Summary
Surrogacy has helped thousands of individuals and couples fulfill their dream of becoming parents. Whether intended parents are facing infertility, medical conditions, or other circumstances that make pregnancy difficult or unsafe, surrogacy offers a life-changing opportunity to build a family. While modern medical advances have made gestational surrogacy safer than ever, it is important to remember that every pregnancy carries certain health risks including surrogate pregnancies.
Most surrogates experience healthy pregnancies and deliver healthy babies, particularly because they undergo extensive medical, psychological, and legal screening before beginning the journey. However, complications such as gestational diabetes, pre-eclampsia, placenta previa, preterm labor, and emotional stress can still occur. Understanding these risks allows surrogates, intended parents, and healthcare providers to work together to ensure the safest possible pregnancy.
The good news is that many pregnancy complications can be identified early through regular prenatal care, healthy lifestyle habits, and close medical supervision. Early intervention often leads to better outcomes for both the surrogate and the baby.
In this article, we’ll explore the most common pregnancy risks associated with surrogacy, explain why they occur, and discuss practical ways to reduce those risks. Whether you’re considering becoming a surrogate, planning a surrogacy journey, or simply seeking reliable information, understanding these potential complications can help you make informed decisions with confidence.
Introduction
Choosing to become a surrogate is one of the most generous gifts one person can offer another.
For intended parents, surrogacy represents hope after years of infertility, pregnancy loss, or medical challenges. For the surrogate, it is an opportunity to help create a family while experiencing the unique journey of pregnancy.
Although surrogacy is often viewed as a carefully planned medical process, it’s important to remember that it is still a pregnancy and every pregnancy carries certain risks.
Fortunately, surrogates are usually among the healthiest pregnant individuals because agencies and fertility specialists carefully evaluate their physical and emotional health before approval. Even so, conditions such as gestational diabetes, pregnancy-induced hypertension, placental complications, or premature labor can occasionally develop despite excellent prenatal care.
Understanding these possibilities does not mean expecting complications.
Instead, knowledge helps everyone involved recognize warning signs early, seek timely medical care, and make informed choices throughout the pregnancy.
With appropriate screening, experienced healthcare providers, emotional support, and regular prenatal monitoring, most surrogacy journeys result in positive outcomes for both the surrogate and the baby.
Understanding Surrogacy
Surrogacy is an arrangement in which a woman carries and delivers a baby for another individual or couple, known as the intended parents.
This option is often chosen by:
- Couples experiencing infertility.
- Women with medical conditions that make pregnancy unsafe.
- Individuals born without a uterus or with uterine abnormalities.
- Same-sex male couples.
- Single individuals wishing to become parents.
Today, most surrogacy arrangements involve gestational surrogacy, which has become the standard practice in many countries.
Traditional Surrogacy
- In traditional surrogacy, the surrogate’s own egg is fertilized using sperm from the intended father or a donor.
- Because her egg is used, the surrogate is genetically related to the child.
- Traditional surrogacy is now relatively uncommon due to its legal and emotional complexities.
Gestational Surrogacy
- Gestational surrogacy involves creating an embryo through in vitro fertilization (IVF) using the intended parents’ eggs and sperm or donor eggs and sperm if needed.
- The embryo is then transferred into the surrogate’s uterus.
- In this arrangement, the surrogate has no genetic relationship to the baby.
- Most modern surrogacy programs use gestational surrogacy because it provides greater medical, legal, and emotional clarity for everyone involved.
Is Surrogacy Safe?
One of the most common questions prospective surrogates ask is whether surrogacy is safe. The answer is reassuring. For carefully screened, healthy women, gestational surrogacy is generally considered as safe as any other low-risk pregnancy.
Before becoming pregnant, surrogates typically undergo:
- Comprehensive medical evaluations.
- Fertility assessments.
- Blood testing.
- Uterine examinations.
- Psychological evaluations.
- Lifestyle assessments.
- Review of previous pregnancy history.
Only women with a history of healthy pregnancies and deliveries are usually approved. However, even healthy pregnancies can occasionally develop complications. This is why ongoing prenatal care remains essential throughout the surrogacy journey.
Why Pregnancy Risks Can Still Occur
- Pregnancy naturally creates major changes throughout the body.
- The heart pumps more blood.
- Hormone levels rise dramatically.
- Blood sugar regulation changes.
- Blood pressure fluctuates.
- The immune system adapts.
These normal physiological changes help support the developing baby but may also increase the likelihood of certain pregnancy-related complications.
For surrogates, additional factors may sometimes contribute, including:
- IVF-related hormonal treatments.
- Carrying twins or multiples.
- Maternal age.
- Pre-existing medical conditions.
- Previous pregnancy history.
