Hypertension during pregnancy can lead to various complications. Preeclampsia, characterised by high blood pressure and signs of organ damage, can cause kidney problems, liver abnormalities, and low blood platelet count. It poses risks to both the mother and baby, including preterm birth, low birth weight, and intrauterine growth restriction. Hypertension can also lead to placental abruption, respiratory distress syndrome, and developmental issues for the baby. Close monitoring and medical care are essential to manage these risks and ensure a healthy pregnancy.
