Period Related Flashcards
What is menopause?
retrospective diagnosis, made after a woman has had no periods for 12 months. It is defined as a permanent end to menstruation
point at which menstruation stops.
Around when do women experience menopause?
On average, women experience the menopause around the age of 51 years, although this can vary significantly. Menopause is a normal process affecting all women reaching a suitable age.
What is postmenopause?
describes the period from 12 months after the final menstrual period onwards.
What is perimenopause?
time around the menopause, where the woman may be experiencing vasomotor symptoms and irregular periods
includes the time leading up to the last menstrual period, and the 12 months afterwards. This is typically in women older than 45 years.
What is premature menopause?
menopause before the age of 40 years. It is the result of premature ovarian insufficiency.
What is menopause caused by?
caused by a lack of ovarian follicular function, resulting in changes in the sex hormones associated with the menstrual cycle:
Oestrogen and progesterone levels are low
LH and FSH levels are high, in response to an absence of negative feedback from oestrogen
What is the epidemiology of menopause?
Average age of menopause is 51 years old; it typically occurs between 40 and 60 years
old
What is the physiology of a period?
- Processo of primordial follicles maturing into primary and secondary alway occurs
- start of cycle FSH causes development of secondary follicles
- follicles grow , granulose cells surrounding increase oestrogen
What is the aetiology and physiology of menopause?
- Declining reserves of oocytes and associated follicles leads to reduced oestrogen
production in response to FSH and LH stimulation. - Therefore serum LH and FSH rise in response (lack of negative feedback).
- Eventually insufficient oestrogen means the LH surge and subsequent ovulation do not
occur, leading to anovulatory cycles.
How does the process of menopause occur?
- decline in the amount of follicles
- thus no follicle matures- no oestrogen is released
- causes more FSH release to compensate
- overtime excess FSH causes desensitisation of the follicle receptors
- no more ovulation = no more period
What does the failing follicular development cause in menopause?
- means ovulation does not occur (anovulation),
- resulting in irregular menstrual cycles.
- Without oestrogen, the endometrium does not develop, leading to a lack of menstruation (amenorrhoea).
- Lower levels of oestrogen also cause the perimenopausal symptoms.
S + S of perimenopausal symptoms
Hot flushes
Emotional lability or low mood
Premenstrual syndrome
Irregular periods
Joint pains
Heavier or lighter periods
Vaginal dryness and atrophy
Reduced libido
○ Menstrual irregularity leading to amenorrhea
○ Vasomotor symptoms (hot flushes / night sweats
○ Mood disturbance
○ Sleep disturbance
What are the risks/ risk factors of menopause?
A lack of oestrogen increases the risk of certain conditions:
Cardiovascular disease and stroke
Osteoporosis
Pelvic organ prolapse
Urinary incontinence
How do we make a diagnosis for menopause?
A diagnosis of perimenopause and menopause can be made in women over 45 years with typical symptoms, without performing any investigations.
NICE guidelines (2015) recommend considering an FSH blood test to help with the diagnosis in:
Women under 40 years with suspected premature menopause
Women aged 40 – 45 years with menopausal symptoms or a change in the menstrual cycle
What are the complications for menopause?
● Osteoporosis - due to increased bone turnover (normal oestrogen levels inhibit
osteoclast activity).
● Increased cardiovascular risk - due to alterations in LDL:HDL ratio, raised serum
cholesterol, arterial stiffening (among many other factors that are not entirely clear).
What are the investigations for menopause?
● Typically diagnosed clinically - investigations are usually not indicated in women with
menopausal symptoms over the age of 45.
● If indicated:
○ Serum FSH - elevated
○ Serum oestradiol - reduced
Contraception for menopause?
Fertility gradually declines after 40 years of age. However, women should still consider themselves fertile. Pregnancy after 40 is associated with increased risks and complications. Women need to use effective contraception for:
Two years after the last menstrual period in women under 50
One year after the last menstrual period in women over 50
What are the good contraception options for menopause?
- Barrier methods
- Mirena or copper coil
- Progesterone only pill
- Progesterone implant
- Progesterone depot injection (under 45 years)
- Sterilisation
Combined oral contraceptive pill
- The combined oral contraceptive pill is UKMEC 2 (the advantages generally outweigh the risks) after aged 40, and can be used up to age 50 years if there are no other contraindications.
- Consider combined oral contraceptive pills containing norethisterone or levonorgestrel in women over 40, due to the relatively lower risk of venous thromboembolism compared with other options.
What is treatment of menopause based on?
- Treatment can be beneficial for both symptomatic relief and cardiovascular / osteoporotic
risk. - HRT should be prescribed in the lowest effective dose for the shortest duration of
treatment possible
What is the first line management for menopause?
lifestyle measures:
○ Regular excess
○ Weight loss (as necessary)
○ Avoidance of triggers (smoking, alcohol, spicy food).
