Can undigested grease cause acne?

I am currenty having issues with grease not always digesting that I am seeing a Dr. about. However I was curious if this could also cause acne? I never was one to get acne on my face nor front side though I did on my rear as well as my back.  Since my issue began I have noticed that I am getting alot of pimples on my face, neck, chest, shoulders and a couple in the southern region. Could my other issue cause this? I am not on any medication nor have I changed soaps.

How do you know that grease isn't digesting?  Are your stools greasy? Do they float?  If so, then you might have a problem with your liver or pancreas.  

As far as acne goes, lots of things can cause acne.  Be sure you mention all your issues to your doctor.
