Nausea and vomiting
It counts as one of the initial symptoms patients report in pancreatic cancer. It typically results from an alteration to the digestive system because the pancreas has a primary function to counter the acid from the stomach. Additionally, patients with pancreatic cancer have a delayed gastric emptying, which means their stomach is very slow in passing food to the first portion of the small intestines. When the tumor becomes larger, it would also create a mechanical force against the stomach, pushing the organ and increasing nausea and vomiting.