Fortunately, regular prenatal monitoring allows healthcare providers to identify many complications before they become serious.
10 Pregnancy Risks in Surrogacy
1. Hyperemesis Gravidarum (Severe Pregnancy Nausea)
Morning sickness is common during early pregnancy.
However, some women experience a much more severe condition called hyperemesis gravidarum (HG).
Unlike typical nausea, HG causes persistent vomiting that can lead to dehydration, weight loss, nutritional deficiencies, and hospitalization if left untreated.
Although relatively uncommon, hyperemesis gravidarum may occur during surrogate pregnancies just as it does in other pregnancies.
Possible Risk Factors
Several factors increase the likelihood of developing HG:
- Elevated pregnancy hormone (hCG) levels.
- Previous history of HG.
- Carrying twins or higher-order multiples.
- Family history of severe pregnancy nausea.
Potential Complications
Without treatment, HG may result in:
- Severe dehydration.
- Electrolyte imbalances.
- Weight loss.
- Fatigue.
- Nutritional deficiencies.
- Reduced quality of life during pregnancy.
Management
Fortunately, effective treatments are available.
Depending on symptom severity, healthcare providers may recommend:
- Anti-nausea medications.
- Intravenous fluids.
- Nutritional support.
- Frequent monitoring.
Early treatment usually improves both maternal comfort and pregnancy outcomes.
2. Gestational Diabetes Mellitus (GDM)
Gestational diabetes develops when pregnancy hormones make it difficult for the body to regulate blood sugar levels.
Most women have no symptoms, which is why routine screening is recommended between 24 and 28 weeks of pregnancy.
Approximately 2–10% of pregnancies are affected by gestational diabetes.
Risk Factors
Women may be at greater risk if they:
- Are over age 35.
- Have obesity.
- Have previously experienced gestational diabetes.
- Have a family history of diabetes.
- Carry multiple babies.
Potential Complications
If blood sugar remains uncontrolled, possible complications include:
- Larger-than-average babies (macrosomia).
- Birth injuries.
- Increased likelihood of cesarean delivery.
- Preterm birth.
- Low blood sugar in newborns after delivery.
Management
The majority of gestational diabetes cases can be managed through:
- Balanced nutrition.
- Regular physical activity.
- Blood sugar monitoring.
- Medication or insulin if necessary.
With proper treatment, most pregnancies continue safely.
3. Pre-eclampsia
Pre-eclampsia is one of the most closely monitored pregnancy complications because it affects both maternal and fetal health.
It typically develops after 20 weeks of pregnancy and is characterized by:
- High blood pressure.
- Protein in the urine.
- Possible liver, kidney, or other organ involvement.
If untreated, severe pre-eclampsia can progress to eclampsia, a life-threatening condition involving seizures.
Risk Factors
Several factors may increase risk, including:
- First pregnancy.
- IVF pregnancies.
- Multiple gestation.
- Chronic hypertension.
- Diabetes.
- Kidney disease.
- Obesity.
Possible Complications
Pre-eclampsia may lead to:
- Placental insufficiency.
- Restricted fetal growth.
- Preterm delivery.
- Stroke.
- Organ damage.
Management
Early diagnosis is essential.
Prenatal visits allow healthcare providers to monitor:
- Blood pressure.
- Urine protein.
- Blood tests.
- Fetal growth.
For women at higher risk, low-dose aspirin may be recommended under medical supervision.
4. Placenta Previa
Placenta previa occurs when the placenta partially or completely covers the cervix. Because the placenta blocks the baby’s exit, vaginal delivery may become unsafe. This condition usually becomes apparent during routine ultrasound examinations.
Risk Factors
Risk increases among women with:
- Previous cesarean deliveries.
- Prior uterine surgery.
- Multiple pregnancies.
- Maternal age over 35 years.
- Previous placenta previa.
Possible Complications
Placenta previa may cause:
- Painless vaginal bleeding.
- Hospitalization.
- Preterm birth.
- Need for cesarean delivery.
Management
Treatment depends on severity.
Healthcare providers may recommend:
- Reduced physical activity.
- Pelvic rest.
- Frequent ultrasounds.
- Hospital monitoring if bleeding occurs.
Many women with placenta previa deliver healthy babies through carefully planned cesarean births.
5. Premature Labor
A full-term pregnancy lasts approximately 40 weeks. Labor beginning before 37 weeks is considered preterm. Although many premature babies do very well, early birth increases the likelihood of neonatal complications.
Risk Factors
Preterm labor becomes more likely when:
- Carrying twins or triplets.
- Previous premature birth.
- Uterine abnormalities.
- Pregnancy-related infections.
- Certain medical conditions are present.
Possible Complications
Premature babies may experience:
- Breathing difficulties.
