Dilation vs. Dilatation: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on November 23, 2023
Dilation refers to the act of expanding or stretching, while dilatation often implies a pathological or abnormal expansion.

Key Differences

Dilation is commonly used in various contexts to describe the process of widening or expanding, especially in a physical or mechanical sense. Dilatation, while similar, is often reserved for specific medical contexts, referring to the abnormal enlargement or stretching of an organ or structure.
