There are several potential causes for difficult labor:
Pelvic issues: A narrow or abnormally shaped pelvis can make it hard for the baby to pass through the birth canal. Abnormal fetal position: If the baby is not in a head-down position, it can complicate the delivery process. Uterine contractions: Weak or irregular contractions may not effectively dilate the cervix or move the baby down the birth canal. Large baby (macrosomia): A larger-than-average baby can make vaginal delivery more difficult.
