Causes of night sweats and hot flashes in menopause

Hot flashes and night sweats in perimenopausal and menopausal women are frequently referred to clinically as vasomotor symptoms. The vasomotor symptoms, usually referred to as hot flashes and reported by about 85 percent of menopausal women, are connected to the decline in ovarian function.

Hot flashes are the most common symptoms linked with the menopausal period and second to irregular menses during the perimenopausal period. The physiology of hot flashes, the mechanism of lowered estrogen levels and hot flashes, the average age of onset, factors, duration, frequency aren’t still understanding.

A few factors may affect the frequency and/or severity of hot flashes in some women.
Stress, hot or spicy foods, hot drinks, warm environments, alcohol, and caffeine are the most common factors. Hot flashes are sudden, transient episodes ranging from just feeling warm or overheated to intense heat and perspiration.

Women tend to describe a wavelike sensation over the body, particularly of the upper torso, face, and head. If the hot flashes occur at night and are associated with what can be drenching perspiration, they are called night sweats.

Women with surgically induced menopause often report particularly persistent, more intense, and more frequent hot flashes. It has been determined by one large study that for most women hot flashes last about 2 years, although some women experience them for 5 to 10 years.

It is interesting but not all cultures report the same incidence of hot flashes or other menopausal symptoms. For example, Japanese and Indonesian women report far fewer hot flashes than do women from Western societies.

Mayan women in the Yucatan do not report any symptoms at menopause other than menstrual cycle irregularity.

The clearest explanation for hot flashes is that they appear to be the body’s response to a sudden but transient downward resetting of the body’s thermostat, which is located in the hypothalamus.

This temporary alteration of the set point would cause the sensation of intense heat and flushing. What we don’t know is what factors this event.

A logical correlation between low estrogen levels and hot flashes exists. Estrogen levels have been found to be lower in premenopausal women with hot flashes than in those without hot flashes.

However, not all studies are consistent, and some women never have hot flashes, while others have persistent ones, and yet others have them only sporadically. Prior to puberty, girls have low estrogen levels, but not hot flashes. Also, hot flashes are reported during pregnancy, when the estrogen level is high. Some researchers believe that hot flashes are due to an imbalance in beta-endorphins and other opiates in the brain that in turn may influence the temperature regulation center.

Estrogen and progesterone may alter the activity of these naturally occurring opiates, and it is possible that lower levels of estrogen and progesterone cause a withdrawal of opioids, triggering a hot flash.

What may seem like a hot flash due to perimenopause or menopause may in rare cases be caused by another condition such as thyroid disease, epilepsy, infection, insulin-producing tumors, pheochromocytoma, carcinoid syndromes, leukemia, pancreatic tumors, autoimmune disorders, or allergic disorders.
