Crohn disease is one common form of inflammatory bowel disease (IBD). Another type of IBD, ulcerative colitis, also causes chronic inflammation of the intestinal lining. Unlike Crohn disease, which can affect any part of the digestive system, ulcerative colitis typically causes inflammation only in the colon. In addition, the two disorders involve different patterns of inflammation.

Crohn's disease is associated with a type of rheumatologic disease known as seronegative spondyloarthropathy. This group of diseases is characterized by inflammation of one or more joints (arthritis) or muscle insertions (enthesitis). The arthritis in Crohn's disease can be divided into two types.

The five types of Crohn's disease and their symptoms are: Ileocolitis: Ileocolitis is the most common type of Crohn's disease. It affects the small intestine, known as the ileum, and the colon. People who have ileocolitis experience considerable weight loss, diarrhea, and cramping or pain in the middle or lower right part of the abdomen.

1 People with this type of Crohn's disease suffer nausea, weight loss, and loss of appetite. In addition, if the narrow segments of bowel are obstructed, they experience vomiting.  Jejunoileitis: This form of the disease affects the jejunum, which is the upper half of the small intestine. It causes areas of inflammation.

Symptoms caused by intestinal stenosis are also common in Crohn's disease. Abdominal pain is often most severe in areas of the bowel with stenoses. Persistent vomiting and nausea may indicate stenosis from small bowel obstruction or disease involving the stomach, pylorus, or duodenum.

Crohn disease is related to chromosomes 5 and 10. Variations of the ATG16L1, IRGM, and NOD2 genes increase the risk of developing Crohn disease. The IL23R gene is associated with Crohn disease. A variety of genetic and environmental factors likely play a role in causing Crohn disease.

The most common disease that mimics the symptoms of Crohn's disease is ulcerative colitis, as both are inflammatory bowel diseases that can affect the colon with similar symptoms. It is important to differentiate these diseases, since the course of the diseases and treatments may be different.

Crohn's disease is caused by a combination of environmental, immune and bacterial factors in genetically susceptible individuals. It results in a chronic inflammatory disorder, in which the body's immune system attacks the gastrointestinal tract possibly directed at microbial antigens.
