appropriate to investigate

menopausal symptoms with patients
– To be able to prescribe HRT safetly

Review subject of menopause
Discuss management of menopausal symptoms
Look in more depth at HRT preparations
Look at the first consultation for HRT
Discuss clinical scenarios
Menopause Definitions
• Menopause is defined as the permanent cessation of
menstruation resulting from the loss of ovarian follicular
activity.
• Amenorrhoea for 1 year in patients > 50 or for 2 years in
patients <50
• Perimenopause is the period leading up to the
menopause when the features of menopause commence
• Premature menopause occurs under age 45 years
Physiology
• Each ovary has a certain number of oocytes from birth which
steadily decreases until we are approximately 50 years old
when the stock becomes exhausted
• During the perimenopause follicular activity fails, oestrogen
levels decrease and the pituitary gland produces increased
amounts of LH and FSH due to negative feedback.
• Cycles become anovulatory, follicular development stops, the
endometrium is no longer stimulated and amenorrhoea
occurs
Communication
• ‘A natural menopause occurs because as you
get older, your ovaries stop producing eggs
and make less of the main female hormone
oestrogen. The symptoms you are
experiencing are due to low levels of
oestrogen’
• ‘It signals the end of the fertile phase of a
woman’s life’
Incidence of Symptoms
• What proportion of women;
– experience some menopausal symptoms in their lifetime?
• 80%
– find their menopausal symptoms distressing?
• 45%
– experience hot flushes?
• 80%
– experience vaginal symptoms in the early postmenopausal period?
• 30%
– experience vaginal symptoms in the late postmenopausal period?
• 47%
– seek medical advice?
• 10%
Symptoms of Menopause
• Natural history;
– Symptoms start and increase from 2 years prior to the final menstrual
period, peak at one year following it and return to normal after 5 years
– Varies widely
•
•
•
•
•
•
•
Menstrual irregularity
Hot flushes and sweats
Sleep disturbances
Vaginal dryness
Urinary symptoms
Mood changes
Loss of libido
• Osteoporosis and CVD and stroke risk increase
Investigations
• Not necessary in most cases
• FSH
– Levels vary in perimenopause so single measures
unreliable.
– >30 IU/L – postmenopausal range
– >12 IU/L – raised in women still menstruating
• Other hormone tests – not useful
• TFTs
When is FSH Helpful?
•
Premature menopause
– Measure on day 3-5 of cycle
– If amenorrhoeic take 2 samples 2 weeks apart
•
Hysterectomy with conservation of ovaries
– Measure on 2 or more occasions at least 1-2 months apart
•
Women using hormonal contraception
– Must be off COCP for at least 6 weeks before testing. Can start
progestorone only preparation.
– Measure on 2 or more occasions at least 1-2 months apart
– A level in the menopause range in 2 or more occasions suggests ovarian
failure
– May still be at risk of becoming pregnant!
Premature Menopause
• Defined as menopause before age 45
• Causes;
– Primary ovarian failure
– Surgically induced menopause
– Radiation induced
– Chemotherapy induced
– May be linked with smoking, lower socioeconomic groups, BMI,
family history
• Refer any women under 40
• Prescribe HRT for osteoporosis prevention
• Stop HRT at normal age of menopause (50)
Management of Menopause
• Reassurance
• Education, lifestyle changes
• HRT
• Alternatives
Lifestyle changes
• Hot flushes and night sweats
– Regular exercise, lighter clothing, sleep in a cooler room, stress
management
– Avoid triggers
• Sleep disturbances
– Avoid exercise late in the day
– Maintain regular routine
• Mood and anxiety
– Adequate sleep, regular exercise, relaxation exercises
• Cognitive symptoms
– Adequate sleep, regular exercise
Benefits of HRT
• Effective for;
– Treating vasomotor symptoms
– Treating urogenital symptoms
– Treating sleep or mood disorders if associated
with flushes or night sweats
– Preventing osteoporosis
– Reducing risk of colon cancer
• Improves quality of life and sexual function in
symptomatic women
Side Effects
• Oestrogen related
– Nausea, headaches, breast tenderness, fluid retention,
headaches
– If side effects occur advise to persist for 3/12
– Try reducing dosage
– Try swapping oestrogen types (estradiol/conjugated oestrogens)
– Try changing mode of delivery
• Progestogen related
–
–
–
–
Bloating, Mood swings, headaches, backache
Less androgenic progestogens produce less side effects
Change to continuous therapy if postmenopausal
If problem is bleeding then change to more androgenic
progestogen or increased progestogen dose

