Intestinal Adhesions: Do They Cause Pain When Lying Down?

Intestinal adhesions can cause discomfort or pain in various positions, including lying down. Whether or not pain occurs depends on the severity and nature of the adhesion. If an obstruction is triggered by the adhesion, pain may be experienced regardless of whether a person is standing or lying flat. These adhesions typically involve the small intestine within the abdominal cavity and are commonly caused by post-surgical complications, inflammation, or internal bleeding.

Understanding How Intestinal Adhesions Develop

Post-surgical adhesions are the most frequent cause of intestinal blockages. After abdominal surgery, bands of tissue may form between loops of the intestine or between the intestine and other organs. This abnormal connection can partially or completely restrict the movement of the intestines. As a result, when food moves into the intestinal tract, it can accumulate above the affected area, unable to pass through smoothly.

What Happens During a Blockage?

When the upper section of the bowel becomes overly full, it can lead to bloating and increased pressure. This pressure can worsen the adhesion at the lower end of the affected bowel loop, causing a sharp angle that further restricts movement. In severe cases, this can result in localized bowel paralysis or even tissue death, both of which cause intense pain.

Why Position Doesn't Always Matter

Because of the physical restriction caused by adhesions, pain can occur in any body position. The discomfort may intensify with sudden movements or changes in posture, which can lead to complications such as volvulus—where the bowel twists on itself—increasing the risk of serious intestinal issues. Therefore, whether a person is standing or lying down, pain from intestinal adhesions and related obstructions can still be present and quite pronounced.
