Note: This is a summary of a clinical guidance document (not a single research study). It brings together evidence, clinical expertise, and national guidance (e.g. National Institute for Health and Care Excellence (NICE), Office for National Statistics (ONS), World Health Organization (WHO)).

Key message
Long COVID and menopause share many symptoms, making it difficult to distinguish between them. Care should consider both conditions and be individualised
Why this matters
- Around 1 in 20 people in the UK are living with Long COVID (ONS, 2024)
- Women aged 40–54 (perimenopause/menopause) are at highest risk (ONS, 2024; Dimpy et al., 2025)
- Symptoms from both conditions can look very similar
This means symptoms may be:
- Misattributed
- Under-recognised
- Not fully treated
What was the aim of the guidance?
This guidance brings together current evidence, clinical expertise, and existing guidance frameworks to highlight key points:
- Many symptoms overlap between Long COVID and menopause
- People may experience Long COVID and menopause at the same time
- Symptoms may fluctuate over time and with physiological changes
- Diagnosis is often complex and may require careful clinical assessment
Who does this apply to?
Women, particularly those aged 35–64
Those with:
- Long COVID
- Perimenopause
- Menopause
What symptoms overlap?
| LONG COVID | MENOPAUSE |
|---|---|
| Fatigue | Fatigue |
| Brain fog | Brain fog |
| Anxiety | Low mood/anxiety |
| Sleep problems | Insomnia |
| Feeling hot/cold | Hot flushes/night sweats |
| Breathlessness | Palpitations |
| Muscle aches | Joint pain |
| Headaches | Headaches/migraines |
| Sexual dysfunction | Loss of libido |
(Adapted from Table1: Common symptom)
Key Point: Many symptoms overlap, making it difficult to identify the underlying cause through clinical assessment alone.
Key findings
1. Women are disproportionately affected
- Epidemiological data indicate higher prevalence of Long COVID in women
- Peak risk overlaps with menopause age
2. Symptoms are difficult to separate
- Fatigue, brain fog, and sleep issues occur in both
- Patients may experience both conditions at the same time
3. Symptoms may fluctuate over time and with activity or physiological changes
- Symptoms can:
- Worsen with activity
- Change across the menstrual cycle, suggesting possible physiological or hormonal influences
- Relapse over time
4. Diagnosis is clinically challenging
- Long COVID is often a diagnosis of exclusion, based on clinical assessment and symptom pattern over time
- Menopause should always be considered during assessment
- Symptoms such as fatigue and cognitive dysfunction (“brain fog”) are non-specific and may have multiple causes
5. Care requires a holistic approach
- No single treatment approach
- Requires:
- Physical care
- Psychological support
- Occupational support
How should this be interpreted?
This is a clinical guidance document rather than a single research study. It brings together observational evidence, clinical expertise, and national guidance to support understanding and management. The evidence base is still evolving, and some recommendations are based on clinical judgement where evidence is limited.
What this means
For individuals
- Symptoms such as fatigue, brain fog, and poor sleep may have more than one contributing cause
- Long COVID and menopause may occur at the same time
For healthcare
- Assessment may need to consider both Long COVID and menopause
- Symptoms are often non-specific and may require careful clinical evaluation over time
For work and daily life
- Symptoms may affect ability to work
- Some people may require workplace adjustments
Management and support
The guidance highlights that management may require a combination of approaches, including physical, psychological, and occupational support. It emphasises that care is typically individualised rather than based on a single intervention.
Key idea: No single intervention is sufficient – care should be individualised and integrated
Limitations
- Not a controlled research study
- Evidence is derived from a combination of observational data, clinical expertise, and consensus guidance
- Evidence base is still developing
- Many recommendations rely on a combination of:
- Clinical experience and observational/real-world evidence
- Cannot establish cause-and-effect relationships
- Guidance is based partly on expert consensus where evidence is limited
Summary
Long COVID and menopause can present with similar symptoms, making assessment and management more complex. Recognising this overlap may help improve understanding of symptom patterns and support more personalised care.
Key consideration
Symptoms such as fatigue, poor sleep, and cognitive changes may have more than one contributing cause. Both Long COVID and menopause should be considered during clinical assessment.
