Hi, I am a 47 year old female, with a BSN degree, with no major health issues except I am on 2 antidepressants (very long term) and a few psychiatric meds. I never eat more then once a day sometimes not even that as I am Extremely Picky. I eat no meat, fish, or poultry. I have had LONG TERM severe constipation, not relieved by Miralax, Colace, fiber etc. Over the past few months, when I do have a relatively "normal stool" instead of my customary "hard tiny pieces or balls" I have noticed yellow or orange oil floating to the top of the water in the commode. I attributed this to eating frozen pizzas & mac. & cheese (fatty foods) but now have read it can be a sign of Cystic Fibrosis, or celiac disease. I am now worried! Thank You.
