Multiple Choice

Which of the following correctly matches the digestive disorder with its description and/or cause?

Celiac disease - caused by a bacterial infection in the stomach

Gastroesophageal reflux disease (GERD) - caused by the backflow of stomach acid into the esophagus

Irritable bowel syndrome (IBS) - caused by a viral infection in the intestines

Peptic ulcer - caused by excessive fiber intake

Verified step by step guidance

Begin by identifying the digestive disorders listed: Celiac disease, Gastroesophageal reflux disease (GERD), Irritable bowel syndrome (IBS), and Peptic ulcer.

Understand the causes and descriptions of each disorder: Celiac disease is an autoimmune disorder triggered by gluten, GERD is caused by the backflow of stomach acid into the esophagus, IBS is a functional gastrointestinal disorder with no specific cause, and Peptic ulcers are often caused by Helicobacter pylori infection or NSAID use, not excessive fiber intake.

Match each disorder with its correct description or cause: Celiac disease is not caused by a bacterial infection, GERD is correctly described as caused by stomach acid backflow, IBS is not caused by a viral infection, and Peptic ulcers are not caused by excessive fiber intake.

Recognize that the correct match from the options provided is GERD - caused by the backflow of stomach acid into the esophagus.

Conclude that understanding the specific causes and descriptions of digestive disorders is crucial for accurate diagnosis and treatment.
