Menopause Flashcards
Premature ovarian failure
Menopause before age 40
1%age <40, 0.1%
Peri-menopause
After reproductive years Before menopause Irregular menstraul cycles Endocrine changes Hot flushes Sleep disturbances Mood symptoms Vaginal dryness
STRAW staging system
Reproductive (-5 to -3a) -5=menarche Menopausal transition (-2 to -1) Post menopause (+1a to +2) -after final menstraul period
Perimenopause hormone levels
Inhibin B decreases
FSH increases
Oestrogen fluctuation and decline
luteal prof decrease
Desynchronized GnRH secretion
Impaired timing of LH surge
FSH increase
FSH values for peri and post
Peri >25
Post>70
Early menopause
Final MP between 40-45
Perimenopausal symptoms
Mood changes Sore breasts Bloating Headaches/migraines Periods-irregular in flow &pattern &symptoms Hot flushes/night sweats Sleep disturbances Formulation Irritability Fatigue
Menopause symptoms
Hot flushes/night sweats Sleep disturbance Joint pains Formulation Irritability Fatigue Urogenital symptoms Low libido
Consequences of menopause on the cardiovascular system
Visceral adiposity Dyslipidaemia (increase LDL, decrease HDL) Increased triglycerides Insulin resistance Increased BP Chronic inflammation
Activation of renin-angiotensin system, increased angiotensin II, increased endothelium 1, decreased NO synthase —>these leading to oxidative stress, vascular cell proliferation, vascular wall inflammation, arterial stiffness, endothelial dysfunction
Both lead to atherosclerosis and IHD and stroke
Beneficial effects of HRT on early atherosclerosis
Increased vasodilation
Decreased inflammatory activation
Decreased lesion progression
In established atherosclerosis: Decreased ER expression, function Decreased vasodilitation Increased inflammatory activation Increased plaque instability
How oestrogen deficiency works on bones
A number of cytokines are produced that inhibit osteoblastogenesis and stimulate the activity as well as prolong the life of osteoclasts
Bloods at a menopause consult
Lipids Blood glucose Vitamin D If fatigue: FBC Fe TFT B12 Renal Lfts
Contraception in the peri-menopause
Risk of pregnancy at 50 <1%
If menopause <50, continue contraception until 2 years post LMP
>50 yrs, continue for 1 year post LMP
Cease COCP by 51 - switch to non-hormonal/progestogen only method
How to initiate HRT
Daily continuous oestrogen - all HRT
Cyclical progesterone if <12 months from LMP (progesterone 10-14 days/month)
Continuous progestogen if >12 months since LMP
Causes of hot flushes apart from oestrogen deficiency
Alcohol consumption Carcinoid Hyperthyroidism Narcotic withdrawal Phaechromocytoma Medication side effects (vasodilaters, tamoxifen)
