Q

What causes the hormonal changes during menopause?

A
  1. Declining reserves of oocytes and associated follicles leads to reduced oestrogen production in response to FSH and LH stimulation. 2. Therefore serum LH and FSH rise in response (lack of negative feedback). 3. Eventually insufficient oestrogen means the LH surge and subsequent ovulation do not occur, leading to anovulatory cycles

18
Q

What forms of HRT are recommended for women with a uterus?

A

Oral or transdermal (patch) combined oestrogen and progesterone e.g. tibolone for systemic i.e. vasomotor symptoms, mood disturbance. ■ Note - in situ Mirena can act as progesterone component of HRT. ■ Topical oestrogen gel for local i.e. vaginal symptoms.

19
Q

What forms of HRT are recommended for women withOUT a uterus?

A

Oral or transdermal oestrogen only treatment for systemic symptoms. ■ Topical oestrogen gel for local symptoms.

20
Q

How is HRT adapted for perimenopausal women?

A

Monthly or 3 monthly cyclical regime to produce a protective bleed: ● Oestrogen daily, plus progestogen for 12 days every 4 weeks or 3 months

21
Q

How is HRT prescribed for postmenopausal women?

A

(i.e. 12 months after LMP): ■ Cyclical or continuous combined regime: ● Cyclical (as above). ● Continuous oestrogen and progesterone daily

22
Q

What are the key risks associated with systemic HRT?

A

Increased risk of breast cancer, which rises with longer use. Increased risk of venous thromboembolism.

23
Q

Systemic HRT is associated with increased risk of _______. The longer its duration of use, the higher the associated risk.

A

Breast Cancer

24
Q

Systemic HRT is associated with increased risk of ___ ______

A

Venous Thromboembolism

25
Q

Does topical HRT carry the same risks as systemic HRT?

A

No, topical HRT is thought to have no effect on breast cancer risk due to minimal systemic absorption.

26
Q

What are the absolute contraindications to HRT?

A
  1. History of breast cancer, any oestrogen-dependent cancer, current undiagnosed PV bleeding, current endometrial hyperplasia. 2. History of idiopathic VTE (if not anticoagulated). 3. Thromboembolic disease e.g. MI, angina 4. Liver disease. 5. Inherited thrombophilia. 6. Pregnancy.
