Nausea followed by bouts of vomiting is common to pancreatic cancer patients as the disease progresses—especially if a pancreatic tumor has grown so large that it blocks a portion of the digestive tract, causing inefficient and uncomfortable food digestion. Heartburn and acid reflux can also occur, which can cause a burning sensation in the throat following vomiting.
In most cases, severe nausea and vomiting will not occur until the disease has reached a relatively advanced stage. However, because pancreatic cancer is one of the most difficult types of malignancies to detect, patients may not experience severe health problems until tumors reach a sizable proportion. Nausea and vomiting are typically accompanied by rapid, unexplained weight loss and diminished appetite, and all these symptoms have a related cause: impediments in the abdomen, usually localized around the duodenum, which interfere with normal digestion and excretion processes.
