Causes & Risk Factors

Several factors can contribute to Preterm Labor and Delivery.

The exact cause of preterm labor often remains a mystery, even to experienced doctors.

The exact cause of preterm labor often remains a mystery, even to experienced doctors. Your body has an intricate system of hormones and physical changes that normally keep your cervix closed and your uterus calm until it's time for delivery. When something disrupts this delicate balance, labor can begin too early. Sometimes infections trigger the process, particularly those affecting the amniotic fluid, placenta, or reproductive tract.

Certain pregnancy complications can also set preterm labor in motion.

Certain pregnancy complications can also set preterm labor in motion. Problems with the placenta, such as placental abruption where it separates from the uterine wall, can trigger early labor. Carrying multiple babies naturally increases the risk because your uterus stretches more than usual. Issues with the cervix, like incompetent cervix where it begins opening too early, can lead to preterm delivery as well.

Stress plays a role too, though researchers are still working to understand exactly how.

Stress plays a role too, though researchers are still working to understand exactly how. Chronic stress, whether from life circumstances, physical demands, or medical conditions, appears to increase preterm birth risk. Your body's response to ongoing stress can affect hormone levels and inflammation, potentially triggering labor before your baby is ready to arrive.

Risk Factors

Previous preterm birth or pregnancy loss after 14 weeks
Carrying twins, triplets, or other multiples
Certain infections including urinary tract or sexually transmitted infections
Chronic conditions like diabetes, high blood pressure, or autoimmune disorders
Being younger than 18 or older than 35 during pregnancy
African American ethnicity
Smoking, drinking alcohol, or using illicit drugs
High levels of physical or emotional stress
Problems with the uterus or cervix
Short time between pregnancies (less than 18 months)
Low pre-pregnancy weight or being significantly underweight
Lack of prenatal care or late start to prenatal visits

Diagnosis

How healthcare professionals diagnose Preterm Labor and Delivery:

1
When you arrive at the hospital with possible preterm labor symptoms, your medical team springs into action with a systematic approach.
When you arrive at the hospital with possible preterm labor symptoms, your medical team springs into action with a systematic approach. First, they'll monitor your contractions using a device placed on your belly that tracks both contraction strength and your baby's heart rate. This external monitoring helps doctors see if you're having true labor contractions and how your baby is responding to them.
2
The cervical exam comes next and provides crucial information.
The cervical exam comes next and provides crucial information. Your doctor will check if your cervix has started to thin out (efface) or open (dilate). In normal pregnancy, your cervix stays thick and closed until close to your due date. If it's shortening or opening before 37 weeks, especially combined with regular contractions, preterm labor becomes the likely diagnosis. Sometimes doctors use ultrasound to measure cervical length more precisely.
3
Several other tests help complete the picture.
Several other tests help complete the picture. A fetal fibronectin test checks for a protein that acts like glue between the amniotic sac and uterine lining. When this protein appears in vaginal secretions after 22 weeks but before 35 weeks, it can signal increased preterm birth risk. Your doctor might also test for infections, check your baby's position and estimated weight via ultrasound, and run blood tests to assess your overall health status.

Complications

Babies born prematurely face challenges that depend largely on how early they arrive.
Those born between 34 and 36 weeks (late preterm) usually do well with minimal intervention, though they may need help with feeding, temperature regulation, or mild breathing difficulties.
Babies born earlier face more serious complications.
Respiratory distress syndrome tops the list, occurring when underdeveloped lungs lack sufficient surfactant, the substance that keeps air sacs open.
Other potential complications include brain bleeds, feeding difficulties, temperature control problems, and increased infection risk due to immature immune systems.
Very premature babies might develop chronic lung disease, vision problems, or developmental delays.
However, medical advances continue to improve outcomes.
Many babies who once faced poor prognoses now grow up to lead completely normal lives.
Early intervention services, specialized follow-up care, and family support all contribute to better long-term outcomes for preterm babies and their families.

Prevention

Quit smoking and avoid secondhand smoke completely
Eliminate alcohol and recreational drug use
Maintain a healthy weight before and during pregnancy
Manage chronic conditions like diabetes and high blood pressure
Take prenatal vitamins with folic acid daily
Get recommended vaccines including flu shots
Practice good hygiene to prevent infections
Space pregnancies at least 18 months apart when possible

Treatment Approaches

The treatment approach for preterm labor depends largely on how far along you are and how your baby is doing.

The treatment approach for preterm labor depends largely on how far along you are and how your baby is doing. If you're between 24 and 34 weeks pregnant, doctors often try to slow or stop labor using medications called tocolytics. These drugs, including terbutaline and nifedipine, work by relaxing the uterine muscles and can sometimes buy precious time for your baby's continued development. However, they're typically used as a short-term measure rather than a long-term solution.

