High-Risk Pregnancy Care

What is a High-Risk Pregnancy?

A high-risk pregnancy is when the mother, the baby, or both are at a higher risk of health problems during pregnancy, delivery, or after birth. High-risk pregnancies require closer monitoring and care, often with more frequent visits to an obstetrician and sometimes referral to a specialist in maternal-foetal medicine.

How Common is High-Risk Pregnancy?

The prevalence of high-risk pregnancies can vary significantly depending on the definition of "high-risk" and the population being studied. Many pregnancies can involve at least one minor complication, but significant or severe complications that elevate a pregnancy to high-risk status occur in a smaller percentage.

What is High-Risk Pregnancy Care?

High-risk pregnancy care refers to the specialised medical care provided to women with potential complications that could affect their pregnancy, themselves, or their baby. These complications might arise due to various reasons, including maternal age, existing health conditions (like heart disease, diabetes, and high blood pressure), pregnancy complications (like preeclampsia), lifestyle factors (like smoking and alcohol), and complications related to the baby's health. High-risk pregnancies require management by specialists to ensure the best possible outcomes for the mother and baby.

Who is Suitable for High-Risk Pregnancy Care?

A woman might be suitable for high-risk pregnancy care if she falls into one or more of the following categories:

  • Advanced maternal age: Pregnant women over 35 are often considered high-risk.
  • Multiple pregnancies: Pregnancies involving twins, triplets, or more can often be classified as high-risk.
  • Pre-existing medical conditions: Diabetes, high blood pressure, kidney disease, autoimmune diseases, or HIV/AIDS can make a pregnancy high-risk.
  • Pregnancy complications: Conditions that occur during pregnancy, like gestational diabetes, preeclampsia, or problems with the placenta, can lead to a high-risk pregnancy.
  • Lifestyle factors: Smoking, alcohol, and illegal drug use can increase the risk of complications during pregnancy.
  • Obstetric history: Women with complications in previous pregnancies, such as preterm labour, preeclampsia, or caesarean section, may require high-risk pregnancy care.

Importance of High-Risk Pregnancy Care

High-risk pregnancy care is essential for the well-being of both the mother and the unborn child. This specialised care focuses on addressing and managing the potential risks and complications that could occur during pregnancy, birth, or post-delivery. Here are some key reasons why high-risk pregnancy care is crucial:

  • Early Detection of Complications: Regular monitoring and specialised tests can help detect complications such as gestational diabetes, preeclampsia, or foetal growth problems early. Early detection allows for prompt management, preventing conditions from worsening and mitigating potential harm to the mother and baby.
  • Management of Existing Health Conditions: If a pregnant woman has pre-existing conditions like diabetes, hypertension, or kidney disease, high-risk pregnancy care ensures these are well-managed to avoid any adverse effects on the pregnancy.
  • Guidance and Counseling: High-risk pregnancy care includes providing guidance and counselling to parents-to-be. This helps them understand the complexities of their situation, empowers them to make informed decisions, and assists in managing their stress and anxiety related to the high-risk nature of the pregnancy.
  • Specialised Care: A high-risk pregnancy often needs care beyond standard prenatal services. This can include consultations with maternal-foetal medicine specialists, advanced imaging techniques, genetic counselling, and access to a higher level of neonatal care if necessary.
  • Planning for Delivery: In a high-risk pregnancy, planning the timing and mode of delivery is crucial to minimise risks to the mother and baby. For example, certain conditions might require a planned caesarean section or induction of labour at an earlier gestational age.
  • Postnatal Care: After birth, high-risk pregnancy care continues closely monitoring both mother and baby to ensure any post-delivery complications are addressed swiftly.

The importance of high-risk pregnancy care lies in its potential to significantly improve the outcomes for both mother and baby by minimising risks, managing complications, and providing specialised care. It's a comprehensive, multidimensional approach to prenatal care to ensure the best possible results in challenging circumstances.

Potential Complications of High-Risk Pregnancy

At Dr Adham’s clinic, we take care of many high-risk pregnancies. There are a variety of different conditions that qualify as a high-risk pregnancy.

Most pregnancy complications can easily be detected and prevented during regular prenatal visits. The most common complications that arise during pregnancy are

  • morning sickness
  • bleeding in pregnancy
  • chicken pox exposure 
  • listeria 
  • anaemia and iron deficiency 
  • flu and Covid-19 
  • vitamin deficiency
  • travel in pregnancy
  • Parvovirus B19
  • preeclampsia
  • diabetes in pregnancy (gestational diabetes)

Morning Sickness

Morning sickness, characterised by nausea and vomiting, is a common early pregnancy symptom, often starting around the 6th week of gestation and typically subsiding by the 12th to 14th week. It can occur any time of the day, despite its name. Eating small, frequent meals and avoiding triggers may help manage symptoms.

