Gestational hypertension, also referred to as pregnancy-induced hypertension (PIH), is a condition marked by elevated blood pressure during pregnancy. This condition can lead to serious complications such as preeclampsia, which is also known as toxemia. Approximately 6 to 8% of pregnant women experience gestational hypertension.
Types of Hypertension During Pregnancy
High blood pressure can manifest in various ways during pregnancy, and there are three common types to be aware of:
- Chronic Hypertension – This occurs when women have high blood pressure (140/90 mmHg or higher) before pregnancy, early in pregnancy (before 20 weeks), or continue to experience it after childbirth.
- Gestational Hypertension – This type develops after the 20th week of pregnancy and typically resolves after delivery.
- Preeclampsia – This severe condition may arise from either gestational or chronic hypertension after the 20-week mark. Symptoms include high blood pressure and protein in the urine, which can lead to serious complications for both the mother and baby if not treated promptly.
Risk Factors for Gestational Hypertension
Certain women may be at a higher risk of developing gestational hypertension, including:
- First-time mothers
- Women with a family history of PIH
- Those expecting multiples
- Women under 20 or over 40 years old
- Individuals with a history of high blood pressure or kidney disease prior to pregnancy
Identifying Gestational Hypertension
During each prenatal visit, your healthcare provider will monitor your blood pressure and urine levels. Additionally, they may evaluate kidney function and blood coagulation, order blood tests, perform ultrasounds to assess fetal growth, and utilize Doppler ultrasound to measure blood flow to the placenta.
Treatment Options for Gestational Hypertension
The treatment approach depends on your proximity to your due date. If you are close to delivery and the baby is sufficiently developed, your doctor may recommend an early delivery. For mild hypertension when the baby is not fully developed, your healthcare provider might suggest:
- Resting on your left side to alleviate pressure on major blood vessels
- Increasing the frequency of prenatal check-ups
- Reducing salt intake
- Drinking at least eight glasses of water daily
In cases of severe hypertension, medication may be prescribed to manage blood pressure until a safe delivery can occur.
Impact on Your Baby
Gestational hypertension can restrict blood flow to the placenta, potentially depriving your baby of essential oxygen and nutrients, leading to low birth weight. However, if detected and managed early, most women can still deliver healthy babies. Severe cases may escalate to preeclampsia, which poses greater risks for both mother and child.
Preventing Gestational Hypertension
Currently, there is no guaranteed way to prevent gestational hypertension. While some contributing factors can be managed, others cannot. To mitigate risks, follow your doctor’s advice regarding diet and exercise. Helpful suggestions for prevention include:
- Using salt sparingly, according to taste
- Staying hydrated with at least eight glasses of water daily
- Increasing protein intake while limiting fried and junk food
- Ensuring adequate rest
- Engaging in regular exercise
- Elevating your feet several times a day
- Avoiding alcohol and caffeine
Your doctor may also recommend prescribed medications and additional supplements.
