what can cause premature delivery
There are a number of other risk factors for premature labour and delivery. Some of these risks, such as anemia, slow maternal weight gain, stressful work habits, smoking, drinking alcohol, and using drugs like cocaine, can be rectified during pregnancy.
The causes of preterm labor and premature birth are numerous, complex, and only partly understood. Medical, psychosocial, and biological factors may all play a role in preterm labor and birth. There are three main situations in which preterm labor and premature birth may occur: Spontaneous preterm labor and birth.
The cause of preterm birth is often not known. Risk factors include diabetes, high blood pressure, being pregnant with more than one baby, being either obese or underweight, a number of vaginal infections, tobacco smoking, and psychological stress, among others.
