Hi, thanks for using healthcare magic
Oily stools usually indicate an increased amount of fat in the stool.It could be related to a number of different circumstances such as (1) liver
disease (2) gall bladder disease
(3) side effect of medication (4) as a complication of conditions that cause poor absorption of fat such as inflammatory bowel disease
(5) bacterial overgrowth in the intestine (6) high thyroid
The above are only some of the potential causes for oily stool.
You may want to, if possible, visit your doctor who may request a stool sample after taking your history and conducting a general examination.
Further tests and treatment will depend on the results.
I hope this helps
