About 75% of women experience hot flushes, making them one of the most common symptoms of menopause. But if you've not even hit perimenopause yet or you're already postmenopausal, it's still possible to experience a hot flash, as there are other causes.
However, in all cases, visit your doctor before you do anything else. There are some simple explanations for a hot flush (for some, all it takes is alcohol or eating spicy food), but some are more serious and may need urgent intervention.
