Complications of Menopause Jianhong Zhou
Definition • Menopause is defined by 12 months of amenorrhea after the final menstrual period (FMP). • The median age of menopause is 51.4 years, with 90% becoming menopausal between the ages of 45 to 55 years of age. • Premature menopause is defined as the permanent cessation of menses occurring before 40 years of age.
Various physiologic and hormonal changes occur • A decrease in estrogen • Increase in FSH • Classic symptoms such as • Hot flashes • Night sweats • Mood swings • Vaginal dryness
How often and serious ? • 10% of women will begin during perimenopause • 50% will experience an increase in symptoms during menopause • Symptoms may last during the first year or two of menopause • Rarely do symptoms extend beyond the first 5 years of menopause
Etiology • Menopause is heralded by menstrual irregularity as the number of oocytes capable of responding to FSH and LH decreases • Anovulation becomes more frequent • LH and FSH levels gradually rise because of decreased negative feedback from diminished E production
Inhibin Estradiol Hypothalamus Pituitary gland Ovary=No gonadal E FSH,LH FSH,LH Norepinephrine Dopamine Prostaglandins Uterus Vagina Breast Bone Cardiovascular system Hot flashes Insomnia Depression Osteoporosis Atherosclerosis Atrophy
Diagnosis • History • Physical exam • Confirmed by testing FSH levels
Diagnosis -History • Average age of 51 • Complaining of amenorrhea, vasomotor instability, sweats, mood changes, depression, dyspareunia, and dysuria • Disappear within 12 months generally • Remain for years
Diagnosis-PE • Decrease in breast size and change in texture • Vaginal, urethral, cervical atrophy • Be consistent with decreased E
Diagnosis-FSH • If there is any question about the diagnosis, an elevated FSH is diagnostic of menopause • During the perimenopausal period, the FSH level may be increased or decreased. • FSH is best reserved for patients with a combination of amenorrhea or oligomenorrhea and menopausal symptoms
Pathogenesis • Long-term consequences of the estrogen decrease • Osteoporosis -bone resorption accelerates • Atherosclerosis-increased risk for coronary artery disease
HRT and ERT • HRT –hormone replacement therapy-refers to the use of a combination of estrogen and progesterone to treat menopausal related symptoms in women who still have their uterus in situ • Menopausal symptoms are due to decreased E levels • The E component on HRT supplies the patient with an exogenous source of E and thereby treats the symptoms of menopause
HRT and ERT • Unopposed estrogen exposure can result in endometrial hyperplasia or cancer • Progestins must be used to decrease the risk of endometrial hyperplasia and cancer in women who still have a uterus in situ • Estrogen replacement therapy-ERT can be used for women with menopausal symptoms who have undergone a hysterectomy
HRT and ERT • The other major value of HRT is the prevention and treatment of osteoporosis • A important preventative measure—since 15% of women over age 50 will be diagnosed with osteoporosis and 50% with osteopenia • A woman can lose 20% of her original bone density in the first 5 to 7 years after menopause
HRT and ERT • The risks and benefits have been the center of numerous studies over the past few decades • Each patient’s symptoms, risk factors, and related risks and benefits should be individually evaluated
Contraindications to HRT • Chronic liver impairment • Pregnancy • Known estrogen-dependent neoplasm • History of thromboembolic disease • Undiagnosed vaginal bleeding
Additional therapeutic regimens • Alternative regimens for postmenopausal women who are unable or unwilling to take HRT, should be targeted toward the individual’s symptoms and treatment goals • Vasomotor flushes • Vaginal atrophy • The prevention and treatment for osteoporosis
How to treat vasomotor flushes • Be managed with clonidine • Selective serotonin reuptake inhibitors (SSRIs)
How to treat vaginal atrophy • Locally use with lubricants and moisturizers • Vaginal estrogen with only minimal systemic absorption
Prevention and treatment for osteoporosis • Calcium and vitamin D supplementation • Calcitonin • Raloxifene • Weight-bearing exercise • Reduction in smoking and in caffeine and alcohol intake
