Hello, Thank you for asking your question at healthcare magic I understand your concern, but at this point I cannot give you a definite answer. I would like to know more about your history like -When did the symptoms start -Any yellow discoloration of skin along with itching -fever -abdominal pain -are you currently on any medication -history of alcohol use, drug use -weight loss,lack of appetite -history of exposure to hepatitis The symptoms of oily greasy stool and skin itching, raises the possibility of increased bile salts circulating in blood which occurs due to blockage in flow in bile from liver to intestine.There are several causes for this including Hepatitis (due to viruses,medication,alcohol etc) , Gall stones , diseases causing blockage of biliary tree like primary biliary cirrhosis.primary sclerosing cholangitis , cancer . But a detailed history, physical examination and investigations are required to come to a definitive diagnosis. I recommend that you consult your doctor for complete evaluation. Hope I was able to help you, Please feel free to address any more concerns, Regards, Dr.Lekshmi
