Menopausal women troubled by hot flashes

The principle cause of hot flashes is vasomotor instability, it is important to understand what external causes may also precipitate them. If aware of the conditions under which you are most likely to experience hot flushing. In many women alcohol, coffee, soft drinks, and spicy foods trigger hot flashes.

For some women hot flushing may include the sensation of skin "crawling," dizziness, heart palpitations, or faintness. These uncomfortable sensations are not experienced by everyone; some women only experience the feeling of enveloping heat which soon goes away and which they find quite tolerable. For others, this symptom can be quite embarrassing or even debilitating. Flushing can last anywhere from several seconds to ten minutes or more.

Hot flashes are due to motor instability. The most common theory is that the body's thermostat in the hypothalamus is undergoing great hormonal fluctuations. Although the pituitary hormones we spoke about earlier, FSH and LH, are still produced at regular intervals, the ovaries no longer respond. Poor diet and stress are closely linked to the onset of hot flashes, although the ovary is the prime culprit in causing them. It has also been postulated that the unnatural estrogenic substances caused by the pollutants in our environment, called xeno-estrogens, may be precipitating "ovarian dysfunction, a circumstance not anticipated by Mother Nature." This is perhaps why women in industrialized countries experience hot flashes so much more than women in third world countries.

Menopausal women are troubled by hot flashes for a period of five years or more. Some women experience them for 10 to 20 years, although their intensity and duration generally diminish with time. Only a small percentage of women have hot flashes for more than twelve years. This symptom, like other menopausal symptoms, can be predicted in part by examining how they affected our mothers. They are also usually more severe in women that do not sweat easily, who are very thin, or who experience surgical menopause.
