A Peuriste Guide to Navigating Every Phase of Your Journey
Your menstrual cycle is not static. It evolves alongside you, shifting and changing as you move through different decades of life. What is normal for a teenager may signal something entirely different for a woman in her forties.
According to experts at Singapore General Hospital (SGH), period problems typically occur in the very young or older women. For girls who have just begun menstruating, it is like a new factory starting production. They may initially have irregular cycles that usually improve as the body gets more efficient. Women in their late 40s or early 50s often experience irregular, heavy or prolonged periods as a result of hormonal changes brought about by impending menopause.
Understanding these changes is empowering. It helps you distinguish between natural transitions and warning signs that warrant medical attention. It also helps you choose the right products and self care practices for each stage.
At Peuriste, we believe in supporting women through every phase of life. Here is what you need to know about menstrual health from your first period through perimenopause and beyond.
Ages 10 to 17: The First Period Journey
The arrival of a first period is a milestone moment. For most girls, this happens during adolescence, and understanding what to expect can make the transition smoother.
What to Expect
For adolescents, menstrual cycles are often irregular as the body establishes its rhythm. KK Women's and Children's Hospital (KKH) has a dedicated Adolescent Gynaecology Clinic that manages gynaecological health for girls aged 17 years and below . The range of cases seen includes primary amenorrhoea (absence of menses), delayed puberty, secondary amenorrhoea, abnormal menstrual cycles (irregular and heavy menses), and uterovaginal malformations.
As Assoc Prof Yong Tze Tein, Head and Senior Consultant at the Department of Obstetrics and Gynaecology, SGH, explains: "For girls who have begun menstruating, it's almost like a new factory starting to get into production. They may initially have irregular cycles that usually improve when the 'factory' gets more efficient. Sometimes, they may get period pain which lessens as they grow older".
Supporting a Young Girl Through Her First Period
Choosing the right products can make a significant difference. Pads are often the easiest option for young girls beginning their period journey. They are simple to use and non invasive. Period underwear is another excellent option, providing absorbent protection that feels just like normal underwear and offers peace of mind for girls worried about unexpected staining.
The National University Hospital (NUH) provides comprehensive care for teenagers through their Division of Benign Gynaecology, offering services that include caring for teenagers with gynaecological concerns .
When to Seek Help
Parents should seek medical attention if a girl's period has not started by an appropriate age or if there are concerns about development. KKH's Adolescent Gynaecology Clinic is specifically designed to address these concerns and provide specialist care for young girls.
Ages 20 to 30: Hormonal Shifts and Stress
Your twenties and thirties are often the most predictable years for menstrual cycles, but they also bring unique challenges.
What to Expect
During these decades, women may become more prone to growths in the womb and ovaries. According to SGH, when women reach their late 30s, they become more prone to developing fibroids (solid benign tumours that grow from the muscle of the womb) or adenomyosis (which occurs when the lining of the womb infiltrates its muscular wall). Endometriotic cysts, or blood cysts, are thought to result from the reversed flow of menstrual blood through the fallopian tube into the pelvic cavity and ovaries.
Fibroids are particularly common, with one in five women likely to have them at some point.
Polycystic Ovary Syndrome (PCOS)
PCOS is the most common hormonal disorder among women of reproductive age, affecting about 10 percent of women. Symptoms and signs include:
Women with PCOS are at higher risk of developing type 2 diabetes, heart attack and stroke at a much younger age. More than 50 percent of women with PCOS will have diabetes or pre-diabetes before the age of 40. Additionally, 40 percent have calcification in the coronary arteries before 45 years old (compared to 20 percent of women without PCOS), and they have a 50 percent increase in coronary events such as heart attacks.
Treatment Options
NUH outlines several treatment approaches for PCOS depending on the individual's primary concerns:
When to Seek Help
NUH's Division of Benign Gynaecology provides care for conditions including PCOS, endometriosis, abnormal menstrual bleeding, and pelvic pain . Women experiencing irregular periods, heavy flows, or intense pain should consult a healthcare provider.
Ages 40 to 50: Perimenopause and Transition
The forties mark a significant transition. Perimenopause, the time before menopause, typically begins eight to ten years before menopause, most commonly starting in a woman's 40s.
What Singaporean Women Experience
According to Mount Elizabeth Hospitals, perimenopause can begin eight to 10 years prior to menopause when ovaries begin to produce less oestrogen. The decrease in oestrogen speeds up during the last two years of perimenopause. At this point, many women will start to experience menopause symptoms, though they continue to have menstrual cycles and can still get pregnant.
The average age for women entering menopause is 51, though it can happen as early as their late 40s. As menopause is thought to be genetically determined, a woman may start to enter menopause around the same age their mother did.
Farrer Park Hospital notes that the number of Singaporean women aged 80 and above has risen significantly, meaning an increasing number of women will spend approximately 36 percent of their lives in postmenopause.
