Respuesta :
A hiatal hernia is a protrusion of a portion of the stomach through the diaphragm.
Hiatal hernia is a condition which arises due to a rise in blood pressure. In this condition the stomach bulges up through an opening in the diaphragm. This condition interjects with the normal mechanism of reflux that occurs through the sphincter, which is present in the esophagus. This condition usually occurs when there is excessive pressure around the stomach due to activities like repeated vomiting. This condition is usually not fatal, however, in rare and serious cases this condition can effect the esophagus and cause esophageal cancer. This condition can also lead to leakage of stomach acids and cause ulcers in the alimentary canal. In serious cases of hiatal hernia the blood flow to and from the intestine can also be effected. Serious cases need surgical treatment.
