Name and describe one disease of your choice that is associated with the digestive, urinary, or nervous body systems. explain the symptom(s) typically present and the lab tests that may be recommended.

The Crohn’s disease can be an example of a disease associated with the digestive system.

The Crohn’s disease is a chronic inflammation of the gastrointestinal tract. Although it can be developed in any part of the gastrointestinal tract it is mostly aggressive ate the end of the small intestine to the passage to large intestine. It affects equally men and women and it starts usually between the ages of 15-35 years of age. It may appear because of genetic factors, environment, and simply an overactive inflammatory system. 
It usually presents abdominal pain, rectal bleeding, frequent diarrhea, loss of appetite, weight-loss, and fatigue.
It is usually tested by blood tests to identify eventual deficiencies of vitamins or minerals, and other indicators of anemia or inflammation. Also fecal blood tests to identify if the problem could be a result of some kind of infection rather then Crohn's disease. Other tests may include X-rays, CT scans,or MRIs, leukocyte scintigraphy, endoscopy, and colonoscopy.
