Abdominal angina (a.k.a. bowelgina) is postprandial abdominal pain that occurs in individuals with insufficient blood flow to meet visceral demands. The term angina is used in reference to angina pectoris, a similar symptom due to obstruction of the coronary artery.

[edit] Pathophysiology
The pathophysiology is similar to that seen in angina pectoris and intermittent claudication. The most common cause of bowelgina is atherosclerotic vascular disease, where the occlusive process commonly involves the ostia and the proximal few centimeters of the mesenteric vessels.
[edit] Frequency
- Internationally: Extremely rare. True incidence is unknown
- Race: No data available
- Sex: Females outnumber males by approximately 3 to 1
- Age: Mean age of affected individuals is slightly older than 60 years
[edit] Clinical
- Hallmark of condition: Disabling midepigastric or central abdominal pain within 10-15 minutes after eating.
- Physical examination: The abdomen typically is scaphoid and soft, even during an episode of pain. Patients present with stigmata of weight loss and signs of peripheral vascular disease, particularly aortoiliac occlusive disease, may be present.
- Causes: Smoking is an associated risk factor. In most series, approximately 75-80% of patients smoke.
