A medical condition called diarrhoea is typified by loose or watery feces that come thrice daily. Diarrhoea is one of the most common ailments worldwide, affecting people of all ages. On the other hand, dysentery is a more serious condition characterised by blood and mucus in the stools.


Various factors, including infections, food poisoning, certain medications, and food intolerances, cause both conditions. Understanding the causes, symptoms, and treatments of diarrhoea is crucial in order to effectively manage and alleviate its impact on individuals' health and well-being.

What is Diarrhoea?

Diarrhoea is characterized by having at least three loose, liquid, or watery bowel movements daily. It is a common ailment that can last a few days and result in dehydration due to fluid loss. Dehydration symptoms frequently start with irritability and a lack of the skin's usual stretchiness. If the illness develops, it can include decreased urine production, skin discoloration, a quick heartbeat, and less attentiveness.

What is Dysentery?

Dysentery is an illness marked by intestinal inflammation, primarily in the colon, which causes bloody diarrhoea. It is a type of gastroenteritis that can cause dehydration, a fever, stomach pain, and the feeling that one hasn't defecated all the way. Dysentery is usually spread by contaminated food or water contaminated with feces due to poor sanitation.

What Signs of Diarrhoea and Dysentery are There?
