stenózisa

Stenózisa is a medical term referring to the abnormal narrowing of a bodily passage or structure. This narrowing can affect various parts of the body, including blood vessels, airways, ducts, and the digestive tract. The causes of stenosis are diverse and can include congenital abnormalities, inflammation, injury, infection, or the presence of tumors.

When a passage becomes stenosed, it restricts the normal flow of substances through it. For instance, vascular stenosis can impede blood flow, potentially leading to pain, organ damage, or stroke. Airway stenosis can cause breathing difficulties, while stenosis in the digestive system can result in problems with nutrient absorption or the passage of food.

Symptoms associated with stenosis vary greatly depending on the location and severity of the narrowing. Common symptoms can include pain, swelling, altered function of the affected organ, and in severe cases, organ failure. Diagnosis typically involves medical imaging techniques such as X-rays, ultrasound, CT scans, or MRI, as well as physical examinations and symptom assessment.

Treatment for stenosis aims to widen the narrowed passage or bypass it to restore normal function. Options may include minimally invasive procedures like angioplasty and stenting, surgical interventions to remove blockages or reconstruct the affected area, or medication to manage underlying causes like inflammation. The prognosis for stenosis depends on its cause, location, and the effectiveness of treatment.
