16 May 2017 --- A University of Manchester test on the mucus lining of the intestine, performed in mice, has found changes in bacteria that could lead to inflammatory bowel disease 12 weeks earlier than previously possible through looking at stool samples, leading to the possibility of earlier diagnosis and better management of the disease in humans. Inflammatory bowel diseases such as Crohn’s Disease and ulcerative colitis are chronic conditions that can cause severe pain, weight loss and diarrhea.
