Ileus is a condition in which the normal movement of food through the small intestine is disrupted, leading to a blockage in the digestive tract. This blockage can cause abdominal pain, bloating, nausea, vomiting, and constipation. There are several types of ileus, including mechanical ileus, which is caused by a physical obstruction in the intestine, and neurogenic ileus, which is caused by a problem with the nerve signals that control the movement of food through the digestive tract.

Common causes of mechanical ileus include hernias, tumors, and abdominal surgery, while neurogenic ileus can be caused by conditions such as spinal cord injury, nerve damage, and certain medications.

Diagnosis of ileus typically involves a physical exam, medical history, and imaging tests such as an X-ray, CT scan, or abdominal ultrasound. Treatment depends on the underlying cause of the ileus and may involve removing the blockage, managing symptoms with medications, or in severe cases, surgery.

It is important to seek medical attention if you experience symptoms of ileus, as untreated blockages can lead to serious complications, such as infection, tissue death, and perforation of the intestine.
