Collagenous colitis is a microscopic type of colitis, which is typified by watery and persistent diarrhea. On microscopic observation, a layer of collagen (a structural protein) is observed as getting thick immediately below the colon in the lining. Although the bowel movements are frequent and urgent, colonoscopy or endoscopy shows a normal lumen. The symptoms usually recover fast with appropriate treatment and diagnosis.
He also examines bowel, medication history (NSAIDs, PPIs, antidepressants), autoimmune history and performs physical examination to exclude the presence of abdominal tenderness or distension in your body.
Stool samples are analyzed with a view of excluding infections (bacteria, parasites), Clostridioides difficile, and are used to determine the level of inflammatory indicators such as fecal calprotectin.
Blood tests of Celiac disease or thyroid functioning are ordered occasionally, or imaging (CT or MRI) to rule out other gastrointestinal diseases.
