Prevention

You can't prevent an incompetent cervix — but there's much you can do to promote a healthy, full-term pregnancy. For example:

• Seek regular prenatal care. Prenatal visits can help your doctor monitor your health and your baby's health. Mention any signs or symptoms that concern you, even if they seem silly or unimportant.
• Eat a healthy diet. During pregnancy, you'll need more folic acid, calcium, iron and other essential nutrients. A daily prenatal vitamin — ideally starting a few months before conception — can help fill any dietary gaps.
• Gain weight wisely. Gaining the right amount of weight can support your baby's health. A weight gain of 25 to 35 pounds (about 11 to 16 kilograms) is often recommended for women who have a healthy weight before pregnancy.
• Avoid risky substances. If you smoke, quit. Alcohol and illegal drugs are off-limits, too. In addition, get your doctor's OK before taking any medications or supplements — even those available over-the-counter.

If you've had an incompetent cervix during one pregnacy, you're at risk of premature birth or pregnancy loss in later pregnancies. If you're considering getting pregnant again, talk with your doctor to understand the risks and what you can do to promote a healthy pregnancy.