Systemic Oral HRT
• Cyclical combined
– Use in perimenopause
– Have monthly withdrawl bleeds

– No bleed
– If bleeding beyond 3-6 months, needs
further ix

• Vaginal preparations
– Pessaries, creams, rings
– Eg vagifem tablets, premarin
• Implants, gels
Alternatives
Alternatives
• General rule is to advise against herbal medications.
• Many may contain oestrogenic compounds.
• Women may be taking more hormones by using these than they would
with HRT.
• They are often not regulated by a governing body.
• Some studies suggest diet high in soy and isoflavones reduces severity and
frequency of symptoms. They are safe.
•

•
•
Foot massage, reflexology – no evidence
Evening primrose oil – no evidence
Black Cohosh – limited evidence
Red Clover – limited evidence, no health concerns
Dong Quai – no evidence
• RCOG – SAC Paper 6 – alternatives to HRT for the management of
symptoms of the menopause
Medical Alternatives
• Tibolone – synthetic steroid with weak oestrogenic, progestogenic
and androgenic properties.
• Clonidine – alpha 2 agonist which helps with vasomotor symptoms.
Useful for patients with hx of breast cancer.
• SSRIs can reduce vasomotor symptoms.
• Gabapentin reduces severity and frequency of hot flushes
• Progestogens – may improve hot flushes but there are concerns
about risk of breast cancer
• Replens – vaginal bio adhesive moisturiser
First Consultation
• History
–
–
–
–
–
–
–
confirm menopause clinically
LMP
Symptoms
Gynae history – smears, mammograms
Risk factor for osteoporosis
PMH/FH breast ca/CHD/thromboembolism
Contraception
• Examination
– Blood pressure
– Height and weight
– Breast exam?
First Consultation Ctd
• ICE – Depression, anxiety, effect on life
• Investigations?
• Management
– Lifestyle changes
– If starting HRT
•
•
•
•
discuss benefits, risks, side effects
Ensure no contraindications
Discuss different preparations
Discuss contraception
– Alternatives
• Safety net – investigate PCB, bleeding 1 year after LMP
• Arrange follow up
Follow Up
• Reassess after 3 months then annually
• Follow up consultations should cover;
– Assessing effectiveness
– Enquiring about side effects
– Ask about bleeding pattern
– Check weight and BP
– Ensure she examines her breasts regularly
• If on cyclical treatment, consider changing to continuous if she is
considered to be postmenopausal. This is usually considered to be
– If she is over 54 years or;
– If they have had previous raised FSH levels or amenorrhoea or;
– If they have been on cyclical regimes for at least 2 years
Stopping HRT
• General rule is to stop after 1-2 years to see if
symptoms have gone.
• If they recur, can try lower dose or try different
method.
• Stop HRT 4-6 weeks prior to major surgery.
• If started for early menopause, stop at age 50.

–
–
–
–
–
–
–
–
–

• British Menopause Society
• Daisy Network Premature Menopause
Support Group
• National Prescribing Centre website for risk
charts (decision aids)
Summary
• Menopause symptoms can be managed with
lifestyle advice and medical treatment
• HRT is the most affective treatment but is
associated with risks so should be used at the
lowest dose for the shortest time necessary
• Women should be allowed to make an informed
decision regarding starting and continuing HRT
• More data is needed on complementary
therapies
