Symptoms of a stomach hernia, also known as a hiatal hernia, include heartburn, belching, chest or abdominal pain and difficulty swallowing, states Mayo Clinic. Other symptoms include feeling full after meals, vomiting blood and passing black stools. Individuals with small hiatal hernias may experience no signs or symptoms.
A stomach hernia occurs when part of the stomach pushes upward toward the diaphragm, according to WebMD. Most people with small stomach hernias never know they have an issue because it won’t cause any serious problems, and they only find out about the problem when their doctor is checking for another condition.
When a large hiatal hernia is present, individuals may experience a lot of discomfort, mostly because the hernia causes food and acid to back up into the esophagus, states WebMD. This is why heartburn is so common in these types of hernias.
Those who experience stomach hernia symptoms need to visit a doctor for further examination. Even in a hiatal hernia cases where no symptoms are present, a serious condition, known as a paraesophageal hernia may be developing, according to WebMD. This is where part of the stomach squeezes through the hiatus landing next to the esophagus. This type of hernia puts the stomach at risk of having its blood supply shut off and is a very serious condition that requires immediate medical attention.
