Hello! Thank you for the query. Yellowish urine is a normal thing, however stool should be rather brown. You need to know that stool has its color thanks to bile secretion into it (bile is yellow) and bile digestion by intestinal bacteria (which make bile brown). So your symptoms and stool color are most likely caused by lac of good bacteria in the intestines which most likely have been replaced by pathological bacteria. This is the first issue which should be checked. If intestines infection wont be present, chronic pancreatitis should be also considered. I suggest you to start with blood work, liver tests, pancreas tests and stool tests. Please discuss with your doctor Rifaximine treatment. You should also start probiotic supplementation. Hope this will help. Regards.
