What Is Bowel Obstruction?
A bowel obstruction occurs when stool, fluid, or gas cannot pass through the small or large intestine. A complete blockage can cut off blood flow, leading to serious complications. Prompt diagnosis and treatment are essential to relieve symptoms and prevent further harm.
Common Causes and Risk Factors
Adhesions (scar tissue) from prior abdominal surgery
Hernias pushing intestine through the abdominal wall
Intestinal tumors or cancerous growths
Inflammatory conditions such as Crohn's disease
Certain foods that resist digestion (popcorn, seeds, nuts, raw vegetable chunks)
Older age or a history of multiple abdominal procedures
Signs and Symptoms
Intermittent cramping or belly pain
Abdominal bloating and visible swelling
Nausea and repeated vomiting
Constipation or inability to pass gas
Rapid heart rate, dehydration, and signs of shock in severe cases
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your epigastric pain patterns, onset of vomiting, changes in bowel habits (constipation or inability to pass gas), prior abdominal surgeries and hernia history, and dietary triggers.
Blood Tests
We order a complete blood count to look for infection or anemia, a metabolic panel to assess dehydration and electrolyte imbalances, and inflammatory markers to rule out systemic inflammation.
Imaging Studies
Abdominal X-ray to identify air-fluid levels, dilated loops of bowel, and free air under the diaphragm.
CT scan with oral and IV contrast to pinpoint the obstruction's location, evaluate for strangulation or ischemia, and assess for tumors or strictures.
Contrast Studies (if needed)
A gastrografin or barium follow-through study traces the movement of contrast through the small intestine to confirm partial or intermittent blockages and guide treatment.
Treatment
Our Team offers a full range of care for bowel obstruction.
1. Lifestyle and Diet Modifications
Follow a low-residue diet until swelling eases
Eat small, soft meals and chew thoroughly
Stay hydrated with clear liquids
Avoid hard-to-digest foods that can trigger blockages
2. Medications
IV fluids to correct dehydration
Pain relievers that won't slow your bowels
Anti-nausea drugs for comfort
Stool softeners or laxatives when safe
3. Minimally Invasive or Advanced Procedures
Endoscopic balloon dilation for strictures
Laparoscopic surgery to remove adhesions or hernias

Frequently Asked Questions
Can a bowel obstruction be fatal?
In rare cases, an untreated obstruction can lead to serious complications and even death. Early diagnosis and treatment significantly reduce this risk.
How long does recovery take after surgery?
Most patients go home within 2-5 days after surgery. Full recovery typically takes 4-6 weeks, depending on your overall health and the procedure performed.
What is the small bowel obstruction ICD-10 code?
The ICD-10 code for small bowel obstruction is K56.5, which helps doctors and insurers accurately document and bill for your care.
Can certain foods cause bowel obstruction?
Yes. Foods like popcorn, seeds, nuts, and raw vegetables with tough skins can trigger blockages. Chewing thoroughly and following Dr. Scott's diet plan lowers your risk.
When should I go to the ER?
Seek emergency care if you experience severe abdominal pain, persistent vomiting, or no bowel movements or gas for over 24 hours. These signs may indicate a complete blockage.
Is laparoscopy better than open surgery?
Laparoscopy uses small incisions, which usually means less pain, lower infection risk, and faster healing. Dr. Scott will recommend the best approach for your condition.
Do I need a CT scan?
A CT scan provides detailed images to locate the blockage and guide your treatment plan. Dr. Scott uses imaging when it improves safety and outcomes.
