Adhesions are bands or sheets of fibrous (scar-like) tissue that form between two surfaces inside the body, such as organs or tissues, that are normally separate, causing them to stick together. They most commonly develop in body cavities, such as the abdomen, where organs are expected to move freely but become tethered by scar tissue. Adhesions often occur as a result of surgery, inflammation, infection, or injury. While many adhesions remain asymptomatic, they can lead to complications such as pain, organ dysfunction, bowel obstruction, or infertility (in the pelvic region) when they distort normal anatomy or restrict movement. Preventing or managing adhesions can be challenging, as surgical procedures themselves increase the risk of adhesion formation, and many diagnostic tests cannot definitively detect them without direct visualization.
