P05: Slow fetal growth and fetal malnutrition

P05.9: Slow fetal growth, unspecified

While in the womb, the child is supplied with oxygen and nutrients from the mother’s blood. The placenta forms in the mother’s womb during pregnancy. The placenta consists of cells from the mother and cells from the unborn child. The umbilical cord connects the child to the placenta.

If the child is not adequately nourished in the womb, it may be too light or too small at birth, for example. There can be different reasons why the child is not adequately nourished in the womb. For example, that occurs with particular diseases of the mother or if the placenta is not working properly. Sometimes the placenta also no longer works properly at the end of the pregnancy. The child may also receive inadequate nourishment in the womb if the mother smokes.
