niedroznosc

Niedroznosc, often written niedroznosc in text without diacritics, is a condition in which a passage or conduit becomes blocked, preventing the normal flow of air, liquids, or other substances. The concept applies in medicine, engineering, and everyday language, where it indicates an obstruction or occlusion that hinders passage.

In medicine, niedroznosc is most commonly used to describe obstructions in the body's passages. Common sites include the gastrointestinal tract (niedroznosc jelit), the biliary or urinary systems, and the nasal passages. It can be caused by physical blockages such as tumors, stones, fecal impaction, foreign bodies, or by impaired motility without a physical block (functional niedroznosc, for example ileus).

Causes are typically categorized as mechanical (physical blockage) or functional (loss of coordinated movement). Mechanical obstructions may result from tumors, stones, strictures, or inflammatory swelling. Functional niedroznosc arises from disrupted peristalsis or nerve signaling, leading to impaired propulsion of contents.

Diagnosis relies on clinical assessment aided by imaging and laboratory tests. Symptoms vary by site but can include abdominal pain, vomiting, inability to pass stool or gas, nasal congestion, or decreased urine output. Imaging modalities such as ultrasound, X-ray, or CT provide visualization of the obstruction and its location.

Treatment aims to relieve the blockage and restore function. Management is site-specific and ranges from supportive care and decompression to endoscopic or surgical intervention for mechanical obstructions. Early evaluation is important to address potential complications and determine appropriate therapy. See also patency and obstruction.
