A hiatial or hiatus hernia occurs when the stomach protrudes through a weakened portion of the diaphragm, a large muscle that separates the abdominal and chest cavities. Patients who develop gastroesophageal reflux disease, or GERD, or have a strangulated hiatal hernia may require surgical treatment, according to the Cleveland Clinic 2. Before undergoing surgery, patients should discuss the potential complications of hiatal hernia surgery with a medical professional.

Difficulty Burping or Vomiting

Hiatal hernia surgery can cause burping or vomiting complications in patients. Affected patients can experience difficulty or an inability to burp or vomit after undergoing this surgical procedure, Dr. J. Scott Roth with the University of Kentucky warns. Consequently, patients can feel unusually bloated after eating. Typically, these complications of hiatal hernia gradually subside as a patient begins to heal from hiatal hernia surgery; however, in certain patients, these complications can be chronic.

Painful Swallowing

Painful swallowing, a complication of hiatal hernia surgery called dysphagia, can occur in certain patients, Drugs.com warns.
