There are many causes of preterm birth, such as cervical loosening during pregnancy, gynecological inflammations, underdeveloped uterus, congenital uterine malformations, and uterine fibroids, as well as pregnancy-related hypertension and diabetes, which can also lead to preterm labor. Additionally, carrying twins can increase uterine tension and potentially cause preterm birth. Other factors include long-distance travel, fatigue, emotional fluctuations, family relocation, abdominal trauma, prolonged standing, high psychological stress, advanced maternal age, and placental abruption during pregnancy, all of which can contribute to the occurrence of preterm birth.
