Women appear to be more likely than men to develop Long COVID, particularly during midlife, although the size of this difference varies between studies and populations. Researchers are investigating several possible explanations, including differences in immune responses, autoimmunity, hormones and biological sex, but there is unlikely to be one simple cause. At the same time, women with complex chronic symptoms have historically faced delays in diagnosis and are more likely to report experiences of having symptoms attributed to stress or anxiety. Long COVID therefore sits at an uncomfortable intersection: a condition that disproportionately affects women developing within a healthcare system that has not always been good at recognising complex illness in women.
Key Facts
- Women have shown a higher risk of Long COVID than men in multiple large studies, although risk varies with age and other factors.
- Biological explanations under investigation include sex differences in immune responses, autoimmunity and hormonal influences.
- Long COVID can affect menstruation, reproductive health and symptoms around perimenopause, although research remains incomplete.
- Women are disproportionately affected by several other immune-mediated and post-infectious illnesses that share features with Long COVID.
- Gender bias in medicine can influence how symptoms are interpreted, particularly when routine investigations are normal.
- Anxiety and depression can coexist with Long COVID, but psychological symptoms should not automatically be assumed to explain new physical disability.
Why Is Long COVID in Women More Common?
Long COVID in women raises an important question: why do women appear more likely to develop the condition, particularly during midlife? The answer may involve much more than one biological difference. Immunity, hormones, autoimmunity and dysautonomia may all play a role, while longstanding gaps in women’s healthcare can make an already complex illness even harder to recognise.
Many tell remarkably similar stories. They were working, exercising, raising children and managing busy lives before COVID. Months later, climbing the stairs makes their heart race, a supermarket trip can wipe out the rest of the day, and concentrating on a conversation feels unexpectedly difficult. Yet because routine blood tests, scans or cardiac investigations may come back reassuring, some encounter another explanation remarkably quickly: perhaps it’s anxiety, stress, burnout, menopause or simply the pressures of modern life.
Sometimes those things genuinely are part of the picture. But they cannot explain away a population-level observation that researchers themselves have repeatedly identified: women appear to have a greater risk of developing Long COVID than men.
That raises two very different questions. Why might women be biologically more susceptible to Long COVID?Once they become ill, are we equally good at recognising that illness? Those questions are often mixed together. They shouldn’t be.
The First Surprise: Being Female May Be Both an Advantage and a Vulnerability
Women generally mount stronger immune responses to infections and vaccines than men. In many situations, that’s useful. A more vigorous immune response can improve defence against infectious disease, and biological sex differences in immunity are well established.
But there is another side to that advantage.
Women also develop autoimmune diseases far more frequently than men. Conditions including Sjögren’s syndrome, lupus, autoimmune thyroid disease and rheumatoid arthritis disproportionately affect women. Researchers studying Long COVID have consequently become interested in whether the same highly responsive immune system that can provide stronger protection against infection might, in some people, also be more vulnerable to persistent immune activation or autoimmunity afterwards.
This doesn’t mean Long COVID is simply an autoimmune disease, nor that female hormones “cause” it. Long COVID appears to involve several overlapping biological pathways, potentially including immune dysregulation, viral persistence, vascular dysfunction, autonomic dysfunction and autoimmunity. But sex differences in immunity may help explain something patients noticed long before researchers had enough data to quantify it: Long COVID does not affect men and women in exactly the same way.
And this is where the story becomes much more interesting than “women aren’t being believed.” Because there may be two gender gaps happening at exactly the same time. One is biological. The other is medical.
When Biology and Women’s Health Start to Overlap
This is where Long COVID becomes particularly complicated for women. Several of the systems researchers are investigating in Long COVID the immune system, autonomic nervous system and hormonal system already behave differently across the female lifespan. When symptoms begin after COVID in the thirties, forties or fifties, it can therefore become surprisingly difficult to work out what is driving what.
A woman in her forties may therefore arrive at her GP with a collection of symptoms that genuinely cross several medical territories at once.Take palpitations, dizziness, poor sleep, temperature intolerance, headaches, brain fog and fatigue. These can occur with Long COVID and dysautonomia, but some can also appear during perimenopause. Menstrual changes after infection can add another layer of confusion. A woman in her forties may therefore arrive at her GP with a collection of symptoms that genuinely cross several medical territories at once.
The problem isn’t that menopause or hormones shouldn’t be considered. They absolutely should. The problem comes when they become the end of the investigation rather than one part of it. A hormonal explanation doesn’t automatically account for new post-exertional malaise, significant orthostatic intolerance or a dramatic loss of physical capacity that began after COVID.
That distinction matters
And this can become almost comical if it weren’t so exhausting. Your racing heart is blamed on anxiety, the brain fog on perimenopause, the fatigue on being a busy woman, and the poor sleep on stress. By the end of the appointment, almost every symptom has acquired its own perfectly reasonable explanation. The only problem is that nobody has explained why they all appeared after COVID, at roughly the same time, in a body that was functioning very differently before.
