Hot flushes are the most common symptom of the menopause and not all women will experience hot flushes going through the menopause, but most do. Three out of every four menopausal women have hot flushes. They’re characterised by a sudden feeling of heat which seems to come from nowhere and spreads through your body. They can include sweating, palpitations, and a red flush (blushing), which vary in severity from woman to woman.
