How big is 3 cm haital hernia?

A 3 cm hiatal hernia is relatively small, as hiatal hernias can range from a few millimeters to several centimeters in size. This type of hernia occurs when part of the stomach pushes through the diaphragm into the chest cavity. While a 3 cm hernia may not cause significant symptoms for some individuals, it can still lead to issues like acid reflux or discomfort in others. It's essential to consult a healthcare provider for proper evaluation and management.
