12+ months after final menses
what is premature menopause
ovarian failure before age 40
what is considered early menopause
age 40-45
what is surgical menopause
cessation of menses due to BSO
what is perimenopause/transition
4-6 years of cycle changes and other symptoms before total cessation of menses
what are vasomotor perimenopause symptoms
hot flashes, night sweats, insomnia
What are psych preimenopasual symptoms
depression, irritability, mood swings
What are cognitive perimenopausal symptoms
concentration/memory issues
What are sexual perimenopausal symptoms

other: urinary incontinence, dry itchy skin, weight gain
Menstrual changes: shorter or longer cycles, irregular bleeding
What can effect the onset of menopause
smoking and malnutrition can make it earlier
what re the hormone changes with menopause
decreased ovarian synthesis of estrogens and progesterone
GnRH released at maximal frequency and amplitude (increase FSH by 4-fold)
what is androstenedione converted to
peripherally converted in fat and muscle to estrone
what are the types of estrogen
E1 (estrone)
E2 (estradiol)
E3 (estriol)
what is Estrone
E1 - made after menopause
what is Estradiol
E2 - most common type of estrogen
most potent and abundant during reproductive years
what is Estriol
E3 - main type of estrogen in a pregnant persons bloodstream, prepares for childbirth

What are early symptoms of estrogen loss
hot flashes
insomnia
irritability
what are the physical changes with estrogen loss
vaginal atrophy
skin atrophy
what are the disease with estrogen loss
osteoporosis
coronary heart diesease
what is luteal insufficiency
occurs after age 40, ovarian follicles become less responsive to FSH
-less inhibin and estradiol
-FSH levels increase further
-results in heavier menses
what is the shorted cycle stage of menstraul changes
luteal phase remains the same, follicular phase is shorter - overall cycle is shorted
higher FSH levels cause follicles to mautre faster and produce enough estradiol to trigger an LH surge
what is anovulation
accelerated declined in responsive follicles
anovulation more common and cycle length and variability increase
bleeding occurs because of fluctuations of estrogen levels
bleeding episodes spread out and then stop
why does skin temperature rise with menopause
peripheral vasodilation followed by a drop in core temperature
what is the most common reason that women seek medical care during menopause
vasomotor symptoms, skin temperature, chills, anxiety, heart palpitations
