What Causes Odorless Bowel Movements?
Blood can be from hemorrhoid or from infection
Detailed Answer:
Dear patient,
The stools need not stink all the time, it can be odorless too. Odorless stools suggest non-infection or just a simple viral diarrhea.
The blood is not necessarily dangerous, can be from a hemorrhoid. Another possibility is that, in addition to IBS, you could have a bacterial or viral infection (gastroenteritis) which sometimes causes watery stools also and would be self healing within a few days.
I suggest wait and see first, only if this gets worse or high fever, strong pain or larger amounts of blood in stool reoccur there should be an examination by your local GP.
Until then try the usual things that help you, which can be local warmth, cumin ginger tea or similar.
Hope this is helping you , if you have any clarifications you can get back to me, if this was helpful please kindly rate my answer. Best regards
