Inflammatory bowel disease (IBD) generally refers to Crohn’s disease and Ulcerative colitis which both cause inflammation in parts of the gastrointestinal tract, leading to symptoms such as abdominal pain, diarrhoea, rectal bleeding and weight loss. They can also be associated with eye, joint and skin problems in some people.  Symptoms often vary over time. There are lots of treatments available to reduce the gut inflammation and you can find lots of information on these at https://www.crohnsandcolitis.org.uk/
