Colonic Pseudoobstruction
Colonic pseudoobstruction, a condition where the colon stops proper movement without a physical blockage, can cause severe bloating, pain, and digestive distress. In Houston, Dr. Nghia Nguyen at GastroDoxs offers expert diagnosis and personalized, minimally invasive treatments for lasting relief.
Dr. Nghia Nguyen, DO, is a board-certified gastroenterologist providing advanced digestive care in the Greater Houston area. He earned his medical degree from the Texas College of Osteopathic Medicine and completed both his Internal Medicine residency and Gastroenterology fellowship at the University of Texas at Rio Grande Valley. Dr. Nguyen specializes in treating conditions such as acid reflux, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and liver disorders.
What Is Colonic Pseudoobstruction?
Colonic pseudoobstruction occurs when the colon's muscles fail to move stool forward, creating the appearance of an obstruction on imaging without any physical blockage. This motility disorder can lead to pain, bloating and changes in bowel habits.
Common Causes and Risk Factors
Recent abdominal or spinal surgery
Medications that slow intestinal motility (e.g., opioids, anticholinergics)
Chronic conditions such as diabetes or Parkinson's disease
Electrolyte imbalances (low potassium or magnesium)
Advanced age or limited mobility
Signs and Symptoms
Severe abdominal bloating or distension
Cramping or abdominal pain
Nausea and occasional vomiting
Reduced frequency of bowel movements or constipation
Feeling full after small meals
How Dr. Nghia Nguyen Diagnoses Colonic Pseudoobstruction?
Dr. Nguyen uses a step-by-step approach:
Medical History and Physical Exam
He reviews your recent surgeries (especially abdominal or spinal), current medications (like opioids), long-term conditions (diabetes, Parkinson's), and performs an abdominal exam for distention, tenderness, and bowel sounds.
Imaging Studies
Abdominal X-ray to look for colonic dilation and rule out a mechanical blockage.
CT scan of the abdomen and pelvis for detailed evaluation of the colon and surrounding organs.
Blood Tests
He checks electrolytes (potassium, magnesium) to identify imbalances and orders a complete blood count to screen for infection or inflammation.
Colonic Motility Testing
Transit studies or manometry may be used to measure how well your colon muscles contract and move stool along.
Advanced Evaluation (if needed)
In select cases, endoscopic decompression or specialized motility assessments help confirm the diagnosis and refine treatment planning.

Frequently Asked Questions
What causes colonic pseudoobstruction?
It can occur after abdominal or spinal surgery, with certain medications (like opioids), or in people with chronic conditions such as diabetes or Parkinson's disease.
How soon should I get help?
If you have severe abdominal pain or noticeable swelling, contact a doctor within 24 hours to prevent complications.
Can this become serious?
Yes. Without prompt care, colonic pseudoobstruction can lead to bowel tears, infection, or other life-threatening issues. Early treatment reduces these risks.
What tests are needed?
You may need abdominal X-rays or CT scans, blood work to check electrolytes and infection, and motility studies to assess colon function.
Can food alone fix it?
A healthy diet and lifestyle changes may help mild cases, but many patients also require medications or a minimally invasive procedure.
Does GastroDoxs accept insurance?
Yes. Most plans are accepted. Please call our Houston office to verify your coverage before your visit.
Will I need surgery?
Most patients respond well to non-surgical treatments such as diet, medications, or endoscopic procedures, so surgery is rarely needed.
