Which term describes the reflux of stomach contents into the esophagus?

• A. Ischemia
• B. Hemophilia
• C. Gastroesophageal reflux disease
• D. Prothrombin deficiency

Answer: (C)

Reflux of stomach contents into the esophagus is described by the term gastroesophageal reflux disease. This names the condition in which stomach acid frequently flows back into the esophagus due to a weak or transiently relaxing lower esophageal sphincter, leading to symptoms such as heartburn and regurgitation. The other terms refer to different health issues: ischemia is reduced blood flow to tissue, hemophilia is a bleeding disorder, and prothrombin deficiency is a clotting factor deficiency.
