39How Do Hormones Change with Normal Aging?
- Estrogens- decrease to very low levels over a 1-3
year period at menopause (between ages 45-55) - Testosterone (T)- Gradual decline from age 30
onward reaching low (hypogonadal) levels in gt20
of men by age 65 - Growth Hormone (GH)- Gradual decrease in
secretion (and circulating IGF-I levels) from age
45-90
40How Do Hormones Change with Normal Aging?
- Adrenal Steroids-
- Active adrenal hormones (cortisol and
aldosterone) change little - DHEA, steady decrease with age to very low levels
in both sexes - Thyroid- not much change in healthy men and
women, but increased prevalence of hypothyroid
disease in older persons. - Insulin- loss of sensitivity to insulin action
with aging and obesity

46Exercise in themenopause
- Any physical activity is better than being
sedentary - Regular exercise reduces total and cardiovascular
mortality - Better metabolic profile, balance, muscle
strength, cognition and quality of life are
observed in physically active persons. Heart
events, stroke, fractures and breast cancer are
significantly less frequent - Benefits far outweigh possible adverse
consequences the more the better, but too much
may cause harm
47Exercise in themenopause optimal exercise
prescription
- At least 30 minutes of moderate intensity
exercise, at least three times weekly - Two additional weekly training sessions of
resistance exercise may provide further benefit
48AHA 2006 Diet and Lifestyle Recommendations 1
- Balance calorie intake and physical activity to
achieve or maintain a healthy body weight - Consume a diet rich in vegetables and fruits
- Choose whole-grain, high-fiber foods
- Consume fish, especially oily fish, at least
twice a week
Circulation 200611482
49AHA 2006 Diet and Lifestyle Recommendations 2
- Limit intake of saturated fat to lt 7 of energy,
trans fat to lt 1 and cholesterol to lt 300 mg/day
by choosing lean meats and vegetable
alternatives, selecting fat-free, 1 fat and
low-fat products - Choose and prepare foods with little or no salt
- Increase fiber intake (beans, whole grain, other
fruits and vegetables) - If you consume alcohol, do so in moderation
- Quit smoking

Vorzeitige MenopauseFrauen mit vorzeitiger
Menopause sollte routinemäßig eine HRT zumindest
bis zum durchschnittlichen Menopausealter (51
Jahre) angeboten werden.
- zu überlegen ist Umstellung auf ccHRT bei
- postmenopausalen Frauen
- regulären Entzugsblutungen
- Frauen ohne irreguläre Blutungen unter scHRT
- oder
- Frauen ohne Blutung unter scHRT
Einige Frauen können eine erhöhte
mammographische Dichte entwickeln, insbesondere
unter einer höher dosierten kontinuierlich-kombini
erten HRT. Um bei solchen Patientinnen
diagnostische Probleme zu vermeiden, kann ein
Absetzen der HRT für 2-4 Wochen vor der
Mammographie in Erwägung gezogen werden.
53Zusammenfassung HRT
- Die Hormonersatztherapie sollte nur verordnet
werden, wenn eine klare Indikation besteht
(primär zur Behandlung klimakterischer
Beschwerden). - Es gibt keine wirksamen Alternativen zur
Behandlung vasomotorischer Symptome. - Die Hormonsubstitution kann bei Frauen mit
erhöhtem Frakturrisiko eine Anfangsoption zur
Senkung des Frakturrisikos darstellen. - Die langfristige Hormonsubstitution ist mit
einigen zusätzlichen Risiken verbunden. - Venöse thromboembolische Erkrankungen
- Schlaganfall
- Brustkrebs (nur bei Normalgewicht)
- Die Indikation zur Fortsetzung der
Hormonbehandlung sollte jährlich überprüft werden.
54Zu den Risiken einer HRT
- Die Indikation zur Fortsetzung der
Hormonbehandlung sollte jährlich überprüft werden - Unter besonderer Beachtung der Risiken einer HRT
55HRT Credo
- HRT bedeutet Substitution des fehlenden
körpereigenen Hormons in subphysiologischer
Dosis. - Die Evolution hat nicht eingeplant, dass die
Lebenserwartung so ansteigt - Hätten Männer einen so starken klimakterischen
Hormonabfall, gäbe es für den Mann schon lange
eine HRT. - Männer haben höhere Östrogenspiegel als nicht
behandelte postmenopausale Frauen.
56HRT Credo
- Östrogene sind nicht mutagen oder cancerogen.
- Östrogene wirken evtl. als Promotor auf
vorhandene noch okkulte Mammacarcinome.

