Pregnancy-induced hypertension


Hello, doctor.
I previously inquired and am back for more assistance.
I am currently 35 weeks pregnant with a baby girl weighing 2237 grams.
Is this weight too small? Can high blood pressure affect the baby's growth? What should I do? My blood pressure is between 140-150 systolic and 90-100 diastolic.
Do I need to take blood pressure medication? The doctor previously prescribed Hydralazine, but it didn't seem effective for my blood pressure.
This time, I was prescribed Hydralazine again; will this have any side effects on the baby? Also, is Amlodipine the same as Betaloc? The medication bag says Betaloc, but when I looked it up online, it showed Amlodipine.
Will taking this cause any issues? I'm very worried.

Dear Yaling,
1.
A female baby at 35 weeks weighing 2,237 grams is not considered small.
2.
High blood pressure does not necessarily cause the baby to be underweight; it depends on placental function.
Doppler ultrasound can be performed to assess placental function.
3.
For medication use, please discuss directly with your physician.
Wishing you safety and health,
Dr.

Managing high blood pressure during pregnancy is a critical concern for both the mother and the developing fetus. High blood pressure, or hypertension, can lead to various complications, including preeclampsia, placental abruption, and fetal growth restriction. In your case, at 35 weeks of pregnancy, your concern about the baby's weight and the implications of your blood pressure readings is valid.

Firstly, regarding your baby's weight of 2237 grams, it is essential to understand that fetal growth can vary significantly among individuals. While this weight may be on the lower side, it is not uncommon for babies to be smaller, especially if there are underlying factors such as maternal hypertension. The growth of the fetus can be influenced by the mother's health, including her blood pressure levels. High blood pressure can restrict blood flow to the placenta, which may affect the nutrients and oxygen the baby receives, potentially leading to slower growth.

To address your blood pressure readings of 140-150 systolic and 90-100 diastolic, it is crucial to monitor these levels closely. While these readings indicate hypertension, the decision to start or continue medication should be made in consultation with your healthcare provider. Medications like hydralazine are often prescribed to manage high blood pressure during pregnancy, and while they can be effective, it is essential to discuss any potential side effects with your doctor. Hydralazine is generally considered safe for use during pregnancy, but like any medication, it can have side effects, and monitoring is necessary.

You mentioned that your previous medication, labetalol (哈伯寧), seemed ineffective. It is not uncommon for different medications to have varying effects on individuals, and sometimes adjustments are necessary to find the right treatment. Hydralazine works by relaxing blood vessels, which can help lower blood pressure, but it is essential to ensure that it is suitable for your specific situation.

Regarding the confusion between "壓平利淨錠" (Amlodipine) and "血得平" (which is likely referring to a brand name for a similar medication), it is crucial to clarify this with your healthcare provider or pharmacist. Both medications may belong to the same class of drugs (calcium channel blockers), but they can have different formulations and effects. Always ensure you understand what medication you are taking and its potential implications for your pregnancy.

In managing high blood pressure during pregnancy, lifestyle modifications can also play a significant role. These include:
1. Diet: A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help manage blood pressure. Reducing salt intake is also beneficial.

2. Hydration: Staying well-hydrated can support overall health and may help with blood pressure regulation.

3. Rest and Stress Management: Adequate rest and stress-reducing techniques such as prenatal yoga or meditation can help manage blood pressure levels.

4. Regular Monitoring: Keeping track of your blood pressure at home and attending regular prenatal check-ups is essential for monitoring your health and your baby's development.

5. Communication with Healthcare Providers: Always keep an open line of communication with your healthcare team. Discuss any concerns or side effects you experience with your medications.

In conclusion, while high blood pressure during pregnancy poses risks, with careful management and monitoring, many women can have healthy pregnancies and deliver healthy babies. It is crucial to work closely with your healthcare provider to tailor a treatment plan that is safe and effective for you and your baby. If you have any concerns about your medications or your baby's growth, do not hesitate to reach out to your healthcare provider for guidance.
