About this condition
Bowel obstruction is a partial or complete failure of intestinal contents to move normally. It can threaten blood flow and fluid balance and must be assessed urgently in a hospital.
What matters most
A physical blockage may be caused by adhesions, a hernia, a mass or twisting of bowel. Loss of bowel movement can also occur from impaired intestinal motility. The cause cannot be determined safely at home.
Symptoms and reasons to seek help
Cramping or constant abdominal pain, increasing distension, nausea and repeated vomiting are common warnings. Passing some gas or stool does not completely rule out a partial obstruction.
How it differs from similar conditions
Severe constipation, inflammation and other abdominal emergencies can overlap with these symptoms. A mechanical obstruction needs a different approach from simple constipation or a temporary change in stool pattern.
Assessment and investigations
Emergency clinicians assess vital signs, hydration and abdominal findings, then select laboratory tests and imaging. They look for compromised bowel blood supply, peritonitis or other complications.
Care options and limitations
Treatment depends on the identified cause and is managed in hospital; some patients require urgent surgery. Do not take laxatives, force food or try home remedies while obstruction is suspected.
When emergency help is needed
Possible bowel obstruction warrants immediate emergency assessment, not a routine appointment. Call 103 or 112 for severe pain, repeated vomiting, marked swelling or inability to pass gas, especially when the person is deteriorating.

Frequently asked questions
Can bowel obstruction happen without complete constipation?
Yes. Some stool or gas can still pass during partial obstruction, so other warning signs remain important.
Can I use a laxative if my abdomen is swollen and painful?
No. Suspected obstruction needs urgent professional assessment, and laxatives may be unsafe.
Does every obstruction need an operation?
Not always, but only a hospital team can decide on safe treatment after assessing the cause and severity.
