Please explain what does a hiatal hernia do to your body?

Most asymptomatc: Most hiatal hernias are asymptomatic. When symptoms occur, they are usually reflux, burning and regurgitation. Large hhs can cause pain after eating, fullness, vomiting. Rarely hiatal hernias require emergent repair if they volvulize (twist). A volvulus could cause the the stomach to lose its blood supply and necrose (die). A surgeon can help evaluate a hh and determine if it needs repair.

Hiatal hernia : A hiatal hernia is when the diaphragm that surrounds your esophagus as it passes from your chest to your abdomen is not tight but is loose. This allows acid reflux to occur. If the hernia is large, it can also allow your stomach to slide into your chest and cause more discomfort.
