Why perimenopause symptoms are still being missed, dismissed and misdiagnosed

A researcher at the University of Maryland recently did something no clinician had done before. She studied what women are actually saying about perimenopause on online forums, and compared it with what appears in their medical records.

The gap was striking. Women are describing cognitive and emotional symptoms being ignored, trivialised, or misdiagnosed as mental health disorders, early-onset dementia, or autoimmune conditions. Some reported months or years of unnecessary testing before anyone mentioned the word perimenopause.

Her conclusion: the symptoms women are discussing online should become the questions researchers ask next.

She is not the only one to notice. A 2025 national survey of over 1,000 women found that nearly 40% felt misdiagnosed when seeking care for perimenopause symptoms. More than half were treated for anxiety, depression, mood swings or panic attacks before perimenopause was even considered. This is not a problem of a few under-informed GPs. It is a systemic gap in how women's health is understood, taught and practised.

What women are actually saying online

On forums like Reddit, women share experiences that paint a very different picture from the one in most medical textbooks. They describe sudden mood shifts of rage and panic being labelled as psychiatric conditions rather than hormonal fluctuations, leading to antidepressant prescriptions when the root cause was never investigated. They talk about severe brain fog and memory lapses terrifying them into believing they had a degenerative cognitive disease, before anyone suggested these seemingly disconnected symptoms might be related to their hormones.

Night sweats, sleeplessness, fatigue, digestive changes, joint pain, heart palpitations, tinnitus, electric shock sensations, and a loss of confidence so profound it feels like a personality change. Women are experiencing all of these, often simultaneously, and being told it's stress, it's depression, it's their thyroid, it's their age, or it's nothing at all.

What the University of Maryland study found was that the symptoms women discuss most openly online are precisely the ones most likely to be absent from their clinical records. The conversation happening in waiting rooms and the conversation happening on forums are two entirely different things.

Why perimenopause symptoms are missed

There are several reasons this keeps happening, and most of them are structural rather than personal.

Medical training still contains minimal menopause education. A 2021 survey of UK medical schools found that the average amount of menopause teaching was just a few hours across the entire medical degree. Many GPs report feeling under-equipped to identify and manage perimenopausal symptoms. A qualitative study from the University of Bristol confirmed that GPs acknowledge gaps in their training and use variable approaches when women present with mood changes during the perimenopausal age range.

Symptoms overlap with dozens of other conditions. Anxiety, fatigue, brain fog, weight changes and joint pain can all be explained by thyroid dysfunction, depression, autoimmune conditions, or simply "getting older." Without the training to consider perimenopause as a unifying explanation, clinicians naturally investigate each symptom in isolation. This leads to fragmented care: one referral for the anxiety, another for the joint pain, a blood test for the thyroid, and nobody joining the dots.

Women themselves often don't make the connection. The Bristol study also found that many women either did not recognise perimenopause or felt inhibited and embarrassed about raising it. If you don't know that rage, panic, brain fog and digestive problems can all be hormonal, why would you mention them in the same appointment?

The "too early" problem. Perimenopause can begin in the late 30s or early 40s. Women presenting with symptoms at 38 or 42 are often told they're "too young" for menopause, which may be true for menopause but not for perimenopause. The transition can start years before periods become noticeably irregular.

The symptoms most commonly misdiagnosed

Based on the research and the experiences shared by thousands of women online, these are the perimenopause symptoms most frequently missed or attributed to other conditions.

Anxiety and panic attacks are the most commonly misdiagnosed perimenopause symptom. One in three women in the Biote survey received an anxiety diagnosis before perimenopause was considered. Oestrogen directly influences serotonin, dopamine and GABA, meaning anxiety that appears for the first time in your 40s has a strong hormonal component that is often overlooked. Our article on perimenopause and anxiety covers this in detail.

Brain fog and memory problems are among the most frightening symptoms because women often fear they are developing dementia. In reality, perimenopausal brain fog is driven by oestrogen fluctuations affecting neurotransmitter production and blood flow to the brain. It is temporary, and for most women it improves as the hormonal transition stabilises.

