Crohn's Disease Facts

For people with Crohn's disease, symptoms like abdominal pain, cramping, and urgency to use the restroom get in the way of everyday life. Though the condition affects as many as 780,000 people in the U.S., not everyone knows about or understands the severity of the condition.

Whether you're living with Crohn's disease or know someone who does, these statistics on risk factors and how symptoms impact quality of life can deepen your understanding of the disease.
