<unk>  (a.k.a. bowelgina) is postprandial abdominal pain that occurs in individuals with insufficient blood flow to meet visceral demands. The term<unk>  is used in reference to<unk>  pectoris, a similar symptom due to obstruction of the coronary artery. The American Heritage Stedman's Medical Dictionary defines<unk>  (bowelgina) as "Intermittent abdominal pain, frequently occurring at a fixed time after eating, caused by inadequacy of the mesenteric circulation. Also called  intestinal<unk> ; bowelgina." 
Mesenteric ischemia is a type of peripheral vascular disease that occurs when the blood supply can not meet the metabolic demands of visceral organs. Acute mesenteric ischemia is a surgical emergency that presents severe abdominal pain which is described as "pain out of proportion to physical examination." However, chronic mesenteric ischemia (CMI) usually presents with vague abdominal pain that may be difficult to differentiate from other, more common causes of abdominal pain
