Good grief, is nothing sacred on this site? People seem to happily discuss all their medical problems with fellow posters when they would be better contacting their GP. End of rant.
Depends what you mean by diarrhea.
Yes.....if does....the colour of loose stools may well be an indicator of probable cause......e.g yellowish....Pancreatic disease......pale loose stools....gall bladder disease.....watery stools...food poisoning and so on and so on........very important diagnostic symptom.
The reason I was asking about colour was that I had two bouts of illness.
The first, diagnosed and treated as dysentery, produced a totally different colour from the second bout. The second bout was undiagnosed.
