Premature ovarian insufficiency Flashcards
What is premature ovarian insufficiency
Menopause before the age of 40
Pathophysiology of premature ovarian insufficiency
Decline in the normal activity of the ovaries at an early age. Hypogonadism means lack of negative on pituitary gland = excess gonadotropins (hypergonadotropism).
Hormone analysis: Raised LH and FSH, low oestrogen
Causes of premature ovarian insufficiency
Idiopathic (>50%), Iatrogenic (Chemotherapy, radiotherapy or surgery), Autoimmune, Genetics, Infection (mumps,TB)
Premature ovarian insufficiency presentation
Irregular menstrual periods, lack of menstrual periods, symptoms of low oestrogen levels e.g. hot flushes, night sweats, vaginal dryness
Premature ovarian insufficiency diagnosis
Younger than 40yrs with typical menopausal symptoms plus elevated FSH (>25 IU/l on two consecutive samples separated by more than 4 weeks)
Premature ovarian insufficiency risks
Higher risk of multiple conditions relating to lack of oestrogen inc. CVD, stroke, osteoporosis, dementia, Parkinsonism, cognitive impairment
Premature ovarian insufficiency management
HRT until at least age at which women normally go through menopause. Reduces risks associated with premature ovarian insufficiency.
Contraception still required, small chance of pregnancy
Can also give COCP
May be increased risk of VTE but reduced by using transdermal methods of HRT
