How Is Each Type of Crohn's Disease Different?

Gastroduodenal Crohn’s disease causes inflammation of the abdomen and the duodenum, which is the first part of the small intestine. Symptoms of this type of Crohn’s disease include nausea, loss of appetite, and weight loss. If the thin segments of the bowel become blocked due to intestinal inflammation, it can lead to complications such as bloody vomiting. It may be difficult to differentiate gastroduodenal Crohn’s disease from other conditions such as gastritis, stomach ulcers or gastroesophageal reflux disease.
