Hot Flushes in Menopause: Symptoms, Causes, and Treatments
at Omniya Clinic in London
Hot flushes (also called hot flashes) are among the most common symptoms of perimenopause and menopause. They can be brief and occasional or intense and frequent, sometimes disrupting sleep, work, and confidence.
You’re not alone: most women experience vasomotor symptoms such as hot flushes and night sweats during the menopausal transition, according to the British Menopause Society. These temperature surges are often linked to hormonal changes that affect the body’s internal thermostat.
At Omniya Clinic in Knightsbridge, we take a medical, root-cause approach to managing hot flushes. Our doctors assess hormone balance, thyroid and metabolic health, sleep, stress, and lifestyle factors, then build a plan that fits your needs, whether that involves HRT, a non-hormonal treatment, or a holistic programme to calm symptoms and restore your wellbeing.
What Are Hot Flushes?
Hot flushes (also called hot flashes) are sudden waves of heat that spread through the chest, neck, and face. Your skin may flush, you might start sweating, feel your heart race, or even experience a chill once it passes.
These temperature surges occur when falling oestrogen levels during perimenopause and menopause affect the hypothalamus – the part of the brain that regulates body temperature. When the brain misreads your body as overheating, it triggers the blood vessels to widen, releasing heat suddenly.
While hot flushes are most common during menopause, they can also be influenced by:
For many women, these episodes can range from mild and occasional to frequent and disruptive, particularly at night. Understanding your triggers and hormonal profile is the first step toward effective, lasting relief.
Symptoms of Hot Flushes
Hot flushes are sudden sensations of intense heat, often starting in the face, neck, or chest. Your skin may become warm or red, and you may begin to sweat – sometimes followed by a chill once the flush passes. These episodes can occur at any time of day but are especially common at night, leading to what’s known as night sweats.
Common symptoms of hot flushes include:
If your hot flushes are frequent, severe, or affecting your sleep or daily comfort, it’s a good idea to speak with a clinician. At Omniya Clinc, our team can help identify what’s driving your symptoms and create a tailored plan to bring your body, and confidence, back into balance.
Causes of Hot Flushes
Hot flushes are most commonly caused by declining and fluctuating oestrogen levels during perimenopause and menopause. These hormonal shifts affect the hypothalamus – the part of the brain that controls body temperature – making it more sensitive to small changes in heat.
When oestrogen levels fall, the brain’s "thermostat" misfires and triggers blood vessels to widen (vasodilation) to release heat. This leads to the sudden sensation of warmth, redness, and sweating that characterise a hot flush.
Other contributing factors can make these episodes more frequent or intense, including:
While hot flushes are closely linked to menopause, they can continue for several years after periods stop, especially without hormonal or lifestyle support. The good news is that with the right medical assessment and tailored care, these symptoms can be effectively managed.
What Treatments Are Available For Hot Flushes?
Experts estimate that up to 80% of women going through menopause experience hot flushes, which can vary in intensity and frequency, potentially disrupting sleep and daily activities. If this is the case for you, we recommend the following treatments at Omniya to ease your symptoms.
How to Ease Hot Flushes at Home
Hot flushes can be uncomfortable, but there are many ways to reduce their intensity and frequency. Simple changes to your lifestyle, combined with medical support where needed, can make a significant difference.
If self-care alone isn’t enough, Omniya Clinic in Knightsbridge offers medical and holistic options to help you manage hot flushes more effectively – from HRT to nutritional and lifestyle support tailored to you.
Hot Flushes After Menopause
For some women, hot flushes don’t stop when menopause ends. These postmenopausal hot flushes can continue for several years, and in a small percentage of women, they may persist long-term. This happens because oestrogen levels remain low and the brain’s temperature control centre stays hypersensitive, even after periods have stopped.
The approach to managing hot flushes after menopause is similar to that during the transition:
Your clinician will help you weigh the benefits, risks, and personal preferences of each approach to find the best path forward. The goal is always the same – to reduce symptom intensity, improve sleep and comfort, and help you feel like yourself again.
Treatments Available at Omniya Clinic
At Omniya Clinic in Knightsbridge, we recognise that no two women experience menopause in the same way. Your practitioner will take time to understand your unique symptoms, health history, and goals before creating a tailored plan to manage and reduce hot flushes effectively.
