This condition develops when part of your stomach pushes up through an opening in your diaphragm called the “hiatus.” The diaphragm separates your chest from your abdominal cavity. The hiatus is the opening that your esophagus passes through.
Causes and Risk Factors
If the muscle tissue around your hiatus is not strong enough, or if your hiatus is abnormally large, a hiatal hernia can form. It can be caused by lifting heavy objects. It can be caused by coughing or by straining when you move your bowels. It can be caused by injury. It can also develop because of a problem with the structure of your diaphragm. Obesity increases your risk for this type of hernia. It is also more common in people who are older.
Symptoms may include heartburn and chest pain. You may have difficulty swallowing, and you may belch. You may feel uncomfortably full after you eat a meal. You may also have bleeding in your digestive tract. This can cause you to vomit blood. You may pass stools that appear black
