Perimenopause vs Long Covid Symptoms: Understanding the Overlap
Perimenopause and long covid share brain fog, fatigue, and palpitations. Learn how to distinguish them and work with doctors on both at once.
Two Conditions That Arrived Together for Many Women
The peak years of covid infection and the years when perimenopause typically begins overlap substantially. Many women aged 40 to 55 developed long covid symptoms after infection and found it almost impossible to separate those from the perimenopause symptoms they were already experiencing, or that began around the same time. The clinical challenge is real: both conditions can produce fatigue, brain fog, palpitations, sleep disruption, breathlessness, and mood changes. Doctors themselves have found it difficult to attribute symptoms clearly to one cause or the other, and many women have been caught between specialists who each focus on one condition.
Symptoms That Appear in Both
Brain fog is one of the most commonly reported symptoms of both perimenopause and long covid. In perimenopause, it relates to fluctuating estrogen and its effects on neurotransmitter function, acetylcholine, and cerebral blood flow. In long covid, it is associated with neuroinflammation, microvascular changes, and autonomic nervous system dysregulation. Fatigue in perimenopause is partly driven by disrupted sleep, hormonal shifts, and increased metabolic demand. Long covid fatigue has a different mechanism, often involving post-exertional malaise, mitochondrial dysfunction, and autonomic instability. Heart palpitations, sleep disruption, and anxiety appear in both for overlapping but distinct physiological reasons.
Features That Help Distinguish Them
Timeline and onset are the most useful distinguishing features. Perimenopause symptoms typically develop gradually over months to years and fluctuate with the menstrual cycle or in relation to stress and sleep. Long covid symptoms typically begin within weeks of a documented or suspected covid infection and may have a more constant, less fluctuating quality. Post-exertional malaise, meaning a significant worsening of all symptoms after physical or cognitive effort, is a hallmark feature of long covid that is not typical of perimenopause. If walking to the shops leaves you exhausted for two days, that pattern is more consistent with long covid or ME/CFS than with perimenopause alone.
When Both Are Happening at Once
Having both perimenopause and long covid simultaneously is not unusual, and treating one does not necessarily resolve the other. Some women report that starting HRT improved their cognitive symptoms and energy significantly, suggesting estrogen deficiency was a major contributor to their overall presentation. Others find that HRT provides modest relief but long covid symptoms persist, indicating that both need addressing separately. A small body of research has explored whether estrogen may have some protective or therapeutic role in long covid, but this is not established enough to drive clinical decisions. The practical approach is to advocate for assessment and treatment of both conditions in parallel.
Working With Doctors on Both Conditions
Getting appropriate care for both perimenopause and long covid can require persistence. Long covid clinics exist in many NHS areas and can provide multidisciplinary assessment. Perimenopause care is best sought from a GP with a menopause interest or a registered menopause specialist. Bringing a clear written summary of all symptoms, their timing relative to covid infection, and their relationship to your menstrual cycle can help each clinician understand the full picture. Asking explicitly whether hormonal assessment is relevant is worthwhile even in a long covid clinic setting, as hormonal factors are not always considered in that context.
Logging Symptoms Across Both Conditions
When two overlapping conditions are present, keeping detailed symptom records becomes especially valuable. Being able to show a doctor how symptoms fluctuate day to day, whether they worsen after exertion, and how they have changed since any treatment was started gives clinicians much better information than recall alone. Apps like PeriPlan let you log symptoms and track patterns over time. Even if some symptoms belong to long covid rather than perimenopause, having a consistent log of how you feel, your sleep quality, and your energy levels helps build the picture needed for informed care decisions. Noting whether symptoms are worse after activity is particularly useful for distinguishing post-exertional malaise from general perimenopausal fatigue, and that distinction shapes the management advice you receive significantly.
