well-documented factor that accelerates menopause onset. Studies indicate that smokers reach menopause one to two years earlier than non-smokers. Additionally, smokers tend to have a shorter perimenopausal phase. Passive smoking has similar, though less pronounced, effects. Smoking may cause ovarian follicle atrophy, and the impact is proportional to the amount of tobacco consumed. Women who quit smoking tend to experience menopause later than current smokers but slightly earlier than non-smokers.

Alcohol Consumption and Menopause Age

A 2016 Oxford Academy study concluded that moderate alcohol consumption (1 to 3 drinks per week) is associated with a later onset of menopause compared to non-drinkers.

The Case of Premature Ovarian Insufficiency

Premature ovarian insufficiency (POI) occurs when ovarian function ceases before age 40, leading to menopause-like symptoms. Causes of POI include toxic exposures, autoimmune mechanisms, genetic factors, and treatments such as radiotherapy, chemotherapy, or surgery. Women experiencing early menopause (before age 40 or 45) are often recommended hormone replacement therapy (HRT) to mitigate the risks of osteoporosis and cardiovascular disease associated with early menopause. Women with POI can join the Amira community to connect with others facing similar challenges and access expert advice.

The Impact of Menopause Age on Health

Cardiovascular Risks

Before menopause, women have a lower cardiovascular risk compared to men, but this advantage diminishes post-menopause, leading to more severe complications. Estrogen has protective effects on the cardiovascular system, including:

• Inhibiting the formation of free radicals that react with LDL cholesterol to form atherosclerotic plaques.
• Maintaining the structural integrity of the myocardium.
• Favorably modifying glucose and lipid profiles, reducing insulin resistance.
• Benefiting the vascular endothelium and promoting angiogenesis.
• Modulating vasoconstriction and vasodilation processes, thus supporting healthy blood circulation.

Later menopause extends the protective effects of estrogen. Studies have shown that women who reach menopause at age 52 or older have an 18% lower cardiovascular mortality rate compared to those who reach it at 44 or earlier. Women experiencing early menopause should be closely monitored by healthcare providers to manage cardiovascular risks. Hormone replacement therapy is one approach to extend the protective effects of estrogen.

Osteoporosis

Research indicates that women who reach menopause earlier are at a higher risk of developing osteoporosis, a condition that weakens bones and increases the risk of fractures. Estrogen plays a crucial role in bone formation and remodeling. The length of the reproductive period (from first menstruation to menopause) influences osteoporosis risk, with longer reproductive periods being associated with a lower risk.

Endometrial and Ovarian Cancer

Cancers of the breast, ovaries, and endometrium are hormone-dependent, stimulated by the presence of estrogen. Therefore, earlier menopause, which results in an earlier decline in estrogen, provides some protection against these cancers, which typically develop around age 50.

Hormone Replacement Therapy (HRT) and Menopause Age

HRT is the most effective treatment for alleviating menopause-related symptoms such as hot flashes, sleep disturbances, genitourinary syndrome, and joint pain.

Even though Amira will never recommend to take hormonal solution it said that for women experiencing early menopause, HRT is recommended to protect bones and the heart. Women reaching menopause around the average age of 51 can also benefit from HRT if they have symptoms and no history of cardiovascular disease or breast cancer.

In countries like France, HRT is prescribed within 10 years of menopause onset to minimize the increased risk of breast cancer while providing significant benefits for bone and cardiovascular health and symptom relief. For women experiencing late menopause, HRT can still be prescribed, though careful monitoring is needed due to the longer lifetime exposure to estrogen.

Hot Flashes and Sleep Disruption During Menopause

Hot flashes are among the most bothersome symptoms of menopause, significantly impacting women’s quality of life. These sudden, intense waves of heat can occur at any time but are particularly disruptive during sleep, leading to frequent awakenings and poor sleep quality. Night sweats, a form of hot flashes occurring at night, further exacerbate sleep disturbances. As a result, many women experience chronic sleep deprivation, which can affect overall health and well-being. For those struggling with hot flashes and sleep disturbances, Amira offers solutions designed to help women manage these symptoms and improve sleep quality. Our innovative product Terra, is a highly effective tool for tackling this issue, allowing women to navigate menopause with greater ease and comfort. 

Conclusion

Understanding the age of menopause onset, its associated risks, and how to manage this life stage is crucial for maintaining overall health and well-being. By staying informed and proactive, women can navigate menopause with confidence and continue to lead a healthy, fulfilling life.
