Gestational hypertension


Hello: Seven years ago, I gave birth to a child, and at that time, I experienced severe edema due to high blood pressure, as well as a lack of amniotic fluid and placental abruption.
I underwent a cesarean section at 37 weeks.
The doctor advised me not to have any more children due to the high risk of recurrence.
I would like to understand more about this condition.
Thank you.

Dr. Lü Lizheng reply Obstetrics and Gynecology


Hello! Your condition is preeclampsia complicated by placental abruption, and the recurrence rate for your second pregnancy is approximately 10%.
It is recommended to engage in regular exercise to stabilize blood pressure, avoid greasy foods, and prevent vascular sclerosis, which can reduce the risk of recurrence.
Once pregnancy is confirmed, closely collaborate with your obstetrician to monitor blood pressure, which should help minimize the risks.
Sincerely, Dr.

More Info


Preeclampsia is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, often the kidneys. It typically occurs after the 20th week of pregnancy and can lead to severe complications for both the mother and the baby if not managed properly. Given your history of preeclampsia during your first pregnancy, it is understandable that you have concerns about the risks associated with future pregnancies.

Your previous experience with high blood pressure, severe edema (swelling), oligohydramnios (low amniotic fluid), and placental abruption (detachment of the placenta) places you at a higher risk for developing preeclampsia again in subsequent pregnancies. Studies indicate that women who have had preeclampsia in a previous pregnancy are at an increased risk of recurrence, with estimates suggesting that the recurrence rate can be as high as 25-50%.
The exact cause of preeclampsia is not fully understood, but it is believed to involve problems with the placenta, immune system, and blood vessels. Risk factors include a history of preeclampsia, chronic hypertension, obesity, diabetes, and certain genetic factors. Given your history, it is crucial to monitor your health closely in any future pregnancies.

Here are some considerations and recommendations for managing the risk of preeclampsia in future pregnancies:
1. Preconception Counseling: Before attempting to conceive again, it is advisable to have a thorough discussion with your healthcare provider. They can assess your overall health, review your medical history, and help you understand the risks involved.

2. Regular Monitoring: If you decide to become pregnant again, regular prenatal care is essential. Your healthcare provider may recommend more frequent check-ups to monitor your blood pressure and overall health.

3. Low-Dose Aspirin: Research has shown that low-dose aspirin (usually 81 mg daily) can reduce the risk of preeclampsia in women with a history of the condition. Discuss this option with your healthcare provider to see if it is appropriate for you.

4. Healthy Lifestyle: Maintaining a healthy lifestyle can help manage blood pressure and reduce the risk of complications. This includes a balanced diet, regular exercise, and avoiding smoking and excessive alcohol consumption.

5. Monitoring Symptoms: Be vigilant about recognizing the symptoms of preeclampsia, which can include high blood pressure, severe headaches, vision changes, abdominal pain, and sudden swelling of the hands and face. If you experience any of these symptoms, seek medical attention immediately.

6. Consideration of Delivery Timing: In cases of severe preeclampsia, early delivery may be necessary to protect the health of both mother and baby. Your healthcare provider will discuss the best timing for delivery based on your condition and the health of your baby.

7. Support and Resources: Consider joining support groups or seeking resources that provide information about preeclampsia and pregnancy. Organizations such as the Preeclampsia Foundation offer valuable information and support for women who have experienced this condition.

In summary, while your history of preeclampsia does increase the risk of recurrence in future pregnancies, proactive management and close monitoring can help mitigate these risks. It is essential to work closely with your healthcare provider to develop a personalized plan that addresses your specific health needs and concerns.
