Growth restriction observed at less than 28 weeks gestation is classified as symmetrical growth restriction. This type of growth restriction implies that the fetal growth is uniformly affected, indicating that both the fetal head and body are proportionately smaller. Symmetrical growth restriction is often associated with intrinsic factors or early placental dysfunction that affects the fetus's overall growth.

In cases where growth restriction occurs before 28 weeks, which is considered before the third trimester, it generally indicates a more severe issue because this is a time when the fetus is still developing critical organ systems. The fact that the restriction is symmetrical suggests that the problem occurred early in the pregnancy, affecting the overall development of the fetus rather than just certain parts of the body.

Other forms of growth restriction, such as asymmetrical growth restriction, typically occur later in pregnancy, leading to a situation where the head might grow normally while the body is smaller. Understanding these distinctions is crucial for assessing fetal health and planning appropriate interventions.
