Introduction

At 12 weeks of pregnancy, the placental thickness generally does not exceed 2 centimeters. At this stage, the placenta has just formed and usually measures about 1 centimeter in thickness. As gestational age increases, placental function gradually matures, and both the thickness and size of the placenta increase accordingly. During the second trimester, placental thickness typically remains under 2 centimeters. By the end of pregnancy, the placental thickness usually reaches 3 centimeters.

In daily life, many people like to have regular health checkups to monitor their well-being. Pregnant women often pay attention to the thickness of their placenta. So what is the normal placental thickness at 12 weeks of pregnancy?

Normal Placental Thickness at 12 Weeks of Pregnancy

At 12 weeks of pregnancy, placental thickness should not exceed 3 centimeters. At this stage, the placenta has just formed and typically measures about 2 centimeters in thickness. As gestational age increases, placental function gradually matures, and both the thickness and size of the placenta increase accordingly. During mid-pregnancy, placental thickness is usually less than 2 centimeters. In later stages of pregnancy, it commonly reaches up to 4 centimeters. By late pregnancy, placental thickness generally does not exceed 6 centimeters. Abnormal placental thickness may indicate structural abnormalities and should prompt evaluation for conditions such as chorionic hemangioma or intrauterine infection.

The placenta consists of fetal components (amnion and chorionic villi) and maternal components (decidua basalis). The amnion is a translucent membrane attached to the fetal side of the placenta. Placental thickness reflects the thickness of the villous chorion, normally ranging between 1 and 3 centimeters. Through the placenta, the fetus absorbs nutrients from the mother to support healthy growth and development.

It's important to maintain good self-care, enhance immunity and resistance, ensure balanced nutrition, and pay attention to diet to prevent illness. If any abnormalities occur, seek timely medical examination and treatment. We hope this information helps. Wishing you good health and a happy life!
