Why does my feces contain yellow, capsule-shaped matter in

Customer Question

Why does my feces contain yellow, capsule-shaped matter in it? It has been in there for at least 3 days. When I take one out (with gloved hands) and clean it up, I see it has a tough, yellow membrane. It seems to be pretty thick for a membrane. Inside, it is filled with white matter. There is no foul odor. I have not eaten anything that this would be.

Your age, gender, medical conditions/meds? Do you eat a lot of fatty foods? Bowel movements are otherwise normal?
Customer: replied 8 years ago.
I am a 54 year old female. I have diabetes, hypertension, both treated and well-controlled. I do not eat a lot of fatty foods. My bowell movements are otherwise about the same as usual. I am feeling somewhat ill, more so today than yesterday.

I take: metformin, simvastin, zoloft, Wellbutrin XL, Actos, lorezepam, Hyzaar, Protonix (for GERD). I am presently on a Medrol Dose Pak for arthritis in the knee, and just took my first Celebrex today for that condition. I have been on these meds for several years, except for the metformin, Actos, Medrol, and Celebrex. I have taken Medrol and Celebrex in the past. I have never had this happen to me before;.

OK. This may not be anything serious, but the first thing I would do is get a stool sample for microscopic and culture, and, depending on the results, either treat you myself or refer you to a gastroenterologist for evaluation and possible scoping. Diagnoses include bacterial/parasitic infections, malabsorption syndrome, steatorrhea, celiac disease, and pancreatic insufficiency.

Are these the only things that would cause such a problem? And, how would I do a stool sample and treat myself?
Customer: replied 8 years ago.
I don't see your last answer, although I received a notification that you had answered.
Expert:  Dr Chip (M.D.) replied 8 years ago.
Sorry--I'm back. There are, of course other differential diagnoses, but these are the first I would suspect. As I said, this may not be serious, but it needs to be checked out. You yourself couldn't properly evaluated your stool. I would say, if the problem clears up in a few days and doesn't recur, you probably have nothing to worry about.
Customer: replied 8 years ago.
I have done a quick research on the reasons you have given, and none of them say anythying about these yellow masses. They are as large as a large capsule of medication. They are not tiny, and they are very noticable. I would think it was either my meds not digesting properly, (in which case I would not be getting the benefit of it) or something like that. It is not anything I have eaten. It is not frothy, foul smelling, etc., etc. It is a separate part of the stool. The stool is loose, and in it are these capsule-like items. I am not sure if I had made that clear before.
Expert:  Dr Chip (M.D.) replied 8 years ago.
are any of the meds you've listed something you took for the first time, and then this occurred in a day or two? Were any of the new pills the same color as the globs in your stool?
Customer: replied 8 years ago.
No, none of the meds I take are that color. The only ones that large are the ones I have taken for a while, and that would be meformin and Wellbutrin LX. I have taken Wellbutrin XL for several years now, and metformin since January. All the other tablets are much smaller and shaped differently.
Expert:  Dr Chip (M.D.) replied 8 years ago.
Well, It's unlikely that this would suddenly happen from meds you've taken for so long. The question would still be, if it were, why are they suddenly not being digested properly? I'd still do what I've suggested if you were my patient.

Well, thank you. I am sorry that I don't have any more real answer that I did when we started. I will contact my family doc tomorrow. Have a great day!

I don't see a reply, though I did receive an email that I have one.
