Gestational diabetes increases the risk of vascular endothelial dysfunction and inflammation, which contribute to the development of preeclampsia. Both conditions share pathophysiological mechanisms, such as insulin resistance and abnormal placental perfusion, leading to hypertension and proteinuria in the mother. Recognizing preeclampsia as a common complication is critical for timely surveillance and management to prevent adverse maternal and fetal outcomes.
