Miscarriage is the most common complication of pregnancy, affecting 12-24% of all pregnancies
Most early miscarriages are caused by chromosomal abnormalities, and the risk of miscarriage increases with maternal age
Transvaginal ultrasound is the best way to diagnose miscarriage
Most miscarriages resolve spontaneously and expectant management should be offered as the first line management strategy
Emergency surgery is indicated in women presenting with severe pain or bleeding and in those with signs of infection
Offer women and their partners access to counselling services, leaflets, web addresses, and helpline numbers for support organisations

The loss of a pregnancy is often distressing for women and their partners, with adverse effects on their social and psychological wellbeing.
Reported UK maternal mortality rates after miscarriage in the period 1985 to 2008 range from 0.05 to 0.22 per 100 000 maternities.4 The most common causes of death were haemorrhage and sepsis, which tended to occur more often after second trimester losses.
Women with miscarriages are often treated conservatively in an outpatient setting, and general practitioners are often asked to advise women on the management options available to them and to provide support during follow-up. The aim of this review is to describe the diagnosis and …
