According to researchers, psychological and infectious factors are also major players which influence IBD development.
Since IBD shares symptoms with numerous other maladies, diagnosing IBD is based on a combination of exams such as blood and tissue tests, endoscopic, stool examination, and X-rays. Examination of stool might eliminate the possibility of bacterial or viral causes of diarrhea. A common blood exam, such as blood count could be used to examine the level of the white and red blood cell count. High WBC is indicative of inflammation and low RBC may suggest that the person might have been bleeding (perhaps from the damaged of the intestinal wall)) and hemoglobin level may fall (anemia). As mentioned in the previous post, two illness that are associated with IBD are Crohn's disease (more to come on this in later post) and ulcerative colitis. Endoscopic is used to determine if the patient has either of these conditions and this also reveal how much affected is the bowel. There are numerous endoscopies exams that could be used (see figure below).
X-rays exams are useful such that they provide valuable information that endoscopy cannot. For example, Colonoscopy can visualize only the stomach, the upper small intestine. Endoscopy cannot imaged most of the small intestine.
The preferable exam of choice will be based on affordability or whatever the doc might think is necessary. In other words, there is no one best diagnostic tool. All those mentioned above are valuable options.
