MEDICAL TERMS IN OBSTETRICS AND GYNAECOLOGY

Abortion A way of ending a pregnancy using either medicines (medical abortion) or a surgical operation (surgical abortion).
Amniocentesis A procedure to take a sample of the fluid surrounding a baby in the womb. It can be carried out after the 15th week of pregnancy, by inserting a needle through the abdomen into the womb. It can be used to detect the presence of conditions such as Down syndrome.
Amniotic fluid The watery liquid surrounding and protecting the growing fetus in the uterus.
Anaemia Anaemia is when the level of haemoglobin in your blood is lower than normal; it can be mild or severe. Anaemia can cause tiredness, breathlessness, fainting, headaches and your heart to beat faster.
Anaesthesia A form of pain relief.
Antenatal Before birth.

 

Bacteria Organisms (so small that they are can only be seen through a microscope) that may cause certain kinds of infection.
Bacterial vaginosis (BV) A very common vaginal infection which is caused by an imbalance in the types of bacteria in the vagina. It causes discharge and soreness. BV is not sexually transmitted. It does not affect men.
Bicornuate uterus (womb) A uterus resembling a heart-shape (rather than the usual pear-shape).
Biopsy A procedure to take a small sample of tissue from some part of the body for examination.
Bladder The organ in the pelvis which expands to store urine and contracts to pass it out through the urethra.
Blood group Your blood group is determined by the presence of chemical markers (known as antigens or proteins), on the surface of your red blood cells. Group A blood has A antigens, Group B blood has B antigens, Group AB blood has both A and B antigens and Group O blood has no antigens on the red blood cells.
Breech position When the baby is lying bottom first in the womb.
Caesarean delivery An operation to deliver the baby by cutting through the wall of the abdomen and the uterus. It may be done as a planned (elective) or an emergency procedure.

Cervix The entrance or neck of the womb, at the top of the vagina.
Chocolate cysts Cysts which form on the ovaries in some women who have endometriosis.
Chromosomes The genetic structures within cells which contain our DNA (the material that carries genetic information). A normal cell contains 46 chromosomes.
Chronic Something that persists or continues for at least six months.
Complete miscarriage When all the pregnancy tissue has been passed and the uterus is empty.
Conception A process which begins with fertilisation of an egg by sperm and ends with successful implantation of the embryo.
Contraception Prevention of pregnancy.

 

Dilatation and curettage (D&C) A small operation which opens the entrance of the womb (the cervix) in order to remove tissue from the lining of the womb (the endometrium).
Delivery Birth of a baby and its afterbirth. A baby may be delivered through the vagina or by Caesarean section.

Menstrual cycle The process by which an egg develops each month and the lining of the womb is prepared for possible pregnancy. If the egg is not fertilised, it is reabsorbed back into the body and the lining of the womb (the endometrium) is shed (this is what is known as a period or menstruation) and the cycle begins again. The cycle is controlled by hormones. On average a cycle lasts 28 days. Some women have shorter cycles, some have longer ones.
   
   
Neonatalologist A doctor who specialises in caring for newborn babies.
   
   
Obstetrician A doctor who specialises in the care of pregnant women.
