There are two types of microscopic colitis: 1) collagenous colitis and 2) lymphocytic colitis. Either collagen or lymphocytes (a type of white blood cell) infiltrate into the layers of the wall of the colon, presumably as a result of inflammation. This is an uncommon illness and may be an autoimmune disease. The diarrhea often is watery, and no blood is present in the stool.
Allergic colitis in infants
In infants younger than 1 year of age, colitis is often due to allergies to cow or soy milk. Allergic colitis may be seen in breastfed babies, where mothers drink cow's milk and pass that protein into their breast milk.
