Chronic Intestinal Pseudo-Obstruction (CIPO): Symptoms & UK Management

Intestinal pseudo-obstruction is a rare but serious condition where the intestines lose their ability to push food, stool, and air through the digestive tract. While the symptoms mirror those of a physical bowel blockage (mechanical obstruction), such as a tumour or adhesion, no actual physical barrier exists. Instead, the problem lies within the muscles or nerves that control gut motility.

In the UK, this condition is often classified as either acute (Ogilvie's syndrome) or chronic intestinal pseudo-obstruction (CIPO). CIPO is a long-term condition that can significantly affect a patient's quality of life, requiring careful monitoring by gastroenterology specialists and primary care providers.

The symptoms of pseudo-obstruction can vary in intensity, often flaring up before periods of relative stability. Patients typically report:

• Abdominal Distension: Significant bloating that causes the stomach to feel hard and look visibly swollen.
• Chronic Pain: Crunched or colicky pain in the abdomen.
• Nausea and Vomiting: Particularly after eating, as the stomach fails to empty efficiently.
• Constipation or Diarrhoea: Altered bowel habits are common, sometimes involving bacterial overgrowth (SIBO) leading to loose stools.
• Weight Loss: Difficulty absorbing nutrients or fear of eating due to pain often leads to unintentional weight loss.

Medical professionals categorise pseudo-obstruction based on its origin. Primary CIPO occurs when the defect is inherent to the gut wall, such as hollow visceral myopathy (muscle issues) or neuropathy (nerve issues). This is often genetic or idiopathic.

Secondary pseudo-obstruction is caused by an underlying systemic disease. NICE guidelines and NHS pathways often investigate for triggers such as:

• Diabetes mellitus (diabetic gastroparesis/enteropathy).
• Scleroderma or other connective tissue disorders.
• Neurological conditions like Parkinson’s disease.
• Certain medications, particularly long-term opioid use or anticholinergics.
• Electrolyte imbalances, such as low potassium or high calcium.

Diagnosis is often a process of exclusion. Because the symptoms are identical to an emergency bowel obstruction, the first step is usually an X-ray or CT scan. In pseudo-obstruction, these images will show dilated loops of bowel filled with air, but no physical mass or twist.

Once a mechanical blockage is ruled out, specialists may use manometry to measure the pressure of intestinal contractions or gastric emptying studies. Blood tests are also performed to check for nutritional deficiencies (such as Vitamin B12 or iron) and to screen for underlying autoimmune conditions.

While there is currently no cure for primary CIPO, the goal of treatment is to maintain nutrition and manage discomfort. The British Society of Gastroenterology suggests several approaches:

Prokinetic Medications

Drugs like erythromycin or prucalopride may be prescribed to stimulate the nerves and muscles of the gut to move more effectively.

Dietary Modifications

Patients are often advised to eat small, frequent meals that are low in fibre and fat, as these are easier for a sluggish gut to process. Liquid supplements may be necessary to ensure adequate caloric intake.

Managing Secondary Issues

If stagnant waste leads to Small Intestinal Bacterial Overgrowth (SIBO), courses of antibiotics may be required to reduce gas and bloating.

If you are experiencing persistent bloating, abdominal pain, or a change in bowel habits, it is important to seek medical advice. You can speak to a GP online to discuss your symptoms in a calm, factual environment. An online doctor can help by:

• Reviewing your current medications to see if they are contributing to gut slowing.
• Ordering initial blood tests to rule out common causes of digestive distress.
• Providing a referral to a private or NHS gastroenterologist for specialist motility testing.
• Issuing sick notes if symptoms are impacting your ability to work.
