12) Obstruction
A stomach ulcer located at the end of the stomach (antral area) can cause sphincter or intestinal obstruction. It is due to inflammation or scarring of the stomach ulcers in the antrum that can narrow or close the intestinal lumen. It prevents food to move from your stomach into the duodenum. This further leads to the accumulation of food in the stomach, resulting in vomiting the food contents and acid. The vomiting that results from stomach or intestinal obstruction is called “projectile vomiting” as it ejects the gastric contents with great force.