Sometimes the useful question isn’t simply “Are you tired?”
It’s “What happens to your body when you stand up?”
That small change in question can reveal an entirely different illness pattern.
Then There Is Autoimmunity
The female predominance of autoimmune disease offers another clue, although we’re still far from having the complete answer. Women account for the majority of people living with many autoimmune conditions, and researchers have identified autoantibodies and other signs of altered immune regulation in subsets of people with Long COVID.
This doesn’t prove that Long COVID is an autoimmune disease. Increasingly, the evidence suggests there may not be one single biological version of Long COVID at all. Autoimmunity could be important for some people, while viral persistence, vascular changes, autonomic dysfunction or other mechanisms dominate in others.
But for women who develop new autoimmune-type symptoms after COVID, the overlap deserves attention. Persistent dry eyes and mouth, Raynaud’s phenomenon, inflammatory joint symptoms, rashes or abnormal autoimmune blood tests shouldn’t automatically be absorbed into the Long COVID label without considering whether another condition might also be present.
This is particularly relevant because COVID may sometimes unmask something that was already developing. A person may have been biologically predisposed to an autoimmune condition for years without knowing it, with infection acting as one of several possible triggers that brings the disease into view.
That is very different from saying COVID causes every autoimmune disease diagnosed afterwards.
The Hormone Question Is More Complicated Than It Looks
Many women with Long COVID also report that their symptoms change around their menstrual cycle. Others describe altered periods after infection, while some women approaching menopause find themselves trying to separate new Long COVID symptoms from perimenopause. The overlap can be enormous: disrupted sleep, cognitive problems, palpitations, temperature changes, headaches and fatigue can occur in both.
This is an area where patients have arguably been asking questions faster than research has been answering them.
Do changing oestrogen and progesterone levels influence immune activity in Long COVID? Could hormonal transitions alter autonomic symptoms? Why do some women report predictable worsening at particular points in their menstrual cycle? And what role, if any, should hormone replacement therapy play when Long COVID and perimenopause coexist?
We don’t yet have sufficiently strong evidence to give simple answers to all of these questions. That’s precisely why reducing complex post-COVID illness to “it’s your hormones” is as unhelpful as ignoring hormones completely.
Both deserve investigation.
The Real Gender Gap May Be What Happens When These Things Collide
This is where the issue becomes bigger than medical bias alone. Imagine a woman in her forties who develops Long COVID, orthostatic intolerance and menstrual changes within the same period. She may genuinely be experiencing post-viral illness, autonomic dysfunction and perimenopause simultaneously.
Medicine tends to divide those problems between different specialties. The patient doesn’t have that luxury. She experiences them in one body.
She may find herself explaining the same story to a cardiologist, rheumatologist, neurologist and gynaecologist, with each specialist understandably looking at the part that belongs to them. Meanwhile, she is still the person trying to get through breakfast, remember the school form, make a medical appointment and work out whether she has enough energy left to wash her hair. The medical labels may be separate. Her life isn’t.
And perhaps that is the more useful question for clinicians to ask.
Not simply:
“Are these symptoms caused by hormones, anxiety or Long COVID?”
But: “What changed after this infection and could more than one thing now be happening?”
That question leaves room for complexity without assuming that every symptom must have a single
One of the most difficult experiences in Long COVID is being very unwell while repeatedly receiving reassuring test results. A standard blood panel may be normal. An ECG may look fine. A scan may show nothing that explains why standing in the kitchen suddenly feels like physical work.
Normal results are valuable because they can rule out other conditions and identify problems that need urgent treatment. But “we haven’t found the cause on these tests” is not the same as “nothing is wrong.” Long COVID can involve post-exertional malaise, autonomic dysfunction and other abnormalities that may not be captured by routine investigations.
For women, this can collide with an older problem in medicine. Symptoms such as fatigue, dizziness, palpitations, pain and cognitive difficulties can be attributed to anxiety, stress or hormonal changes before the full pattern has been explored. Sometimes those factors genuinely contribute, but they shouldn’t automatically close the investigation.
There is an important difference between a doctor saying, “Your heart tests are reassuring,” and saying, “Therefore your palpitations aren’t significant.” The first gives useful information. The second risks confusing the limits of a test with the absence of illness.
And for the patient sitting there thinking, “But I still can’t stand long enough to make dinner,” that distinction matters enormously.
What Better Care for Women With Long COVID Could Look Like
Better care doesn’t mean ordering every possible test or assuming every symptom is caused by Long COVID. It means starting with the person’s previous level of health, understanding what changed after infection and investigating symptoms according to the pattern they actually follow.
A woman describing exhaustion after activity, for example, should be asked what happens after exertion and whether symptoms worsen hours or a day later. Someone reporting dizziness and palpitations should be asked what happens when she stands. Menstrual changes deserve to be discussed alongside—not instead of—post-COVID symptoms, particularly when perimenopause may also be part of the picture.
