<s>[INST] context: Source: style="font-family: Times New Roman, Times, serif"> What is pregnancy-induced hypertension (PIH)?Pregnancy-induced hypertension (PIH) is a form of high blood pressure in pregnancy. It occurs in about 7 to 10 percent of all pregnancies. Another type of high blood pressure is chronic hypertension - high blood pressure that is present before pregnancy begins.Pregnancy-induced hypertension is also called toxemia or preeclampsia. It occurs most often in young women with a first pregnancy. It is more common in twin pregnancies, and in women who had PIH in a previous pregnancy.Usually, there are three primary characteristics of this condition, including the following:high blood pressure (a blood pressure reading higher than 140/90 mm Hg or a significant increase in one or both pressures)protein in the urineedema (swelling)Eclampsia is a severe form of pregnancy-induced hypertension. Women with eclampsia have seizures resulting from the condition. Eclampsia occurs in about one in 1,600 pregnancies and develops near the end of pregnancy, in most cases.HELLP syndrome is a complication of severe preeclampsia or eclampsia. HELLP syndrome is a group of physical changes including the breakdown of red blood cells, changes in the liver, and low platelets (cells found in the blood that are needed to help the blood to clot in order to control bleeding).What causes pregnancy-induced hypertension (PIH)?The cause of PIH is unknown. Some conditions may increase the risk of developing PIH, including the following:pre-existing hypertension (high blood pressure)kidney diseasediabetesPIH with a previous pregnancymother's age younger than 20 or older than 40multiple fetuses (twins, triplets)Why is pregnancy-induced hypertension a concern?With high blood pressure, there is an increase in the resistance of blood vessels. This may hinder blood flow in many different organ systems in the expectant mother including the liver, kidneys, brain, uterus, and placenta.There are other problems that may develop as a result of PIH. Placental abruption (premature detachment of the placenta from the uterus) may occur in some pregnancies. PIH can also lead to fetal problems including intrauterine growth restriction (poor fetal growth) and stillbirth.If untreated, severe PIH may cause dangerous seizures and even death in the mother and fetus. Because of these risks, it may be necessary for the baby to be delivered early, before 37 weeks gestation.What are the symptoms of pregnancy-induced hypertension?The following are the most common symptoms of high blood pressure in pregnancy. However, each woman may experience symptoms differently. Symptoms may include:increased blood pressureprotein in the urineedema (swelling)sudden weight gainvisual changes such as blurred or double visionnausea, vomitingright-sided upper abdominal pain or pain around the stomachurinating small amountschanges in liver or kidney function testsHow is pregnancy-induced hypertension diagnosed?Diagnosis is often based on the increase in blood pressure levels, but other symptoms may help establish PIH as the diagnosis. Tests for pregnancy-induced hypertension may include the following:blood pressure measurementurine testingassessment of edemafrequent weight measurementseye examination to check for retinal changesliver and kidney function testsblood clotting testsTreatment for pregnancy-induced hypertension:Specific treatment for pregnancy-induced hypertension will be determined by your physician based on:your pregnancy, overall health and medical historyextent of the diseaseyour tolerance for specific medications, procedures, or therapiesexpectations for the course of the diseaseyour opinion or preferenceThe goal of treatment is to prevent the condition from becoming worse and to prevent it from causing other complications. Treatment for pregnancy-induced hypertension (PIH) may include:bedrest (either at home or in the hospital may be recommended).hospitalization (as specialized personnel and equipment may be necessary).magnesium sulfate (or other antihypertensive medications for PIH).fetal monitoring (to check the health of the fetus when the mother has PIH) may include:fetal movement counting - keeping track of fetal kicks and movements. A change in the number or frequency may mean the fetus is under stress.nonstress testing - a test that measures the fetal heart rate in response to the fetus' movements.biophysical profile - a test that combines nonstress test with ultrasound to observe the fetus.Doppler flow studies - type of ultrasound that uses sound waves to measure the flow of blood through a blood vessel.continued laboratory testing of urine and blood (for changes that may signal worsening of PIH).medications, called corticosteroids, that may help mature the lungs of the fetus (lung immaturity is a major problem of premature babies).delivery of the baby (if treatments do not control PIH or if the fetus or mother is in danger). Cesarean delivery may be recommended, in some cases.Prevention of pregnancy-induced hypertension:Early identification of women at risk for pregnancy-induced hypertension may help prevent some complications of the disease. Education about the warning symptoms is also important because early recognition may help women receive treatment and prevent worsening of the disease.
