What does the term '-stenosis' refer to?

The term '-stenosis' refers specifically to the narrowing of a tubular structure in the body, such as a blood vessel or an organ's passageway. This suffix is derived from the Greek word 'stenos,' which means narrow. In medical terminology, it is commonly used to describe conditions where a narrowing occurs that impedes normal function or flow, such as in cases of spinal stenosis (narrowing of the spinal canal) or aortic stenosis (narrowing of the aortic valve opening). Understanding this term is essential, especially in contexts where complications arise due to restricted movement or flow, highlighting the implications of such conditions on patient health and treatment options.
