THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Patients with small-volume diarrhea often have disease in their left colon or rectum, often an inflammatory process. But probably the most common cause for intermittent small-volume chronic diarrhea is the irritable bowel syndrome, which is always a diagnosis of exclusion.

Detailed explanation-2: -Postprandial diarrhea is diarrhea that occurs after eating. It can happen unexpectedly and cause discomfort or pain until a bowel movement occurs. Possible causes include an infection, antibiotic use, and gastrointestinal conditions, such as inflammatory bowel disease.

Detailed explanation-3: -Diarrhea occurs when the large intestine is prevented, for any number of reasons, from sufficiently absorbing the water or other digestive fluids from fecal matter, resulting in a liquid, or “loose", bowel movement.
