Stenosis is a medical condition where a part of the body narrows, which can restrict the flow of fluids or the movement of structures. This narrowing can occur in various areas, such as the spine, heart, or blood vessels. When stenosis happens, it can lead to symptoms like pain, weakness, or difficulty in movement, depending on the affected area. There are different types of stenosis, including spinal stenosis and aortic stenosis. Treatment options vary based on severity and location, ranging from physical therapy to surgical procedures. Early diagnosis and management are essential to prevent complications and improve quality of life.
