Gastrointestinal bleeding |
| Appendicitis is an inflammation of the appendix, a small, fingerlike tube that hangs from the lower right side of the large intestine. Appendicitis may occur after a viral infection in the digestive tract or when the tube connecting the large intestine and appendix is blocked or trapped by stool. |
|
Gastointestinal (GI) bleeding describes any blood loss that occurs through the digestive tract. GI bleeding can emanate from any site along the way. Doctors often divide digestive tract bleeding into upper GI tract bleeding, lower GI bleeding or occult GI bleeding. Those with heavy bleeding may need blood transfusions. |

Ileus |
| Rectal bleeding is a type of lower GI bleeding. GI stands for gastro-intestinal. The lower GI includes the intestines (bowel) and rectum. Rectal bleeding is frequently noticed as black, tarry stools, maroon stools, bright red blood on or in the stool, blood on the toilet tissue, or blood staining the toilet bowl water red. |
|
Ileus is a partial or complete non-mechanical blockage of the small and/or large intestine. Ileus is a functional rather than mechanical obstruction of the bowel. It is a lack of propulsive peristalsis (wave-like movement) of the bowel. Ileus is most often associated with an infection of the peritoneum. |

| Peritonitis |
|
|
| Peritonitis is infection (or inflammation) of the peritoneum, which is a two-layered membrane covering both the surfaces of the organs that lie in the abdominal cavity and the inner surface of the abdominal cavity itself. Primary peritonitis usually occurs in people who have an accumulation of fluid in their abdomens. |
