Symptoms of menopause

Menopause is the name for the natural process by which the menstrual cycle (period) stops happening in a woman. Usually, the process is gradual (takes months or years) and occurs from the age of 45 to 55 years. Menopause is officially diagnosed once a woman stops having a period for 12 months continuously. A woman with menopause will notice a decrease in the number and regularity of her periods until they completely stop. In addition, she may notice a number of symptoms that occur as a result of decreased estrogen levels, such as hot flashes, changes in mood, sleep problems, vaginal dryness, changes in libido, and changes in sexual function. Certain medications exist that can decrease these symptoms.

FAQs About Hot Flash

Here are some frequently asked questions about hot flash.

How long do hot flashes last?

There is mixed data on how long hot flashes due to menopause last. Menopause has been thought to last no longer than a few years, but recent data suggests that most individuals have hot flashes for five to seven years after menopause, and as long as twenty years after or more.

What age to hot flashes start?

Hot flashes do not begin at a particular age. They begin just before or during menopause and can continue for a decade after in most women, and up to two decades after in rarer cases. The median (most common, not the average) age of menopause is 51.4 years and is defined as 12 months of amenorrhea. Nearly half of women will experience hot flashes by age 50.

What happens during a hot flash?

During a hot flash, the processes that allow the body to manage its temperature become temporarily dysfunctional. Additionally, inappropriate dilation or widening of blood vessels causes flushing, and sweating also increases significantly. These changes can chill the body temperature and cause shivering or chills at the end of a hot flash.

What causes menopause hot flashes?

Menopausal hot flashes are caused when the body begins to withdraw from estrogen. Women during menopause stop producing estrogen and as their body adapts to its absence. Normally, the body begins to sweat and the blood vessels dilate when the temperature increases by .5 degrees Celsius (or 1 degree F). During menopause, these effects occur much earlier. Estrogen tends to solve these problems.

What causes hot flushes apart from the menopause?

Hot flashes are not commonly caused by anything apart from menopause. Additionally, however, hot flashes can be caused by an excess of thyroid hormone (hyperthyroidism). When a thyroid is overly active, it can cause an increase in thyroid hormone, which tends to advance the metabolism and cause an increase in body temperature and a subjective feeling of body temperature rising.

Questions Your Doctor May Ask About Hot Flash

To diagnose this condition, your doctor would likely ask the following questions:

  • Are you feeling irritable (easily made upset)?
  • Do you have trouble sleeping?
  • When was your last menstrual period?
  • Have you been feeling more tired than usual, lethargic or fatigued despite sleeping a normal amount?
