What term refers to the narrowing of the lumen of the intestines?

The term that refers to the narrowing of the lumen of the intestines is stenosis. Stenosis occurs when the passage within a tubular structure becomes constricted, which can lead to difficulties in the passage of materials, such as food or waste, through the intestines. This condition may be due to a variety of factors, including inflammation, scar tissue formation, tumors, or congenital abnormalities.

In the context of gastrointestinal health, recognizing stenosis is crucial because it can lead to symptoms such as abdominal pain, bloating, or obstruction. If not properly addressed, it can cause complications like bowel obstruction, which can be a medical emergency. Understanding the specific term for this condition aids in clear communication among healthcare professionals and supports effective diagnosis and treatment planning.
