PMS or menopause? How to tell the difference (and why it matters)

PMS, or premenstrual syndrome, occurs during the second half of your cycle, after ovulation. Symptoms may include mood swings, headaches, food cravings, and restlessness. These symptoms typically subside once your period begins. The hormonal changes associated with PMS are temporary and cyclical.

Menopause, particularly perimenopause, is a longer process. Your body is preparing to transition out of its fertile years, accompanied by hormonal fluctuations that are no longer predictable. Symptoms such as mood swings, bloating, tender breasts, and trouble sleeping — familiar from PMS — can occur at any time of the month and vary in intensity.

It’s not always straightforward to determine whether your symptoms are related to PMS or menopause. Both phases involve hormonal fluctuations, which can make it confusing — especially if your body starts reacting differently than it used to.

Do you recognise one or more of these symptoms?

• Irritability and mood swings
• Fatigue and low energy
• Tender breasts
• Sleep disturbances
• Increased cravings for sweet or salty foods
• Feelings of anxiety or depression
• Brain fog (difficulty focusing or thinking clearly)

If so, it’s important to examine the pattern and context in which these symptoms occur.

What many women don’t realise: both PMS and menopause symptoms are caused by an imbalance between oestrogen and progesterone. However, with PMS, this imbalance is temporary, while during menopause, it becomes structural and progressive.

That’s why it’s important to consider not just the type of symptoms but also the pattern in which they occur.

• Timing of Symptoms
  PMS symptoms only occur during the second half of your cycle. Menopause symptoms can be present throughout the month.
• Menstrual Pattern
  With PMS, your menstrual cycle usually remains regular. During menopause, your cycle becomes irregular: shorter or longer cycles, or sometimes missed periods.
• Specific Symptoms
  Hot flushes, night sweats, and vaginal dryness are typical menopause symptoms — these usually don’t occur with PMS.
• Hormone Levels
  With PMS, your hormone levels are typically normal. During menopause, FSH levels may be elevated, which can be measured with a blood test.
• Symptom Progression
  PMS symptoms often disappear after your period. Menopause symptoms can persist, even after menopause.
• Sensitivity to Stress
  During menopause, your sensitivity to stress often increases, whereas it usually remains stable with PMS.

Duration of SymptomsPMS does not increase the risk of long-term symptoms. During menopause, some symptoms — such as sleep disturbances or mood swings — can last longer.

Women who previously experienced PMS are more likely to have intense menopause symptoms. It appears that hormonal sensitivity plays a role — your brain reacts more strongly to fluctuations in oestrogen and progesterone.

Have you noticed that:

• Your emotions are more erratic than usual?
• Your cycle has become more unpredictable?
• You’re suddenly experiencing hot flushes, night sweats, or dryness?
• You’re less able to handle stress?
• Symptoms that were once temporary now last longer?

If so, it could mean that your PMS is transitioning into perimenopause. Especially if you’re in your 40s or older, this is the time to pay attention to your body’s signals. It’s not your imagination — your body is letting you know that something is changing. You may be entering a new hormonal phase of life.

Find Recognition and Support
More and more women are sharing their experiences about this transitional phase. Read, listen, and talk — it helps to know you’re not alone. In our blogs, you’ll find relatable stories and reliable information to support you on your journey.

Keep a Symptom Diary
Record your symptoms, when they occur, and how long they last. This can help you (and your doctor or healthcare provider) determine whether your symptoms are hormonally driven and whether a pattern is changing.

Get Your Hormones Tested
A blood test can provide insight into your FSH levels — a hormone that rises as you approach menopause. Note: a single test is just a snapshot. Multiple measurements provide a more reliable picture of your hormonal phase. Want an easy way to get an initial impression? Consider the online menopause test, which gives you simple insights into your hormonal phase. You can also opt for the Silex self-test, which allows you to measure your FSH levels at home. It includes two tests for a more reliable result.

Explore Your Options
Lifestyle changes, nutrition, supplements, and possibly hormone therapy can provide support. What works for one person may not work for another — it’s all about your unique body and situation.

Reduce Stress and Support Your Nervous System
During menopause, your body reacts more strongly to stress.

Rest, breathing exercises, physical activity, and sleep are essential to regain your balance.

Whether you notice that PMS symptoms are becoming more intense or suspect that menopause has begun, your instincts are often right. You know when something is changing in your body — even if those around you don’t immediately see it. Trust your intuition, seek support, and stay curious about what you need.
