Premature birth, also known as preterm birth, is when a baby is born before the completion of the 37th week of pregnancy. A full-term pregnancy typically lasts 40 weeks. Premature birth can be a result of various factors, such as medical conditions in the mother, infections, multiple pregnancies, or lifestyle factors.
The causes of preterm labor are multifactorial and not always well understood. Some common risk factors include: multiple pregnancies (such as twins or triplets), infections, chronic diseases such as diabetes and high blood pressure, and a history of premature birth in a previous pregnancy. Lifestyle factors such as smoking, drug use, and poor prenatal care can also increase this risk. In some cases, preterm delivery is medically indicated for maternal or fetal health complications, and health care providers may need to intervene to protect the well-being of the mother and baby.
The consequences of premature birth can vary depending on the baby’s gestational age at birth and the presence of any underlying health problems. Premature babies often have problems with their underdeveloped organs, especially the lungs, and may require specialized care in the neonatal intensive care unit (NICU). While medical advances have greatly improved the survival rates of premature babies, they can still face long-term health problems such as developmental delays and learning disabilities. Prenatal care and careful monitoring by health care professionals are essential to identify risk factors and implement strategies to reduce the likelihood of preterm birth and improve outcomes for mothers and infants.
Premature babies may face a range of health problems, including breathing difficulties, feeding difficulties, infections, and developmental delays. The earlier the baby is born, the higher the risk of complications. However, with advances in medical technology and care, many premature babies survive and go on to lead healthy lives.
Prevention of premature birth can involve measures such as regular prenatal care, managing medical conditions, avoiding tobacco and substance use, and reducing stress. In cases where premature birth is unavoidable, medical interventions such as corticosteroids to promote lung development, antibiotics to prevent infections, and specialized neonatal care can help improve outcomes for the baby.
A newborn can be:
- Late preterm, born between 34 and 36 completed weeks of pregnancy.
- Moderately preterm, born between 32 and 34 weeks of pregnancy.
- Very preterm, born between 28 and 32 weeks of pregnancy.
- Extremely preterm, born before 28 weeks of pregnancy.
Most premature births happen in the late preterm stage.

Symptoms of premature labor
The symptoms of premature labor can include:
- Contractions: Regular contractions that occur every ten minutes or more frequently.
- Pressure in the pelvis: A feeling of pressure or heaviness in the pelvis or lower abdomen.
- Low backache: A constant or intermittent ache that is felt in the lower back.
- Increased vaginal discharge: An increase in vaginal discharge, particularly if it is watery or bloody.
- Menstrual-like cramps: Cramping that feels similar to menstrual cramps.
- Pelvic discomfort: discomfort or pain in the pelvic area. Pelvic health during pregnancy is one of the things that should be paid attention to.
- Ruptured membranes: If the amniotic sac ruptures, there will be a gush or trickle of fluid from the vagina.
Premature babies require special care in the neonatal intensive care unit (NICU) to support their growth and development until they are ready to go home. Here are some of the ways in which premature babies may receive specialized care:
- Temperature regulation: Premature babies have a hard time regulating their body temperature, so they are often placed in incubators or warmers to maintain a constant temperature.
- Feeding support: Premature babies may not be able to feed by mouth initially, so they may receive nutrition through a feeding tube or intravenously. A neonatal dietitian may be involved in creating an appropriate feeding plan for the baby.
- Breathing support: Premature babies may require respiratory support, such as oxygen therapy, mechanical ventilation, or non-invasive respiratory support.
- Monitoring: Premature babies may be monitored closely for signs of complications, such as infections, apnea (pauses in breathing), bradycardia (slowed heart rate), or jaundice.
- Developmental support: Premature babies may receive developmental support, such as physical therapy, occupational therapy, or sensory stimulation, to help them reach developmental milestones.
- Family-centered care: NICUs often provide family-centered care, which involves engaging and supporting parents in their baby’s care. This can include providing education, emotional support, and opportunities for parents to participate in their baby’s care.
