Abstract
Roy andSil~er~ann (1982) stated that, diarrhea may
be cefined as water and electrolytes mal-absorption leadin~
to accelerated excretion of intestinal contents
Diarrhea is sometimes difficult to define in terms of
numbers or consistency of stools because there are wide
variations t_n colonic functions. Some infants may pass
one firm stool every second or third day, whereas other
may have 5-8 soft small stools daily. They mentioned
that, a gradual or sudden increase in the number of stools
a reduction in their £irm consistency, coupled with an
iL:rease i~ their fluid contents, or a tendency for the
stool to be greer. are i~portant factor~ for diagnosis of
diarrhea.