- Feeding problems.
- Lower birth weight.
- Temperature regulation issues.
- Longer hospital stays.
Management
Healthcare providers monitor women closely for signs such as:
- Regular contractions.
- Pelvic pressure.
- Fluid leakage.
- Cervical changes.
When identified early, medications may sometimes delay labor long enough to improve neonatal outcomes.
6. Cardiovascular Changes and Pregnancy-Related Heart Complications
Pregnancy naturally places additional demands on the heart and circulatory system. During pregnancy, blood volume increases by nearly 40–50%, and the heart works harder to pump blood to both the mother and the developing baby.
For most healthy surrogates, these changes are well tolerated. However, in some cases, pregnancy can reveal or worsen underlying cardiovascular conditions.
Potential Risks
Although uncommon, pregnancy-related cardiovascular complications may include:
- Pregnancy-induced hypertension
- Arrhythmias (irregular heartbeat)
- Peripartum cardiomyopathy (a rare weakening of the heart muscle)
- Blood clot formation
Women with previously undiagnosed heart conditions may experience symptoms for the first time during pregnancy.
Warning Signs
Contact your healthcare provider immediately if you experience:
- Chest pain
- Persistent shortness of breath
- Fainting episodes
- Rapid or irregular heartbeat
- Severe swelling in the legs
- Extreme fatigue beyond normal pregnancy tiredness
How It’s Managed
Routine prenatal visits include blood pressure monitoring and cardiovascular assessments. If any concerns arise, an obstetrician may work alongside a cardiologist to ensure both maternal and fetal safety.
Fortunately, serious heart complications remain rare among carefully screened surrogate mothers.
7. Urinary Tract Infections (UTIs)
Urinary tract infections are among the most common infections during pregnancy.
Pregnancy hormones relax the muscles of the urinary tract, slowing urine flow and making bacterial growth more likely. As the uterus enlarges, pressure on the bladder further increases the risk.
Common Symptoms
A UTI may cause:
- Burning during urination
- Frequent urge to urinate
- Pelvic discomfort
- Cloudy or foul-smelling urine
- Fever (in more serious infections)
Sometimes, pregnant women have no noticeable symptoms, which is why routine urine tests are part of prenatal care.
Why Early Treatment Matters
Untreated UTIs can progress to kidney infections, which may increase the risk of:
- Preterm labor
- Low birth weight
- Maternal illness
Prevention Tips
Surrogates can reduce their risk by:
- Drinking plenty of water.
- Emptying the bladder regularly.
- Practicing good personal hygiene.
- Attending all prenatal appointments for routine screening.
Most UTIs respond well to pregnancy-safe antibiotics when detected early.
8. Ovarian Hyperstimulation Syndrome (OHSS)
Although OHSS occurs before pregnancy rather than during it, it remains an important consideration in gestational surrogacy because it is associated with fertility treatment.
Before embryo transfer, intended mothers or egg donors typically receive fertility medications to stimulate egg production. In rare situations involving egg retrieval, ovarian hyperstimulation syndrome may develop.
A surrogate herself usually does not undergo ovarian stimulation in gestational surrogacy unless she is also serving as an egg donor (which is uncommon in modern surrogacy).
Symptoms of OHSS
Symptoms range from mild to severe and may include:
- Abdominal bloating
- Pelvic pain
- Nausea
- Rapid weight gain
- Fluid accumulation
- Shortness of breath (in severe cases)
Management
Most mild cases improve with rest, hydration, and close monitoring.
Severe cases require hospital care to manage fluid balance and prevent complications.
Advances in fertility medicine have greatly reduced the frequency of severe OHSS through individualized medication protocols.
9. Emotional and Psychological Challenges
While discussions about surrogacy often focus on physical health, emotional wellbeing is equally important.
Surrogates experience hormonal changes, physical discomfort, and the emotional demands of pregnancy just like any expectant mother.
In addition, they may also navigate:
- The emotional responsibility of carrying a child for another family.
- Public misunderstanding about surrogacy.
- Temporary lifestyle changes.
- Balancing pregnancy with work and family responsibilities.
- Emotional adjustment after delivery.
Most surrogates describe the experience as deeply meaningful, but emotional ups and downs are entirely normal.
Psychological Perspective
Research shows that surrogates who receive:
- Strong family support
- Professional counseling
- Positive relationships with intended parents
- Clear expectations before pregnancy
generally report high levels of emotional wellbeing and satisfaction with their surrogacy experience.
Supporting Emotional Health
Healthy emotional care includes:
- Open communication.
- Counseling when needed.
- Joining surrogate support groups.
- Practicing stress-management techniques.
- Maintaining healthy relationships.
