Gastritis means an inflammation of the lining of the stomach, that causes burning or sharp pain below the breast bone, accompanied with nausea, vomiting, belching, upper abdominal bloating, loss of appetite, feeling full after eating small amounts of food.
Changes of the stomach lining due to stomach inflammation can be seen by performing upper endoscopy.
Diverticulum is a small bulging sac pushing outward from the wall of a hollow organ in the body.
Diverticulum and plural diverticula are usually located at the wall of large intestine, but, they may be present in the upper part of small intestine (ex.congenital diverticulum known as Meckel's diverticulum) and at the wall of stomach, known as gastric diverticula.
Usually, doesn't cause symptoms, but when is symptomatic, the patient can feel vague pain under the breast bone, early satiety, and sometimes may bleed resulting in vomiting blood and blood in the stool.
The stomach diverticulum can be diagnosed by performing upper endoscopy, too.
A temporary, mild throat irritation sometimes occurs after the exam.
It is an expectable side effect from this procedure.
