What is the definition of stenosis?

Stenosis refers to the narrowing of a body opening or passage, which can occur in various parts of the body, such as blood vessels or the spinal canal. This narrowing can lead to reduced blood flow or constriction of a passage, potentially resulting in symptoms depending on the location and severity of the stenosis. In medical terms, recognizing stenosis is crucial because it can impact the functionality of the organ or structure involved, leading to various health issues. This definition aligns with the accepted medical terminology regarding the condition and its implications for patient care.
