Microscopic Colitis is an Inflammatory Bowel Disease that affects the large bowel (colon and rectum). There are two main forms of Microscopic Colitis – Lymphocytic Colitis and Collagenous Colitis. These are very similar conditions and are commonly referred to under the single name ‘Microscopic Colitis’. 


Microscopic Colitis is an Inflammatory Bowel Disease (IBD) that affects the large bowel - the colon and rectum. It isn’t always as well-recognised as Crohn’s Disease or Ulcerative Colitis, other forms of IBD. 

It can take to time to get a diagnosis of Microscopic Colitis. And dealing with watery poo, tummy cramps, and rushing to the toilet can all be hard to manage. But you’re not alone; we’re here to support you. Many people respond well to treatment and often symptoms go away when you find what’s right for you.
