👉 Hemiascis is a medical condition that involves a hernia in the stomach or intestine. It occurs when part of the stomach or small intestine is pushed out through an opening called a "hernial sac" into the abdominal cavity. This can be caused by many different factors, such as trauma, infection, or obesity. Hemiascis can cause pain and discomfort, nausea, vomiting, and other symptoms. Treatment options may include surgery to repair the hernia or improve its location.
