OS Tightening

blog

OS tightening or cervical cerclage is a surgery done when a pregnant woman’s cervix is weak and there’s a chance of premature childbirth as the cervix is likely to shorten or open too early. To prevent premature labour, os tightening is done to help a developing baby stay inside the uterus until 37 to 38 weeks of pregnancy. In this procedure, the cervix is stitched closed under anesthesia. The surgery is either done through the vagina (common) or through the abdomen.
