Menopausal Hormone Therapy
What is menopausal
hormone therapy?
Menopausal hormone therapy is a treatment that
can relieve the symptoms many women have during menopause. Regular doses
of hormones are taken to replace some of the natural hormones that decrease
at menopause. The 2 main female hormones are estrogen and progesterone.
Menopause is the time when menstruation stops permanently.
It is usually a gradual process, but it can occur suddenly in some cases.
The ovaries begin to produce less hormone. The reduced amount of hormone
causes menstrual periods to become irregular. Eventually they stop completely.
Menopause can also suddenly occur when the ovaries are surgically removed.
Menopause is part of a natural aging process and
not a disease. For many women menopause is an easy change. but some women
have problems caused by the decrease in hormones, particularly by the decrease
in estrogen. These problems may be helped by treatment that replaces some
of the lost hormone.
If your uterus has been removed, you may take estrogen
alone. If you still have your uterus, taking estrogen alone increases your
risk of cancer of the uterus. Your provider will recommend taking progesterone
with estrogen to reduce this risk.
Hormone replacement therapy (HRT) may be taken
as:
- tablets to be swallowed
- patches or lotion to be put on the skin
- a vaginal ring
- a cream to be put into the vagina
- pellets placed under the skin
- shots.
When is it used?
You may never have symptoms of menopause. or they
may occur for a few weeks, for a few months, or sometimes over several
years. Your symptoms may come and go, or they may occur regularly. Your
health care provider might recommend hormone therapy to relieve the following
symptoms, especially if they are very severe:
- hot flashes
- night sweats
- vaginal dryness, which can cause discomfort
or pain during sexual intercourse.
Until recently hormone therapy has been used to
help prevent loss of bone density (osteoporosis). However, the routine
use of HRT to prevent osteoporosis is no longer recommended. There are
other, safer treatments for osteoporosis.
Sometimes hormones may be recommended for women
who go through menopause early (before the age of 40). Removal of the ovaries
causes a sudden decrease in hormones and early menopause.
You and your health care provider should discuss
the risks and benefits of HRT for you. Factors such as your age, race,
family history, and health history must be considered. Hormone therapy
can help some of the symptoms of menopause, but it can increase the risk
for heart disease or stroke. It can also increase the risk of breast cancer
and blood clots.
What are the benefits of hormone therapy?
- Relief of menopausal symptoms, such as
hot flashes and vaginal dryness
- Prevention and treatment of osteoporosis
Osteoporosis is a disease that thins and weakens
bones. This makes it easier for the bones to break. Bone loss begins around
age 35. You start losing bone more quickly at menopause. Hormone therapy
can slow down bone loss if it is begun soon after menopause. However, your
provider may prescribe other medicines to help prevent osteoporosis. Weight-bearing
exercise, such as walking, and calcium supplements with vitamin D can also
help to reduce bone loss.
What are the risks of hormone therapy?
The risks of hormone therapy include:
- Uterine cancer: Estrogen taken without
progesterone increases the risk of cancer of the uterus. To lessen this
risk, health care providers prescribe estrogen combined with progesterone
if you have not had your uterus removed.
- Breast cancer: Estrogen taken with progesterone
(Prempro) increases the risk of breast cancer. Talk to your provider
about this risk. Many providers recommend that women be checked thoroughly
for any tumors and have a mammogram before beginning HRT. If you have
a family history of breast cancer, it is especially important to discuss
this with your provider. Estrogen taken alone appears to have no significant
effect on the risk of breast cancer.
- Cardiovascular disease, strokes, and blood
clots in the legs and lungs: Estrogen and progesterone taken together
increase the risk of heart attack, strokes, and blood clots. When estrogen
is taken alone, the risk of coronary heart disease does not seem to change,
but the risk of stroke is higher than it is in women who are not taking
HRT.
Hormone therapy may also increase your risk for
some gallbladder problems and dementia.
The risks of all forms of HRT are continuing to
be studied. The risks described above may be different for hormone therapy
that involves lower doses of estrogen and progesterone or progesterone
only. You and your health care provider should discuss the risks and benefits
of hormone therapy for you.
What are the side effects of hormone therapy?
The side effects of hormone therapy may include:
- uterine bleeding or vaginal discharge if
your uterus has not been removed
- bloating, fluid retention, and weight gain
- breast tenderness and enlargement
- nausea
- symptoms like those of premenstrual tension
(PMS), such as headaches and mood swings. when progesterone is part of
the treatment
- abnormal blood clotting.
- headache.
If your therapy includes both estrogen and progesterone, you will usually have some
vaginal bleeding if there are days in the cycle when you are not taking
hormones. Not a menstrual period, the bleeding typically lasts 2 or 3 days.
Usually you will not have any cramps with the bleeding. If you take both
estrogen and progesterone in low doses every day, the hormones will not
cause bleeding except perhaps some spotting of blood for the first 2 to
3 months.
Who should not take hormone therapy?
Hormone therapy is not recommended for women who
have any of these conditions, diseases, or medical history:
- heart attack or stroke
- uncontrolled high blood pressure
- blood clots in the legs, lungs, or eyes
- cancer of the breast or uterus
- unexplained vaginal bleeding
- liver disease.
You should not take hormones if you are or think
you may be pregnant.
Also, if you smoke, you should avoid hormone therapy.
Smoking may increase your risk of heart attack or stroke while you are
taking hormones.
If you have any of the following diseases or conditions,
you should discuss with your provider the effect of hormone therapy on
these conditions:
- uterine fibroids (These benign tumors may
grow in response to estrogen. They begin to shrink at menopause unless
you are taking estrogen.)
- endometriosis
- fibrocystic breast disease
- migraine headaches
- gallbladder disease.
What can I do to take care of myself?
If you are thinking about taking hormones:
- Talk to your health care provider about
the risks and benefits.
- Get a mammogram before you begin HRT to
check for breast cancer. Then get a mammogram every 1 to 2 years, according
to your provider's recommendation.
Ask your health care provider about:
- the different types and dosages of hormone
therapy
- any side effects or special precautions
you should know about while you are taking hormones
- when you should start and stop the taking
hormones.
If you are already taking hormones:
- Ask your provider about any special precautions
or side effects.
- If you are taking estrogen combined with
progesterone, tell your provider if bleeding occurs at any time other
than the days when you do not take the hormones.
- Be sure to have a yearly pelvic exam with
a Pap test.
- Do not change your hormone dose without
checking with your provider.
- Eat a healthy diet and exercise regularly
according to your provider's recommendations.
- Do not smoke.
- Have a mammogram every year. Examine your
breasts monthly.
- Have a complete physical exam every year.
Your blood should be tested regularly for cholesterol levels and liver
function.