Mental wellbeing deserves the same attention as physical health throughout pregnancy.
10. Cesarean Delivery and Delivery-Related Complications
Not every surrogate pregnancy ends with a vaginal birth.
Some pregnancies require cesarean delivery due to medical reasons such as:
- Placenta previa.
- Breech presentation.
- Multiple pregnancy.
- Fetal distress.
- Previous cesarean births.
- Failure to progress during labor.
A cesarean section is a common and generally safe surgical procedure, but like any surgery, it carries certain risks.
Possible Risks
These may include:
- Infection.
- Bleeding.
- Blood clots.
- Longer recovery time.
- Temporary limitations in physical activity.
Recovery
With appropriate postoperative care, pain management, and follow-up appointments, most surrogates recover well and return to their normal activities within several weeks.
The delivery plan is always individualized based on the health of both the surrogate and the baby.
Factors That May Increase Pregnancy Risks in Surrogacy
Although surrogates undergo rigorous screening, certain factors can still influence pregnancy outcomes.
These include:
- Maternal age over 35 years.
- Obesity.
- High blood pressure.
- Diabetes.
- Previous pregnancy complications.
- Carrying twins or higher-order multiples.
- Smoking or substance use.
- Certain chronic medical conditions.
Fortunately, most agencies only approve women with a history of healthy pregnancies, significantly reducing overall risk.
How Surrogates Can Reduce Pregnancy Risks
While no pregnancy is entirely risk-free, healthy habits and regular medical care can greatly reduce complications.
Attend Every Prenatal Appointment
Regular check-ups allow healthcare providers to detect potential problems before symptoms appear.
Follow Medical Advice Carefully
Take prescribed medications, prenatal vitamins, and follow recommendations regarding nutrition, activity, and monitoring.
Maintain a Healthy Lifestyle
Support your pregnancy by:
- Eating a balanced diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats.
- Drinking adequate water.
- Getting enough sleep.
- Remaining physically active if approved by your healthcare provider.
Know the Warning Signs
Seek immediate medical attention if you experience:
- Heavy bleeding.
- Severe abdominal pain.
- Persistent headaches.
- Vision changes.
- Decreased fetal movement.
- Fluid leakage.
- Chest pain or difficulty breathing.
Early treatment often prevents more serious complications.
Prioritize Emotional Wellbeing
Mental health is an important part of prenatal care.
Stay connected with supportive family members, intended parents, counselors, or surrogate communities throughout your journey.

Frequently Asked Questions
Is surrogacy more dangerous than a regular pregnancy?
For healthy, carefully screened women, gestational surrogacy carries risks similar to those of other pregnancies. The use of IVF and factors such as multiple pregnancies may slightly increase certain risks, but close medical monitoring helps manage these effectively.
Can surrogate mothers develop pregnancy complications?
Yes. Like any pregnant woman, surrogates can experience conditions such as gestational diabetes, pre-eclampsia, or preterm labor. However, most surrogates have healthy pregnancies because they receive thorough medical screening and regular prenatal care.
Who pays for medical care if complications occur?
This depends on the legal agreement and the laws of the country or region where the surrogacy takes place. In many arrangements, intended parents are responsible for pregnancy-related medical expenses, often through insurance or contractual agreements.
Can surrogates have future pregnancies after surrogacy?
In most cases, yes. Women who experience healthy surrogate pregnancies often go on to have additional pregnancies, provided there are no medical complications that would make future pregnancies unsafe. Individual circumstances should always be discussed with a healthcare provider.
How can intended parents support their surrogate?
Maintaining open communication, showing appreciation, respecting medical guidance, and providing emotional support throughout the pregnancy can help foster a positive experience for everyone involved.
Conclusion
Surrogacy is a remarkable journey built on compassion, trust, and collaboration. For many intended parents, it represents the possibility of creating a family when other paths to parenthood have been difficult or impossible. For surrogates, it is an extraordinary act of generosity that can profoundly change another family’s life.
Although surrogate pregnancies carry many of the same medical risks as any pregnancy, modern fertility medicine, comprehensive screening, and high-quality prenatal care have made gestational surrogacy safer than ever before. Most surrogates experience healthy pregnancies and successful deliveries, particularly when they follow medical advice and attend regular prenatal appointments.
Understanding potential complications is not meant to create fear it is meant to promote preparedness. Recognizing warning signs early, maintaining healthy lifestyle habits, and prioritizing both physical and emotional wellbeing help ensure the best possible outcomes for the surrogate, the baby, and the intended parents.
Ultimately, knowledge empowers everyone involved in the surrogacy journey. With informed decision-making, compassionate healthcare, and strong support systems, surrogacy can be a safe, rewarding, and life-changing experience.
