9. Nausea and vomiting
The pancreas is also responsible for the creation of digestive enzymes that help process food properly. Digestion is disrupted when cancer invades the pancreas, leading to discomfort upon eating due to bacterial overgrowth in the lower GI tract.
Tumors may also press on the stomach and partially block it so that food can’t pass as necessary. All of this digestive upheaval is likely to come with nausea and vomiting, or at the least, heartburn and acid reflux.
