Premature labor

Premature labor means babies born before 37 weeks of pregnancy. It accounts for about seven percent of total babies born. It is high in women who smoke and in those who are under weight

The causes of premature labor are not clear with 40 percent of cases. The main causes include:

  • Pre-eclampsia Antenatal hemorrhage Multiple pregnancies
  • Fetal abnormalities or death
  • Cervical incompetence
  • Illnesses like diabetes, high blood pressure or heart disease in the mother
  • Stress has shown to induce labor, especially when it is sudden or severe.
  • Many vaginal infections like gonorrhoea, trichomoniasis, Chlamydia, and group B streptococci are considered to be associated with premature labor.
  • Bacterial vaginosisin, in which the acidity of the vagina is changed, is also linked with premature labor. This could be possible due the reduction of the natural defenses of the body against infection.
