Symptoms include stomach pain, diarrhea, and bleeding. Crohn's disease and ulcerative colitis are the 2 main types of IBD. Researchers want to conduct a natural history study to learn more about whether genetic factors can cause IBD; how immune cells contribute to IBD; and how diet, drugs, and disease affect those cells.\n\nObjective:\n\nTo better understand IBD over time.\n\nEligibility:\n\nAdults aged 18 to 85 years with Crohn's disease, ulcerative colitis, or another IBD. Their healthy relatives are also needed.\n\nDesign:\n\nAffected participants will have clinic visits every 6 months for 3 years.\n\nOnce a year, they will have these procedures:\n\nA physical exam with blood and stool samples.\n\nUltrasound of the abdomen. A wand will be rolled over the skin. It uses sound waves to capture images of the intestines.\n\nMagnetic resonance imaging (MRI) scan. They will lie on a table that slides into a tube. Magnetic fields will capture images of the intestines.\n\nColonoscopy. A long, flexible tube with a video camera will be inserted into the rectum to view the entire colon. Up to 12 tissue samples may be taken.\n\nUpper endoscopy, for those with Crohn's disease. A long, thin tube with a camera will be inserted through the mouth and into the first part of the small intestine. Up to 12 small tissue samples may be taken.\n\nQuestionnaires. Participants will answer questions about their disease and their diet.\n\nMidyear visits will include a physical exam, blood and stool collection, ultrasound, and questionnaires\n\nHealthy relatives will have 1 blood draw for genetic tests.",[60,61,62],"Inflammatory Bowel Disease","Crohn's Disease","Ulcerative Colitis",[64,65,66],"Immune System","Inflammation","gastroenterology","NOT_YET_RECRUITING","2026-07-01",{"date":70,"type":71},"2026-07-02","ACTUAL",{"date":73,"type":56},"2026-07-07",{"date":75,"type":56},"2036-06-01",{"name":18,"class":6},1]
