Question

Quizplus · Accepted Answer

Acid reflux occurs when the gastroesophageal sphincter, which usually prevents stomach acid from flowing back up into the esophagus, fails to close properly. Peptic ulcers usually form in the stomach or duodenum (the first part of the small intestine), not in the large intestine. Vomiting blood is a symptom of a more serious condition, such as a bleeding ulcer or cancer, not irritable bowel syndrome. There is no established link between H. pylori infection and type 1 diabetes.