Fatigue and exhaustion are routinely attributed to depression, thyroid issues, anaemia or burnout. During perimenopause, fatigue can be compounded by poor sleep, hormonal fluctuations, and the sheer cognitive and emotional load of experiencing multiple symptoms at once.

Joint pain and stiffness can lead to investigations for rheumatoid arthritis or other autoimmune conditions. Oestrogen has anti-inflammatory properties and helps maintain joint lubrication. As levels decline, joint pain can appear or worsen without any underlying autoimmune cause.

Digestive changes including bloating, new food sensitivities, and altered bowel habits are common during perimenopause but rarely attributed to hormonal changes. Oestrogen directly affects gut motility, the gut microbiome, and how the body processes histamine. Many women are investigated for IBS, food intolerances or coeliac disease before the hormonal connection is considered.

Heart palpitations can trigger extensive cardiac investigations when the cause is hormonal. Oestrogen helps regulate heart rhythm and the nervous system's response to adrenaline. Fluctuating levels can cause episodes of racing, fluttering or pounding that are alarming but, in most cases, harmless.

Why this matters

Misdiagnosis is not just frustrating. It has real consequences.

Women prescribed antidepressants for what is actually a hormonal mood change may not respond to treatment, because the root cause is not being addressed. The Bristol study noted that assigning perimenopause-related mood changes to primary psychiatric disorders could lead to prescription of antidepressants when hormonal support might be more appropriate and perhaps more effective.

Women investigated for autoimmune conditions, cardiac problems or cognitive decline undergo unnecessary testing, with all the anxiety that comes with it. Months or years pass before anyone connects the symptoms to the hormonal transition that was happening all along.

And perhaps most importantly, women lose trust in their own bodies. When you are repeatedly told nothing is wrong, or that your symptoms are "just stress," you begin to doubt yourself. The loss of confidence that many women describe during perimenopause is compounded by a healthcare experience that makes them feel unheard.

How to advocate for yourself at the GP

Track everything first. Before your appointment, track your symptoms and menstrual cycle for two to three months. Apps like Flo, Clue or Balance work well, or a notebook is fine. Note what you're experiencing, when it happens, how intense it is, and whether it follows a pattern linked to your cycle. This gives your GP a clear picture rather than a list of disconnected complaints.

Present the full picture. Don't go in to discuss one symptom. List all of them, even the ones you think are unrelated. The combination of anxiety, sleep disruption, brain fog, joint pain and digestive changes appearing together in a woman in her 40s is a strong indicator of perimenopause. Presented individually, each one gets investigated separately. Presented together, the pattern becomes clear.

Ask directly. "Could these symptoms be related to perimenopause?" is a question that changes the direction of the appointment. You are not diagnosing yourself. You are asking your GP to consider something that the data shows is routinely overlooked.

Know your rights. For women over 45, NICE guidelines state that perimenopause should be diagnosed based on symptoms and menstrual history, not blood tests. If your GP insists on a blood test and the result comes back "normal," that does not mean your symptoms are not hormonal. Hormone levels fluctuate too dramatically during perimenopause for a single test to be reliable.

If you are not heard, ask again. You have the right to request a second opinion, ask for a referral to a menopause clinic, or find a GP with a special interest in menopause. The British Menopause Society maintains a register of accredited specialists. Our guide to recognising perimenopause can also help you prepare for the conversation.

What to do next

If you recognise yourself in any of this, start here:

• Track your symptoms for two to three months. Look for patterns linked to your cycle.
• Read our guide: Am I in perimenopause? The signs, the stages, and what to do next
• Understand the anxiety connection: Perimenopause and anxiety: why it hits differently and what actually helps
• Learn what helps: Perimenopause: where to start
• Book a GP appointment and bring your symptom tracker with you.
• Talk to other women. You will be surprised how many are going through the same thing.

The fact that you are here, reading this, looking for answers, already puts you ahead. The system may not be built to help you yet, but you can help yourself. And the more women who walk into their GP armed with the right questions, the faster this changes for everyone.
