Crohn's disease is a chronic inflammatory bowel disease (IBD) that affects the lining of the digestive tract. It can cause a wide range of symptoms, including abdominal pain, diarrhea, weight loss, and malnutrition. Crohn's disease can affect people of all ages, but it is most commonly diagnosed in people between the ages of 15 and 35.

In the United States, approximately 780,000 people have Crohn's disease. The disease is more common in whites than in blacks or Hispanics. Additionally, men and women are equally affected by Crohn's disease.

There is no cure for Crohn's disease, but there are a variety of treatments that can help to manage the symptoms and prevent complications. Treatment options may include medications, dietary changes, and surgery. With proper treatment, most people with Crohn's disease can live full and productive lives.
