Causes and Risk Factors
The actual causes of IBS are not
yet clear, but a clinical research
shows that IBS is the result of
abnormal colon motility. Colon
motility refers to the contraction
of intestine muscles and movement
of its contents toward the rectum
and anus. When the intestine muscles
contract very tightly, it results
in frequent, quick movement of
the food through the intestines
leading to diarrhea. The opposite
may also happen, leading to constipation
and painful, difficult bowel movements.
Stress,
emotional conflicts, or nervous
system problems are also associated
with the conditions of impaired
colon motility. This suggests
that weakened control over the
bowel movement sensation and muscle
contraction may aggravate the
symptoms of IBS.
