Stricture is defined as which of the following?

Explanation:
Stricture means an abnormal narrowing of a duct, tube, or passage. It describes a reduced diameter of the lumen, which can impede the flow of fluids, air, or other contents through that channel. This narrowing is often the result of scar tissue or cicatricial change after inflammation, injury, or surgery, though the term itself focuses on the change in size rather than the inflammation process. It’s different from widening (dilation), a blockage (which is an obstruction), or pure inflammation. Clinically you might see examples like urethral stricture or esophageal stricture, where the narrowed segment leads to symptoms such as reduced flow or swallowing difficulties.
