Changes in stool (feces) color are often harmless and reflect dietary influences.
Certain persistent changes in stool color are characteristic for specific conditions:
- black, foul-smelling stool: intestinal bleeding (typically from the stomach and upper small intestine) due to ulcers, tumors; ingestion of iron or bismuth
- maroon stool: intestinal bleeding (from the middle intestine or proximal colon) due to ulcers, tumors, Crohn's disease, ulcerative colitis
- clay-colored stool: lack of bile due to blockage of the main bile duct
- pale yellow, greasy, foul-smelling stool: malabsorption of fat due to pancreatic insufficiency, as seen with pancreatitis, pancreatic cancer, cystic fibrosis, celiac disease
As such, yellow stool does not necessarily indicate pancreatic cancer, please consult your doctor and have tests to determine it.