What to Expect
During perimenopause, hormone levels fluctuate significantly. Common symptoms include:
Irregular periods: Periods may become shorter or longer, and flow may become heavier or lighter. According to SGH, women in their late 40s or early 50s often experience irregular, heavy or prolonged periods, or spotting in between periods, as a result of hormonal changes.
Hot flushes and night sweats: These are sudden sensations of intense heat all over the body, particularly in the upper part such as the face and neck, sometimes accompanied by red blotches on the chest, back, and arms, sweating, rapid heartbeat, nausea and dizziness.
Muscle and joint pain: Aches, weakness or stiffness caused by reduced oestrogen levels, stress or tension, and a lack of exercise.
Sleep difficulties: Poor sleep is usually caused by night sweats but can also be a symptom of anxiety or depression.
Vaginal changes: The vaginal lining becomes drier, thinner and less elastic, which may make sexual intercourse uncomfortable or painful. The skin around the vaginal opening may become dry and thin, causing discomfort or itching.
Mood changes: Women may experience mood swings, from sadness and low self-esteem to irritability and frustration.
Long-Term Health Considerations
After menopause, reduced oestrogen levels can lead to several health considerations:
Bone health: Bone mass can decrease significantly during menopause. According to Farrer Park Hospital, bone mass can decrease by as much as 20 percent during menopause, which together with reduced muscle strength may raise the risk of falls and fractures later in life.
Heart health: Oestrogen helps keep blood vessels more elastic and improves endothelial function. After menopause, as oestrogen levels decrease, arteries gradually become stiffer, allowing plaque to build up more readily within blood vessels. Cholesterol profiles may worsen, with 'bad' cholesterol (LDL) increasing while 'good' cholesterol (HDL) decreases.
Weight management: Reduced hormone levels can affect the body's ability to regulate weight, and menopausal women may find themselves putting on weight despite consuming the same amount of food.
Managing Perimenopause
Treatment approaches may include:
Lifestyle modifications: Regular physical activity, together with a healthy and balanced diet rich in phytoestrogens (soybeans, tempeh, miso, legumes, flaxseeds), whole grains, and adequate amounts of dietary calcium and protein, may help alleviate symptoms while supporting bone health.
Hormone replacement therapy (HRT): HRT is prescribed with the goal of relieving symptoms like hot flashes, night sweats, vaginal dryness and improving bone density. For women with a uterus, progesterone is needed alongside oestrogen to protect the womb lining.
Non-hormonal treatments: Options such as fezolinetant may help manage hot flashes and night sweats by blocking the pathway in the brain responsible for body temperature regulation.
When to Seek Help
Women should consult their gynaecologist if they experience menopausal symptoms before age 45, vaginal bleeding after reaching menopause (which is abnormal and may be a sign of endometrial hyperplasia or uterine cancer), or have difficulty managing physical or emotional symptoms.
Mount Elizabeth Hospitals advises that while some women transition easily into menopause, others may have symptoms that are incredibly difficult to deal with and may affect them physically, emotionally and mentally. In more challenging instances, help may be needed from a doctor to help manage the symptoms.
How Product Needs Evolve Across Life Stages
Just as your cycle changes, your product needs evolve throughout your life.
Teens and first periods: Comfort and simplicity matter most. Pads provide reliable protection without complexity. For young girls with sensitive skin, choosing organic period pads made from gentle, breathable materials can help prevent irritation during this adjustment period. Products that feel approachable rather than intimidating help young girls navigate this transition with confidence.
Twenties and thirties: Lifestyle integration becomes important. Women balancing careers, relationships, and potentially motherhood need products that fit active lives. Many Singapore women are now turning to bamboo sanitary pads and period underwear options for their combination of softness, absorbency, and eco-conscious design. Some may explore period swimwear for specific activities. The focus shifts to products that offer security without compromising comfort.
Perimenopause and beyond: Unpredictability becomes the norm. With cycles varying in length and flow, having a range of options at hand provides peace of mind. Products that accommodate both heavy flow days and light spotting become essential. Skin sensitivity may increase during this stage, making breathable, gentle materials more important than ever. This is why many women in transition seek natural period products that minimise exposure to chemicals, fragrances, and synthetic materials.
At Peuriste, we understand that one size does not fit all when it comes to menstrual health. Your needs are as unique as your journey, and they deserve products that honour every stage of life.
Listening to Your Body at Every Age
Your menstrual cycle is a lifelong conversation between your body and you. By understanding what is typical for your age and stage, you become better equipped to notice when something feels different.
As Assoc Prof Yong reminds us: "Adenomyosis and fibroids are benign conditions. If you have an enlarged uterus but a normal period, there is no need to have any treatment. But we don't believe women should suffer from their periods. If they have heavy or painful periods, they should seek treatment" .
Whether you are a mother guiding your daughter through her first period, a professional navigating the demands of your thirties, or a woman approaching menopause with questions, knowledge is your greatest ally.
At Peuriste, we are here to support you with education, compassion, and products designed for every chapter of your story. Your body speaks to you throughout your life. Learning to listen is one of the most powerful things you can do for your health.
