How To Tell If You Are In Perimenopause or Menopause

Key takeaways

• Perimenopause is a transitional phase, marked by irregular periods and fluctuating hormones, while menopause is confirmed after 12 consecutive months without a period.
• Symptoms can overlap, including hot flashes, mood swings, sleep disturbances, and vaginal dryness.
• Tracking your menstrual cycle and symptoms helps determine which stage you’re in and informs treatment decisions.
• Treatment options include lifestyle changes, diet, exercise, stress management, non-hormonal therapies and hormone replacement therapy for severe symptoms.
• See a doctor if bleeding is very heavy or prolonged, symptoms interfere with daily life or menopause occurs unusually early.

If your periods are changing, your sleep feels off, or you’re suddenly dealing with hot flashes or mood swings, you might wonder what’s going on. These can be signs of perimenopause or menopause—a natural stage of life that every woman goes through, yet one that’s often misunderstood or overlooked.

Because the symptoms can be gradual and vary from person to person, it’s not always easy to tell where you are on this journey. Some may take a menopause test, track their menstrual cycles or see a doctor.

Understanding the difference between perimenopause and menopause can help you make sense of the changes in your body and know what to expect next.

What Is Perimenopause?

To begin, let’s define perimenopause and menopause. 

Perimenopause is the transitional period leading up to menopause. During this time, your ovaries produce fewer hormones, which can make your menstrual cycles irregular or unpredictable. It signals that your body is gradually moving toward the end of its reproductive years.

Here’s what to know about perimenopause:

• Timing: Perimenopause can begin in the mid-30s or even as late as the mid-50s.
• Hormonal changes: Ovaries still function, but estrogen and other hormone levels fluctuate unevenly. However, fertility doesn’t completely stop during perimenopause, so pregnancy is still possible.
• Menstrual changes: Periods may become irregular—shorter, longer, heavier, lighter or occasionally skipped.
• Duration: Perimenopause lasts differently for everyone. It can be a short phase or stretch on for years. Moreover, it only ends when you have gone 12 consecutive months without a period. At that point, you have officially reached menopause.

Essentially, the first real clue that you’re entering perimenopause is usually a change in your period. What used to be a predictable monthly routine might turn into random spotting or cycles that go missing entirely. 

It’s also very common to start dealing with menopause symptoms, like hot flushes and vaginal dryness, much earlier in the transition than you might expect.

What Is Menopause?

Menopause is the stage in a woman’s life when her menstrual cycles permanently stop. It marks the end of the reproductive years and occurs after a full year without a period. Your ovaries no longer release eggs, and estrogen production slows down.

Key things to understand about menopause:

• Timing: On average, Singaporean women reach menopause at 49, though it can occur anytime between 45 and 55. 
• Hormonal changes: Ovaries stop releasing eggs, and estrogen and progesterone levels drop significantly.
• End of menstruation: Periods cease completely; a year without a menstrual cycle confirms menopause. 
• Long-term health considerations: Lower estrogen affects how your body retains calcium and processes cholesterol, making long-term bone density and heart health a priority.
• Duration: Think of menopause as a specific milestone rather than a long-term state. You reach it once you’ve gone a full year without a period. After that, you move into postmenopause, which lasts for the rest of your life.

If menopause occurs as a result of surgery or certain medical treatments, it’s referred to as induced menopause.

Perimenopause vs Menopause: Key Differences

Now that we’ve defined perimenopause vs menopause, it’s helpful to see how the two stages differ. While they are part of the same natural transition, the changes in your body, hormone levels and symptoms can vary.

What changes	Perimenopause	Menopause
Menstrual cycle	Periods become irregular. You may still have predictable cycles in some months.	Periods have stopped completely for 12 consecutive months. No more menstrual cycles occur.
Hormone levels	Estrogen and progesterone levels spike and dip wildly from day to day.	Hormone production has permanently dropped to a consistently low level.
Fertility and pregnancy risk	Fertility declines, but pregnancy is still possible. Birth control is still necessary to avoid pregnancy.	Fertility ends. Pregnancy is no longer possible after menopause is confirmed.
Symptom patterns	Symptoms come and go in waves depending on your cycle.	Symptoms may continue or even intensify initially, but usually stabilise over time.

Common Symptoms of Perimenopause

As estrogen levels start to drop, your body needs to adapt to the hormonal changes. Everyone experiences it differently. Some people only notice changes in their periods, while others may deal with symptoms like hot flushes, night sweats or mood changes.

Most women find they encounter at least one common symptom, such as:

Irregular Periods

You might notice some periods are lighter or heavier, come sooner or later than usual or even be skipped altogether. 

If your cycle shifts by about a week or more regularly, it’s often a sign of early perimenopause. Experiencing gaps of 60 days or longer between periods usually points to late perimenopause.

Hot Flushes and Night Sweats

Hot flushes are a sudden, intense wave of heat that usually starts in the chest or face and spreads upward. Night sweats are simply hot flushes that happen while you sleep, often leaving your pyjamas or sheets damp.

Mood Swings and Anxiety

Some women may experience sudden irritability, a short fuse or an unexplained sense of dread or anxiety that wasn’t there before. 

