Signs And Symptoms Intestinal Obstruction
Obstruction of the small bowel causes symptoms shortly after onset abdominal cramps centered around the umbilicus or in the epigastrium, vomiting, and in patients with complete obstruction obstipation. Patients with partial obstruction may develop diarrhea. Severe, steady pain suggests that strangulation has occurred. In the absence of strangulation, the abdomen is not tender. Hyperactive, high-pitched peristalsis with rushes coinciding with cramps is typical. Sometimes, dilated loops of bowel are palpable. With infarction, the abdomen becomes tender and auscultation reveals a silent abdomen or minimal peristalsis. Shock and oliguria are serious signs that indicate either late simple obstruction or strangulation.

- Abdominal Distention
- Abdominal Fullness, Gaseous
- Abdominal pain and cramping
- Breath odor
- Constipation
- Diarrhea
- Vomiting
Volvulus often has an abrupt onset. Pain is continuous, sometimes with superimposed waves of colicky pain
Obstruction of the large bowel usually causes milder symptoms that develop more gradually than those caused by small-bowel obstruction. Increasing constipation leads to obstipation and abdominal distention. Vomiting may occur [usually several hours after onset of other symptoms] but is not common. Lower abdominal cramps unproductive of feces occur. Physical examination typically shows a distended abdomen with loud borborygmi. There is no tenderness, and the rectum is usually empty. A mass corresponding to the site of an obstructing tumor may be palpable. Systemic symptoms are relatively mild, and fluid and electrolyte deficits are uncommon.