64Alternativen zur HRT
- Kräuterextrakte können klimakterische Beschwerden
lindern ähnlich wie ein Placebo. - Phytoestrogene können die Knochenresorption
verlangsamen eine Senkung des Frakturrisikos
wurde jedoch nicht gezeigt. - a-adrenerge Agonisten (z.B. Clonidin) haben eine
moderate Wirkung auf Hitzewallungen. - hoch-dosierte Gestagene (5-10 mg NETA, 20-40 mg
MPA oder Megestrolacetat / Tag) führen zu einer
wirksamen Reduktion der Hitzewallungen. Die
Langzeit-Auswirkungen sind bisher nicht
untersucht.
65Alternativen zur HRT
- Tibolon bessert klimakterische Beschwerden und
erhält den Knochen. - Eine Senkung des Frakturrisikos konnte nicht
gezeigt werden. - Neuroaktive Medikamente (z.B. Selektive
Serotonin-Wiederaufnahmehemmer SSRIs) haben eine
moderate Wirkung auf vasomoto-rische Beschwerden.
Therapieversuch möglich, wenn eine HRT nicht
geeignet ist. - Gabapentin kann Hitzewallungen reduzieren.

77Introduction
- The following Recommendations express the views
of the IMS on the principles of hormone therapy
(HT) in the peri- and postmenopause periods - Throughout the Recommendations, the term HT will
be used to cover all therapies including
estrogens, progestogens, combined therapies and
tibolone - The 2004 IMS Statement is still valid and serves
as a basis for the current updated Recommendations
Climacteric 20071018194
78Introduction
- The IMS is aware of possible geographical
variations related to different priorities of
medical care, different prevalence of diseases,
and country-specific attitudes of the public, the
medical community and the health authorities
toward menopause management, which may all impact
on hormone therapy
Climacteric 20071018194
79Introduction
- The following recommendations, therefore, give a
global and simple overview that serves as a
common platform on issues related to the various
aspects of hormone treatment - These Recommendations were reviewed and discussed
by representatives of more than 60 national and
regional menopause societies from all continents - These Recommendations can be easily adapted and
modified according to local needs
Climacteric 20071018194
80Part I. Governing principles
IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
- Hormone therapy should be part of an overall
strategy including lifestyle recommendations
regarding diet, exercise, smoking and alcohol for
maintaining the health of postmenopausal women
Climacteric 20071018194
81Part I. Governing principles
IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
- HT must be individualized and tailored according
to symptoms and the need for prevention, as well
as personal and family history, results of
relevant investigations, the womans preferences
and expectations - The risks and benefits of HT differ for women
around the time of menopause compared to those
for older women - HT includes a wide range of hormonal products and
routes of administration, with potentially
different risks and benefits - The term class effect, when associated with HT,
is confusing and inappropriate
Climacteric 20071018194
82Part I. Governing principles
IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
- Women experiencing spontaneous or iatrogenic
menopause before the age of 45 and particularly
before 40 are at higher risk for cardiovascular
disease and osteoporosis - They will benefit from hormone replacement, which
should be given at least until the normal age of
menopause
Climacteric 20071018194
83Part I. Governing principles
IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
- Counseling should convey the benefits and risks
of HT in simple terms, e.g. absolute numbers
rather than as percentage changes from baseline
expressed as a relative risk - This allows a woman and her physician to make a
well-informed decision about HT
Climacteric 20071018194
84Part I. Governing principles
IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
- HT should not be recommended without a clear
indication for its use
Climacteric 20071018194
85Part I. Governing principles
IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
- Women taking HT should have at least an annual
consultation to include a physical examination,
update of medical history, relevant laboratory
and imaging investigations and a discussion on
lifestyle - There are no reasons to place mandatory
limitations on the length of treatment - Whether or not to continue therapy should be
decided at the discretion of the well-informed
hormone user and her health professional,
dependent upon the specific goals and an
objective estimation of benefits and risks
Climacteric 20071018194
86Part I. Governing principles
IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
- Dosage should be titrated to the lowest effective
dose - Lower doses of HT than have been used routinely
can maintain quality of life in a large
proportion of users - Long-term data on lower doses regarding fracture
risk and cardiovascular implications are still
lacking
Climacteric 20071018194
87IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part I. Governing principles
- Progestogen should be added to systemic estrogen
for all women with a uterus to prevent
endometrial hyperplasia and cancer - Natural progesterone and some progestogens have
specific beneficial effects that could justify
their use besides the expected actions on the
endometrium
Climacteric 20071018194
88IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part I. Governing principles
- Low-dose vaginal estrogens administered for the
relief of urogenital atrophy do not require
progestogen co-medication - Direct delivery of progestogen to the endometrial
cavity from the vagina or by an intrauterine
system is logical and may minimize systemic
effects
Climacteric 20071018194
89IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part I. Governing principles
- Androgen replacement should be reserved for women
with clinical signs and symptoms of androgen
insufficiency - In women with bilateral oophorectomy or adrenal
failure, androgen replacement has significant
beneficial effects, in particular on
