Look for hyperprolactinaemia
Why might you do TFTs in someone with amenorrheoa?
Look for primary hypothyroidism
When might you do an MRI head in someone with amenorrhoea?
If serum prolactin levels are high - look for pituitary tumour causing hyperprolactinaemia

What investigations would you consider doing in someone with menorrhagia?
- Bedside - pregnancy test
- Bloods - FBC, TFTs, Testosterone, coagulation screen
- Imaging - Pelvic USS
- Other - biopsy, hysteroscopy
Why might you do an FBC in someone with menorrhagia?
Look for signs of anaemia
Why might you do TFTs in someone with menorrhagia?
Look for Hypothyroidism
What should be considered as first line treatment for menorrhagia?
Mirena IUS
How does the mirena IUS help with menorrhagia?
Releases levonogestral into the endometrial cavity, leading to atrophy
What medications can be used to manage menorrhagia?
- Mirena IUS
-
Taken during bleeding
- Antifibrinolytics - Tranexamic acid
- NSAIDs
- COCP
- Progestogen injection
Why are NSAIDS/tranexamic acid used during bleeding in menorrhagic patients?
Reduce blood loss
What surgical options are available for managing menorrhagia?
Consider benefits and risk of each - reserved for non-responders to medication
- Endometrial ablation - thermal balloon, microwave, electrical impedence
- Uterine artery embolisation
- Myomectomy
- Hysterectomy
What is premenstrual syndrome?

52
What is peri-menopause?
Transition from cyclic menstrual bleeding to a total cessation of menses happens over about 4 years. It is marked irregularity and periods of amenorrhoea ue to declining progesterone and oestradial levels
What are features of the menopause?

What happens to levels of LH/FSH in the menopause?
Increase due to reduced oestrogen negative feedback
What are features of hot flushes experienced in menopause?
Last about 3 minutes
- Feeling of warmth
- Nausea
- Palpitations
- Sweating
Why are menopausal women at increased risk of UTI?
Due to vaginal glycogen depletion, leading to increased vaginal pH
