APGO educational topic 47 menopause this
00:04
is the story of Miss menopause
00:06
she has just had 12 months of amenorrhea
00:08
which by definition makes her menopausal
00:10
she is 51 years old which is the median
00:13
age of menopause in North America the
00:16
menopausal transition is a natural
00:18
transition for most women and it is
00:20
important to remember that women may
00:22
spend most of their lives in the
00:23
postmenopausal years the objectives of
00:26
this video are to define menopause and
00:28
describe associated changes in the
00:30
hypothalamic pituitary ovarian axis
00:32
describe menopausal symptoms and
00:35
physical exam findings discuss
00:37
management options for patients with
00:39
perimenopausal and menopausal symptoms
00:41
counsel patients about the menopausal
00:43
transition and finally discuss long-term
00:47
changes associated with menopause why do
00:49
women go through menopause menopause
00:51
occurs due to the program loss of
00:53
variant follicles let’s chat for a
00:55
moment about a woman’s germ cells or
00:57
sites remember that the number of germ
01:00
cells were low sites peak when she is 20
01:03
weeks in utero as 6 to 7 million by the
01:06
time she is born she has 1 million at
01:08
puberty she has 400,000 at the time of
01:11
menopause she has 2 to 300 remaining the
01:14
hypothalamus produces GnRH which
01:16
stimulates the anterior pituitary the
01:19
anterior pituitary produces FSH and LH
01:21
this stimulates the ovary to produce
01:24
estrogen with advancing age as the
01:27
number of news sites decline estrogen
01:29
levels decline the remaining sites
01:31
become increasingly resistant to FSH and
01:33
FSH plasma concentrations increase at
01:36
the time of menopause FSH levels are
01:38
greater than 30 beginning around age 40
01:41
as the number of a woman’s ovarian
01:43
follicles decrease there are changes
01:44
that occurred to her menstrual cycle she
01:47
may notice shortening or lengthening of
01:49
her cycles the luteal phase of the cycle
01:51
stays the same at 13 to 14 days the
01:54
variation at cycle length is related to
01:56
changes in the follicular phase women
01:59
may start noticing that their cycle
02:00
length is now 21 days remember that the
02:03
cycle length is from the first day of
02:04
one period to the first day of the next
02:06
period hot flashes are the most common
02:08
symptom of the menopause transition in
02:11
u.s. women the prevalence of hot flashes
02:13
of 50 to 82 percent women described the
02:16
sudden sensation of extreme heat in the
02:18
upper body particularly the face neck
02:20
and chest
02:20
these episodes typically last one to
02:22
five minutes for many women the hot
02:25
flashes are tolerable and do not require
02:26
any medical therapy 33 percent of women
02:30
who experiences hot flashes however will
02:32
experience more than 10 hot flashes a
02:33
day for some women the hot flashes are
02:38
associated with significant adverse
02:39
outcomes such as hampered job
02:41
productivity and sleep deprivation some
02:44
women can simply use lifestyle
02:45
modifications for their hot flashes
02:47
other women however are motivated to
02:49
pursue medical therapy often based on
02:51
the severity of their symptoms the most
02:53
effective treatment for hot flashes is
02:55
systemic hormone therapy on average
02:57
there’s a 75% reduction in hot flashes
03:00
both in frequency and severity if she
03:02
has a uterus the hormone therapy
03:04
needs to be both estrogen and
03:06
progesterone estrogen alone can only be
03:08
used if she does not have a uterus for
03:10
estrogen alone will increase her risk of
03:12
endometrial cancer are there risks of
03:14
hormone therapy yes the Women’s Health
03:17
Initiative was a large randomized
03:18
placebo-controlled trial this trial
03:21
demonstrated that there was an increased
03:22
risk of breast cancer
03:24
coronary heart disease stroke and Venus
03:26
from Baalak event in women taking
03:28
estrogen and progesterone verses
03:29
possible there were however decreased
03:31
risk of colon cancer and fracture and
03:33
woman taking estrogen and progesterone
03:35
for women only receiving estrogen there
03:37
was an increased risk of thromboembolic
03:39
event but not an increased risk of
03:41
cardiovascular event or breast cancer
03:43
it’s important to note that it’s
03:45
difficult to generalize the findings
03:47
from the WHI on younger more recently
03:49
menopausal women since the WHI examined
03:51
women aged 50 to 77 years old and many
03:54
were past the menopausal transition at
03:56
the time of the study what other options
03:58
are available for treatment of hot
03:59
flashes SSRIs and SNRIs are effective
04:03
treatments and they reduce hot flashes
04:05
around 50 to 62%
04:06
herbal therapies such as black cohosh or
04:09
phytoestrogens have not been shown to be
04:11
superior to placebo bioidentical
04:14
hormones are not recommended over
04:16
conventional hormone therapy for there
04:17
is limited evidence
04:19
their safety purity potency and efficacy
04:21
declining estrogen levels can induce a
04:23
change in women’s sleep cycles
04:25
independent of hot flashes and sleep
04:27
disturbances are one of the most common
04:29
and disabling effects of menopause bone
04:31
density decreases in men and women with
04:33
aging however the rate of bone loss
04:35
increases with menopause bone density
04:37
diminishes at a rate of one to two
04:39
percent per year in postmenopausal women
04:41
compared with 0.5 percent per year in
04:44
perimenopausal women the vaginal
04:46
epithelium and euro epithelium are also
04:48
all estrogen dependent tissues pelvic
04:51
organ prolapse and a trophic urethritis
04:53
can result when the pair of vaginal
04:56
tissues that support the bladder and
04:57
rectum become a trophic up to 40 percent
05:00
of menopausal women will experience one
05:01
or more symptoms of vaginal atrophy
05:04
vaginal atrophy may present with itching
05:06
and burning and the loss of vaginal
05:08
rugae and the loss of elasticity can
05:10
cause a narrowing and shortening of the
05:12
vagina vaginal atrophy and vaginal
05:15
dryness can also become symptomatic
05:16
during intercourse and can cause
05:18
significant dyspareunia vaginal
05:20
lubrication x’
05:21
vaginal moisturizers and vaginal
05:22
estrogens can all provide symptom relief
05:24
this concludes the aapko educational
05:27
video on menopause
05:28
in summary menopause is a natural
05:30
transition for most women we have
05:32
discussed the hormonal changes that
05:33
occur with menopause discuss symptoms
05:35
and physical exam findings and
05:37
management options that are available if
05:39
a woman needs it
