How does maternal obesity influence the risk of shoulder dystocia?

Maternal obesity significantly contributes to fetal macrosomia, which refers to an excessive fetal size often due to increased maternal weight and health conditions associated with obesity, such as gestational diabetes. When a fetus is larger than average, it increases the likelihood of complications during delivery, including shoulder dystocia, where the shoulders cannot easily pass through the mother’s pelvis during childbirth.

The connection between maternal obesity and shoulder dystocia is substantial, as the larger fetal size associated with maternal obesity can lead to difficulties in delivery. This results in a higher chance of obstructed labor when the shoulders become lodged. Therefore, recognizing maternal obesity as a risk factor for shoulder dystocia is crucial for healthcare providers to prepare adequately for potential delivery complications and to implement strategies to mitigate risks for both the mother and the fetus.
