Beyond Hot Flushes: Surprising Symptoms of Perimenopause You Might Miss
Updated: Sep 28
When you think of perimenopause symptoms, hot flushes and night sweats probably spring to mind. And while those are certainly common, they don't give the full picture.
In reality, you can experience a wide range of unusual perimenopause symptoms. Many women find themselves dealing with experiences they don’t immediately associate with hormones, from aching joints to brain fog and sudden anxiety.
If you’ve ever wondered, “What’s happening to my body?” you’re not alone.
Let’s take a closer look at the lesser-known signs of perimenopause, what’s normal, and when it might be time to seek support.
If you’re noticing symptoms of perimenopause, an appointment with a women’s health physiotherapist for a Menopause MOT will help you better understand what’s happening in your body and give you practical, personalised ways to feel more in control.
The Difference Between Menopause and Perimenopause
Many people confuse menopause with perimenopause. They refer to their symptoms as being "menopausal" when, in fact, what they're referring to is perimenopause.
Menopause
Menopause is a single point in time rather than a phase. It's officially diagnosed when you have gone 12 consecutive months without a menstrual period. It signals the end of ovarian hormone production and reproductive function.
In simple terms, perimenopause is the transition leading up to menopause, whereas menopause itself represents the moment that transition is complete.
Perimenopause
In the perimenopausal period, your hormone levels—particularly oestrogen and progesterone—begin to fluctuate.
It typically starts in your mid-40s, although some women notice the early signs of perimenopause in their late 30s. This phase can last anywhere from a few years to more than a decade.
During this time, your body isn’t winding down in a straight line. It’s more of a hormonal rollercoaster. That’s why symptoms can feel unpredictable and often confusing.
While irregular periods and hot flushes are well-known, hormonal changes in women in their 40s can affect nearly every system in the body. And that’s where the more surprising symptoms come in.
Surprising Perimenopause Symptoms
Perimenopause can bring a range of unexpected symptoms that go far beyond the classic hot flushes and irregular periods. Some of the most surprising changes can affect how your body feels and how clearly your mind works day to day.
Joint Pain and Aches
If you’ve started waking up with stiff knees, sore hips or aching hands, you might assume it’s simply part of getting older. But perimenopause joint pain is incredibly common.
Oestrogen plays a role in reducing inflammation and supporting joint health. As the amount of this hormone in your body starts to drop, inflammation can increase, leading to discomfort and stiffness.
Many women describe it as feeling like their body has aged overnight.
Brain Fog and Memory Lapses
Forgetting why you walked into a room
Struggling to find the right word
Losing your train of thought mid-sentence
Sound familiar?
Brain fog during perimenopause can be unsettling, especially if you’re used to being sharp and organised. These cognitive changes are linked to changing hormone levels too. But they're known to be caused by poor sleep as well. And as your hormones are also affected by how well you sleep, your memory could be getting a double-whammy.
It might be reassuring to know that this is usually temporary. Your brain isn’t failing you, it’s adapting.
Still, it’s worth acknowledging how frustrating it can feel in day-to-day life.
Anxiety and Mood Changes
One of the most unexpected perimenopause symptoms is anxiety. This is particularly true if you’ve never experienced it before.
You might notice a constant sense of unease, racing thoughts or feeling overwhelmed by things that never used to bother you. Perimenopause anxiety is driven by changes to your hormones, but because of the time of life it happens, it’s often compounded by additional pressures that are natural during this time, such as career demands, ageing parents or teenage children.
Mood swings can also become more pronounced. One moment you’re fine; the next, you’re irritable or tearful without a clear reason.
Understanding that your hormones are playing havoc with your emotions can be incredibly validating. And this is a crucial step towards finding the right support.
Fatigue and Low Energy
Feeling exhausted, even after a full night’s sleep? Perimenopause fatigue is another common but often overlooked symptom.
When your hormones become unbalanced, it can disrupt your normal patterns of sleep, even if you’re not waking up with night sweats. Add to that the mental load many women carry, and it’s no surprise that your energy can plummet.
This isn’t just about feeling “a bit tired”. For some women, fatigue can significantly impact their work, relationships and overall quality of life.
Changes in Skin, Hair and Body Odour
Throughout your life, your hormones have a major influence on your skin and hair, so it’s no surprise they change during perimenopause.
You might notice:
Drier or more sensitive skin
Thinning hair
Increased hair shedding
Changes in body odour
These changes can feel particularly frustrating because they’re so visible, and often so unexpected. You might not realise that changes to your skin and hair can both start well before your periods stop.
Digestive Issues and Bloating
If your digestion suddenly feels off, perimenopause could be a contributing factor.
Hormonal fluctuations can affect gut motility and sensitivity, leading to bloating, constipation or changes in how you tolerate certain foods.
Stress also plays a role, as cortisol (the stress hormone) interacts with your digestive system. The result? You may feel uncomfortable after meals that never used to cause issues.

What’s Normal and What’s Not
With such a wide range of symptoms, it can be hard to know what’s typical and what might need further attention.
Many symptoms—like brain fog, mild joint pain, fatigue and mood changes—are normal and generally not a cause for concern. They’re part of how your body responds to hormonal shifts.
However, there are times when it’s important to look more closely. Speak to your GP if you experience:
Very heavy or prolonged bleeding
Bleeding between periods
Severe or persistent pain
Sudden or extreme mood changes
Symptoms that significantly affect your daily life
Tracking your symptoms can be incredibly helpful. Patterns often emerge over time, making it easier to identify whether you’re in perimenopause and what support you might need.
Menopause MOT
A women’s health physiotherapist can carry out a thorough evaluation to assess areas such as core strength, posture, and pelvic floor function, all of which may be affected during perimenopause and menopause.
Following this assessment, you’ll receive tailored advice on exercise and lifestyle changes, along with a personalised plan to address your individual concerns. Pelvic floor issues during this stage can contribute to symptoms like:
Discomfort during sex
Bladder leakage
Prolapse
With the right guidance and support, your perimenopause symptoms can be effectively managed, helping you feel more confident and in control of your body.
