The medical term "dilat/o" is a combining form, meaning it's a word part that combines with other word parts to create a medical term. It specifically refers to dilation, or the process of widening or enlarging an opening or vessel. Understanding "dilat/o" is crucial for interpreting many medical terms related to the cardiovascular system, gastrointestinal tract, and other body systems.

What Does Dilat/o Mean?

At its core, "dilat/o" means "widening," "expansion," or "stretching." In medical contexts, this usually refers to the enlargement of a body part or passage. For example, dilation of the pupils means the pupils of the eyes have become wider. This widening can occur due to various physiological processes or medical interventions.

Medical Terms Using Dilat/o

Many medical terms incorporate "dilat/o," providing crucial information about a specific condition or procedure. Let's explore some examples:

Cardiovascular System

Cardiomegaly: While not directly using "dilat/o," cardiomegaly refers to an enlargement of the heart. This is a condition where the heart's chambers widen, often due to underlying conditions.
Dilatation of the arteries: This term signifies the enlargement of the arteries. Atherosclerosis, a buildup of plaque in the arteries, can lead to this condition.

Gastrointestinal Tract

Dilatation of the esophagus: This refers to the widening of the esophagus, the tube connecting the mouth to the stomach. It can be caused by various factors, including certain medical conditions and swallowing difficulties.
