Intestinal ischemia is a medical condition in which injury to the large or small intestine occurs due to not enough blood supply. [2] It can come on suddenly, known as acute intestinal ischemia, or gradually, known as chronic intestinal ischemia. [ 1 ]
Mesenteric ischemia (also called a bowel infarction, or lack of blood flow to small intestine) Diarrhea or constipation. Nausea or vomiting. Gas. Rectal bleeding. Low blood pressure. Severe ...
Ischemia (loss of blood flow) to the affected portion of intestine. Depending on the location of the volvulus, symptoms may vary. For example, in patients with cecal volvulus, the predominant symptoms may be those of small bowel obstruction (nausea, vomiting and lack of stool or flatus), because the obstructing point is close to the ileocecal ...
The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion. The small intestine is about 5.5 metres (18 feet) long and folds ...
A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus.

In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
Plaque can limit the supply of blood and oxygen to your heart tissue. Many people with early coronary artery disease don’t have any symptoms. If your heart doesn’t get enough oxygen, you might ...
Ischemia or ischaemia is a restriction in blood supply to any tissue, muscle group, or organ of the body, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). [ 3 ] [ 4 ] Ischemia is generally caused by problems with blood vessels , with resultant damage to or dysfunction of tissue i.e. hypoxia and ...