Overall, the care of premature babies is multidisciplinary and involves a team of healthcare providers, including neonatologists, nurses, respiratory therapists, dietitians, and social workers, among others. The goal is to provide specialized care to help premature babies grow and develop, and ultimately go home healthy.

Risk factors and causes
Premature birth can be caused by a variety of factors, and some babies may be at a higher risk than others. Here are some of the risk factors for premature infants:
- Previous premature birth: Women who have previously given birth prematurely are at a higher risk of premature birth in subsequent pregnancies.
- Multiple pregnancies: Twins, triplets, or other multiples are more likely to be born prematurely.
- Medical conditions: Women with medical conditions such as high blood pressure, gestational diabetes, or infections may be at increased risk of preterm birth.
- Lifestyle factors: Smoking, drug use, and poor nutrition can increase the risk of premature birth.
- Cervical incompetence: Weakness in the cervix may cause it to open too early, leading to premature labor.
- Placenta problems: Placental abruption, where the placenta separates from the uterus too early, or placenta previa, where the placenta partially or completely covers the cervix, can increase the risk of premature birth.
- Uterine abnormalities: Women with uterine abnormalities, such as a bicornuate uterus or a septate uterus, may be at a higher risk of premature birth.
- In vitro fertilization (IVF): Women who conceive through IVF may have a higher risk of premature birth.
It is important to note that not all premature births are preventable, and some babies may be born prematurely for unknown reasons. However, by identifying and managing risk factors, healthcare providers can work to reduce the risk of premature birth and provide appropriate care for premature infants.
Premature birth can increase the risk of various complications for the newborn, including:
- Respiratory distress syndrome (RDS): This is a common complication of premature birth, where the baby’s lungs are not fully developed, making it difficult for them to breathe.
- Apnea: Premature babies may experience apnea, which is a temporary pause in breathing, and may require respiratory support.
- Intraventricular hemorrhage (IVH): This is bleeding in the brain, which can occur in premature babies due to the immature blood vessels in the brain.
- Patent ductus arteriosus (PDA): This is a condition where the ductus arteriosus, a blood vessel that connects two major arteries in the heart, does not close properly, which can lead to heart and lung problems.
- Retinopathy of prematurity (ROP): This is an eye condition that can occur in premature babies, where the blood vessels in the retina do not develop properly.
- Infections: Premature babies are at a higher risk of infections due to their underdeveloped immune system.
- Feeding problems: Premature babies may have feeding problems due to the immature functioning of the digestive system and swallowing.
- Developmental delays: Premature babies may be at higher risk for developmental delays, including delays in motor, Cognitive development, and language development.
- Cerebral palsy: Premature babies are at a higher risk of developing cerebral palsy, a group of disorders that affect movement and coordination.
The severity of these complications can vary depending on the gestational age of the baby and other risk factors. With appropriate medical care and support, many premature babies can overcome these complications and go on to lead healthy lives.
Prevention of premature birth can involve various measures, including:
- Regular prenatal care: Regular prenatal care can help identify and manage any medical conditions that may increase the risk of premature birth.
- Managing medical conditions: Women with medical conditions such as high blood pressure, diabetes, or infections should work with their healthcare providers to manage these conditions during pregnancy.
- Avoiding tobacco and substance use: Smoking, drug use, and alcohol consumption during pregnancy can increase the risk of premature birth and should be avoided.
- Reduce stress: High levels of stress during pregnancy may increase the risk of preterm labor, so finding ways to manage stress, such as pregnancy exercise,Relaxation techniques or yoga and meditation or counseling can be helpful.
- Managing cervical incompetence: Women with cervical incompetence may require cervical cerclage, a procedure where the cervix is stitched closed to prevent premature opening.
- Identifying multiple pregnancies: Identifying and managing multiple pregnancies early can help reduce the risk of premature birth.
- Avoiding unnecessary interventions: Avoiding unnecessary interventions during pregnancy, such as induction of natural labor or elective caesarean section, can help reduce the risk of premature birth.
- Preconception care: Women who are planning to become pregnant should receive preconception care to identify and manage any risk factors for premature birth.
