Vomiting, diarrhea, and hyperactive bowel sounds may be present. When evaluating a patient with a history of cocaine use and a complaint of abdominal pain, consider mesenteric ischemia in the differential diagnosis. Patients with abdominal pain must also be evaluated for renal infarction.

The vascular supply to the intestine has many alpha-adrenergic receptors, and their stimulation may cause mesenteric ischemia. The clinical presentation of mesenteric ischemia includes abdominal pain and possibly tenderness, nausea, vomiting, and bloody diarrhea. Muscarinic receptor blockade results from high concentrations of cocaine, with anticholinergic effects on gastric motility that predisposes the person to ulceration from prolonged exposure to acid.
