Hitzewallungen: Eine plötzliche Welle milder oder intensiver Körperwärme, die durch Hormonveränderungen verursacht wird, die sich aus verminderten Östrogenspiegeln ergeben. Hitzewallungen kann jederzeit auftreten und kann von wenigen Sekunden bis zu einer halben Stunde dauern. Sie sind auf das Öffnen und die Einschränkung des Blutgefäßes und das Symptom der Wechseljahre zurückzuführen.

Hitzewallungen 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. They decrease in frequency over time. The cause of hot flashes is not completely understood. Hitzewallungen may have more to do with fluctuation of hormone levels as opposed to low hormone levels per se.

Hitzewallungen can be treated with either oral (by mouth) or transdermal (patch) forms of estrogen. Both oral and transdermal estrogen therapies are available either as estrogen alone or as estrogen combined with progesterone . All available prescription estrogen replacement therapies whether oral or transdermal are effective in reducing hot flash frequency and severity. Generally available treatments decrease hot flash frequency by about 80-90%.