Medication

Corticosteroids represent one of the most important advances in preterm labor treatment.

Corticosteroids represent one of the most important advances in preterm labor treatment. When given to mothers between 24 and 34 weeks of pregnancy, these medications cross the placenta and help accelerate the baby's lung development. Betamethasone or dexamethasone injections given over 24 to 48 hours can significantly reduce the risk of serious breathing problems if the baby is born prematurely. The benefits are most pronounced when delivery occurs within seven days of treatment.

MedicationAnti-inflammatory

If you're at high risk for delivering within the next week and you're less than 32 weeks pregnant, you might receive magnesium sulfate.

If you're at high risk for delivering within the next week and you're less than 32 weeks pregnant, you might receive magnesium sulfate. This medication doesn't stop labor, but research shows it can help protect your baby's developing brain and reduce the risk of cerebral palsy. The treatment involves continuous IV infusion and requires careful monitoring since it can cause side effects like nausea, weakness, and changes in reflexes.

Medication

Sometimes the safest option is to allow preterm delivery to proceed, especially if you've developed serious complications like severe preeclampsia or placental abruption.

Sometimes the safest option is to allow preterm delivery to proceed, especially if you've developed serious complications like severe preeclampsia or placental abruption. In these cases, continuing the pregnancy might pose greater risks than preterm birth. Your medical team will prepare for delivery in a hospital with a neonatal intensive care unit (NICU) equipped to care for premature babies. Recent advances in NICU care have dramatically improved survival rates and long-term outcomes for babies born as early as 24 weeks.

Living With Preterm Labor and Delivery

Having a baby born prematurely brings a unique set of emotions and practical challenges. The NICU experience can feel overwhelming at first, with monitors beeping, tiny tubes and wires, and medical staff constantly checking on your baby. Remember that this intensive care gives your baby the best possible start. Ask questions, participate in your baby's care as much as possible, and take advantage of support services the hospital offers.

Building your support network becomes crucial during this time.Building your support network becomes crucial during this time. Connect with other NICU parents who understand what you're going through. Many hospitals have support groups or can connect you with organizations like March of Dimes that offer resources for families of preterm babies. Don't hesitate to ask family and friends for specific help, whether it's bringing meals, helping with household tasks, or simply listening when you need to talk.

Planning for the future helps too.Planning for the future helps too. Your baby will likely need more frequent medical appointments and may benefit from early intervention services like physical therapy, occupational therapy, or speech therapy. Keep detailed records of your baby's medical care, as this information will be valuable for future healthcare providers. Many preterm babies catch up to their full-term peers by age two, but some may need ongoing support. The key is staying connected with your healthcare team and celebrating each milestone along the way.

Frequently Asked Questions

Can bed rest prevent preterm labor?

Current research shows that bed rest doesn't prevent preterm birth and may actually cause harm by increasing blood clot risk and muscle weakness. Most doctors no longer prescribe bed rest for preterm labor prevention.

Will my baby definitely have problems if born prematurely?

Not necessarily. Many preterm babies, especially those born after 32 weeks, do very well with minimal or no long-term complications. Outcomes depend on gestational age at birth and access to quality medical care.

Can I prevent preterm labor if I've had it before?

Having one preterm birth does increase your risk, but many women go on to have full-term pregnancies. Your doctor might recommend progesterone injections or more frequent monitoring to help prevent recurrence.

How long will my preterm baby need to stay in the hospital?

Hospital stays vary widely depending on gestational age at birth and individual circumstances. Many babies stay until their original due date, but some go home earlier or later depending on their progress.

Should I avoid exercise during pregnancy to prevent preterm labor?

For most women, regular moderate exercise during pregnancy is safe and beneficial. However, women at high risk for preterm birth should discuss activity levels with their healthcare provider for personalized recommendations.

Can stress really cause preterm labor?

Chronic, severe stress does appear to increase preterm birth risk, though the exact mechanisms aren't fully understood. Managing stress through healthy coping strategies is beneficial for overall pregnancy health.

What's the difference between preterm labor and Braxton Hicks contractions?

Preterm labor contractions are regular, get stronger over time, and cause cervical changes. Braxton Hicks contractions are irregular, don't increase in intensity, and don't affect the cervix.

Will my insurance cover NICU care for my preterm baby?

Most insurance plans cover medically necessary NICU care, but costs can vary significantly. Contact your insurance provider early to understand your coverage and any prior authorization requirements.

Can I breastfeed my preterm baby?

Yes, breast milk is especially beneficial for preterm babies. Even if your baby can't nurse directly at first, pumping helps establish milk supply and provides important nutrients and antibodies.

When should I call my doctor about possible preterm labor symptoms?

Call immediately if you have regular contractions, pelvic pressure, back pain, or any change in vaginal discharge before 37 weeks. It's better to be checked unnecessarily than to miss true preterm labor.
