Duodenum is the first part of the small intestine that immediately follows the stomach. Hence tumors in duodenum cause obstruction to the food pathway resulting in vomiting and other symptoms such as:
- Abdominal Pain
- Nausea and vomiting
- Weakness and fatigue
- Unexplained weight loss
- Blood in stools or altered coloured stools
- Blood in vomit
- Anemia due to chronic blood loss
- Jaundice due to obstruction of bile duct
