A high-risk pregnancy means a pregnancy in which there is a risk to the woman or the baby.
The German Society for Perinatal Medicine outlines such risk factors that carry a risk:
- pregnancy-induced hypertension;
- pregnancy transmission;
- haemolytic disease of the fetus;
- diabetes;
- preterm delivery;
- woman's age under 15 or over 40;
- organ diseases: heart, cardiovascular, lung, liver, kidney, thyroid;
- anaemia of the pregnant woman;
- abnormal position of the baby;
- obesity of the pregnant woman;
- abnormal size of the uterus in relation to the age of pregnancy;
- infectious diseases: syphilis, tuberculosis, aids, herpes, viral diseases;
- bleeding;
- multiple pregnancy;
- serological conflict;
- pre-eclampsia.
In pregnant women whose pregnancy is a risk to mother and baby, additional tests are performed to give more accurate information.
