Hi, Having frothy yellow stools is known as steatorrhea. This is a condition due to several causes and it leads to discomfort for the patient. I am going to list the causes of steatorrhea. If you like you can go through each and then see which one fits you the best. Pancreatitis (acute or chronic) Pancreatic cancer Celiac disease Inflammatory bowel disease, particularly Crohn’s disease Diarrhea Possibly irritable bowel syndrome (diarrhea-predominant IBS) Short bowel syndrome Excessive use of laxatives Small bowel bacterial overgrowth Abetalipoproteinemia Whipple’s disease Other causes of pancreatic enzyme deficiency (exocrine insufficiency) Gallstones, particularly bile duct stones Primary sclerosing cholangitis Zollinger-Ellison syndrome These are all the causes of yellowish fatty liver. Since you have prolapsed bowel as well, I think you are getting fatty stool because of that. Dr Vineet
