In some women, high blood pressure occurs only while pregnant. If high blood pressure occurs in the second half of pregnancy, it is known as gestational hypertension. This type of blood pressure goes away after the baby is born. If gestational hypertension is accompanied by other findings (protein loss in the urine, proteinuria, swelling in the feet, namely edema), it is called preeclampsia.

Pregnancy-induced hypertension (high blood pressure) only occurs when you are pregnant. With pregnancy hypertension, the systolic pressure (the first digit) rises by more than 140 ml or is more than 30 ml above your normal blood pressure.
A diastolic reading (second digit) of 90 ml or your normal blood pressure above 15 ml indicates a problem. For example, a woman's blood pressure is 100/60 at the beginning of pregnancy. At the end of her pregnancy, it is 130/90. This is high blood pressure in the blood. or preeclampsia.

Your doctor will check your blood pressure at each prenatal visit to determine if it has risen to a serious level.

Preeclampsia occurs in 10% of pregnant women and if left untreated, it can cause permanent damage to the mother's nervous system, blood vessels or kidneys; in the baby, it may cause growth retardation (because the amount of blood passing through the placenta is reduced) or oxygen deprivation.

What is preeclampsia?

Preeclampsia describes various symptoms that occur only during pregnancy or shortly after birth.

Preeclampsia symptoms

  • Sudden excessive weight gain and Swelling (edema)
  • Protein in the urine (proteinuria)
  • High blood pressure (hypertension)
  • Increased reflexes (hyperreflexia)

Other important symptoms about blood pressure during pregnancy, which are not seen in everyone, are pain on the right side under the ribs, headache, visual impairment. These are all warning signs. Especially if you have high blood pressure problems during pregnancy, report these symptoms to your doctor immediately.
Most pregnant women experience swelling. Swelling in the legs alone does not mean you have preeclampsia. It is also possible to have high blood pressure while pregnant without preeclampsia.


It is not known for certain what causes preeclampsia or eclampsia.
