- Hot flushes are a symptom of menopause in females.
- Not all females get hot flushes at menopause.

What are hot flushes?
A hot flush may be a symptom of menopause. You may have a feeling of warmth and your skin may redden (flush). Sometimes you may have sweating. When these hot flushes occur at night, they are called night sweats.
Most females have some symptoms of menopause:
- 20% have no symptoms
- about 60% have mild to moderate symptoms
- 20% have severe symptoms
About 80% of females experience hot flushes and night sweats during menopause. However, they aren’t always troublesome.
Hot flushes may occur even before menopause (before your periods stop). They can continue to occur in females over 60 years of age.
What are the symptoms of hot flushes?
During a hot flush, you may get a feeling of warmth and your skin may become red (flush). This can start in your chest and spread to your neck and face.
People may experience hot flushes differently to each other. Some people may have them only sometimes, while other people may have them more often. They may last from a few seconds to minutes.
Night sweats may wake you from your sleep. You may need to change your sheets during the night due to heavy sweating (perspiration).
What causes hot flushes?
It’s not known why females have hot flushes. However, lower levels of oestrogen may influence how your body regulates temperature.
When should I see my doctor?
If your hot flushes affect your daily activities or night-time sleep, you may want to speak to your doctor. Your doctor will talk to you about self-help methods and whether medication may be useful.
Most people find their symptoms are manageable and choose not to have treatment. Symptoms of hot flushes can resolve over time.
