FSH will be high in both
What is treatment for POI?

CVD
dementia
Why do vasomotor symptoms occur in menopause?
due to exaggerated peripheral vasodilation to slight changes in external temperature
What are triggers for vasomotor symptoms?
alcohol, caffeine, sweating

What kind of hormones are used in HRT, and in what combination?
OESTROGEN ONLY if no longer has a uterus
OESTROGEN + PROGESTERONE otherwise (can be CYCLICAL or CONTINOUS COMBINED)
What is the function of progesterone in HRT?
Protects the endometrium from cancer
What are routes of hormone therapy administration?
Oral / transdermal / coil / gel
What is the benefit of transdermal route?
It bypasses the liver
What are absolute contraindications for HRT?
Suspected pregnancy Breast cancer Endometrial cancer Active liver disease Uncontrolled HTN LVTE Thrombophilia Otosclerosis
How does HRT affect cancer?
It does not drastically increase breast cancer
It just promotes growth of the cancer cells
What is the hormone that increases risk of breast cancer?
Progesterone
What is the hormone that increases risk of endometrial cancer?
Oestrogen
Why do you need to give progesterone in HRT ?For which women is this necessary?
In women who have a uterus / with endometriosis tissue
It protects against endometrial cancer
What is cyclical HRT composed of?
Oestrogen continuously
Progesterone only on day 0-12
What women is cyclical HRT appropriate for’
LMP <1 yr prior / still having periods
Good for POI to preserve fertility
What women is continuous combined HRT appropriate for
Women with LMP >2 yrs prior
What is the benefit of continuous combined HRT compared to cyclical?
Continuous progesterone reduces risk of endometrial cancer
BUT
It increases risk of breast cancer
What is the impact of HRT on CVD?
Depends on women’s age
- younger;: protective
- older: increases risk

The least duration of time possible
What kind of HRT does not have increased VTE risk?
TRANSDERMAL
what is the effect of adding a progesterone to HRT on VTE?
Adding a Progesterone will INCREASE VTE risk
What kind of progesterone in HRT will reduce risk of endometrial cancer
CONTINUOUS combined (so continuous progesterone)
What kinds of cancer does estrogen cause
Endometrial
Ovarian
What kinds of cancer does progesterone cause
Breast, cervical
What cancer is progesterone protective for
Endometrial
