Q

What is the cause of menopause?

A

A lack of ovarian follicular function, resulting in changes in the sex hormones associated with the menstrual cycle:

  • Oestrogen and progesterone are low
  • LH and FSH are high, in response to an absence of a negative feedback from oestrogen

Q

Describe how a decline in development of ovarian follicles leads to menopause

A

1) Begins with decline in development of ovarian follicles

2) Without growth of follicles, there is a reduced production of oestrogen (usually produced by granulosa cells that surround follicles)

3) As oestrogen falls in perimenopausal period, there is an absence of a negative feedback on the pituitary gland, and increasing levels of FSH and LH (oestrogen has a negative feedback effect on pituitary gland, suppressing LH and FSH)

4) Falling follicular development means ovulation does not occur (anovulation), resulting in irregular menstrual cycles

5) Without oestrogen, endometrium doesn’t develop, leading to a lack of menstruation (amenorrhoea)

6) Lower oestrogen also causes perimenopausal symptoms

3) Increased risk of venous thromboembolism (2 – 3 times the background risk)

4) Increased risk of stroke and coronary artery disease with long term use in older women (but NO increased risk with oestrogen-only HRT)

5) The evidence is inconclusive about ovarian cancer, and if there is an increase in risk, it is minimal

44
Q

How can the risk of VTE in HRT be reduced?

A

by using patches rather than pills

  • Take a family history to assess the risk of oestrogen dependent cancers (e.g. breast cancer) and VTE
  • Check the body mass index (BMI) and blood pressure
  • Ensure cervical and breast screening is up to date
  • Encourage lifestyle changes that are likely to improve symptoms and reduce risks
46
Q

What are the 3 steps to consider when choosing the HRT formulation?

A
  1. Do they have local or systemic symptoms?
    a) Local symptoms: use topical treatments such as topical oestrogen cream or tablets
    b) Systemic symptoms: use systemic treatment – go to step 2
  2. Does the woman have a uterus?
    a) No uterus: use continuous oestrogen-only HRT
    b) Has uterus: add progesterone (combined HRT) – go to step 3
  3. Have they had a period in the last 12 months?
    a) Perimenopausal: give cyclical combined HRT
    b) Postmenopausal (more than 12 months since last period): give continuous combined HRT
47

80
Q

Pathophysiology in premature ovarian insufficiency?

A

Characterised by hypergonadotropic hypogonadism.

Under-activity of the gonads (hypogonadism) means there is a lack of negative feedback on the pituitary gland, resulting in an excess of the gonadotropins (hypergonadotropism).

85
Q

How is premature ovarian insufficiency diagnosed?

A

Can be diagnosed in women;

a) younger than 40 years with typical menopausal symptoms
b) plus elevated FSH.

86
Q

What FSH levels are required to diagnose premature ovarian insufficiency?

Who are these difficult to interpret in?

A

The FSH level needs to be persistently raised (more than 25 IU/l) on two consecutive samples separated by more than four weeks to make a diagnosis.

- Stroke
- Osteoporosis
- Cognitive impairment
- Dementia
- Parkinsonism

88
Q

Management of premature ovarian failure?
