Diagnosing Crohn's Disease - How To Get A Diagnosis
Diagnosing Crohn's Disease is often a difficult process. Because
it mimics other diseases, Crohn's may appear to be a myriad of
other ailments. Likewise, the symptoms experienced vary from
patient to patient, so there are no set guidelines to follow or
sings that intrinsically point to Crohn's.
There is not a single to test to establish the existence of
Crohn's Disease definitively. However, there are several
procedures that are done to ascertain if Crohn's, as well as
other digestive tract disorders, are at fault for symptoms being
experienced. One such area of examination is stool samples. It
must first be determined that the inflammation in the bowels is
not the result of an infection. With Crohn's, inflammation
occurs as though there is an infection, but none exists.
Therefore, obtaining this information may rule out many possible
culprits.
Other tests that may be done are blood tests, a colonoscopy, a
flexible sigmoidoscopy, a barium enema, small bowel x-rays, a
capsule endoscopy, or a CT scan.
Blood tests may be used to check for signs of infection as well
as anemia. As stated above, the existence of an infection would
rule out Crohn's disease. However, if anemia is present, Crohn's
may be more likely. One of the possible symptoms of Crohn's
Disease is rectal and intestinal bleeding. Due to this excessive
blood loss, many people will become anemic. Therefore, the
existence or nonexistence of anemia is another step in
diagnosing digestive disorders.
Another option is a colonoscopy. This procedure is done with the
insertion of a lighted tube with an attached camera through the
rectum into the colon to check for signs of Crohn's Disease.
However, there are risks to this procedure, including
perforating the colon wall and bleeding as a result. Another
consideration is that Crohn's Disease may only occur in the
small intestine and not the colon; therefore this procedure
would be ineffective in that case.
Similar to a colonoscopy is a flexible sigmoidoscopy, which is
the long tube without the camera. The doctor would check for
similar things as in a colonoscopy and the same side effects
exist. However, this procedure can only examine the last two
feet of your colon and would be ineffective on diagnosing
problems in higher regions.
A barium enema may be used to provide a silhouette o the
digestive tract through an x-ray after barium is inserted in
enema form. This, like the other tests that are used, is not as
effective as a colonoscopy but may provide valuable clues.