Sleep Problems

You might find it impossible to fall asleep, or you wake up at 3:00 AM wired and unable to drift back off. This often happens even if you aren’t experiencing night sweats.

Breast Tenderness

Your breasts may feel swollen, heavy or painfully sensitive to the touch. Fluctuations in estrogen and progesterone levels are a common reason for breast tenderness during perimenopause.

Common Symptoms of Menopause

Because your estrogen levels have now settled into a permanently low state, you might notice a change in how symptoms manifest. They tend to be more about how your body’s tissues and systems function without their usual hormonal support.

Here are some common symptoms:

No Periods for 12 Months

The most definitive sign of menopause is the absence of menstrual periods for a full year. However, it’s common for periods to be irregular during the years leading up to menopause (perimenopause) before they stop completely.

Vaginal Dryness

Lower estrogen levels can make the vaginal lining thinner, drier and less elastic. This may cause discomfort or pain during intimacy. Some women also notice burning sensations or more frequent urinary tract infections. 

Joint Pain and Stiffness

Estrogen acts as a natural anti-inflammatory and helps regulate fluid levels in the joints. Without it, inflammation can increase, and the cartilage can lose some of its cushion.

This is why you might wake up with stiff knees, achy hips or sore fingers that take a while to warm up during the day.

Weight Changes

Menopause weight gain is common, even if your diet and activity level haven’t changed. Hormonal shifts can slow metabolism and encourage fat to settle around the abdomen. Muscle mass also naturally decreases with age, which can make weight management harder. 

Brain Fog

Brain fog during menopause can feel like your mental sharpness is being muted. You might misplace things more often or struggle to recall words. Hormonal changes, poor sleep and stress can all contribute.

How to Tell if You Are in Perimenopause or Menopause

It’s not always easy to know whether you’re in perimenopause or menopause. Both share similar symptoms, but a few key clues can help you tell the difference. Here’s what to look at:

Tracking Your Menstrual Cycle

Keeping track of your periods can help you spot patterns and changes over time. Even if your cycle feels unpredictable, noting when your period starts, how long it lasts and any unusual bleeding can give you a clearer picture of what’s happening.

A tracking app or simple calendar works well for this. 

Understanding Symptom Timing

Pay attention to how your symptoms appear and change. 

• Perimenopause: Symptoms often come and go. You might have weeks where you feel normal, followed by times with hot flashes, mood swings or sleep issues. This is due to hormones rising and falling unevenly.
• Menopause: Symptoms may still be present, but they are linked to consistently low estrogen rather than hormonal swings. 

If your symptoms feel unpredictable and your periods haven’t fully stopped, you’re likely in perimenopause.

Hormone Testing

Some women consider taking a menopause test to get clarity about where they are in the transition. It looks at hormone levels as well as overall health markers. These may also include checks for bone density and cardiovascular health, since menopause can affect more than just reproductive hormones.

Age and Health History Clues

Your age and medical background can provide helpful context.

• Family History: Your mother’s or sisters’ age at menopause is often a good predictor of your own timeline.
• Lifestyle Factors: Smoking, certain autoimmune conditions or a history of chemotherapy can lead to an earlier onset.

Can You Be in Perimenopause and Menopause at the Same Time?

It’s a very common question, but the short answer is no.

Perimenopause and menopause are two different stages of the same transition, but they don’t happen at the same time. What makes it confusing is that the symptoms can overlap, and the shift from one stage to the next isn’t always obvious.

Often, the term menopause is used to describe both the transition and the point when periods stop, but technically, the phase leading up to the end of menstruation is called perimenopause. Menopause itself begins once your periods have fully stopped.

Treatment Options for Perimenopause vs Menopause

Managing symptoms during this transition is possible with the right approach. Let’s look at the options for perimenopause treatment, as well as for menopause.

Lifestyle and Symptom Management

Tracking symptoms and maintaining healthy routines can reduce hot flashes, sleep problems and mood changes.

Diet

Focus on calcium, vitamin D, fruits, vegetables, whole grains and healthy fats. Limit caffeine, alcohol and processed foods.

Exercise

Regular aerobic activity and strength training support weight, mood, bone and heart health.

Stress Management

Mindfulness, yoga, meditation, hobbies and short daily routines help manage anxiety and improve well-being.

Non-Hormonal Medications and Therapies

For women with more severe symptoms, doctors may recommend non-hormonal medications. For example, certain antidepressants (SSRIs or SNRIs) can be prescribed for hot flushes and mood changes.

Other options, such as vaginal moisturisers or lubricants, can also relieve vaginal dryness.

Hormone Therapy

HRT may be recommended for severe symptoms, tailored to your health history and needs. Consult a healthcare provider to see if it’s right for you.

When to See a Doctor

Some signs mean it’s time to consult a healthcare provider. See a doctor if you notice:

• Very heavy or prolonged bleeding that’s different from your usual cycle
• Symptoms affecting daily life, like severe hot flashes, sleep issues or mood swings
• Early or premature menopause before age 40, which can affect fertility and long-term health