Your treatment journey typically includes:
Consultation → Targeted tests (only if useful) → Tailored plan (HRT and/or non-hormonal therapy + Lifestyle guidance) → Review and optimisation.
Our Goal
To restore comfort, balance, and confidence by addressing the underlying causes of your hot flushes, not just the symptoms.
Hot Flushes in Men
Although hot flushes are more common in women, men can experience them too – most often due to low testosterone levels or hormonal treatment for prostate cancer. When testosterone drops, the brain’s temperature control centre becomes more sensitive, causing sudden feelings of heat, sweating, and flushing similar to menopausal symptoms.
A gradual decline in testosterone, sometimes called andropause or the "male menopause," can also trigger hot flushes, low libido, fatigue, and mood changes. These changes tend to occur gradually with age but can become more noticeable after illness, stress, or weight gain.
Men experiencing persistent or distressing hot flushes should seek a comprehensive health and hormone assessment. At Omniya Clinic, our doctors provide Testosterone Replacement Therapy (TRT) where clinically appropriate, helping to restore hormone balance, energy, and confidence.
Hot Flushes FAQs
Hot flushes typically last from 6 months to 2 years for most women, but it’s not unusual for them to persist much longer, sometimes up to 10 years, especially if they start early. A small number of women may experience them indefinitely. Additionally, it’s possible for hot flushes to recur more than 10 years after menopause, continuing into The Real Age Test 70s and beyond. Unfortunately, there’s no certain way to predict their onset or duration.
If you start experiencing hot flushes, it’s important to stay hydrated, dress in layers, avoid triggers like spicy foods and caffeine, and practice stress-reduction techniques like deep breathing or meditation. If they significantly impact your quality of life, book in a consultation at Omniya Clinic for further evaluation and management options.
Hot flushes commonly occur during perimenopause and menopause, typically between the ages of 45 and 55, but can also occur earlier or later depending on individual factors.
Yes, hot flushes can be managed with various treatments. Hormone replacement therapy (HRT) is the most effective, but other options include lifestyle changes, non-hormonal medications, and alternative therapies like acupuncture.
While hot flushes themselves are not harmful, frequent and severe episodes can affect quality of life and may be associated with other health issues such as sleep disturbances, anxiety, and cardiovascular concerns. It is important to discuss symptoms with your healthcare provider or practitioner at Omniya Clinic.
Supplements that may help manage hot flushes include Evening primrose oil, vitamin E, black cohosh, and phytoestrogens like soy isoflavones. However, it’s crucial to discuss with a healthcare provider before starting any supplements as they can interact with medications and may not be suitable for everyone.
Yes, some women may experience a recurrence of hot flushes even years after the menopause transition. These late-onset hot flushes can occur well into the 70s or beyond.
The best treatment for hot flushes varies depending on individual health, severity of symptoms, and personal preferences. Hormone replacement therapy (HRT) is highly effective for many, while others might prefer non-hormonal medications or lifestyle adjustments.
Hot flushes are typically characterised by sudden warmth, redness of the face and neck, sweating, and sometimes palpitations. If you are experiencing these symptoms along with irregular periods, it’s likely related to menopause. However, other medical conditions can also cause similar symptoms, so consulting a healthcare provider for an accurate diagnosis is recommended.
There isn’t a specific number that is considered "too many" hot flushes. However, if hot flushes are frequent enough to interfere with your daily life or sleep patterns, it’s a good idea to consult a healthcare provider for management strategies.
During a hot flush, you might feel like your temperature is rising, but the actual increase in core body temperature is usually very slight. The sensation of heat is more about increased blood flow to the skin and sweating.
The frequency of hot flushes varies widely. Some may experience a few a week, while others might have several per day. If the frequency disrupts your daily life or sleep, seeking medical advice is advised.
It’s most common to start experiencing hot flushes during perimenopause, typically in the mid to late 40s, but they can start earlier or later depending on individual hormonal changes.
Signs of low oestrogen may include hot flushes, night sweats, vaginal dryness, mood swings, and decreased libido. Blood tests can confirm low oestrogen levels, so discussing symptoms with a healthcare provider is advisable.
Hot flushes are most common during perimenopause (the stage leading up to menopause) and may continue through menopause and postmenopause. They are one of the hallmark symptoms indicating the transition into menopause.