What is second line management for menopause?
hormone replacement therapy (HRT):
○ Women with a uterus:
■ Oral or transdermal (patch) combined oestrogen and progesterone e.g.
tibolone for systemic i.e. vasomotor symptoms, mood disturbance.
■ Note - in situ Mirena can act as progesterone component of HRT.
■ Topical oestrogen gel for local i.e. vaginal symptoms.
○ Women without a uterus:
■ Oral or transdermal oestrogen only treatment for systemic symptoms.
■ Topical oestrogen gel for local symptoms.
○ HRT is prescribed in different regimens depending on the woman’s stage of
menopause.
What is the management for perimenopausal women and postmenopausal women?
For perimenopausal women:
■ Monthly or 3 monthly cyclical regime to produce a protective bleed:
● Oestrogen daily, plus progestogen for 12 days every 4 weeks or 3
months.
○ For postmenopausal women (i.e. 12 months after LMP):
■ Cyclical or continuous combined regime:
● Cyclical (as above).
● Continuous oestrogen and progesterone daily.
How do we manage perimenopausal symptoms?
- No treatment
- Hormone replacement therapy (HRT)
- Tibolone, a synthetic steroid hormone that acts as continuous combined HRT (only after 12 months of amenorrhoea)
- Clonidine, which act as agonists of alpha-adrenergic and imidazoline receptors
- Cognitive behavioural therapy (CBT)
- SSRI antidepressants, such as fluoxetine or citalopram
- Testosterone can be used to treat reduced libido (usually as a gel or cream)
- Vaginal oestrogen cream or tablets, to help with vaginal dryness and atrophy (can be used alongside systemic HRT)
- Vaginal moisturisers, such as Sylk, Replens and YES
What are the risks of HRT?
● Systemic HRT is associated with increased risk of breast cancer. The longer its duration
of use, the higher the associated risk.
○ Topical HRT is thought to have no effect on breast cancer risk due to minimal
systemic absorption.
● Systemic HRT is associated with increased risk of venous thromboembolism.
What are the absolute contraindications to HRT?
- History of breast cancer, any oestrogen-dependent cancer, current undiagnosed PV
bleeding, current endometrial hyperplasia. - History of idiopathic VTE (if not anticoagulated).
- Thromboembolic disease e.g. MI, angina
- Liver disease.
- Inherited thrombophilia.
- Pregnancy.
What is adenomyosis?
endometrial tissue inside the myometrium (muscle layer of the uterus).
When is adenomyosis most common?
more common in later reproductive years and those that have had several pregnancies (multiparous). It occurs in around 10% of women overall. It may occur alone, or alongside endometriosis or fibroids
What is adenomyosis dependent on?
condition is hormone-dependent, and symptoms tend to resolve after menopause, similarly to endometriosis and fibroids.
What is the cause of of adenomyosis?
cause is not fully understood, and multiple factors are involved, including sex hormones, trauma and inflammation
How do women with adenomyosis present?
- Painful periods (dysmenorrhoea)
- Heavy periods (menorrhagia)
- Pain during intercourse (dyspareunia)
- It may also present with infertility or pregnancy-related complications. Around a third of patients are asymptomatic.
- boggy uterus
Examination can demonstrate an enlarged and tender uterus. It will feel more soft than a uterus containing fibroids.
Investigations for adenomyosis
Transvaginal ultrasound of the pelvis is the first-line investigation for suspected adenomyosis.
MRI and transabdominal ultrasound are alternative investigations where transvaginal ultrasound is not suitable.
The gold standard is to perform a histological examination of the uterus after a hysterectomy. However, this is not usually a suitable way of establishing the diagnosis for obvious reasons.
What does management for adenomyosis depend on?
symptoms, age and plans for pregnancy.
NICE recommend the same treatment for adenomyosis as for heavy menstrual bleeding.
What do we give women who do NOT want contraception for symptomatic relief?
- Tranexamic acid when there is no associated pain (antifibrinolytic – reduces bleeding)
- Mefenamic acid when there is associated pain (NSAID – reduces bleeding and pain)
What is the management when contraception is wanted or acceptable?
- Mirena coil (first line)
- Combined oral contraceptive pill
- Cyclical oral progestogens
- Progesterone only medications such as the pill, implant or depot injection may also be helpful.
What are some alternative options for adenomyosis?
- GnRH analogues to induce a menopause-like state
- Endometrial ablation
- Uterine artery embolisation
- Hysterectomy
What happens with adenomyosis and pregnancy?
- Infertility
- Miscarriage
- Preterm birth
- Small for gestational age
- Preterm premature rupture of membranes
- Malpresentation
- Need for caesarean section
- Postpartum haemorrhage
