What are hot flashes?
Hot flashes are sudden sensations of flushing and heat that
some women feel when they are going through menopause. They
are one of the most common and earliest signs of menopause.
How do they occur?
Hot flashes result from a decrease in the female hormone
estrogen. Their exact cause is not completely understood,
but it is believed that estrogen production affects the part
of the brain that controls the body's temperature. Blood
vessels in the face, chest, and body widen and make you feel
warmer.
Hot flashes usually appear suddenly and without any warning,
but they may be triggered by emotional stress, excitement,
anxiety, alcohol, or some foods.
What are the symptoms?
Symptoms of a hot flash include:
- redness and warmth on the skin of your face, neck,
shoulders, or upper chest
- pounding heartbeat
- sweating followed by a slight chill.
Hot flashes may last a few seconds or as long as 30 minutes.
Most last no longer than 2 or 3 minutes. Hot flashes are
most troublesome when they occur at night and interrupt your
sleep.
How are they diagnosed?
Your healthcare provider will examine you and ask about
your symptoms.
What is the treatment?
If your hot flashes are mild and infrequent, use a fan or
sip a glass of cool water or juice when a hot flash begins.
Some natural remedies may help give some relief of hot
flashes. For example, soybeans contain isoflavones, which
are similar to the hormone estrogen.
If your hot flashes are frequent and severe, and if you have
night sweats severe enough to keep you from sleeping, your
healthcare provider may suggest hormone therapy. This
treatment involves taking the 2 hormones estrogen and
progesterone if you still have your uterus. You may take
estrogen without progesterone if you no longer have your
uterus. The hormones can be prescribed as pills that you
swallow, skin patches, creams, vaginal suppositories,
vaginal rings, shots, or pellets placed under the
skin. Depending on your age, treatment with
estrogen and progestin may increase the risk for heart
disease. It may also increase your risk for stroke, breast
cancer, blood clots, some gallbladder problems, and possibly
dementia. Also, estrogen taken without progestin increases
the risk of uterine cancer if you still have your uterus.
Discuss the risks and benefits of hormone therapy with your
healthcare provider.
Other medicines your provider may prescribe are Catapres
(clonidine) or Bellergal, a medicine that contains
phenobarbital.
Talk to your provider about what might be the best treatment
for you.
How long will the hot flashes last?
Hot flashes may begin before you have stopped having your
menstrual periods. They may stop after a few months, or
they may continue for as long as 5 years or more.
How can I take care of myself?
Try to keep cool, both physically and emotionally.
- Avoid hot, spicy foods.
- Keep as cool as you can in hot weather or in warm rooms.
Wear light, cotton clothing and dress in loose layers.
Keep your house cool and use lightweight blankets at
night.
- Don't drink or eat a lot of red wine, chocolate, or aged
cheeses. These foods contain a chemical that can affect
your body's thermostat and trigger a hot flash.
- Avoid smoking, alcohol, and caffeine.
- Exercise regularly, according to your healthcare
provider's recommendation.
- Use relaxation techniques, such as breathing exercises,
to help relieve stress.
