- vasomotor symptoms (night sweats, hot flushes) & irregular breathing
How and when do you diagnose menopause
- If the women is >45 yrs, you can diagnose it with no lab tests( e.g FSH& AMH)
- perimenopause: vasomotor symptoms& irregular bleeding
- menopause: amenorrhea for >12 months in women with a uterus
- menopause: based on symptoms on women without a uterus
-Can be more difficult to diagnose in women taking hormone medications to control heavy bleeding (e.g COCP & high doses of progesterone)

- FSH increases (lack of inhibitory feedback from oestrogen on hypothalamus)
What consequences does menopause cause?

- physical changes
- psychological changes
What are the long term consequences of menopause?
- osteoporosis as oestrogens are needed for the maintenance of bone mass in both males and females ,acting to suppress bone resorption by osteoclasts and to promote bone formation by osteoblasts
- CVD( coronary artery disease, stroke, venous thromboembolism, pulmonary embolism)
- vaginal dryness and atrophy
- alzheimers
What different hormonal treatment options are available for menopause?
- Oestrogen: reverse symptoms and effects of low oestrogen
- Progesterone: Necessary to protect the endometrium if uterus present

What different HRT preparations are available for menopause
- Oral
- Transdermal
- Implant
- Local
What is premature ovarian insufficiency?
- aka premature menopause or premature ovarian failure
- Diagnosis: amenorrhoea 4 months, FSH> 30U/L on two occasions 6 weeks apart, women less than 40yrs
- less common the younger you are
- In the case of idiopathic POI investigate via: cytogenetics, FMR1 premutation screening, anti-adrenal & anti-thyroid antibodies
