Women’s Health Clinic FAQ
What causes hot flushes and why do they happen?
Hot flushes and night sweats can be physically disruptive, embarrassing and exhausting, so the explanation should go beyond saying they are common.
Direct answer
Hot flushes are vasomotor symptoms linked to changing oestrogen signalling and a narrower temperature-control range in the brain. Small body temperature shifts can trigger heat, flushing, sweating, chills or palpitations. Clinical context matters because age, bleeding pattern, symptom timing, contraception, medicines and medical history can change the safest interpretation. Seek review if symptoms are severe, unusual, persistent or difficult to explain. This keeps the answer practical without turning normal variation into false reassurance.
A strong answer explains the brain temperature-control mechanism, the body response and when sweating or sleep disruption may need review.

Detailed answer
Detailed answer
The deeper answer starts by matching the symptom or definition to the right phase of menopause, tissue change or pelvic-health pathway.
Thermoregulatory narrowing
The reader wants a mechanism: why heat, sweating, palpitations and flushing happen.
Pattern
Assessment
Support
Thermoregulatory narrowing
This is the first distinction because it shapes whether the answer is about definition, ovarian signalling, tissue health, bladder symptoms or pelvic support.
Oestrogen signalling
Symptoms should be interpreted alongside age, timing, cycle pattern, severity, medical history and whether the change is new or worsening.
Body response during a flush
Management should be discussed as a set of options rather than one automatic route, especially where hormones, bleeding, urinary symptoms or pelvic pain are involved.
Common triggers
Follow-up matters when symptoms persist, affect sleep, sex, bladder function or daily life, or when the diagnosis is uncertain.
How the research shapes the answer
Comparative Efficacy: While systemic HRT remains the more likely to be useful overall option for relieving VMS, fezolinetant ranks among the more likely to be useful non-hormonal pharmacological options available to patients. Systemic Limitations: Because neurokinin antagonists are highly targeted and do not raise systemic oestrogen levels, they.
The benchmark was used for search intent and structure, but final wording was kept cautious, UK-facing and clinically useful.
Patient safety
Why this matters
Menopause can affect comfort, sleep, bleeding patterns, sexual health, urinary symptoms, confidence and long-term health, but not every symptom has the same cause.
It avoids missed causes
Symptoms that sound menopausal can also involve thyroid disease, pregnancy, infection, skin conditions, medication effects, prolapse or abnormal bleeding.
It validates symptoms
Being common does not make a symptom trivial; sleep loss, dryness, urgency or unpredictable bleeding can affect daily life and relationships.
It guides treatment choice
The right plan may involve reassurance, lifestyle support, pelvic-health care, non-hormonal options, hormone discussion, investigation or referral.
It keeps safety visible
Bleeding after menopause, severe pain, recurrent infection symptoms or rapid change should be checked rather than folded into a general menopause label.
Calm, individualised care
A strong answer should make the biology understandable without turning normal variation into fear.
It should also show when symptoms deserve help, because many menopause concerns are manageable once the cause is clear.
Considerations
What to consider
Dosing: Fezolinetant is administered as a 45 mg tablet taken orally once a day, and it can be taken with or without food. Missed Doses: If a dose is missed, it should be taken when remembered unless there are fewer than 12.
Consultation priorities
The consultation should clarify symptoms, age, period history, contraception, medical history, medicines, personal priorities and any red flags.
Pattern
Options
Follow-up
Before deciding
Check whether the question is about normal transition, early menopause, GSM, urinary symptoms, pelvic-floor change or bleeding that needs assessment.
Testing boundaries
Blood tests are not always useful in typical menopause after 45, but younger age, POI concern or unclear symptoms may need a different approach.
Treatment discussion
Treatment choices should be matched to symptoms, health background, personal preference, contraindications and realistic goals.
If symptoms change
New bleeding, pelvic pain, recurrent urinary symptoms, breast changes, weight loss, fever or unexplained night sweats should be reviewed.
What not to assume
Do not assume every change after 40 is menopause or that every menopause symptom has to be tolerated.
Timelines vary: some menopause symptoms fluctuate for years, while GSM and pelvic symptoms may persist unless the underlying tissue or bladder factors are addressed.
Common concerns and myths
Common misconceptions
Online menopause advice can be either dismissive or overconfident. These corrections keep the answer balanced.
Myth: Hot flushes are just anxiety
Reality: the clinical picture depends on age, symptom pattern, history and whether there are features that need review.
Myth: Everyone has the same trigger
Reality: the clinical picture depends on age, symptom pattern, history and whether there are features that need review.
Myth: Flushes are always mild
Reality: the clinical picture depends on age, symptom pattern, history and whether there are features that need review.
Common does not mean simple
Menopause can explain many patterns, but diagnosis still depends on context, age, bleeding history and symptom detail.
Support should be proportionate
Some symptoms need reassurance and practical advice; others need examination, testing, treatment discussion or referral.
Safety checklist
Safety checklist
Use these checks to decide whether symptoms can be discussed routinely or need more urgent advice.
Is the pattern expected?
Mild, fluctuating symptoms around the transition are different from severe, persistent, one-sided or rapidly worsening symptoms.
Is there unusual bleeding?
Postmenopausal bleeding, bleeding after sex, very heavy bleeding or bleeding with pain should be assessed.
Are bladder or pelvic symptoms present?
Urgency, recurrent UTI symptoms, leakage, pelvic pressure or pain may need urine testing, examination or pelvic-health review.
Is daily life affected?
Sleep loss, painful sex, dryness, mood change, flushes or fatigue are worth discussing when they affect wellbeing.
More reassuring signs
Symptoms are more reassuring when they are mild, improving, already assessed, and not linked with bleeding, fever, severe pain or unexplained weight loss.

Postmenopausal or unusual bleeding
Bleeding after menopause, bleeding after sex, very heavy bleeding or bleeding with pelvic pain should be assessed promptly.
Severe pain or rapid worsening
Sudden pelvic pain, severe vulval pain, urinary retention or rapidly worsening symptoms need medical advice.
Infection or systemic symptoms
Fever, flank pain, blood in urine, foul discharge, feeling very unwell or recurrent UTI symptoms should be checked.
Emergency symptoms
