IBD tool is a project born from the collaboration of the Mauriziano Hospital in Turin and the Links Foundation, with the aim of developing a web application to support the monitoring of patients affected by IBD(inflammatory bowel disease). IBDs are chronic diseases that affect the gastrointestinal tract causing, among other symptoms, abdominal pain, diarrhea, rectal bleeding and weight loss. The cause of IBDs is uncertain, and the only treatments that can be applied focus on trying to reduce the burden of the disease. People affected by IBD undergo periods of remission of the illness, with less symptoms detected, and periods of relapse, when the disease's symptoms are heavier.
