Intestinal Obstruction
Emergency
Intestinal obstruction occurs when food, fluid or digestive contents cannot move normally through the intestine. The blockage may be partial or complete and can occur in the small or large intestine. It may cause abdominal pain or cramping, swelling, vomiting, constipation and inability to pass gas. A complete obstruction can become a medical emergency because it may damage the intestine.

Overview
Intestinal obstruction occurs when food, fluid or digestive contents cannot move normally through the intestine. The blockage may be partial or complete and can occur in the small or large intestine. It may cause abdominal pain or cramping, swelling, vomiting, constipation and inability to pass gas. A complete obstruction can become a medical emergency because it may damage the intestine.
Symptoms 3
Blood In Vomit
Constipation
Lower Abdominal Pain
Causes 1
Common causes include scar tissue called adhesions, hernias, tumors, inflammatory bowel disease and twisting or telescoping of the intestine. In children, congenital abnormalities and other developmental problems may cause obstruction. Certain conditions can slow intestinal movement without a physical blockage. The cause depends on the location and type of obstruction and may require imaging or surgery to determine.
Inflammation
Risk Factors
Risk factors include previous abdominal or pelvic surgery, hernias, abdominal or intestinal tumors, inflammatory bowel disease and conditions that can cause abnormal intestinal movement. Older adults may have a higher risk of some forms of obstruction. A history of previous intestinal obstruction also increases the chance of recurrence. Risk varies according to the underlying cause.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on symptoms, physical examination and imaging. Healthcare professionals may listen for changes in bowel sounds and examine the abdomen for swelling or tenderness. Abdominal X-rays, CT scans or other imaging tests can help identify the location and cause of a blockage. Blood tests may be used to assess dehydration, infection or other complications.
Prevention
Key Prevention Tips
Not all intestinal obstructions can be prevented
Reducing the risk involves managing conditions that can cause blockage, following medical advice after abdominal surgery and seeking treatment for hernias or other structural problems when recommended
People with inflammatory bowel disease should follow their treatment plan
Prompt medical attention for severe abdominal pain, repeated vomiting or inability to pass stool or gas can help prevent complications
