Gastroenteritis or infectious diarrhea is a medical condition from inflammation (-itis) of the gastrointestinal tract that involves both the stomach (gastro -) and the small intestine (entero -).It causes some combination of diarrhea, vomiting, and abdominal pain and cramping.iruses (particularly rotavirus) and the bacteria Escherichia coli and Campylobacter species are the primary causes of gastroenteritis. There are, however, many other infectious agents that can cause this syndrome. Non-infectious causes are seen on occasion, but they are less likely than a viral or bacterial cause.
Inflammatory bowel disease (IBD) is a general name for diseases that cause inflammation in the intestines. Collagenous colitis is a type of bowel inflammation that affects the colon (large intestine).Collagenous colitis is not related to Crohn's disease or ulcerative colitis, which are more severe forms of inflammatory bowel disease.Also, collagenous colitis does not increase the risk of colon cancer.ollagenous colitis and another type of colitis, called lymphocytic colitis, are referred to as microscopic colitis because colonoscopy usually shows no signs of inflammation on the surface of the colon. Instead, tissue samples from the colon must be examined under a microscope to make the diagnosis.