health-related quality of life and sexual
function
Climacteric 20071018194
90IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapyGeneral
- HT remains the most effective therapy for
vasomotor and estrogen-deficient urogenital
symptoms - Other menopause-related complaints, such as joint
and muscle pains, mood swings, sleep disturbances
and sexual dysfunction (including reduced libido)
may improve during HT
Climacteric 20071018194
91IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapyGeneral
- Quality of life and sexuality are key factors to
be considered in the management of the aging
individual - The administration of individualized HT
(including androgenic preparations when
appropriate) improves both sexuality and overall
quality of life
Climacteric 20071018194
92IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapyPostmenopaus
al osteoporosis
- HT is effective in preventing the bone loss
associated with the menopause and decreases the
incidence of all osteoporosis-related fractures,
including vertebral and hip, even in patients at
low risk - Although the magnitude of decline in bone
turnover correlates with estrogen dosage, even
lower than standard-dose preparations maintain a
positive influence on bone indices in most women
Climacteric 20071018194
93IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapy
Postmenopausal osteoporosis
- HT is an appropriate first-line therapy in
postmenopausal women presenting with an increased
risk for fracture, particularly under the age of
60 years and for the prevention of bone loss in
women with premature menopause - The protective effect of HT on bone mineral
density declines after cessation of therapy at an
unpredictable rate, although some degree of
fracture protection may remain after cessation of
HT
Climacteric 20071018194
94IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapy
Postmenopausal osteoporosis
- The initiation of standard-dose HT is not
recommended for the sole purpose of the
prevention of fractures after the age of 60 years - The continuation of HT after the age of 60 for
the sole purpose of the prevention of fractures
should take into account the possible long-term
effects of the specific dose and method of
administration of HT, compared to other proven
therapies
Climacteric 20071018194
95IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapyCardiovascul
ar disease
- Cardiovascular disease is the principal cause of
morbidity and mortality in postmenopausal women - Major primary prevention measures (besides
smoking cessation, and diet control) are weight
loss, blood pressure reduction, and diabetes and
lipid control - There is evidence that HT may be cardioprotective
if started around the time of menopause and
continued long-term (often referred to as the
window of opportunity concept)
Climacteric 20071018194
96IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapyCardiovascul
ar disease
- HT markedly reduces the risk of diabetes and,
through improved insulin resistance, it has
positive effects on other related risk factors
for cardiovascular disease such as the lipid
profile and metabolic syndrome - In women less than 60 years old, recently
menopausal, without prevalent cardiovascular
disease, the initiation of HT does not cause
early harm, and may reduce cardiovascular
morbidity and mortality - Continuation of HT beyond the age of 60 should be
decided as a part of the overall risk-benefit
analysis
Climacteric 20071018194
97IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part II. Benefits of hormone therapy Other
- HT may reduce the risk of colon cancer
- HT initiated around the time of menopause or by
younger postmenopausal women is associated with a
reduced risk of Alzheimers disease - HT has benefits for connective tissue, skin,
joints and intervertebral disks
Climacteric 20071018194
98IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of HT
- Studies on the risks of postmenopausal hormone
use have mainly focused on breast and endometrial
cancer, venous thromboembolism (pulmonary
embolism or deep vein thrombosis), stroke and
coronary events
Climacteric 20071018194
99IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HTBreast cancer
- The incidence of breast cancer varies in
different countries. Therefore, currently
available data cannot necessarily be generalized
Climacteric 20071018194
100IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HTBreast cancer
- The degree of association between breast cancer
and postmenopausal HT remains controversial.
Women should be reassured that the possible risk
of breast cancer associated with HT is small
(less than 0.1 per annum)
Climacteric 20071018194
101IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HTBreast cancer
- For combined HT, observational data from the
Million Women Study suggested that breast cancer
risk was increased as early as the first year,
raising serious reservations on possible
methodologic flaws - On the contrary, randomized controlled data from
the Womens Health Initiative (WHI) Study
indicate that no increased risk is observed in
women initiating HT, for up to 7 years. It should
be noted that the majority of subjects in the WHI
Study were overweight or obese
Climacteric 20071018194
102IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HTBreast cancer
- Data from the WHI and Nurses Health Study
suggest that long-term estrogen-only
administration for 7 and 15 years, respectively,
does not increase the risk of breast cancer in
American women. Recent European observational
studies suggest that risk may increase after 5
years - There are insufficient data to evaluate the
possible differences in the incidence of breast
cancer using different types and routes of
estrogen, natural progesterone and progestogens,
and androgen administration
Climacteric 20071018194
103IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HTBreast cancer
- Baseline mammographic density correlates with
breast cancer risk. This does not necessarily
apply to the increase in mammographic density
induced by HT - The combined estrogenprogestogen therapy-related

104IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HT Endometrial cancer
- Unopposed estrogen administration induces a
dose-related stimulation of the endometrium - Women with a uterus should have progestogen
supplementation - Continuous combined estrogenprogestogen regimens
are associated with a lower incidence of
endometrial hyperplasia and cancer than occurs in
the normal population - Direct intrauterine delivery systems may have
advantages - Regimens containing low-/ultra-low-dose estrogen
and progestogen cause less endometrial
stimulation and less bleeding
Climacteric 20071018194
105IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HT Thromboembolism and cardiovascular events
- The HT-related risk for serious venous
thromboembolic events increases with age
(although minimal until age 60) and is also
positively associated with obesity and
thrombophilia - By avoiding first-pass hepatic metabolism,
transdermal estrogen may avert the risk
associated with oral HT - The impact on the risk of a thromboembolic event
may also be affected by progestogen, depending on
the type
Climacteric 20071018194
106IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part III. Potential serious adverse effects of
HT Thromboembolism and cardiovascular events
- Late starters of standard-dose HT may have a
transient slightly increased risk for coronary
events - The risk of stroke is correlated with age. HT may
increase the risk of stroke after the age of 60 - Safety data from studies of low-dose and
ultra-low-dose regimens of estrogen and
progestogen are encouraging
Climacteric 20071018194
107IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part IV Alternative treatments
- The efficacy and safety of complementary
alternative medicines have not been demonstrated
and further studies are required - Selective serotonin reuptake inhibitors,
selective noradrenaline reuptake inhibitors and
gabapentin are effective in reducing vasomotor
symptoms in short-term studies. Their long-term
safety needs further evaluation
Climacteric 20071018194
108IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part IV Alternative treatments
- There are no medical or scientific reasons to
recommend unregistered bioidentical hormones - The measurement of hormone levels in the saliva
is not clinically useful - These customized hormonal preparations have not
been tested in studies, and their purity and
risks are unknown
Climacteric 20071018194
109IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part V Conclusions
- There is urgent need for further research,
especially into the relative merits of lower
doses, regimens and routes of administration
Climacteric 20071018194
110IMS UPDATED RECOMMENDATIONS ON POSTMENOPAUSAL
HORMONE THERAPY
Part V Conclusions
- The safety of HT largely depends on age
- Women younger than 60 years should not be
concerned about the safety profile of HT - New data and re-analyses of older studies by
womens age show that, for most women, the
potential benefits of HT given for a clear
indication are many and the risks are few when
initiated within a few years of menopause

- Any physical activity is better than being
sedentary - Regular exercise reduces total and cardiovascular
mortality - Better metabolic profile, balance, muscle
strength, cognition and quality of life are

events, stroke, fractures and breast cancer are
significantly less frequent - Benefits far outweigh possible adverse
consequences the more the better, but too much
may cause harm
