Patient presents with acute abdominal pain consistent with possible ischemic bowel.  Onset of symptoms was described as sudden and severe, localized to the (periumbilical, right lower quadrant, left lower quadrant, or generalized) region.  Patient reports (nausea, vomiting, diarrhea, bloody stools, constipation) and denies (nausea, vomiting, diarrhea, bloody stools, constipation).  Physical examination reveals (abdominal tenderness, rebound tenderness, guarding, distension).  Bowel sounds are (present, absent, hyperactive, hypoactive).  Differential diagnosis includes acute mesenteric ischemia, chronic mesenteric ischemia, ischemic colitis, small bowel obstruction, and other acute abdominal emergencies.  Initial laboratory workup includes complete blood count (CBC), comprehensive metabolic panel (CMP), lactate, and arterial blood gas (ABG).  Imaging studies such as computed tomography angiography (CTA) of the abdomen and pelvis are ordered to evaluate for vascular compromise and assess bowel viability.  Patient is currently being managed with intravenous fluids, pain control, and bowel rest.  Further management will be determined based on imaging results and clinical progression, potentially including surgical intervention if indicated.  Diagnosis:  Rule out ischemic bowel.  Plan:  Monitor for signs of peritonitis, sepsis, and bowel infarction.  Continue supportive care and reassess frequently.