Bleeding in Pregnancy

Any bleeding during pregnancy should be reported to an obstetrician immediately. Although it can occur for various reasons, including implantation in early pregnancy or changes in the cervix, it can also indicate serious complications like a miscarriage or placental issues.

Chicken Pox Exposure

Chickenpox exposure during pregnancy can be serious as it may lead to congenital varicella syndrome in the baby. You are generally protected if you've been vaccinated or have had chickenpox before. If not, contact your obstetrician immediately after exposure.

Listeria

Listeriosis is a foodborne illness that pregnant women are particularly susceptible to. It can lead to miscarriage, stillbirth, or severe illness in newborns. Pregnant women should avoid raw or undercooked meats, unpasteurised dairy products, and ready-to-eat deli meats to reduce the risk.

Anaemia and Iron Deficiency

Pregnancy increases the demand for iron in the body, which can lead to anaemia if unmet. Iron supplements are often recommended during pregnancy to prevent this.

Flu and COVID 

The flu vaccine is recommended for pregnant women as they are at higher risk for complications. Pregnant women are also at an increased risk of severe illness from COVID-19 and should get vaccinated unless contraindicated.

Vitamin Deficiency

Prenatal vitamins are essential for covering any nutritional gaps in the mother's diet. Vitamin K is crucial for blood clotting and is given to newborns to prevent a rare but serious bleeding disorder.

Travel in Pregnancy

Travelling, particularly air travel, is generally safe for pregnant women until the last month. However, certain high-risk pregnancies may require more caution.

Parvovirus B19 (Fifth Disease)

Parvovirus B19, also known as Fifth Disease, is a viral illness especially common in children. While it usually causes a mild rash illness, it can be more severe for some individuals, including pregnant women. The concern with Parvovirus B19 during pregnancy is that the virus can cross the placenta and infect the foetus.

For most pregnant women who become infected with parvovirus B19, the infection does not pose a risk for either the woman or her baby. However, in some cases, parvovirus B19 infection can lead to severe anaemia in the foetus. If exposed, contact your obstetrician immediately.

Preeclampsia

Preeclampsia is a serious condition characterised by high blood pressure and damage to organs like the liver and kidneys in pregnant women. It usually starts after 20 weeks of pregnancy in women with normal blood pressure.

Diabetes in Pregnancy (Gestational Diabetes)

Gestational diabetes is a type of diabetes that develops during pregnancy and usually resolves after delivery. It must be managed to avoid complications like high birth weight babies and preterm labour. Women with pre-existing diabetes should work with their obstetrician to optimise control during pregnancy.

High-Risk Pregnancy Management

Managing a high-risk pregnancy varies depending on the specific risks and complications associated with the pregnancy. Here are some general strategies:

  • Regular Prenatal Care: Frequent visits allow obstetricians to closely monitor the mother and baby and take early action if problems occur.
  • Specialist Consultation: Consult a maternal-foetal medicine specialist, genetic counsellor, or other specialists as needed.
  • Lifestyle Changes: Eating a healthy diet, maintaining an appropriate weight, regular physical activity (as advised by the obstetrician), and avoiding harmful substances (like alcohol, tobacco, and illicit drugs) are crucial.
  • Medication or Therapy: Certain conditions may need to be managed with medication or other therapies. For instance, gestational diabetes often requires dietary changes and sometimes medication to control blood sugar levels.
  • Hospitalisation: In some cases, hospitalisation might be necessary for close monitoring and care.
  • Delivery Planning: The timing and method of delivery need to be planned based on the mother's and baby's health.

High-Risk Pregnancy Prevention

While not all high-risk pregnancies can be prevented, some steps can help minimise risks:

  • Preconception Appointment: If you plan to get pregnant, meet with your obstetrician to discuss potential risks and ways to manage them.
  • Healthy Lifestyle: Maintain a healthy weight, eat a balanced diet, exercise regularly, and avoid harmful substances.
  • Regular Prenatal Care: Regular prenatal visits allow your obstetrician to spot potential complications early.
  • Manage Existing Conditions: If you have a chronic medical condition, work with your obstetrician to manage it before and during pregnancy.
  • Limit Pregnancy Risks: Avoid activities that could harm you or your baby, like exposure to harmful chemicals, heavy lifting, and certain physical activities.
