Enterocolitis and colitis are not the same. First, conceptually, enteritis includes inflammation of the small intestine and inflammation of the large intestine, while colitis includes only inflammation occurring in the colon. Secondly, inflammation can include both infectious aka bacterial inflammation and mechanical inflammation as well as autoimmune systemic diseases. What is commonly referred to as enteritis is acute gastroenteritis, which occurs in the summer and fall months and causes damage to the absorptive function of the small intestine after eating unclean food, resulting in increased fecal discharge from the colon, causing abdominal pain, bloating, and even diarrhea. There are three main clinical categories of colitis: the first, commonly referred to as acute gastroenteritis. The second major category, mainly fecal colitis, is common in the elderly because of damage to the colonic mucosa caused by dry and hard stools, resulting in mechanical inflammation, which can be complicated by bacterial infection and cause bacterial colitis. The third major category, autoimmune products, such as ulcerative colitis. So, enteritis and colitis are not the same.
