How to check the length of the cervix

Many female friends who are pregnant for the first time want to know more about pregnancy health care knowledge. For example, the length of the cervix will change significantly during delivery, and this is also pregnancy health care knowledge that most pregnant women do not know. So how do you check the length of the cervix of a pregnant woman?

The length of the cervical canal is usually checked by abdominal B-ultrasound, and most cervical canal lengths are limited to 3 cm. Moreover, the length of the cervical canal has no direct relationship with pregnancy, but is related to whether the inner edge of the cervix is ​​damaged. This is also the main purpose of prenatal cervical canal examination.

There is acquired damage to the inside of the cervix, or congenital malformation, such as cervical laceration during delivery, which in turn damages the internal cervical os, as well as multiple abortions and cervical dilation treatments that cause cervical lacerations, which can easily lead to cervical insufficiency. If you suffer from cervical insufficiency, it will often lead to miscarriage.

Therefore, cervical insufficiency requires necessary cervical cerclage. If a woman is diagnosed with cervical insufficiency, and after examination, a No. 6 dilator is found to be able to pass through the internal os of the cervix, it can be basically confirmed that she has cervical insufficiency. In this case, cervical cerclage should be performed around 15 or 16 weeks of pregnancy, and it should be combined with daily care to protect the fetus, avoid excessive exercise and fatigue, and prevent miscarriage, so as to ensure the healthy development of pregnancy.

When should pregnant women check the length of their cervix?

In general, it is recommended that pregnant women use B-ultrasound to check the length of their cervix after 20 weeks of pregnancy. The normal length of the cervix should be more than 2.5 cm. If the cervix is ​​too short, you need to pay attention. If necessary, you may need to undergo cervical ligation to prevent accidental miscarriage. If the pregnancy exceeds 28 weeks, this type of surgery is not recommended. At this time, you can choose to maintain the fetus.

Not all pregnant women need to check the length of their cervix. This examination is generally for pregnant women with a history of congenital miscarriage or miscarriage due to a short cervical canal. This examination can prevent them from having accidents again and has the effect of protecting the fetus.

During pregnancy, you must strictly control your diet. Many foods cannot be eaten, such as chili peppers and overly sweet foods. These foods are very harmful to pregnant women and will stimulate the growth of the fetus. Overly sweet foods will also cause gestational diabetes in pregnant women and the fetus will also develop macrosomia. In severe cases, it will cause dystocia in pregnant women. You need to pay attention to it from the early stages of pregnancy.
