Pregnancy Complications
What is Pregnancy complications?
Pregnancy complications are health problems that develop during pregnancy. They can affect the mother, the baby, or both. Some complications arise from existing health conditions, while others develop unexpectedly during pregnancy. Common complications include preeclampsia, gestational diabetes, blood clots, and placental problems.
Certain blood markers change during pregnancy to support the growing baby. However, some changes can signal potential problems. For example, fibrinogen is a protein that helps blood clot. It naturally rises during pregnancy, but very high levels may increase the risk of dangerous clots or preeclampsia. D-Dimer is a substance created when blood clots break down. Elevated D-Dimer can indicate clotting complications or placental issues like placental abruption.
Early detection of pregnancy complications helps protect both mother and baby. Regular monitoring through blood tests allows doctors to spot warning signs before they become serious. Many complications can be managed successfully with proper medical care and lifestyle changes.
Symptoms
- High blood pressure or sudden blood pressure spikes
- Protein in urine
- Severe headaches that do not improve with rest
- Vision changes including blurriness or seeing spots
- Sudden swelling in face, hands, or feet
- Upper abdominal pain, especially under the ribs
- Shortness of breath or chest pain
- Leg pain, warmth, or swelling on one side
- Vaginal bleeding or fluid leakage
- Decreased fetal movement
Many pregnancy complications develop without obvious symptoms at first. This is why regular prenatal visits and blood tests are essential. Some women feel perfectly fine while dangerous conditions like preeclampsia or blood clots are developing silently.

Causes and risk factors
Pregnancy complications can stem from multiple factors. Pre-existing conditions like high blood pressure, diabetes, autoimmune disorders, or clotting disorders increase risk. Age plays a role too. Women under 20 or over 35 face higher complication rates. First pregnancies and pregnancies with multiples carry additional risk. Obesity, smoking, and excessive alcohol use during pregnancy also raise the likelihood of complications.
Some complications arise from how the body adapts to pregnancy. Blood naturally becomes thicker during pregnancy to prevent excessive bleeding during delivery. However, this also increases clotting risk. The placenta can develop abnormally, leading to conditions like placental abruption or placenta previa. Hormonal changes can trigger gestational diabetes or thyroid problems. Genetic factors and family history of pregnancy complications also contribute to individual risk.
How it's diagnosed
Pregnancy complications are diagnosed through a combination of physical exams, blood tests, and imaging. Your doctor will monitor blood pressure at every prenatal visit. Urine tests check for protein, which can signal preeclampsia. Blood tests measure clotting factors like fibrinogen and D-Dimer to assess thrombosis risk. Glucose tests screen for gestational diabetes. Ultrasounds evaluate fetal growth and placental position.
Rite Aid offers add-on blood testing that measures fibrinogen activity and D-Dimer levels. These tests help monitor clotting risk and detect early signs of complications like preeclampsia or thrombosis. Testing is available at over 2,000 Quest Diagnostics locations nationwide. Early detection through regular blood work allows your healthcare team to intervene quickly if problems arise.
Treatment options
- Blood pressure medications safe for pregnancy when needed
- Blood thinners like low-dose aspirin or heparin for clotting disorders
- Insulin or dietary changes for gestational diabetes
- Bed rest or reduced activity in certain situations
- Increased prenatal monitoring with more frequent visits
- Eating a balanced diet rich in vegetables, lean protein, and whole grains
- Staying hydrated with at least 8 glasses of water daily
- Gentle exercise like walking or prenatal yoga when approved by your doctor
- Early delivery if complications threaten mother or baby health
- Hospitalization for severe cases requiring close monitoring

Frequently asked questions
The most common complications include preeclampsia, gestational diabetes, blood clots, placental abruption, and preterm labor. Preeclampsia affects about 5 to 8 percent of pregnancies and involves high blood pressure and organ stress. Gestational diabetes develops in roughly 6 to 9 percent of pregnant women. Blood clots are more likely during pregnancy due to natural changes in clotting factors.
Blood tests measure specific markers that change when complications develop. Fibrinogen levels naturally rise during pregnancy, but very high levels may signal increased clotting risk or preeclampsia. D-Dimer measures clot breakdown products, and elevated levels can indicate dangerous clotting or placental problems. Regular blood monitoring helps catch these changes early before symptoms appear.
Testing schedules depend on your individual risk factors. Most women get blood work at the first prenatal visit and again during each trimester. Women with high blood pressure, previous pregnancy complications, or clotting disorders need more frequent testing. Your doctor may order additional tests if you develop symptoms like severe headaches, swelling, or leg pain.
While not all complications can be prevented, many can be managed or reduced through proactive care. Maintaining a healthy weight before pregnancy lowers risk significantly. Taking prenatal vitamins with folic acid supports healthy development. Regular prenatal visits allow early detection and intervention. Managing pre-existing conditions like diabetes or high blood pressure before conception also helps prevent complications.
Preeclampsia is a serious condition involving high blood pressure and signs of organ damage during pregnancy. It typically develops after 20 weeks and can harm the liver, kidneys, and brain. Doctors detect it through blood pressure readings, urine protein tests, and blood work including liver enzymes and clotting factors. High fibrinogen levels may indicate increased preeclampsia risk.
Pregnant women are 5 to 10 times more likely to develop blood clots than non-pregnant women. Pregnancy naturally increases clotting factors to prevent bleeding during delivery, but this also raises clot risk. Deep vein thrombosis in the legs is most common and can lead to serious complications if untreated. Blood tests measuring fibrinogen and D-Dimer help assess this risk.
Eating a balanced diet with limited processed foods and added sugars helps control blood sugar and blood pressure. Staying active with gentle exercise like walking or swimming improves circulation and reduces clot risk. Getting adequate sleep, managing stress, and staying hydrated all support healthy pregnancy. Avoiding smoking and alcohol is essential for preventing complications.
Yes, many women have healthy pregnancies after experiencing complications in previous pregnancies. Close monitoring and early intervention make a significant difference. Your doctor may recommend earlier and more frequent testing, preventive medications like low-dose aspirin, or lifestyle modifications. Discussing your history at your first prenatal visit helps your care team create a personalized monitoring plan.
D-Dimer naturally rises during pregnancy because the body produces more clotting factors. However, very high levels can signal active clotting problems like deep vein thrombosis or pulmonary embolism. Elevated D-Dimer can also indicate placental complications like abruption, where the placenta separates from the uterus. Your doctor will interpret results based on your symptoms and other test findings.
Complications become dangerous when left undetected or untreated. Severe preeclampsia can progress to eclampsia, causing seizures and organ failure. Blood clots can travel to the lungs, causing pulmonary embolism. Placental abruption can lead to severe bleeding and oxygen deprivation for the baby. Immediate medical attention is needed for severe headaches, chest pain, heavy bleeding, or sudden vision changes.
