What is the length of the cervical canal during pregnancy?

Pregnant women should pay attention to their bodies during pregnancy to avoid other problems that may cause dangerous situations for pregnant women, especially some abnormal physical phenomena of pregnant women. If these problems occur, they should pay attention to timely treatment to ensure good health. So what is the length of the cervical canal of pregnant women? Let me introduce the length of the cervical canal to you below.

Cervical length: It is a convenient way to prevent premature birth. Obstetricians usually use B-ultrasound to understand the length of a pregnant woman's cervix within 22-24 weeks. If the cervix is ​​longer than 30 mm, premature birth will generally not occur and it is considered normal. However, if it is shorter than this value, especially shorter than 25 mm, it indicates a higher possibility of premature birth.

The cervical canal does not have a fixed length after pregnancy. It will gradually become thinner and shorter as the months go by. It will open when you give birth, and the baby can be born when it opens to 10 finger widths.

Problem Analysis: Hello, considering your situation, you are now in your 21st week of pregnancy and the length of the cervical canal is 32mm, which is normal and you don't need to worry about it.

Suggestions: The cervix is ​​located in the lower part of the uterus, is approximately cone-shaped, 2.5 to 3 cm long, with the upper end connected to the uterine body and the lower end deep into the vagina. It is a normal part of the human body. If the cervical canal is shorter than 25mm, you should consider cervical insufficiency, which may make you more prone to miscarriage or premature birth. Your situation is normal and does not pose any harm to the fetus, so you can rest assured.

Obstetricians usually use B-ultrasound to understand the length of a pregnant woman's cervix within nine months of pregnancy. If the cervix is ​​longer than 30 mm, premature birth generally will not occur; but if it is shorter than this value, especially less than 25 mm, it indicates a greater possibility of premature birth.

The above is my opinion on this issue. If the patient has the above problems, he/she should pay attention to timely treatment to ensure good health, avoid problems with the length of the cervical canal, which will affect the health of the pregnant woman, and also avoid affecting the health of the fetus.
