Gastrointestinal Disorders

All diseases that pertain to the gastrointestinal tract are labelled as digestive diseases. This includes diseases of the esophagus, stomach, first, second and third part of the duodenum, jejunum, ileum, the ileo-cecal complex, large intestine (ascending, transverse and descending colon) sigmoid colon and rectum.

Upper GIT Disease

• LES – (Barrett's esophagus)
• Esophageal motility disorder – (Nutcracker esophagus, Achalasia, Diffuse esophageal spasm, GERD)
• Esophageal stricture
• Megaesophagus

Stomach

• Gastritis – (Atrophic, Ménétrier's disease, Gastroenteritis)
• Peptic (gastric) ulcer – (Cushing ulcer, Dieulafoy's lesion)
