In short
- They last far longer than most women are told. Median total duration 7.4 years, and 4.5 years after the final period.
- Two to four minutes each, heat over chest and face, sweating, sometimes palpitations, then chills and anxiety.
- Oestrogen is the most effective treatment. Nothing else comes close.
- Effective non hormonal options exist, including newer medicines developed specifically for flushes.
- Several popular remedies do not work. Supplements, soy, acupuncture and trigger avoidance are not recommended by the Menopause Society.
Condition Overview
What a flush actually is
Sudden heat over the upper chest and face that becomes generalised, lasting two to four minutes, usually with heavy sweating and sometimes palpitations, often followed by shivering and a feeling of anxiety.
Frequency ranges from one or two a day to one an hour. They are worse at night, where they are called night sweats and are a leading cause of broken sleep in midlife.
How long they really last
This is the part most women are not told, and it changes how you plan.
| Finding | Duration |
|---|---|
| Median total duration | 7.4 years |
| Median duration after the final period | 4.5 years |
| If they started before your periods became irregular | Over 11.8 years in total |
| Still having flushes at age 72 | About 9 in 100 women |
There is also real ethnic variation. Total duration averaged 10.1 years in African American women and around five years in Chinese and Hispanic women.
The practical consequence is that hormone therapy is typically used for a defined period, so many women will still have symptoms when it stops. That is planned for rather than discovered.
Making sure they are actually hormonal
Several conditions produce similar episodes and are worth excluding before treatment.
- An overactive thyroid.
- Certain medications.
- Alcohol.
- Anxiety and panic episodes.
- Rarer conditions producing flushing, which are considered where the pattern is unusual.
What works
Systemic oestrogen is the most effective treatment available. Where it is appropriate, nothing else matches it. The details and the numbers are on the hormone replacement therapy page.
Where hormones are unsuitable or unwanted, the Menopause Society supports these options.
- Cognitive behavioural therapy.
- Certain antidepressants of the SSRI and SNRI classes, which are the most effective drug alternatives to oestrogen.
- Gabapentin.
- Oxybutynin.
- Fezolinetant and elinzanetant, newer medicines developed specifically for hot flushes.
What does not work
The same society specifically does not recommend paced breathing, supplements and herbal remedies, cooling techniques, avoiding triggers, exercise, yoga, mindfulness based interventions, relaxation, soy, cannabinoids, acupuncture or clonidine.
That list is worth reading twice, because most of it is what women are advised to try first.
Why the placebo effect matters here
Placebo response in hot flush trials runs as high as 20 to 50 percent. That is why any treatment that has not been tested against placebo in a randomised trial cannot be trusted on testimonials alone, and it is why so many remedies feel like they work for a while.
When to See a Doctor
- Flushes wake you at night and you are tired, irritable or struggling to concentrate the following day.
- You are avoiding meetings, exercise or social events because of the frequency or visibility of episodes.
- Flushes started in your forties while your periods were still coming, which fits perimenopause.
- You want a clear comparison of hormonal and non hormonal treatments before deciding what to take.
- Flushes come with unexplained weight loss, a fast or irregular pulse or tremor, which suggest thyroid overactivity and need testing.
- You have drenching night sweats with fever, persistent cough or swollen glands, which require investigation for infection or other serious causes.
- You are under forty five and have developed flushes with periods stopping, which needs assessment for early menopause.
How Dr. Felix Assesses This
-
1
Characterising the episodes
Dr. Felix records frequency, duration, timing, triggers and how severe each episode is, including whether you change clothes or bedding. Severity determines which treatments are reasonable, so vague descriptions are turned into something measurable you can compare against later.
-
2
Menstrual and medical history
Your cycle pattern, other menopausal symptoms, medication including tamoxifen and antidepressants, alcohol and caffeine intake, thyroid history and any personal or family history of breast cancer, clotting or cardiovascular disease are reviewed in detail.
-
3
Examination and selective tests
Blood pressure, pulse, weight and thyroid examination are performed. Thyroid function is checked where the picture suggests it, and hormone testing is used mainly in women under forty five, since above that age the diagnosis is made clinically.
-
4
Diagnosis and plan
Dr. Felix explains the likely cause and presents the realistic options side by side, hormonal and non hormonal, with their expected benefit and their drawbacks. You choose, and leave with a written plan and a review date to judge whether it worked.

Why Early Treatment Can Matter
Treating flushes early mostly restores sleep, and that single change tends to improve mood, concentration and daily tolerance more than anything else. Women often adapt around night sweats for years without realising how much has been lost to fatigue.
Timing also affects the treatment choice itself. Hormone therapy started closer to menopause and under sixty generally carries a more favourable balance than starting long afterwards, so having the conversation sooner keeps more doors open. A consultation about HRT is where that comparison is properly made.

Sleep returns first
Night sweats usually settle within weeks, and daytime function follows quickly.
Cumulative cost of poor sleep
Months of broken nights affect mood, concentration, weight and blood pressure.

Cost & Consultation Investment
The consultation is charged as Dr. Felix's time, covering the detailed symptom assessment, examination, any indicated testing, the comparison of treatment options and the written plan you leave with. Laboratory tests are billed by the laboratory and any medicine by the pharmacy. If ongoing treatment and review follow, they are arranged as a programme or membership. Current details are on the pricing page.
Frequently Asked Questions
Longer than most women are told. Median total duration is 7.4 years, with symptoms persisting a median of 4.5 years after the final period. If they started before your cycle became irregular, total duration exceeds 11.8 years.
Eventually for most women, but around 9 in 100 are still having flushes at 72, and 8 percent continue more than 20 years past menopause. Waiting it out is a longer strategy than most people assume.
Systemic oestrogen. Nothing else matches it. Where it is appropriate for you, that is the first option discussed, with the absolute risks and benefits for your age.
There are genuine alternatives with trial evidence: cognitive behavioural therapy, certain SSRIs and SNRIs, gabapentin, oxybutynin, and newer medicines developed specifically for hot flushes.
The Menopause Society specifically does not recommend supplements and herbal remedies, soy, acupuncture or cannabinoids for hot flushes. Several supplements also interact with prescribed medication.
They are comfort measures rather than treatment, and they are among the approaches specifically not recommended as therapy. That does not mean you should be uncomfortable, it means they will not control the symptom.
Because the placebo response in hot flush trials runs as high as 20 to 50 percent. That is why treatments are judged against placebo in randomised trials rather than on testimonials.
Possibly. An overactive thyroid, certain medications, alcohol and anxiety or panic episodes all produce similar episodes. Flushing with diarrhoea, wheezing or a rash points elsewhere and needs a different assessment.
Same phenomenon, occurring at night. They are particularly common then and are a leading cause of broken sleep in midlife, which is why sleep is asked about specifically.
It does not cause them, but it makes them considerably harder to tolerate. Practical measures help with comfort, though they do not control the symptom itself.
Symptoms frequently return, and given the median duration many women are still symptomatic when hormone therapy ends. That is why the stopping plan is discussed in advance rather than improvised.
It depends on which treatment is appropriate and the follow up required, so a single figure would be misleading. You get the full cost in the consultation before anything is prescribed.
