Natural menopause is a retrospective diagnosis and defined as 12 months of
amenorrhea without another pathologic cause
🔸
Climacteric
which is by dictionary definition is period of life when fertility and sexual activity decline.
🔸It isPremenopause:
3-5 years period before menopause with increase frequent
It is a wide term leading to: irregular anovulatory bleeding followed by episodes of amenorrhea
-*Pre Menopause 🔸
and intermittent menopausal symptoms.
Post menopause:

It is the period of life after menopause
Premature menopause:

-*Post Menopause
Is menopause before the age of 40 years, occurs in approximately 1%
The phase in the aging process of women marking the transition from the reproductive stage of
of life to the non-reproductive stagefrom 45-55 years.
🔸The number of primordial follicle decline even before birth but dramatic
pathophysiology
🔸
just before menopause.
🔸 Increase FSH, LH from about 10 years before menopause.
Close to menopause:
There will be
-anovulation
-inadequate Leuteal phase → decrease progesterone but not estrogen
level → lead to DUB and endometrial Hyperplasia
🔸 At menopause dramatic decrease of estrogen→menstruation ceases
🔸
and symptoms of menopause started.
But still ovarian stroma produce →small androstenedione and
testosterone but, main postmenopausal estrogen is estrone produced by
🔸
Peripheral fat from adrenal androgen.
The age of menopause appears to be genetically determined and is
unaffected by race, socioeconomic status, age at menarche, or number of
🔸
prior ovulations
Smoking, chemotherapy, radiotherapy , surgery on ovaries and
hysterectomy despite retention of ovaries may cause early menopause
genitourinary atrophy
-Vaginal epithelium becomes thin and palewith loss of rugae
-The PH increase
Symptoms of Menopause: -This will leads to atrophic vaginitis, dysparunia and purities (libido
Menopause and 1.Vasomotor instability: unchanged)
1. Hot flushes cutaneous vasodilatation *vaginitis due to thinning of epithelium, ↓ PH and lubrication.
Climacteric - occurs in 75% of women *dyspariunia→due to decrease vascularity and dryness
- more severe after surgical menopause -decrease size of cervix and mucus with retract of squamocolumnar
- continue for 1 year (SC) junction into the endocervical canal.

The mechanism is unknown but may be due to hypothalamic thermoregulatory center of dysuria, UTI, and urge, frequency , nocturia and incontinence
-Decrease size of breast and benign cysts

alteration due to decline estrogen

Hot flushes may precedes menopause by months to years
skin ,hair and nail changes:
It is common at night causing sleep disturbance -Estrogen influences skin thickness.
2.Menstrual Changes -With declining estrogen production, skin tends to become thin, less
Most women note a gradual tapering in both amount and duration of flow elastic, and eventually more susceptible to abrasion and trauma.
Estrogen replacement helps restore the thickness and elasticity of skin.
A minority of women have more frequent and heavier bleeding Estrogen therapy also helps to slow the formation of wrinkles.
Abrupt cessation of menses is fairly rare

Osteoporosis:
- bone mass reach peak at the end of their 3rd decade of life.
- After 40years bone resorption exceeds bone formation by 0.5% per year.
- This negative balance increase after menopause to a loss of 5% of bone per
year.
diagnosis and investigation
medication: The Triad of:
- ERT(Estrogen Replacement Therapy) Hot flushes
-b. Biphosphonate (Fosamax) that inhibit osteoclastic activity & minimal S/E Amenorrhea
-c. Raloxifene (Evista) is selective oestrogen receptors Increase FSH > 15 i.u./L
-moderator [SERMs] that bind with a high affinity to estrogen receptors. It Before starting treatment: You should perform

-d. Calcitonin inhibit osteoclastic activity
-e. Calcium Supplement &Vit D.
-Increase calcium intake 1000mg /day 🔸
treatment
Estrogen – a minimum of 2mg of oestradiol is
needed to maintain bone mass and relief symptoms of
-Vitamin D supplementation 400-800IU/day
cardiovascular system :

menopause.
Women with uterus – add progestin at last 10 days
-CVD is now the leading cause of death among post menopausal women 🔸
to prevent endometrial Hyperplastic
Sequential Regimens- used in patient close to
-before menopause, risk of heart attack is 1/3 of man
-after menopause increase in women become the same of man at an age of 🔸
menopause.
Oestrogen – in the first ½ of 28 day per pack
70years
- Because of effect of estrogen: 🔸
&Oestrogen&Progetin in 2nd 1/12 of 28 day pack.
Combined continuous therapy who has
Progesterone everyday – is useful for women who are
*Before menopause: increase HDL & decrease LDL.
*decrease Atherogenic plague formation by direct action on vascular few years past the menopause and who do not to have
endothelium
* After menopause:HDL : LDL ratio become closer to male ratio 🔸
vaginal bleeding.
There is evidence that increase risk of endometrial
cancer with sequential regimens for > 5 years while on
combined continuous regimens decrease risk of Cancer.
urogenital system :
The Urethra and vagina have a high concentration of estrogen receptors and there
is significant evidence to support one use of estrogen in treatment of urogenital
symptoms such as (recurrent UTI, vaginitis and dysparunia)
