IRRITABLE BOWEL SYNDROME:

DEFINITION: The cause of irritable bowel syndrome is
unknown.  Although often called "colitis", it is not an
infection or inflammatory condition.

SYMPTOMS: Symtoms vary, but can include periodic abdominal
cramping, migratory abdominal pains, diarrhea, or
constipation.  Commonly, a few days of constipation is
followed by loose stools, then constipation begins again. 

DIAGNOSITIC TESTING: There is no specific test for
irritable bowel syndrome.  The disease is diagnosed by 1)
history and exam findings, and 2) finding no evidence of
other disease.  It is common for physicians to order a
barium enema xray or do a colonscope to get a clear cut
understanding of this disorder.

THERAPY: Irritable bowel syndrome is treated by making the
stool softer and bulkier.  Regular meals which include
plenty of soluble fiber help.  Avoid foods which provoke
cramping.  Stool "bulking agents" such as metamucil help. 
Occasional flare-ups are expected.  

IF PROBLEMS: Call the physician if symptoms worsen -- such
as severe or constant abdominal pain, fever, blood in the
stool, increasing constipation, or more frequent or severe
diarrhea.
