What is a major consequence of maternal hypotension during pregnancy?

Maternal hypotension during pregnancy can significantly impact the circulation of blood to the placenta, which directly affects fetal well-being. When blood pressure decreases, the body's ability to perfuse the uterus and placenta diminishes, leading to decreased uteroplacental blood flow. This reduction means that the fetus may not receive adequate oxygen and nutrients, which are critical for healthy development. Insufficient blood flow can lead to various complications, such as impaired fetal growth, potential fetal distress, or even stillbirth in severe cases. Thus, the major consequence of maternal hypotension is indeed a decreased uteroplacental blood flow, which has important implications for the health of both the mother and the fetus.
