Ischemia

Definition

Ischemia is a condition where there is a reduction in blood flow to tissues, causing a shortage of oxygen and nutrients needed for cellular metabolism. It can lead to tissue damage and is often associated with various digestive conditions.

5 Must Know Facts For Your Next Test

1. Ischemia in the digestive system can result from blockages in the arteries supplying blood to the intestines.
2. Common symptoms of intestinal ischemia include abdominal pain, nausea, vomiting, and bloody stools.
3. Chronic mesenteric ischemia can occur due to atherosclerosis, leading to long-term digestive issues and malnutrition.
4. Acute mesenteric ischemia requires immediate medical intervention to restore blood flow and prevent tissue death.
5. Dietary management for patients with ischemic conditions may involve low-fat diets to reduce arterial plaque buildup.
