What does it mean to have a maturity level 2 at 35 weeks?

Under normal circumstances, a lung maturity level of 2 at 35 weeks indicates that the placenta has matured. The detailed analysis is as follows:

During fetal development, lung maturity is an important indicator. The lung maturity grade determines whether the fetus can breathe normally and adapt to the external environment after birth. Lung maturity is typically assessed using standards established by the American College of Obstetricians and Gynecologists (ACOG), among which "maturity level 2 at 35 weeks" is one classification. A lung maturity level of 2 at 35 weeks suggests that the fetal lungs have achieved a certain degree of maturity, but further development and maturation are still required for full adaptation to the external environment. This means that the production and secretion of key substances such as pulmonary surfactant remain insufficient. Fetal lung development is a progressive process, usually reaching full maturity only in the late stages of pregnancy. Although a 35-week fetus is relatively close to full maturity compared to preterm infants, additional time for further development is still needed.

In the third trimester, pregnant women should pay special attention to their own health and the well-being of the fetus. It is important to maintain a balanced diet and adequate intake of essential nutrients. Increase consumption of protein, calcium, iron, and folic acid, while avoiding excessive caffeine and processed foods.
