1 Viruses that trigger inflammation.  Autoimmune disease associated with microscopic colitis, such as rheumatoid arthritis or celiac disease. Autoimmune disease occurs when your body's immune system attacks healthy tissues.
In these diseases, the inflammation is caused when the colon wall becomes engorged with either collagen or lymphocytes. Watery, non-bloody diarrhea is the most common symptom. This is an uncommon illness that is seen more frequently in older women. The cause is unknown but an autoimmune potential may exist. 5. Chemical Colitis. If chemicals are instilled into the colon, inflammation and damage can occur. One of the complications of an enema is inflammation of the mucosal lining of the colon caused by harsh chemicals. 6. Medication-associated colitis. Colitis can be caused by some over-the-counter and prescription medications such as NSAIDs (nonsteroidal anti-inflammatory drugs), mycophenolate, ipilimumab, and retinoic acid.
