Which of the following organs is affected in gastro-oesophageal reflux disease (GERD)?

Which of the following organs is affected in gastro-oesophageal reflux disease (GERD)? Correct Answer Lower oesophageal sphincter

Concept:

  • Gastro-esophageal reflux disease -> It is a disease characterised by frequent regurgitation of the stomach contents into the esophagus.
  • The acidic nature of the gastric reflux often irritates the esophageal epithelium.
  • Lifestyle changes can be done to manage and prevent GERD.

Explanation:

  • Once the food is ingested from the mouth through peristalsis, the esophageal sphincter closes and prevents the movement of the food back towards the oral cavity.
  • In case of GERD, gastric reflux regurgitates into the esophagus and damages the esophageal lining.
  • Improper functioning of the lower esophageal sphincter leads to GERD.

Additional Information

  • Duodenum is not affected in GERD as it lies below the stomach in the alimentary canal.
  • Diaphragm is not affected in GERD
  • Pylorus is not affected by GERD.
