Hypertension is also sub-classified: Isolated systolic hypertension refers to elevated systolic pressure with normal diastolic pressure and is common in the elderly. Hypertension is classified as "resistant" if medications do not reduce blood pressure to normal levels.
Print Overview Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. Preeclampsia usually begins after 20 weeks of pregnancy in women whose blood pressure had been normal.
Left untreated, preeclampsia can lead to serious — even fatal — complications for both you and your baby.
If you have preeclampsia, the most effective treatment is delivery of your baby. Even after delivering the baby, it can still take a while for you to get better.
If you're diagnosed with preeclampsia too early in your pregnancy to deliver your baby, you and your doctor face a challenging task.
Your baby needs more time to mature, but you need to avoid putting yourself or your baby at risk of serious complications. Rarely, preeclampsia develops after delivery of a baby, a condition known as postpartum preeclampsia.
Symptoms Preeclampsia sometimes develops without any symptoms.
High blood pressure may develop slowly, or it may have a sudden onset. Monitoring your blood pressure is an important part of prenatal care because the first sign of preeclampsia is commonly a rise in blood pressure. Other signs and symptoms of preeclampsia may include: Excess protein in your urine proteinuria or additional signs of kidney problems Severe headaches Changes in vision, including temporary loss of vision, blurred vision or light sensitivity Upper abdominal pain, usually under your ribs on the right side Nausea or vomiting Decreased levels of platelets in your blood thrombocytopenia Impaired liver function Shortness of breath, caused by fluid in your lungs Sudden weight gain and swelling edema — particularly in your face and hands — may occur with preeclampsia.
But these also occur in many normal pregnancies, so they're not considered reliable signs of preeclampsia. When to see a doctor Make sure you attend your prenatal visits so that your care provider can monitor your blood pressure.
Contact your doctor immediately or go to an emergency room if you have severe headaches, blurred vision or other visual disturbance, severe pain in your abdomen, or severe shortness of breath. Because headaches, nausea, and aches and pains are common pregnancy complaints, it's difficult to know when new symptoms are simply part of being pregnant and when they may indicate a serious problem — especially if it's your first pregnancy.
If you're concerned about your symptoms, contact your doctor. Request an Appointment at Mayo Clinic Causes The exact cause of preeclampsia involves several factors.
Experts believe it begins in the placenta — the organ that nourishes the fetus throughout pregnancy. Early in pregnancy, new blood vessels develop and evolve to efficiently send blood to the placenta.
