Why does menopause occur?

A
  • Occurs due to ovarian insufficiency as oestradiol (strongest of 3 oestrogens) falls
    • FSH rises
    • Some oestriol from conversion of adrenal androgens in adipose tissue
  • FSH level fluctuates in perimenopause
  • Menopausal transition can be natural or sudden following oophorectomy/chemotherapy/radiotherapy

Q

Describe the management of menopause?

A
  • Reduce risk of reduced bone mass (seen below)
  • Manage symptoms with hormone replacement therapy (HRT)
    • Local vaginal HRT – oestrogen pessary/ring/cream
      • Has local effects, so minimal systemic absorption
    • Systemic oestrogen transdermal/oral
      • Transdermal avoids first pass
      • a/oestrogen only if no uterus, if uterus present then a and b/oestrogen
    • Combined oestrogen (E) and progestogen (P) HRT
      • Could be cyclical combined – 14 days E and 14 days E and P, expect to bleed after the P use
      • Or continuous combined 28 days E and P oral/patch, except to be bleed free
    • Contraindications – current hormone dependent cancer such as breast or endometrium, current active liver disease, investigated abnormal bleeding
  • Manage symptoms with selective oestrogen receptor modulators (SERMs)
    • Such as tibolone
  • Phytoestrogen hers
    • Such as red clover/soya
  • Hyponotherapy, exercise, CBT
  • Non-hormonal lubricants for vaginal dryness

Q

What are possible complications of menopause?

A
  • Causes reduced bone mass
    • Investigated using DEXA scan where bone density is described as T score
    • Can lead to fractured hip/vertebra
    • Risk factors – thin, Caucasian, smoking, malabsorption of vitamin D or calcium, prolonged low oestrogen, oral corticosteroids, hyperthyroid
    • Prevention and treatment – weight bearing exercise, adequate calcium and vitamin D intake, bisphosphonates, denosumab
