Bowel Wall Thickening
Bowel wall thickening is a finding on imaging where part of the small or large intestine looks thicker than expected.
When to get help quickly: Severe abdominal pain, vomiting, fever, blood in the stool, or signs of obstruction or peritonitis need urgent review because the underlying cause may need surgery or hospital care.
Common symptoms
It does not itself cause symptoms, but the underlying cause may produce abdominal pain, diarrhoea, blood in the stool, weight loss, or fever.
When imaging helps
Imaging shows where the thickening is, how long the affected segment is, and whether the pattern suggests inflammation, infection, ischaemia, or a tumour.
What radiology does
CT and MR enterography assess the bowel wall; ultrasound can help in younger patients and pregnancy; endoscopy and biopsy may follow if needed.
What usually happens next
Treatment depends entirely on the cause — antibiotics for infection, medications for inflammatory bowel disease, surgery for ischaemia or tumour.
