Abstract
Chronic abdominal pain is a very common condition all over the world.
Although not expected to present emergently, acute exacerbations of chronic pain or
the slightest change that worsens the patient's condition (e.g, acute-onset diarrhea,
vomiting, or loss of appetite) will trigger admissions to ED. Functional bowel diseases
include irritable bowel syndrome (IBS, a.k.a. spastic colon), functional bloating,
functional constipation, functional diarrhea, and unspecified functional bowel
disorders. Epidemiologic, pathophysiologic and therapeutic studies of functional bowel
diseases, employed the Rome Criteria with universal validity. Patients with malignancy
can experience different types of cancer-related pain at any time during the disease
process, perceived by the organs or systems involved.
