Bowel obstruction occurs when food, fluids, or gas cannot move through the small or large intestines (ICD-10: K56.6). This blockage leads to abdominal pain, swelling, nausea, and vomiting. If not treated promptly, it can result in tissue death or serious infection.
He reviews your medical history, prior abdominal surgeries, risk factors, and symptom timeline, then performs a gentle abdominal examination.
We check for signs of infection, electrolyte imbalances, dehydration, and overall metabolic status.
A small bowel follow-through or enteroclysis tracks contrast movement to map out the obstruction and aid treatment planning.
Occasionally, endoscopic evaluation or additional specialized imaging may be ordered to clarify complex cases.
