High Blood Pressure In Pregnancy Linked To Later Health Risks

[Natural Health]-How to Lower Your High Blood Pressure During Pregnancy?

Women with slightly elevated blood pressure during pregnancy could be more likely to develop so-called metabolic syndrome later, Chinese researchers say.

Metabolic syndrome – a combination of traits and symptoms such as abdominal fat and high blood sugar – is a strong predictor of heart disease and diabetes. So blood pressure at the high end of normal in pregnancy could be an early warning sign, according to the study authors.

The optimal blood pressure levels in pregnant women remain an open question, said lead author Dr. Jian-Min Niu of Guangdong Women and Children Hospital in Guangzhou.

In general, healthy blood pressure usually falls at or below 120/80 mmHg, Niu said. The threshold for high blood pressure, or hypertension, is 140/90 or greater. The range between healthy and high blood pressure is sometimes called prehypertension because readings at the high end of normal may be a stage on the way to full-fledged hypertension.

In many countries, every pregnant woman has at least 10 routine checkups, Niu told Reuters Health by email. However, they will not be informed of risk unless the blood pressure level is at or greater than 140/90 mmHg.

The researchers studied 506 pregnant women with no history of high blood pressure or symptoms of diabetes, measuring their blood pressure, weight and other health metrics several times during pregnancy and for up to a year and a half after they gave birth.

What Is Considered High Blood Pressure During Pregnancy

A blood pressure that is greater than 130/90 mm Hg or that is 15 degrees higher on the top number from where you started before pregnancy may be cause for concern.

High blood pressure during pregnancy is defined as 140 mm Hg or higher systolic, with diastolic 90 mm Hg or higher.

Early in pregnancy, usually from 5 weeks to the middle of the second trimester, a pregnant womans blood pressure may actually decrease. This is because pregnancy hormones can stimulate blood vessels to widen. As a result, the resistance to blood flow isnt as high.

Is It Safer To Deliver A Baby Immediately Or Wait If The Mother Has High Blood Pressure After 34 Weeks Of Pregnancy That Is Not Persistently Severe

What is the issue?

Women who have high blood pressure during pregnancy or who develop pre-eclampsia can develop serious complications. Potential complications for the mother are worsening of pre-eclampsia, development of seizures and eclampsia, HELLP syndrome , detachment of the placenta, liver failure, renal failure, and difficulty breathing because of fluid in the lungs.

Delivering the baby usually stops the mothers high blood pressure from getting worse, but a baby who is born prematurely may have other health problems, such as difficulty breathing, because the lungs are still immature. Induction of labour can lead to overstimulation of contractions and fetal distress. The alternative is waiting to deliver the baby while closely monitoring both the mother and her baby.

Why is this important?

As there are both benefits and risks to planned early delivery compared with waiting when the mother has high blood pressure toward the end of pregnancy, we wanted to know which is the safest option. We looked for clinical trials that compared planned early delivery, by induction of labour or by caesarean section, with a policy of delayed delivery of the baby.

What evidence did we find?

No studies attempted to blind the women or their clinicians to which group they were in. Women and staff were aware of the intervention and this may have affected aspects of care and decision-making. Most of the evidence was of moderate quality, so we can be moderately certain about the findings.

Does Blood Pressure Remain High After The Birth

High blood pressure in pregnancy usually disappears once the baby is born. However, there may still be some complications during the first few days after the birth and you will need to be monitored carefully for several weeks.

Who Is At Risk For Preeclampsia

Am I Predisposed To Develop Preeclampsia

Preeclampsia is high blood pressure that occurs exclusively in pregnancy. Therefore, even if your chronic high blood pressure is under control before you are pregnant, you may later develop preeclampsia, as well. If you have chronic hypertension, you are more likely to develop preeclampsia, but it does not necessarily mean you will. Also, should you develop preeclampsia, your doctor may recommend inducing labor before your due date to prevent further pregnancy complications. If the preeclampsia is severe, your doctor may recommend a cesarean birth.

  • Hemolysis, or the breaking down of red blood cells
  • Elevated Liver enzymes, which is a sign of liver damage
  • Low Platelet count; platelets are a material that forms blood clots

Other complications associated with high blood pressure during pregnancy include:

  • stroke
  • placental abruption, a serious medical condition in which the placenta separates from the wall of the uterus too early

Changes In Blood Pressure During Pregnancy

As a woman progresses in her pregnancy, her blood pressure may change or return to pre-pregnancy levels. There are a few possible reasons for this.

The amount of blood in a womans body increases. According to the journal Circulation, a womans blood volume increases by as much as 45 percent during pregnancy. This is extra blood that the heart must pump throughout the body.

The left ventricle becomes thicker and larger. This temporary effect allows the heart to work harder to support the increased blood volume.

The kidneys release increased amounts of vasopressin, a hormone that leads to increased water retention.

In most cases, high blood pressure during pregnancy will decrease after the baby is delivered. In cases where blood pressure remains elevated, your doctor may prescribe medication to get it back to normal.

What Are Possible Complications Of High Blood Pressure In Pregnancy

High blood pressure taxes the blood vessels, which in turn decreases blood flow to the liver, kidneys, brain, heart, lungs, uterus and placenta. When gestational hypertension isnt under control and the placenta isnt getting enough blood, fewer nutrients and oxygen make it to your baby, which can slow fetal growth.

And if gestational hypertension morphs into preeclampsia, premature delivery or placental abruption can occur, which is the too-early separation of the placenta from the uterus. In the worst of cases, stillbirth and eclampsia are possible. Untreated very high blood pressure can also lead to stroke.

High Blood Pressure And Gestation

High blood pressure may increase your risk of complications during pregnancy.

You can have hypertension in pregnancy either as a continuation of a chronic problem that you had before you were pregnant or as a new problem that develops during your pregnancy, which is called gestational hypertension or preeclampsia.

Hypertensive disorders occur in 6% to 8% of pregnancies around the world, and about a quarter of hospital admissions for mothers during their pregnancy.
