Intestinal Pseudo Obstruction

Intestinal pseudo-obstruction (false blockage) is a condition in which there are symptoms of intestinal blockage without any physical signs of a blockage. In primary intestinal pseudo-obstruction, the small or large intestines lose their ability to contract and push food, stool, and air through the gastrointestinal tract. There is no known cause for this condition.

Although there is no actual blockage, symptoms are still present, which include cramps, stomach pain, nausea, vomiting, bloating, fewer bowel movements than usual, and loose stools. Bacterial infections, malnutrition, and muscle problems in other parts of the body can also occur over time. Some people with intestinal pseudo-obstruction also have bladder problems.

Some diseases that affect muscles and nerves such as lupus erythematosus, scleroderma, or Parkinson’s disease can cause symptoms of pseudo-obstruction. When a disease causes the symptoms, the condition is called secondary intestinal pseudo-obstruction. Medications that affect muscles and nerves such as opiates and antidepressants might also cause secondary pseudo-obstruction.

To diagnose the condition, the doctor will take a complete  medical history, do a physical exam, and take x rays. The main treatment is nutritional support (intravenous feeding) to prevent malnutrition and antibiotics to treat bacterial infections. Medicine might also be given to help with intestinal muscle problems. In severe cases, surgery to remove part of the intestines might be necessary.
