    Description Crohn's Disease (CD) causes inflammation of the digestive tract that may lead to abdominal pain, severe diarrhea, fatigue, weight loss, and malnutrition. When that inflammation is only in the large intestine (including the colon) the disease is called ulcerative colitis (UC).

    Both UC and CD are caused by an autoimmune response that reflects the involvement of the innate and adaptive immune systems. The disease mechanism is complex, but appears to start when a normal immune response to a bacterial infection does not stop properly after the infection is fought off. The resulting inflammation leads to the symptoms of both UC and CD.

    Evidence of autoimmunity: T cells

As of July 2024, there are 451,000 sets of electronic health records and over 560,000 participants who have completed initial survey questions. This dataset, however, may not be representative of the US population. A snapshot of the data can be found here. To protect participant anonymity, results derived from fewer than 20 participants are not graphed.

As of July 2024, there are 451,000 sets of electronic health records collected from participants. In the United States, because electronic health records use billing codes for diagnoses, some conditions may not be perfectly captured by these data, especially if the condition is rare.
