Cathartic
Cathartic
Cathartic (pronunciation: /kəˈθɑːrtɪk/) is a term used in medicine to describe a substance that accelerates defecation. This term is often used interchangeably with the term laxative.
Etymology
The term "cathartic" originates from the Greek word "kathartikos", which means "capable of cleansing or purifying".
Usage
Cathartics are used in the treatment of constipation and in certain bowel preparation procedures prior to medical examinations or surgery. They work by increasing the water content and volume of the stool, which helps to stimulate bowel movements.
Types of Cathartics
There are several types of cathartics, including:
- Bulk-forming laxatives: These work by absorbing water to form a soft, bulky stool.
- Stimulant laxatives: These stimulate the lining of the intestine to hasten the passage of stool.
- Osmotic laxatives: These draw water into the intestine to encourage bowel movement.
- Stool softeners: These add water to the stool to make it softer and easier to pass.
Related Terms
- Purgative: A stronger type of cathartic that causes rapid evacuation of the bowels.
- Emetic: A substance that induces vomiting, which can also be considered a form of catharsis.
