Menopause symptoms are caused by a gradual or sudden loss of the female hormone, estrogen. For this reason, the onset of menopause symptoms may be gradual or sudden, depending on the individual. Symptoms can also vary greatly in type and severity. The most common symptoms by far are ‘hot flushes’ and sweating attacks. These episodes can happen at any time, as often as several times an hour. If you can safely replace the estrogen your body no longer produces with a natural alternative, such as Hot Flash Freedom, you can avoid things like hot flashes and night sweats. Although there are some prescription drugs that show some promise in alleviating menopausal hot flashes, they also bring on many dangerous side effects and therefore should be avoided.
