Last Updated: Aug 06, 2021

What is Dysentery?

Dysentery is a medical condition which is characterized by an intestinal inflammation inside the colon which can result to chronic diarrhea with blood or mucus in the feces. Dysentery can be fatal and can also cause death due to dehydration if the lost fluids from the body is not replaced quickly. Dysentery is more common in children below the age of 11 years old and people living in the developing nations.

Types of dysentery:

There are two types of dysentery that are approved by the World Health Organization.

What is the difference between diarrhea and dysentery?

Diarrhoea is the condition characterized by frequent discharge of loose and water-like stool. The causative organisms in this case may be viruses or other parasites. On the other hand, dysentery is a bacterial infection and it is characterized by an inflammation in the colon part of the intestine, leading to the severe diarrhoea like condition with a discharge of blood and mucus in the stool.
