17. Perimenopausal Period –I-
Perimenopause is a transitional period between reproductive ages and
menopause.
Clinically this period is defined as irregular menstrual bleeding.
In Perimenopause:
FSH increases (↑)
Inhibin decreases (↓)
LH normal (→)
Östrojen slightly increases (↑)
37 – 38 aged woman has approximately 25.000 follicules.
Rapid follicule expense starts in this period. This situation presents itself
as decrease in inhibin levels and increase in FSH levels.
18. Perimenopausal Period –II-
At this period the main problem is endometrial
hyperplasia which occurs due to irregular bleeding and
relatively increased estrogen levels.
19. Hormonal Equilibrium In Postmenopausal period-I-
In menopausal period FSH level increases 10-20 times,
LH level increases 3 times.
At postmenopausal period total estrogen production is
approximately 45 µgr in 24 hours.
Almost all of the estrogen level depends on peripheral
conversion of androstenodione and estrone level is
higher than estrodiol.
The ratio of Androgen/Estrogen changes in the favor
of androgens.
21. What Happens in Menopause ?
1.Body architecture changes:
Central fat increases.
Waist circumference increases.
2. Muscle mass decreases and generally fat tissue increases.This
condition is more evident in androgen deficiency syndrome :
Muscle tonus and vital energy decreases
Fatique sensation increases .
3. Skin wrinkles increases and they are more realized by the woman
2% of connective tissue and collagen decreases yearly.
38% of sweat and sebaseous gland secretion decreases.
4. Atrophy is developed in genitourinary system.
Atrophy in vaginal mucosa
Vaginal lubrication decreases, disparonia
