Causes of Microscopic Colitis
What Causes Microscopic Colitis?
Scientists believe abnormal immune system responses cause microscopic colitis. When this happens, your body’s immune system attacks your cells and organs. Examples of other autoimmune conditions include celiac disease and rheumatoid arthritis.
Other possible causes for microscopic colitis include:
- Bacteria that produce toxins and irritate the lining of your colon
- Food sensitivity, which can cause symptoms when you eat trigger foods, such as dairy and gluten
- Genetic factors, which can be passed down from one generation to another
- Medications, including aspirin and ibuprofen, which can irritate the lining of your colon
- Viruses that trigger inflammation
