- Has anyone in your family ever had endometrial or colon cancer?
- Are you on any medications?

How would you define menorrhagia?
- Objectively, menorrhagia can be defined as a menstrual blood loss of >80ml/month
- The average is 40ml/month -Approximately 10% of the female population will bleed this much
- The significance of this is that women are likely to develop iron deficiency anaemia at this level of blood loss
- However, only half of women who complain of heavy periods will actually meet this objective criteria – menorrhagia could also be considered as menstrual bleeding which is sufficient to cause distress or disruption to the woman’s life
How do you assess blood loss in menorrhagia?
- Various studies have shown that actually number of towels/tampons used, passage of clots and duration of bleeding actually bear little relation to the amount of blood lost
- Flooding and the use of double protection are indicative of pathological levels of blood loss, as is iron deficiency anaemia
- Most important indication may be the effect it is having
Name the causes of menorrhagia
Uterine disease
- Benign: fibroids, adenomyosis, pelvic infection, endometrial polyp
- Malignant: endometrial cancer, cervical cancer
Systemic disorders (v rare)
- Hypo/Hyperthyroidism
- Hepatic disease
- Renal disease
- Clotting abnormalities
What examinations would you like to perform?
- General inspection: examine woman looking for features of underlying causes and also for features of iron deficiency anaemia
- Abdominal examination
- Bimanual examination
- Speculum examination
What Ix would you like to perform?
- Bloods: FBC (iron deficient anaemia), TFT and clotting screen (If indicated by Hx)
- Transvaginal US: identification of abnormal structural uterine pathology, abnormality and ovarian assessment
- Endometrial assessment: biopsy (pipelle) or hysteroscopy (esp in younger women with persistent menorrhagia, irregular bleeding or endometrial Ca risk factors)
- Cervical smear: if due or appears suspicious on speculum
- Triple swabs: rule out infective cause/PID
Treatment: non hormonal options
NSAIDs Mefenamic acid
- Inhibit prostaglandin synthesis and reduce endometrial blood loss by ~25%
- May also treat dysmenorrhoea •Not if e.g. past history of a GI bleed, may cause N/V/D Antifibrinolytics
Tranexamic acid
- Inhibit plasminogen activator, increasing clot formation in the spiral arterioles
- Can reduce blood loss by ~50% •Side effects: GI, nausea, tinnitus
- Not suitable if predisposed to thromboembolism
Treatment: Hormonal options
Mirena (1st line Treatment )
- Delivers progestogen directly to uterus - highly effective contraceptive
- After 12 months, blood loss reduced by 95% but there is initially a high incidence of irregular bleeding
- Does not protect against STIs, may cause unscheduled bleeding, may cause pain
Combined OCP
- Reduces blood loss by ~50% 3rd line Treatment
Systemic progestogens
- E.g. norethisterone 5mg TDS PO
- Reduces blood loss by 80% by directly inhibiting ovulation and directly suppressing endometrium
Depot injectable progestogen
- Side effects: nausea, bloating, headache, breast tenderness, weight gain, acne
GnRH analogues
- Cause amenorrhoea
- Usually for short-term use only (max 6/12)
- Hot flushes, vaginal dryness, loss of bone mineral density with time
