Types of Crohn's Disease and Associated Symptoms

If you are diagnosed with Crohn’s Disease, it’s important to know and understand which part of your GI tract is affected and how this may affect the symptoms and complications you experience.

The following are five types of Crohn's disease, together with their presenting symptoms:

Ileocolitis

The most common form of Crohn's, ileocolitis affects the end of the small intestine (the ileum) and the large intestine (the colon). Symptoms include diarrhea and cramping or pain in the right lower part or middle of the abdomen. This type is often accompanied by significant weight loss.

Ileitis

This type affects only the ileum. Symptoms are the same as ileocolitis. In severe cases, complications may include fistulas or inflammatory abscess in right lower quadrant of abdomen.

Gastroduodenal Crohn's disease

This type affects the stomach and the beginning of the small intestine(the duodenum). Symptoms include loss of appetite, weight loss, nausea, and vomiting.

Jejunoileitis

This type is characterized by patchy areas of inflammation in the upper half of the small intestine (the jejunum). Symptoms include mild to intense abdominal pain and cramps following meals, as well as diarrhea. In severe cases or after prolonged periods, fistulas may form.

Crohn's (granulomatous) colitis

This type affects the colon only. Symptoms include diarrhea, rectal bleeding, and disease around the anus (abscess, fistulas, ulcers). Skin lesions and joint pains are more common in this form of Crohn's than in others
