Crohn's disease - Inflammatory bowel disease

Low urgency
--

It is a chronic inflammation of the digestive tract in any area of its entire length. 

Its cause is uncertain but is attributed to a certain genetic predisposition that activates the immune response. 

Common symptoms include abdominal pain, diarrhea, fever, weight loss and swelling of the abdomen. 

It is diagnosed by detailed clinical history, physical examination and complementary tests such as laboratory tests, radiological examinations and colonoscopy. 

Treatment is based on symptom control with dietary measures and medications. More severe cases may require surgical intervention.
