Types of Crohn’s Disease
There are 5 types of Crohn's Disease
based on the gastrointestinal area affected. The lesions
due to Crohn’s disease may appear in any part of the
alimentary canal from the mouth to the anus.
Gastroduodenal Crohn’s Disease:
The type of Crohn’s Disease which affects the
stomach and duodenum (the starting portion of the small
intestine) is called gastroduodenal Crohn’s disease.
Often, a correct diagnosis of GCD is not made until all
options to treat an ulcer fail, or GCD is identified
farther down the gastrointestinal tract. Symptoms of GCD
consist of loss of weight and appetite, nausea, pain in
the upper middle part of the abdomen and vomiting.
Vomiting indicates the obstruction of narrowed
segments of the bowel (3).
Jejunoileitis:
Crohn’s disease affecting the longest
portion of small intestine (jejunum), between
duodenum and ileum, is called jejunoileitis. Mild
to intense abdominal pain and cramps after meals,
diarrhea, malnutrition caused by malabsorption of
nutrients and Fistulas are some of the symptoms
of this type. The diseased portion of small
intestine may be linked to another area of the
intestine or another organ, such as the bladder
and it is important to note that the risk of
developing infections outside the digestive tract
is high due to fistulas. Jejunoileitis may
produce patchy areas of inflammation in the
jejunum (3).

Ileitis:
Crohn’s disease affecting the lowest or last part of
the small intestine (i.e., ileum) is called ileitis. The
symptoms of ileitis Crohn’s include: cramping or
pain in the right lower quadrant and periumbilical area
after meals, malabsorption of vitamin B12 leading to
tingling of fingers or toes, and folate deficiency
hindering the development of red blood cells making the
patient anemic.Complications may lead to fistulas or
inflammatory abscess in right lower quadrant of abdomen
(3).
Illeocolitis:
Illeocolitis is one of the more common types of
Crohn’s disease and affects the lowest part of small
intestine (ileum) and the large intestine (colon).
Generally, the affected portion of the colon is
continuous with the diseased portion of ileum involving
the ileocecal valve between the ileum and the colon. In
some cases, discontinuous inflammation in the colon with
ileum may be observed. Symptoms are essentially the same
as in ileitis with the addition of weight loss.
Crohn's Colitis (Granulomatous Colitis):
Crohn’s disease affecting the colon is called
Crohn’s Colitis or Granulomatous Colitis. It differs
from ulcerative colitis in two ways:
- Ulcerative colitis is always continuous whereas
in Crohn’s colitis, areas of healthy tissue
are interspersed between areas of diseased
tissue.
- Ulcerative colitis always affects the rectum and
areas of colon beyond rectum, whereas
Crohn’s colitis appears only in the colon.
Diarrhea, rectal bleeding and disease around the anus
(such as abscess, fistulas and ulcers) are the symptoms
of this type. Skin lesions and joint pains are common in
this type (CCFA).
