The herniation through the diaphragm is most commonly found on which side?

Herniation through the diaphragm, particularly a diaphragmatic hernia, commonly occurs on the left side. This is primarily due to anatomical considerations, such as the presence of the liver on the right side, which provides some protection against herniation. The left side of the diaphragm has less structural support from adjacent organs, making it more susceptible to herniation. Furthermore, there are specific medical conditions and developmental factors that can lead to herniation on this side, including congenital issues like a Bochdalek hernia. Understanding these anatomical differences is crucial for diagnosing and treating cases of diaphragmatic hernia effectively.
