Obstetrics and gynaecology is concerned with the care of pregnant woman, her unborn child and the management of diseases specific to women. The specialty combines medicine and surgery. Most consultants within the specialty work in both obstetrics and gynaecology (O&G). Many have a major special interest in a particular area, such as high-risk obstetrics, fertility care or minimal access surgery. A smaller number of consultants work as sub specialists, with all of their work concentrated in a specific area of practice.