It also means becoming more comfortable with the possibility that several things can be true at once. A woman can have Long COVID and perimenopause. She can have anxiety and dysautonomia. She can develop an autoimmune disease after COVID without every Long COVID symptom being caused by that autoimmune condition.
Medicine often works best when it can identify one diagnosis and one treatment. Long COVID isn’t always that cooperative.
Perhaps better care begins with a surprisingly simple question:
“What could explain the change from how this person functioned before COVID to how she functions now?”
That question shifts the focus away from whether an individual symptom looks dramatic on paper and back towards what illness has actually done to someone’s life.
The Cost of Getting This Wrong
Delayed recognition isn’t only frustrating. It can affect work, finances, relationships and family life, particularly when the person who becomes ill was previously holding several of those things together.
Many women with Long COVID are also mothers or carers. Pacing sounds relatively straightforward in a clinic, but it becomes considerably more complicated when someone needs breakfast, the school run still exists and a six-year-old has absolutely no interest in your energy envelope.
This is one of the realities that clinical descriptions of Long COVID don’t always capture. A person’s functional capacity may have fallen dramatically while the demands around her remain almost exactly where they were before she became ill.
That is why listening matters. Not because patients are always correct about the cause of every symptom, and not because clinicians should stop considering alternative explanations. It matters because the patient’s story contains information that a blood test cannot: what changed, when it changed, what makes it worse and what she can no longer do.
Those details are not secondary to diagnosis.
Sometimes they are where diagnosis begins.
Final Thoughts
Long COVID has created an unusual opportunity to look at women’s health differently. We have a new illness disproportionately affecting women arriving at the same time that medicine is being forced to confront longstanding gaps in research on female biology, autoimmune disease, hormones and complex chronic illness.
The answer isn’t to assume that every woman with Long COVID has been medically dismissed. Many receive excellent, thoughtful care. Nor should every symptom automatically be attributed to COVID when another condition may need investigation.
The lesson is more useful than that.
When a previously active woman develops a cluster of new symptoms after an infection, the fact that those symptoms cross several specialties doesn’t make them less connected. And when routine tests are reassuring, that should narrow the investigation—not end the conversation.
Women with Long COVID don’t need every symptom automatically validated as part of one disease.
They need something more fundamental: curiosity about what changed.
Frequently Asked Questions
Why are women more likely to develop Long COVID?
Studies have repeatedly found a higher risk of Long COVID among women in many age groups, although the difference varies between studies. Researchers are investigating whether stronger female immune responses, greater susceptibility to autoimmune disease, hormonal influences and other biological factors contribute. There is unlikely to be one explanation, and social factors, exposure patterns and differences in healthcare may also influence the numbers we see.
Can Long COVID symptoms be mistaken for perimenopause?
Yes, because the overlap can be substantial. Brain fog, disrupted sleep, palpitations, headaches, temperature intolerance and fatigue can occur in both Long COVID and perimenopause. However, features such as post-exertional malaise or pronounced orthostatic intolerance may point towards additional processes, which is why it can be more useful to consider whether the conditions coexist rather than trying to force every symptom into one explanation.
Why can standing be difficult for women with Long COVID even when heart tests are normal?
Some people with Long COVID develop dysautonomia or POTS, which affect how the autonomic nervous system regulates circulation and heart rate when the body is upright. Routine cardiac investigations can be reassuring because the heart itself may be structurally healthy, while the problem becomes apparent when the body has to regulate blood flow during standing. This is why the pattern and trigger of symptoms can sometimes be as informative as the symptom itself.
Does anxiety explain palpitations and dizziness in Long COVID?
Anxiety can cause palpitations, dizziness and other very physical symptoms, and it can coexist with Long COVID. But similar symptoms can also occur with dysautonomia, cardiovascular problems, endocrine conditions and other illnesses, so anxiety shouldn’t automatically be assumed to be the cause without appropriate assessment. Asking what happens with standing, exertion, meals, heat and rest can help clinicians understand the pattern more clearly.
Can hormones, Long COVID and an autoimmune condition all be happening at the same time?
Yes. These aren’t mutually exclusive explanations. Someone approaching menopause can develop Long COVID and also have an autoimmune or autonomic condition, and symptoms from each may overlap or influence one another. This is one reason a whole-person assessment is particularly important in women with complex post-COVID symptoms: sometimes the answer isn’t choosing the correct box, but recognising that there may be more than one box.

Long COVID can present differently from person to person, and symptoms such as palpitations, dizziness, fatigue, menstrual changes, cognitive problems and temperature intolerance can have many possible causes. Women experiencing new, persistent or worsening symptoms should discuss them with an appropriately qualified healthcare professional rather than assuming they are caused by Long COVID, hormones, anxiety or any other single condition.
Research into sex differences, reproductive health, hormones, dysautonomia, autoimmunity and Long COVID continues to evolve. Where evidence remains uncertain or incomplete, this article aims to reflect that uncertainty rather than present emerging theories as established fact. NICE currently recommends individualised assessment and management of people with ongoing symptoms following COVID-19.
