Causes of Hot Flashes

Learning about the causes of hot flashes provides the key to understanding how to prevent and treat these troublesome attacks. While the exact causes of hot flashes are complex and not completely understood, most doctors and researchers believe hormonal changes are the primary cause of hot flashes. In addition to these completely normal hormonal causes of hot flashes, other medical conditions can, in more rare instances, cause hot flashes.

Hot Flashes	Hormonal Causes of Hot Flashes The most common cause of hot flashes in menopausal women is changing levels of estrogen in the body. During the time leading up to menopause, most women will experience fluctuations in their hormonal levels, particularly decreased levels of estrogen. Diminished amounts of estrogen have a direct effect on the hypothalamus, the part of the brain responsible for controlling appetite, sex hormones, sleep, and body temperature. Although the exact reason remains unknown, lowered levels of estrogen confuse the hypothalamus, causing it to inappropriately sense that the body is overheating. The hypothalamus leaps into action, sending messages to the body to go into "cool down" mode, leading to flushing, sweating and the other components of the chain of reactions that women experience as "hot flashes".

The Estrogen Withdrawal Theory

Some experts believe that estrogen withdrawal is the primary culprit in hormonal causes of hot flashes. Under this theory, the withdrawal of estrogen causes the hypothalamus to produce more norepinephrine and serotonin.

These neurotransmitters are responsible for setting the point at which heat loss mechanisms are activated in the body. When more of these chemicals are produced, heat loss mechanisms are more easily triggered by subtle changes in core body temperature, thus causing hot flashes.

In addition to estrogen fluctuations during menopause, other conditions can also cause hot flashes. Read on to learn more about the other causes of hot flashes during menopause, in order to gain a greater understanding of this unnerving symptom.

Other Causes of Hot Flashes

While by far the most common, hormonal changes are not the only cause of hot flashes. Certain medical conditions and medications can sometimes cause a person to experience hot flashes. For this reason, women for whom menopause is unlikely or women with other unexplained symptoms should consult a doctor to rule out these other potential causes of hot flashes.

Diseases that can cause hot flashes: • Panic disorder • Infection • Cancer • Diabetes • Hyperhidrosis • Thyroid disease • Obesity

Medications that can cause hot flashes: • Raloxifene (osteoporosis drug) • Tamoxifen (cancer drug) • Gonadotropin analogues (leuprolide,   goserelin and nafarelin)
