Hot flashes are episodes that are experienced by many, but not all, women undergoing menopause. A hot flash is a feeling of warmth, sometimes associated with flushing that spreads over the body and sometimes followed by perspiration. Menstruating women in their 40's may have hot flashes, and hot flashes may last for a decade or more in some women. There is no way to predict when they will cease in a given woman, but they usually decrease in frequency over time. The cause of hot flashes is not completely understood. Hot flashes may have more to do with fluctuation of hormone levels as opposed to low hormone levels.
