Overview
Plain-Language Overview
HELLP syndrome is a serious pregnancy complication that affects the liver and blood. It usually occurs in the later stages of pregnancy or shortly after delivery. The condition involves breakdown of red blood cells, liver damage, and a low number of platelets, which are cells that help blood clot. These changes can cause symptoms like pain in the upper right abdomen, nausea, and fatigue. HELLP syndrome can be dangerous for both the mother and baby if not recognized and treated promptly.
Clinical Definition
HELLP syndrome is a severe form of preeclampsia characterized by Hemolysis, Elevated Liver enzymes, and Low Platelet count. It results from abnormal placental development leading to systemic endothelial dysfunction, microangiopathic hemolytic anemia, and hepatic injury. The syndrome typically presents in the third trimester or postpartum and is associated with significant maternal morbidity including liver hematoma, disseminated intravascular coagulation, and renal failure. The pathophysiology involves widespread microvascular damage and platelet activation causing thrombocytopenia and hepatic ischemia. Early recognition is critical due to the risk of rapid clinical deterioration.
