Pregnancy Complications
What is Pregnancy Complications?
Pregnancy complications are health problems that happen during pregnancy. They can affect the mother, the baby, or both. Some complications develop early in pregnancy, while others appear later in the second or third trimester.
Common pregnancy complications include preeclampsia, gestational diabetes, placental problems, and blood clotting disorders. Many of these conditions can be detected through blood tests that measure specific biomarkers. Early detection helps doctors provide the right care at the right time.
Not all pregnancies have complications. However, certain risk factors increase the chance of problems. Regular prenatal care and blood testing help identify issues before they become serious. This proactive approach protects both mother and baby throughout pregnancy.
Symptoms
- High blood pressure that develops during pregnancy
- Protein in the urine, which may signal preeclampsia
- Severe headaches that do not respond to usual treatments
- Vision changes including blurred vision or seeing spots
- Sudden swelling in the face, hands, or feet
- Upper abdominal pain, usually under the ribs on the right side
- Decreased fetal movement or changes in baby's activity
- Vaginal bleeding or fluid leakage
- Severe nausea and vomiting beyond the first trimester
- Signs of blood clotting problems like unusual bruising
Some pregnancy complications have no obvious symptoms at first. This is why regular prenatal checkups and blood tests are essential for every pregnancy.

Causes and risk factors
Pregnancy complications can result from many different factors. Pre-existing health conditions like high blood pressure, diabetes, or autoimmune disorders increase the risk. Blood clotting disorders can lead to problems with the placenta and blood flow to the baby. Genetic factors, including MTHFR mutations, can affect how your body processes important nutrients like folate. Low folate levels during pregnancy raise the risk of neural tube defects in developing babies.
Age also plays a role in pregnancy complications. Women over 35 or under 17 face higher risks. Carrying multiple babies, having a history of pregnancy complications, or certain lifestyle factors like smoking can also contribute. Some complications happen even without clear risk factors. Regular monitoring through blood tests helps identify warning signs early so doctors can step in when needed.
How it's diagnosed
Doctors diagnose pregnancy complications through a combination of physical exams, medical history, and blood tests. Blood work can reveal important biomarkers that signal potential problems. Tests for fibrinogen levels help assess clotting function, which naturally increases during pregnancy but may indicate preeclampsia when too high. Free protein S antigen testing checks for blood clotting disorders that can affect placental health. RBC folate testing ensures adequate levels to prevent neural tube defects in the developing baby.
Additional tests measure placental isoenzymes, which can indicate complications like preeclampsia, eclampsia, or placental insufficiency. MTHFR mutation testing identifies genetic factors that affect nutrient processing. Rite Aid offers these specialized add-on tests to help monitor pregnancy health. Early detection allows for timely interventions that protect both mother and baby throughout the pregnancy journey.
Treatment options
- Increased prenatal monitoring with more frequent checkups and testing
- Blood pressure medications for preeclampsia or gestational hypertension
- Folate supplementation, especially for women with MTHFR mutations or low RBC folate
- Blood thinning medications for clotting disorders when appropriate
- Bed rest or reduced activity levels for certain complications
- Dietary changes including reduced sodium for high blood pressure
- Early delivery when the mother or baby's health is at risk
- Hospitalization for severe complications requiring close observation
- Corticosteroids to help develop baby's lungs if early delivery is likely
- Regular ultrasounds to monitor baby's growth and placental function

Frequently asked questions
The most common pregnancy complications include preeclampsia, gestational diabetes, placental problems, and blood clotting disorders. Preeclampsia affects about 5 to 8 percent of pregnancies and involves high blood pressure and organ damage. Many complications can be managed effectively with early detection and proper medical care.
Some blood tests can detect risk factors before symptoms appear. RBC folate testing is important early in pregnancy to prevent neural tube defects. MTHFR mutation testing can identify genetic risks before conception or early in pregnancy. Other biomarkers like fibrinogen and placental isoenzymes become more relevant later in pregnancy when certain complications typically develop.
Preeclampsia is a serious pregnancy complication involving high blood pressure and signs of organ damage, usually affecting the liver or kidneys. It typically develops after 20 weeks of pregnancy. Doctors diagnose it through blood pressure readings, urine protein tests, and blood work including fibrinogen levels and placental isoenzyme measurements.
Folate is essential for your baby's neural tube development, which forms the brain and spinal cord. Low RBC folate levels significantly increase the risk of neural tube defects like spina bifida. Testing helps ensure you have adequate levels, especially if you have MTHFR mutations that affect how your body processes folate.
The MTHFR mutation test checks for genetic variations that affect how your body converts folate into its active form. People with these mutations may need higher doses of folate or a special form called methylfolate. This testing helps prevent complications related to poor folate metabolism during pregnancy.
Blood clotting disorders can increase the risk of blood clots forming in the placenta. This reduces blood flow and nutrients to the baby, potentially causing placental insufficiency or pregnancy loss. Tests like protein S antigen and fibrinogen help identify these disorders so doctors can provide appropriate treatment.
While not all pregnancy complications can be prevented, many can be managed with early detection. Taking prenatal vitamins with adequate folate, maintaining a healthy weight, managing pre-existing conditions, and avoiding smoking all reduce risks. Regular blood testing and prenatal care help catch problems early when treatment is most effective.
Placental isoenzymes are proteins produced by the placenta during pregnancy. Elevated levels can indicate serious complications like preeclampsia, eclampsia, or placental insufficiency. Testing these biomarkers helps doctors assess placental health and identify problems that could affect the baby's growth and development.
Most pregnant women have blood tests at the first prenatal visit and then periodically throughout pregnancy. Women with risk factors or existing complications may need more frequent testing. Your healthcare provider will recommend a testing schedule based on your individual risk factors and pregnancy progression.
Abnormal results do not always mean serious problems, but they do require follow-up. Your doctor may order additional tests, increase monitoring frequency, or recommend specific treatments. Early intervention based on blood test results often prevents complications from becoming severe and improves outcomes for both mother and baby.
