Question 3

Question 5

hello, i recently started taking probiotics, and now i am having small white clumps in my stool. i stopped using the probiotics and am still noticing?

Accepted Answer

Unusual: That's unusual. What led you to take a probiotic? Most likely the stool abnormality is from something other than the probiotic. If it persists more than a week or 2 then a medical exam would be reasonable.

Question 6

i used to eat ~1 cup of yogurt/day but stopped recently. for the last few weeks i've had loose stools 1x/day. is this related due to probiotics?

Accepted Answer

Could be: a lot of things. Mostly the calcium and lack of fiber in yogurt is more likely. The probiotics is a bit tricky because most commercial yogurt isn't that good on quality control of the living bacteria.
Without an actual examination, I cannot give specific medical advice on your particular health,

Question 10

stools look normal now, still smell really weird. been off flagyl abt a month. but smell started before then anyway. yogurt for probiotics didn't help?

Accepted Answer

Needs recheck: Metronidazole or Flagyl is normally used to treat Clostridium difficile colitis, Which is an opportunistic infection, usually caused by antibiotic usage.  However, there are other causes of infectious diarrhea other than Clostridium difficile colitis.  For persistent diarrhea, additional tests maybe needed, including fecal leukocytes, stool ova and parasite tests.  Consult physician may be needed.
